How to Calculate Your Break-Even Point (2026)
Most small business owners can tell you their monthly revenue off the top of their head. Far fewer can tell you the number that actually decides whether they make money: the break-even point. It is the exact level of sales where you stop losing money and start keeping it. Below that line, every hour you work is subsidizing your own costs. Above it, each sale is real profit. This guide shows you how to calculate your break-even point step by step, with a worked example, a plain-English look at fixed versus variable costs, and the three levers that move the line in your favor.
The short version
Your break-even point is fixed costs divided by contribution margin (price per sale minus variable cost per sale). It tells you the minimum you must sell to cover every cost before earning a dollar of profit. Sort your costs correctly, run the formula, and you will know your target number for the month. After that, the game is simply getting past it faster by capturing more of the leads and bookings you already have coming in.
What the break-even point actually means
The break-even point is the sales level where total revenue equals total cost. Your profit at that exact point is zero. It sounds like an accounting curiosity, but it is one of the most useful numbers you can know, because it turns a vague worry ("are we doing okay?") into a concrete target ("we need 84 sales this month to cover everything, and we are at 61").
Once you know it, a lot of decisions get easier. Whether you can afford a new hire, whether a price change is safe, whether a slow month is a real problem or just noise, all of it becomes a comparison against one clear line instead of a gut feeling.
Step 1: Separate your fixed and variable costs
This is the step people get wrong, and it quietly ruins the whole calculation. Every cost your business has falls into one of two buckets.
Fixed costs
These do not change with how much you sell. You pay them whether you have a record month or a dead one: rent or mortgage, insurance, salaried staff, software subscriptions, loan payments, and equipment leases. Add them all up for one month. That total is what your sales have to cover before profit begins.
Variable costs
These rise and fall with each sale: materials and ingredients, packaging, shipping, payment processing fees, and hourly labor tied directly to a job. What you want here is the variable cost of a single sale, not the monthly total, so you can compare it against the price of that same sale.
A quick gut check: if a cost would still show up on your bank statement in a month where you sold nothing, it is fixed. If it only appears because you made a sale, it is variable. Payment processing fees are the classic trip-up. They feel like overhead, but they only exist when a sale happens, so they belong in the variable bucket.
Step 2: Find your contribution margin
The contribution margin is the heart of the whole thing. It is what is left from one sale after you pay the variable cost of that sale, and it is the amount each sale "contributes" toward covering your fixed costs.
Contribution margin per sale = price per sale minus variable cost per sale.
If you sell a product for $50 and it costs you $20 in materials, packaging, and processing fees, your contribution margin is $30. Every sale puts $30 toward the pile of fixed costs you need to clear. The bigger this number, the fewer sales you need to break even.
Step 3: Run the break-even formula
Now you have both pieces. The formula is short:
Break-even point (in units) = total fixed costs divided by contribution margin per sale
To express it in dollars instead of units, multiply the break-even units by your price per sale. That gives you the revenue target for the month. Both versions describe the same line; one is in things sold, the other is in money earned.
A worked example, start to finish
Say you run a small candle business. Here is every number you need and exactly where it lands.
| Item | Bucket | Amount |
|---|---|---|
| Studio rent | Fixed (monthly) | $1,200 |
| Insurance and software | Fixed (monthly) | $300 |
| Price per candle | Revenue per sale | $25 |
| Wax, wick, jar, label | Variable (per sale) | $8 |
| Packaging and processing fee | Variable (per sale) | $2 |
| Break-even point | Result | 100 candles a month |
Walk it through. Fixed costs are $1,200 plus $300, which is $1,500 a month. Variable cost per candle is $8 plus $2, which is $10. Contribution margin is $25 minus $10, which is $15 per candle. Break-even is $1,500 divided by $15, which comes to 100 candles. In dollars, that is 100 times $25, or $2,500 in sales a month just to hit zero. Candle number 101 is the first one that actually pays you, and it pays you $15.
That single number reframes everything. A month with 90 sales is not "pretty good," it is a $150 loss. A month with 130 sales is not just "busy," it is $450 of real profit. You now know precisely where the line sits.
The three levers that lower your break-even point
Once you can see the line, the question becomes how to get above it with less effort. There are only three real levers, and it helps to know what each one does before you pull it.
Raise your price
The fastest lever. In the candle example, moving the price from $25 to $28 lifts the contribution margin from $15 to $18, and the break-even drops from 100 candles to about 84. A small, well-communicated price increase almost always beats scrambling for extra volume.
Cut variable cost per sale
Better supplier pricing, less wasteful packaging, or a lower processing fee all widen the margin on every single sale. Shaving $2 off the variable cost has the same effect as raising the price $2, and your customer never notices.
Reduce fixed overhead
Every dollar you trim from rent, unused subscriptions, or idle capacity lowers the pile you have to cover. Because fixed costs sit on top of the formula, cutting them moves the break-even line down directly.
Capture more of the demand you already have
The hidden fourth lever. Most businesses do not have a demand problem, they have a leak: a message that went unanswered, a lead that never got a follow-up, a booking that fell through. Plug those leaks and you get past break-even without spending a cent more on marketing. This is the exact gap an AI employee like Intellure is built to close.
Why every sale above break-even matters more than you think
Here is the part that surprises people. Below the break-even line, your contribution margin is spent covering fixed costs. Above it, those fixed costs are already paid, so the full contribution margin of each new sale drops almost straight to profit. In the candle example, that means every sale past number 100 is worth $15 of near-pure profit, not the thinner margin you feel like you are earning.
That is why a missed lead late in the month stings so much. It is not an average sale you lost, it is one of your most profitable ones. So the quiet leaks matter: the customer who messaged on Instagram at 9pm and got no reply, the quote you meant to follow up on and forgot, the appointment that never got confirmed. Each of those is a high-margin sale walking out the door. Intellure exists to catch exactly those: it answers every message the moment it lands, follows up on leads that go quiet, and books appointments around the clock, so more of your demand actually converts into the above-the-line sales that pay you the most.
Common mistakes to avoid
Miscategorizing costs
Putting a variable cost in the fixed bucket, or the reverse, is the number one error. Processing fees, shipping, and hourly job labor are variable, not overhead. When in doubt, ask whether the cost exists in a month with zero sales.
Forgetting your own pay
If you want a salary out of the business, include it as a fixed cost. A break-even that ignores paying yourself is a break-even that keeps you working for free, which is not really breaking even at all.
Using stale numbers
A rent hike, a new subscription, or a supplier price jump all move the line. Recalculate whenever a real cost changes, and at least once a quarter, so the target you are aiming at is the real one.
Treating it as one fixed answer
If you sell several products at different margins, run break-even on your average contribution margin, or on your main product. It is a planning tool, not a courtroom exhibit. A close, useful estimate beats a perfect number you never actually calculate.

The bottom line
The break-even point turns running a business from a feeling into a number. Sort your costs, find your contribution margin, divide, and you know the exact target you have to clear each month. Once the line is clear, the winning move is rarely to chase brand-new demand: it is to stop leaking the demand you already have. Every unanswered message and forgotten follow-up is a high-margin, above-the-line sale you were owed. Close those gaps and you cross break-even sooner, every month, with nothing extra spent to get there.
