The break-even point is the level of sales at which a business’s total income equals its total costs. At break-even, the business has covered its fixed and variable costs but has not yet made a profit.
The standard formula is:
Break-even point in units = Fixed costs ÷ Contribution per unit
Contribution per unit is calculated as:
Contribution per unit = Selling price per unit − Variable cost per unit
For example, if a product sells for £30, has variable costs of £12 and the business has fixed costs of £9,000:
- Contribution per unit: £30 − £12 = £18
- Break-even point: £9,000 ÷ £18 = 500 units
The business must therefore sell 500 units to break even. The 501st unit begins contributing towards profit, provided the selling price and costs remain unchanged.
The same principle can be used for products, services, subscriptions, hourly work, retail businesses, online stores and side hustles. Start Up Loans, part of the British Business Bank group, uses the same fixed-cost and contribution formula in its explanation of how to calculate a break-even point.
What Is a Break-Even Point?
A break-even point shows the amount a business must sell before it stops making an operating loss.
At the break-even point:
- Total sales revenue equals total costs.
- Fixed costs have been covered.
- Variable costs have been covered.
- Operating profit is zero.
- Operating loss is zero.
A business selling below its break-even point will normally make a loss. A business selling above it should begin to make a profit, assuming its prices and costs remain consistent.
Break-even analysis can be used to assess:
- Whether a business idea appears commercially viable
- How many products must be sold
- How many billable hours are required
- Whether a price is high enough
- How a rent increase could affect profitability
- Whether hiring an employee is affordable
- How discounts change the sales target
- Whether a new product is financially sustainable
- How much revenue is needed to reach a target profit
Break-even is a planning calculation rather than a guarantee. Actual results may differ because sales volumes, prices, returns, wastage and operating costs can change.
What Is the Break-Even Point Formula?
There are two main formulas: one calculates break-even in units, while the other calculates the value of sales revenue required.
Break-even point in units
Fixed costs ÷ Contribution per unit = Break-even units
Where:
Contribution per unit = Selling price − Variable cost per unit
Break-even point in sales revenue
Fixed costs ÷ Contribution margin ratio = Break-even sales revenue
Where:
Contribution margin ratio = Contribution ÷ Sales revenue
The US Small Business Administration and UK accounting platforms use the same core formula: fixed costs divided by the difference between the selling price and variable cost.
The result should normally be rounded up to the next complete unit. A business cannot usually sell 417.3 physical products, so it would need to sell at least 418.
Enter the business costs and selling price to estimate the units and sales revenue required to break even.
Select the period used for fixed costs and planning figures.
Use figures from the same period and apply VAT consistently.
Include rent, insurance, software, salaries and other costs that do not change directly with sales.
Enter the net price retained by the business and apply VAT consistently.
Include direct materials, packaging, transaction fees and sales commission.
Test a target profit or expected sales level.
The break-even estimate will update immediately.
What Information Is Needed to Calculate Break-Even?
A basic calculation requires three figures:
- Total fixed costs
- Selling price per unit
- Variable cost per unit
The accuracy of the result depends on the accuracy of these inputs. Missing costs can make a weak business idea appear more profitable than it really is.
What Are Fixed Costs?
Fixed costs are expenses that do not normally change directly with each additional product sold or service delivered.
Examples include:
| Fixed cost | Example |
| Premises | Rent and business rates |
| Insurance | Public liability or professional indemnity cover |
| Software | Accounting, booking or design subscriptions |
| Administration | Regular bookkeeping and office costs |
| Salaried staff | Employees paid regardless of weekly sales |
| Equipment finance | Regular lease or hire-purchase payments |
| Marketing | Fixed monthly advertising retainers |
| Utilities | The basic standing or minimum charge |
| Professional costs | Regular accountancy or compliance support |
| Communications | Business telephone and internet contracts |
Fixed does not necessarily mean permanent. Rent may rise, an insurance policy may renew at a different price and software subscriptions may change.
