How many sales a month do you need to break even?
Enter three numbers — your monthly fixed costs, your average price per sale, and the variable cost of each sale — and see the sales volume and revenue where you stop losing money and start covering costs. It’s plain arithmetic on your own figures, not advice: nothing is sent anywhere, and a Certified ProAdvisor can help you act on it.
Break-even is the point where your contribution margin (price minus variable cost per sale) covers your fixed costs. This tool does that one calculation on your own numbers: break-even sales per month and the revenue that implies. It’s a model of your inputs, not financial advice — and it runs entirely in your browser. If the assumptions need pressure-testing, a fractional CFO conversation is the next step.

Break-even, in five questions.
How do you calculate break-even?
Break-even sales = monthly fixed costs ÷ contribution margin per sale, where contribution margin = price per sale − variable cost per sale. Multiply break-even sales by price for break-even revenue. This calculator does that on your own numbers and rounds up to whole sales.
What is contribution margin?
The money each sale contributes toward fixed costs after covering its own variable cost — price minus variable cost per sale. If contribution margin is zero or negative, there is no break-even at any volume, because each additional sale loses money rather than helping cover fixed costs.
What counts as a fixed vs variable cost?
Fixed costs stay roughly the same regardless of sales — rent, salaries, software, insurance. Variable costs rise with each sale — materials, payment processing fees, shipping, per-unit labor. Getting this split right is what makes a break-even number meaningful.
Is this calculator financial advice?
No. It’s a model of the numbers you enter, run entirely in your browser. Real break-even analysis accounts for product mix, seasonality, and step costs. Use it as a fast sanity check, then book a free discovery call if you want a Certified ProAdvisor to build a proper model.
What if my break-even looks impossibly high?
That usually signals thin contribution margin — your price is too close to your variable cost — or fixed costs that are too high for the price point. Both are fixable, and both are exactly what a fractional CFO engagement works on: pricing, margin, and cost structure.

Book the discovery callHow break-even is calculated.
Break-even is the sales volume at which total revenue exactly covers total costs — the point where you stop losing money. The math has two steps. First, contribution margin per sale = price − variable cost per sale: the dollars each sale contributes toward fixed costs after covering its own variable cost. Second, break-even sales = fixed costs ÷ contribution margin, rounded up to whole sales. Multiply by price for break-even revenue.
If the contribution margin is zero or negative, there is no break-even at any volume — each sale loses money, so selling more makes the hole deeper. The tool says so plainly rather than printing a misleading number. That case usually means a price increase or a variable-cost cut, which is exactly the kind of thing a fractional CFO engagement models.
This is a single-product, steady-state model. Real businesses have product mixes, seasonality, and costs that step up at certain volumes. The calculator is a fast sanity check on your own figures — not a forecast, and not advice.
