How to Calculate Your Break-Even Point
Your break-even point is the amount you need to sell to cover your costs, with nothing left over and nothing missing. Below it you are making a loss; above it you start making a profit. It is one of the most useful numbers a small business can know, because it turns a vague worry (am I selling enough?) into a specific target you can aim at each month. This guide covers the formula, the fixed-versus-variable-cost split it depends on, how to work it out in both units sold and revenue, and worked examples for a product business and for a freelancer who sells time rather than things. It is general business information, not financial advice.
What the break-even point actually tells you
The break-even point is the level of sales at which your total revenue exactly equals your total costs. At that point you make neither a profit nor a loss. Sell one more and you are in profit; sell one fewer and you are covering costs out of your own pocket. It can be expressed two ways: as a number of units you need to sell, or as an amount of revenue you need to take in. Both describe the same moment, just in different currencies, so to speak.
The most important thing to understand is what break-even is not: it is not your goal. It is your floor. A business that only ever breaks even never pays its owner a real return and has no cushion for a slow month. The value of the number is that it tells you where survival ends and profit begins, so you can set a sales target above it, judge whether a price is viable, and see how much a quiet period would cost you before you start losing money.
Fixed costs vs variable costs (get this split right first)
The whole calculation rests on sorting your costs into two buckets, and this is where most people go wrong, so it is worth slowing down. Fixed costs are the ones you pay regardless of how much you sell: rent, software subscriptions, insurance, a phone contract, any salaries that do not change with sales. If you sold nothing this month, you would still owe them. Variable costs are the ones that rise with each sale: the materials or stock in the thing you sell, payment-processing fees, packaging, delivery, a commission per job. Sell twice as much and they roughly double.
The gap between your price and your variable cost per sale is the key figure, and it has a name: the contribution margin. It is what each sale contributes toward covering your fixed costs (and, once those are covered, toward profit). If you sell something for 25 and the variable cost of that sale is 10, each sale contributes 15. Break-even is simply the point where enough of those 15s have stacked up to cover all your fixed costs. Hold that idea and the formula writes itself.
The break-even formula
In units, the formula is: break-even point (units) = fixed costs divided by (price per unit minus variable cost per unit). The bracket at the bottom is just the contribution margin per unit, so another way to say it is fixed costs divided by contribution margin per unit.
If you would rather know the revenue you need rather than a unit count, use the contribution-margin ratio (contribution margin divided by price): break-even revenue = fixed costs divided by the contribution-margin ratio. This version is handy when you sell lots of different items at different prices and counting units makes no sense, because it works off your overall margin instead.
A quick note on rounding: if the units formula gives you 133.3, round up to 134, never down. You cannot sell a third of an item, and rounding down would leave you just short of covering your costs.
A worked example (a small product business)
Say you run a small business with fixed costs of 2,000 a month (rent, software, insurance). You sell an item for 25, and the variable cost of each one (materials, packaging, the card fee) is 10. Your contribution margin per sale is 25 minus 10 = 15.
Break-even in units is 2,000 divided by 15 = 133.3, which rounds up to 134 units a month. In revenue, your contribution-margin ratio is 15 divided by 25 = 0.6, so break-even revenue is 2,000 divided by 0.6 = about 3,333 a month. (Selling the rounded-up 134 units brings in 3,350, which is 17 over the exact figure, the small buffer that rounding up gives you.) Either way, that is the line: below roughly 3,333 in sales you are losing money that month, above it you are in profit. Now you have a concrete monthly target instead of a vague hope.
Break-even for a freelancer or service business
If you sell your time rather than physical products, the same logic works but the inputs look different, and this is the version most online break-even guides skip. Your variable cost per job is often small (maybe some software or a subcontractor), so the main thing your billable work has to cover is your fixed overheads plus the pay you actually need to take home. A fair way to set it up is to treat the wage you want to pay yourself as a cost the business must cover, then divide by your rate.
Worked example: your business overheads are 500 a month, and you need to pay yourself 3,000 a month to live. So your work has to bring in 3,500 a month before you are truly in the clear. (That 3,000 is your take-home pay, so if tax comes out of it, set the figure a little higher.) At a billable rate of 50 an hour with negligible per-job costs, that is 3,500 divided by 50 = 70 billable hours a month, roughly 16 or 17 a week. The catch worth knowing in advance: billable hours are not the same as working hours. Admin, quoting, chasing payment and marketing are all unpaid, so hitting 70 billable hours usually means a considerably longer working week, which is exactly why your rate has to account for it. Our guide to how much to charge walks through setting that rate from the take-home you need.
What to do with your break-even point
Once you have the number, it earns its keep in a few ways. Set your monthly sales target above it with a deliberate margin, so a normal month leaves a real profit and a slow one does not sink you (the gap between your expected sales and your break-even is your margin of safety). Use it to sanity-check a price: if breaking even needs more sales than you could realistically make, the price is too low or the costs too high, not the market's fault. And test changes against it. Because a higher price widens the contribution margin, even a modest price rise can pull your break-even point down sharply, which is often a faster lever than cutting costs.
Break-even also connects to cash. Covering costs on paper is not the same as having the money in the bank on the day a bill is due, especially if customers pay late, so it is worth pairing your break-even target with a simple cash flow forecast. In practice the way you track whether you are clearing break-even is your own sales records: with Remit you can send clear invoices and keep a running statement of account per client, so the revenue side of the calculation is something you can actually see rather than guess. To run the numbers quickly, the free break-even calculator works out the units for you from your fixed costs, price and cost per unit.
The short version
Split your costs into fixed and variable, work out your contribution margin (price minus variable cost per sale), and divide your fixed costs by it to get the units you need to break even, or divide by your contribution-margin ratio to get the revenue. Round units up, never down.
Then treat the result as a floor, not a target: set your real goal above it, keep a margin of safety, and remember that raising your price lowers your break-even point faster than most cost-cutting will. This is general business information and not financial advice, so for decisions specific to your business speak to an accountant.