A cost is described as fixed because it does not immediately rise or fall in direct proportion to the number of units sold during the period being analysed.
What Are Variable Costs?
Variable costs increase or decrease according to the quantity sold or work completed.
Examples include:
| Variable cost | Example |
| Materials | Wax, ingredients, timber or fabric |
| Stock | Products purchased for resale |
| Packaging | Boxes, labels and wrapping |
| Delivery | Postage paid on each order |
| Transaction charges | Card or marketplace fees |
| Sales commissions | Percentage paid on each sale |
| Piece-rate labour | Labour paid for each unit produced |
| Consumables | Items used during each customer job |
| Royalties | Fees charged per sale |
| Returns | Expected refund or replacement cost per unit |
For example, a candle maker may have a fixed annual insurance cost but incur wax, fragrance, jars, labels and marketplace charges for each candle sold.
The cost structure shown in the figures for a candle-making business in the UK demonstrates why materials, packaging and selling fees must be included before calculating contribution.
What Are Semi-Variable Costs?
Some costs contain both fixed and variable elements.
Examples include:
- Electricity with a fixed standing charge and usage-based charge
- Telephone contracts with a fixed fee and additional usage costs
- Vehicle costs with fixed insurance and variable fuel
- Staff costs with fixed salaries and sales-based bonuses
- Warehouse costs with a base rental fee and volume charges
A more accurate break-even calculation separates these costs into:
- The fixed element, which is included in total fixed costs
- The variable element, which is allocated to each unit or sale
If separation is difficult, a business can estimate the variable part using historical records and review the estimate regularly.
What Does Contribution Mean in Break-Even Analysis?
Contribution is the amount left from a sale after its variable costs have been deducted.
That remaining amount contributes towards:
- Paying fixed costs
- Producing profit after fixed costs have been covered
Suppose a product sells for £50 and has variable costs of £30:
£50 selling price − £30 variable costs = £20 contribution
Each sale contributes £20 towards fixed costs.
If fixed costs are £10,000:
£10,000 ÷ £20 = 500 units
The first 500 units cover the fixed costs. Further units contribute £20 each towards operating profit, assuming costs and prices remain the same.
Contribution is not the same as profit because fixed costs have not yet been deducted.
How Do You Work Out Break-Even Point Step by Step?
The following process can be used for most product-based businesses.
Step 1: Choose the Calculation Period
Decide whether the break-even point will be calculated monthly, quarterly or annually.
All figures must cover the same period.
For example, an annual calculation should use:
- Annual rent
- Annual insurance
- Annual salaries
- Annual software costs
- Annual expected sales
Mixing monthly fixed costs with annual sales figures will produce an incorrect result.
Step 2: Add the Fixed Costs
List every cost that must be paid even if no products are sold.
Example:
| Annual fixed cost | Amount |
| Workshop rent | £6,000 |
| Insurance | £600 |
| Software and telephone | £1,200 |
| Advertising | £1,800 |
| Equipment lease | £2,400 |
| Accountancy | £1,000 |
| Other fixed administration | £1,000 |
| Total fixed costs | £14,000 |
Step 3: Calculate the selling price per unit
Use the expected average selling price after normal discounts.
If a product is advertised at £40 but is usually sold for £36 after promotions, £36 may be the more realistic figure.
Do not use an unrealistic full price simply because it produces a more attractive break-even result.
Step 4: Calculate the Variable Cost Per Unit
Include every cost that arises directly from making or completing one sale.
Example:
| Variable cost per unit | Amount |
| Materials | £8.00 |
| Packaging | £1.50 |
| Transaction fee | £1.00 |
| Delivery contribution | £2.50 |
| Sales commission | £1.00 |
| Total variable cost | £14.00 |
Step 5: Calculate Contribution Per Unit
If the selling price is £35:
£35 − £14 = £21 contribution per unit
Step 6: Divide Fixed Costs by Contribution
£14,000 ÷ £21 = 666.67 units
The result should be rounded up:
Break-even point = 667 units
Step 7: Convert the Result Into Sales Revenue
667 units × £35 = £23,345
The business needs to generate approximately £23,345 in sales to reach break-even under these assumptions.
