How to Calculate Break-Even Point: Sales You Need to Cover Your Costs
Learning how to calculate break even point gives you one of the most useful numbers in your business: the level of sales you need just to cover your costs. Below that level you lose money; above it, each extra sale starts to contribute to profit. The calculation is simple once your costs are sorted correctly.
This guide sorts fixed and variable costs, then walks you through the calculation step by step so you can do it with your own figures. No borrowed benchmarks are used, because the right answer depends entirely on your own prices and costs.
Before You Calculate Break Even Point: Sort Your Costs
The first job in how to calculate break even point is sorting costs into two groups. Fixed costs stay broadly the same whether you sell a little or a lot, such as rent, insurance, and salaried wages. Variable costs rise and fall with each sale, such as stock, packaging, card fees, and hourly labour tied to orders.
| Cost | Usually Fixed or Variable? | Check for Your Business |
|---|---|---|
| Rent and insurance | Fixed | Same amount each month regardless of sales? |
| Stock and materials | Variable | Rises with each order or job? |
| Salaried wages | Mostly fixed | Paid the same in quiet and busy weeks? |
| Card and transaction fees | Variable | Charged per sale? |
| Utilities | Mixed | Split the steady part from the usage part |
| Delivery and packaging | Variable | Cost per order you can estimate? |
Be honest with mixed costs. Split them into a fixed part and a per-sale part as best you can, and note your assumption. A careful sort makes the rest of how to calculate break even point far more reliable. Our guide to business budget planning helps you gather these figures in one place.
How to Calculate Break Even Point in Five Steps
Follow these steps with a calculator and last month’s records. This is the standard method for how to calculate break even point in units, and the same figures also give you a sales-value version.
Step 1: Total Your Monthly Fixed Costs
Add up every fixed cost for a typical month. Use real bills and payroll figures, not guesses. Write the total down and keep the list, because you will update it whenever rent, wages, or subscriptions change.
Step 2: Find Your Price Per Unit
Use your average selling price for one unit, job, or standard service. If you sell many products at different prices, use a realistic average based on what you actually sold last month, weighted toward your best sellers.
Step 3: Find Your Variable Cost Per Unit
Add the stock, packaging, fees, and direct labour that one sale uses. Divide a month’s variable costs by the number of units sold if a per-unit figure is not obvious. Accuracy here matters most, so check it twice.
Step 4: Work Out Contribution Per Unit
Subtract the variable cost per unit from the price per unit. The result is the contribution: the amount each sale puts toward fixed costs. If contribution is zero or negative, no sales level will break even until price or variable costs change.
Step 5: Divide Fixed Costs by Contribution
Divide total fixed costs by contribution per unit. The answer is your break-even units for the month. Multiply by price if you want the break-even sales value. This final division is the moment how to calculate break even point turns into a target your team can understand and track weekly.
Using Your Break-Even Number Week to Week
A break-even figure is only useful if you act on it. Compare actual sales with the target each week, not just at month-end, so a shortfall is visible while you can still respond. Revisit how to calculate break even point whenever prices or costs change.
Break-even thinking also supports cash planning. Pair it with the routines in our article on how to improve cash flow management, since covering costs on paper and having cash on the right dates are related but separate challenges. For free business planning resources, see sba.gov.
If your target looks out of reach, the calculation shows your three honest levers: raise price carefully, reduce variable cost per sale, or lower fixed costs. Test one change at a time and recalculate, rather than hoping volume alone will fix a weak contribution.

Frequently Asked Questions
How often should I recalculate my break-even point?
Recalculate whenever prices or costs change, and review it at least quarterly. Rent rises, wage changes, and supplier prices all move the target, so an old figure can mislead your planning.
What if I sell many different products?
Use a weighted average price and variable cost based on your actual sales mix. If one product line dominates, you can also calculate a separate break-even figure for that line alone.
Does the break-even point include my own pay?
It should include any regular salary or drawings you need the business to cover, listed with fixed costs. Leaving your own pay out makes the target look easier than it really is.
Can break-even analysis help with a price decision?
Yes. Try the new price in the same five steps and compare the units needed. You will see clearly whether a lower price demands an unrealistic jump in sales to cover costs.