What Is a Simple Break-Even Point Example?
Consider a small business selling reusable water bottles.
- Selling price: £25
- Variable cost per bottle: £10
- Annual fixed costs: £6,000
Calculate contribution
£25 − £10 = £15
Each bottle contributes £15 towards fixed costs and profit.
Calculate break-even units
£6,000 ÷ £15 = 400 bottles
Calculate break-even revenue
400 × £25 = £10,000
The business breaks even after selling 400 bottles, producing £10,000 in revenue.
The result assumes:
- Every bottle is sold for £25.
- Variable cost remains £10.
- Fixed costs remain £6,000.
- There are no refunds, discounts or damaged units.
- All relevant costs have been included.
How Do You Work Out Break-Even Sales Revenue?
A business selling many different products may find it easier to calculate break-even as a revenue figure rather than a number of units.
The formula is:
Break-even revenue = Fixed costs ÷ Contribution margin ratio
Suppose a business has:
- Sales revenue: £50,000
- Variable costs: £30,000
- Fixed costs: £12,000
Step 1: Calculate Total Contribution
£50,000 − £30,000 = £20,000
Step 2: Calculate the Contribution Margin Ratio
£20,000 ÷ £50,000 = 0.40
The contribution margin ratio is 40%.
Step 3: Calculate Break-even Revenue
£12,000 ÷ 0.40 = £30,000
The business must generate £30,000 in sales revenue to break even.
The same result can be expressed as:
Fixed costs ÷ Contribution margin percentage
When using a percentage in a calculator, 40% must be entered as 0.40.
How Do You Work Out Break-Even for a Service Business?
A service business can calculate break-even using billable hours, appointments, projects or customers.
The formula is:
Fixed costs ÷ Contribution per billable hour = Break-even billable hours
Suppose a virtual assistant charges £45 per hour.
- Hourly customer price: £45
- Variable cost per billable hour: £8
- Monthly fixed costs: £3,700
Calculate Contribution Per Hour
£45 − £8 = £37
Calculate Break-even Hours
£3,700 ÷ £37 = 100 hours
The business must invoice 100 hours per month to cover its monthly fixed and variable costs.
If the person works 46 weeks each year, this target should be converted into realistic working weeks rather than divided across all 52 weeks without adjustment.
Service businesses should also account for non-billable time, including:
- Marketing
- Quoting
- Administration
- Bookkeeping
- Training
- Customer communication
- Travelling
- Unpaid corrections
- Annual leave
- Sickness
The pricing model used for a UK virtual assistant side hustle shows why the customer’s hourly rate is not the same as the owner’s effective hourly earnings.
How Do You Calculate Break-Even for a Gardener or Tradesperson?
A gardener, painter, cleaner or other tradesperson can use billable hours or completed jobs.
Suppose a self-employed gardener has:
- Monthly fixed business costs: £1,800
- Customer rate: £35 per hour
- Variable cost per billable hour: £5
Contribution per billable hour:
£35 − £5 = £30
Break-even hours:
£1,800 ÷ £30 = 60 billable hours
The gardener must invoice for 60 hours during the month to cover the included business costs.
However, the result will not cover the owner’s required personal income unless that amount has been added as a target profit.
For example, if the gardener wants the business to generate £2,500 before personal tax in addition to covering £1,800 of fixed costs:
£1,800 fixed costs + £2,500 target profit = £4,300
£4,300 ÷ £30 = 143.34 hours
At least 144 billable hours would be needed to cover the business costs and produce the £2,500 target.
How Should a Sole Trader Include Their Own Pay?
A sole trader’s personal drawings are not normally treated as a business expense when calculating taxable profit. HMRC states that money taken from the business for personal use is not an allowable expense.
However, the owner still needs enough profit to meet personal living costs.
For practical business planning, the required owner income should normally be added as a target profit, rather than incorrectly classified as a fixed operating cost.
The formula becomes:
Fixed costs + Required owner profit ÷ Contribution per unit
Correctly presented:
(Fixed costs + Required owner profit) ÷ Contribution per unit
Suppose a sole trader has:
- Fixed business costs: £20,000
- Required profit before personal tax: £35,000
- Contribution per sale: £50
The required number of sales is:
(£20,000 + £35,000) ÷ £50 = 1,100 sales
The ordinary operating break-even point would be only 400 sales:
£20,000 ÷ £50 = 400 sales
This distinction matters. A business can technically break even while still failing to provide its owner with a sustainable income.
Business owners should separately review which costs qualify for tax purposes. HMRC’s allowable self-employed expenses cover business-related running costs, while the detailed explanation of expenses that can be claimed when self-employed provides practical UK examples.
How Does Owner Pay Work for a Limited Company?
A limited company is legally separate from its owner.
A director’s salary paid through payroll may be a company expense, subject to the normal tax and employment rules. Dividends, however, are distributions of profit and are not treated as ordinary operating expenses.
A limited company’s break-even calculation may therefore include:
- Director salary
- Employer’s National Insurance
- Workplace pension contributions
- Employee wages
- Payroll administration
It would not normally include planned dividends as a fixed operating cost. A desired dividend or retained profit target can instead be included in an extended target-profit calculation.
Complex director-remuneration calculations should be checked with an accountant because the accounting, payroll and tax treatment can differ from ordinary management planning.
How Do You Calculate Break-Even for Multiple Products?
A business selling several products cannot always use one simple contribution figure.
One approach is to calculate a weighted average contribution based on the expected sales mix.
Suppose a business sells two products:
| Product | Sales mix | Contribution per unit |
| Product A | 60% | £12 |
| Product B | 40% | £20 |
Calculate the Weighted Contribution
Product A:
£12 × 60% = £7.20
Product B:
£20 × 40% = £8.00
Weighted average contribution:
£7.20 + £8.00 = £15.20
If fixed costs are £15,200:
£15,200 ÷ £15.20 = 1,000 total units
Based on the expected sales mix, the break-even volume would be:
- 600 units of Product A
- 400 units of Product B
This calculation depends on the sales mix remaining reasonably stable. If customers buy more of the lower-contribution product, the actual break-even point will rise.
A business should therefore calculate different scenarios, such as:
- Expected sales mix
- Lower-margin sales mix
- Higher-margin sales mix
- Discounted sales mix
How Do You Calculate Break-Even for a Home Baking Business?
Consider a home baker selling boxes of brownies.
- Selling price per box: £24
- Ingredients: £6
- Packaging: £2
- Payment fee: £1
- Variable energy cost: £1
- Total variable cost: £10
- Monthly fixed costs: £700
Contribution per box:
£24 − £10 = £14
Break-even boxes:
£700 ÷ £14 = 50 boxes
Break-even revenue:
50 × £24 = £1,200
The baker must sell 50 boxes per month to cover the included business costs.
If the baker wants a further £1,400 monthly profit:
(£700 + £1,400) ÷ £14 = 150 boxes
The business would need to sell 150 boxes to cover its operating costs and achieve the target profit.
Food sellers must also include wastage, unsold products, delivery, market fees and packaging. The cost breakdown for a home baking side hustle provides examples of expenses that can materially change the contribution per order.
How Do You Add a Target Profit?
Break-even only identifies the point at which profit is zero.
To calculate how many sales are required to reach a specific profit target, use:
Target sales volume = (Fixed costs + Target profit) ÷ Contribution per unit
Suppose a business has:
- Fixed costs: £18,000
- Target profit: £30,000
- Selling price: £80
- Variable cost: £32
Contribution per unit:
£80 − £32 = £48
Required sales:
(£18,000 + £30,000) ÷ £48 = 1,000 units
The business must sell:
- 375 units to reach operating break-even
- 1,000 units to make the £30,000 target profit
Break-even calculation:
£18,000 ÷ £48 = 375 units
What Is the Margin of Safety?
The margin of safety shows how far actual or forecast sales are above the break-even point.
The formula is:
Margin of safety = Actual sales − Break-even sales
The percentage formula is:
Margin of safety percentage = Margin of safety ÷ Actual sales × 100
Suppose:
- Actual annual sales: £100,000
- Break-even sales: £70,000
Margin of safety:
£100,000 − £70,000 = £30,000
Margin of safety percentage:
£30,000 ÷ £100,000 × 100 = 30%
Sales could fall by approximately 30% before the business reaches its calculated break-even point.
A small margin of safety can indicate that the business is vulnerable to:
- Seasonal demand
- Customer losses
- Supplier price increases
- Unexpected repairs
- Discounts
- Refunds
- Economic disruption
A higher margin of safety generally provides more protection, but the quality and reliability of the assumptions still matter.
How Does a Price Change Affect Break-Even?
A lower price normally reduces contribution and increases the number of sales needed.
Suppose:
- Fixed costs: £10,000
- Variable cost: £20
- Original selling price: £50
Original contribution:
£50 − £20 = £30
Original break-even point:
£10,000 ÷ £30 = 333.33
The business needs 334 sales.
If the price is reduced to £40:
£40 − £20 = £20 contribution
New break-even point:
£10,000 ÷ £20 = 500 sales
A 20% price reduction has increased the required volume from 334 to 500 units.
The business would need approximately 50% more sales to reach break-even.
This is why discounts should be tested using contribution rather than judged only by the percentage reduction in the selling price.
How Does a Cost Increase Affect Break-Even?
An increase in fixed or variable costs raises the break-even point unless the business also increases prices or improves efficiency.
Suppose:
- Fixed costs: £12,000
- Selling price: £60
- Variable cost: £30
- Contribution: £30
Original break-even point:
£12,000 ÷ £30 = 400 units
If variable costs increase to £36:
£60 − £36 = £24 contribution
New break-even point:
£12,000 ÷ £24 = 500 units
The business must sell an additional 100 units to cover the cost increase.
Should VAT Be Included in a Break-Even Calculation?
VAT-registered businesses should normally use figures that exclude recoverable VAT when measuring revenue and costs for management-accounting purposes.
For example, if a VAT-registered business charges £120 including standard-rate VAT:
- Net selling price: £100
- VAT collected: £20
The £20 is generally collected for HMRC rather than retained as business revenue.
Costs should also be treated consistently. If input VAT is recoverable, the net cost is normally used. If VAT cannot be recovered, it may remain part of the cost.
A non-VAT-registered business will generally include VAT paid to suppliers within its cost because it cannot ordinarily reclaim that VAT.
The calculation should not mix:
- VAT-inclusive sales with VAT-exclusive costs
- VAT-exclusive sales with VAT-inclusive costs
HMRC states that compulsory VAT registration is generally required when taxable turnover exceeds £90,000 over a rolling 12-month period, although other registration rules can apply. (gov.uk)
Businesses near the threshold should recalculate prices and break-even levels before and after VAT registration.
Is Tax Included in the Break-Even Point?
A standard operating break-even calculation is usually completed before Income Tax or Corporation Tax.
This is because profit-based taxes depend on the amount of taxable profit. At a true accounting break-even point, the operating profit being measured is zero.
However, businesses may still need to plan for:
- VAT payments
- PAYE deductions
- Employer’s National Insurance
- Business rates
- Loan repayments
- Previous tax liabilities
- Payments on account
- Personal tax on other income
A separate cash-flow forecast should therefore be used alongside break-even analysis.
Is Break-Even the Same as Cash Flow?
No. Break-even and cash flow measure different things.
Break-even considers whether income is sufficient to cover costs over a period. Cash flow measures when money actually enters and leaves the business.
A profitable business may still run short of cash where:
- Customers pay invoices late
- Large amounts of stock are purchased in advance
- VAT must be paid before customer invoices are collected
- Loan capital repayments are due
- Equipment requires an upfront deposit
- Seasonal income arrives after costs have been paid
- Tax relates to profits earned in an earlier period
The British Business Bank explains that a cash-flow forecast predicts money moving into and out of the business over a defined period.
Break-even analysis should therefore be used with:
- A cash-flow forecast
- A sales forecast
- A profit-and-loss forecast
- A personal survival budget
- A contingency plan
What Is the Difference Between Accounting and Cash Break-Even?
An accounting break-even calculation can include non-cash expenses such as depreciation.
A cash break-even calculation focuses on cash operating costs and may exclude some non-cash accounting charges.
However, cash break-even may include cash commitments that are not fully shown as profit-and-loss expenses, such as the capital portion of loan repayments.
The appropriate version depends on the decision being made.
| Calculation | Main purpose |
| Accounting break-even | Measuring whether revenue covers accounting costs |
| Cash break-even | Measuring whether operating cash inflows cover cash outflows |
| Target-profit analysis | Measuring sales needed for a desired profit |
| Payback period | Estimating how long an initial investment takes to recover |
These figures should not be used interchangeably without understanding what each includes.
How Should Start-Up Costs Be Treated?
Start-up costs may include:
- Equipment
- Deposits
- Initial stock
- Website development
- Legal fees
- Professional advice
- Branding
- Launch advertising
- Registration or licence costs
Some start-up costs become ordinary business expenses, while others may be capital expenditure or refundable deposits.
For management planning, a business can either:
- Include the entire relevant start-up cost in the first period’s fixed-cost calculation; or
- Spread the cost over the period in which the business expects to recover it.
The chosen approach should be clearly labelled.
For example, if a business spends £12,000 on initial equipment and wants to recover the investment over three years, it may add £4,000 per year to its internal target.
This does not necessarily match the amount allowed as a tax deduction. Tax treatment should be checked separately.
How Often Should Break-Even Be Recalculated?
A break-even point should be reviewed whenever a major assumption changes.
Common triggers include:
- Rent increases
- Wage changes
- Supplier price rises
- New marketplace fees
- VAT registration
- Hiring an employee
- Buying equipment
- Changing the selling price
- Introducing discounts
- Launching a new product
- Changing the product mix
- Entering a new location
- Experiencing higher refunds or wastage
- Receiving more accurate cost information
A quarterly review may be appropriate for a stable business. A new or rapidly changing business may need to update the calculation monthly.
What Are the Most Common Break-Even Mistakes?
Leaving Out the Owner’s Required Income
A sole trader may calculate operating break-even but forget that the business must also generate enough profit to support them.
The required owner income should be added as a target profit.
Using Turnover Instead of Contribution
Total sales cannot be used to pay fixed costs because variable costs must first be deducted.
The correct denominator is contribution, not selling price.
Ignoring Non-billable Time
Service businesses often assume every working hour can be invoiced. Time spent travelling, marketing, quoting and completing administration reduces billable capacity.
Mixing Monthly and Annual Figures
All income and cost figures must relate to the same period.
Forgetting Payment Fees
Card processors, online marketplaces and delivery platforms may charge a percentage plus a fixed fee on every transaction.
Ignoring Wastage and Refunds
Damaged products, failed batches, refunds and replacements can reduce the real contribution per sale.
Using the Advertised Price
The average price after discounts, offers, commissions and refunds may be lower than the headline price.
Treating Drawings as a Business Expense
A sole trader’s personal withdrawals are not ordinary business costs. Required personal income should be included as a target profit.
Ignoring VAT
VAT-registered businesses should normally use consistent net-of-VAT figures where VAT is recoverable.
Assuming Every Product Has the Same Margin
Different products can have very different contribution margins. A weighted calculation may be required.
Confusing Break-even With Cash Availability
A business can reach accounting break-even and still be unable to pay bills on time.
How Can a Business Lower Its Break-Even Point?
A business can reduce the required sales level by:
- Increasing prices
- Reducing variable costs
- Negotiating supplier discounts
- Reducing packaging costs
- Improving production efficiency
- Removing unprofitable products
- Lowering fixed overheads
- Renegotiating rent
- Cancelling unused software
- Reducing customer returns
- Increasing the proportion of high-margin sales
- Charging separately for delivery
- Introducing minimum order values
- Improving staff scheduling
- Reducing waste
- Increasing customer retention
Each change should be assessed for wider consequences.
For example, cheaper materials might reduce variable costs but increase returns or damage the business’s reputation. A price increase might improve contribution but reduce sales volume.
Scenario testing is more reliable than assuming that one change will automatically improve profit.

Final Summary
Knowing how to work out a break-even point gives a business a clear minimum sales target.
The standard calculation requires:
- Total fixed costs
- Selling price per unit
- Variable cost per unit
- Contribution per unit
The formula is:
Fixed costs ÷ Contribution per unit = Break-even point
A reliable calculation should also account for:
- Discounts
- Refunds
- Wastage
- Transaction charges
- Packaging
- Delivery
- Non-billable time
- VAT treatment
- Sales mix
- Owner income
- Seasonal demand
Break-even is not the same as sustainable profitability. A business must normally sell above its break-even point to fund owner income, tax, reinvestment, unexpected costs and future growth.
Anyone beginning regular commercial activity should also understand when they may need to register as a sole trader. A wider range of low-cost business models can be compared through the complete collection of UK side-hustle options.
Frequently Asked Questions
What is the formula for working out break-even?
The formula is fixed costs divided by contribution per unit. Contribution per unit is the selling price minus the variable cost per unit.
What does breaking even mean?
Breaking even means that total revenue equals total costs. The business has made neither an operating profit nor an operating loss.
What is contribution per unit?
Contribution per unit is the amount remaining from each sale after variable costs have been deducted. It is used to pay fixed costs and then generate profit.
What is an example of a break-even calculation?
If fixed costs are £10,000, the selling price is £50 and variable costs are £30, contribution is £20. The break-even point is £10,000 divided by £20, which equals 500 units.
How do you work out break-even sales revenue?
Divide fixed costs by the contribution margin ratio. The contribution margin ratio is total contribution divided by total sales revenue.
Should break-even be calculated monthly or annually?
Either period can be used, but all costs and sales figures must relate to the same period. Monthly calculations may be more useful for a new or seasonal business.
Are wages fixed or variable costs?
Regular salaries are commonly treated as fixed costs. Overtime, commissions or piece-rate labour may be variable. Some staffing costs are semi-variable.
Is rent a fixed cost?
Rent is normally treated as a fixed cost because it is payable regardless of the number of products sold during the period.
Is packaging a variable cost?
Packaging is normally a variable cost where each additional sale requires another box, label, envelope or container.
Should a sole trader include their own wage?
A sole trader does not normally deduct personal drawings as a business expense. Required owner income can be included as a target profit when planning the sales needed for a sustainable business.
Does break-even include tax?
Standard operating break-even is usually calculated before profit-based tax. VAT, payroll liabilities and other cash commitments may still need to be included in a separate cash-flow forecast.
Does break-even include VAT?
A VAT-registered business will normally use sales and recoverable costs excluding VAT. A non-VAT-registered business generally includes VAT paid within its costs.
What happens after the break-even point?
After fixed costs have been covered, each additional unit’s contribution normally increases operating profit, assuming prices and costs remain unchanged.
Can a business be profitable but have no cash?
Yes. Customers may pay late, stock may be purchased in advance or tax and loan payments may fall due before cash is collected.
How can a business reduce its break-even point?
It can increase prices, reduce fixed costs, lower variable costs, improve its sales mix, reduce waste or increase operational efficiency.
