ToolNestFree Break-Even Calculator
Last updated: October 21, 2026
Quick answer: Every business has a line in the sand: the sales level where revenue finally covers costs and the next sale starts making money. This free break-even calculator finds that line. Enter your fixed costs (rent, salaries, software — the bills that arrive whether you sell anything or not), your price per unit, and your variable cost per unit (materials, packaging, commission — the cost of each sale), and it returns your break-even units, break-even revenue, contribution margin, and margin of safety at your current sales — plus how many units you need to hit a target profit. The math is one division (fixed costs ÷ contribution margin), but the decisions it informs — pricing, hiring, whether a product is viable at all — are the biggest ones a small business makes. Everything runs in your browser; no signup, nothing uploaded.
Assumptions, stated plainly: one product, one price, constant variable cost per unit, and fixed costs that truly don't move with volume. Break-even here is operating break-even (before tax); loan repayments are not fixed costs in this math unless you add them deliberately — see the FAQ on cash break-even. A planning estimate, not financial advice.

How to Use the Break-Even Calculator
- Enter your fixed costs per month: rent, salaries, insurance, software subscriptions — everything you'd pay even if you sold zero units.
- Enter your selling price per unit and your variable cost per unit (materials, packaging, per-sale commission, payment fees). The difference is your contribution margin — the amount each sale contributes toward fixed costs.
- Click Calculate break-even. Read break-even units (fixed costs ÷ contribution margin, rounded up — you can't sell a fraction of a unit) and break-even revenue (those units × price).
- Optionally add your current monthly units to see profit or loss at today's sales and your margin of safety — how far sales can fall before you start losing money.
- Optionally add a target monthly profit to see the units that profit requires: (fixed costs + target profit) ÷ contribution margin. That number is your real sales goal, not the break-even number.
Why Use Our Break-Even Calculator?
- Break-even units and revenue — the two headline numbers, with the contribution margin and margin ratio shown so you can verify the math.
- Profit or loss at current sales — add your actual monthly units and see where you stand today, not just where the line is.
- Margin of safety — the percentage sales can drop before losses start, the single most useful risk number on the page.
- Target-profit units — break-even is survival; the target-profit figure turns the same math into a sales goal.
- Impossible-case guard — if price is at or below variable cost, the calculator says plainly that you never break even, instead of returning a nonsense negative number.
- 100% client-side — your costs and prices never leave your browser; no signup, no account.
Common Use Cases
- Pricing a new product: Before launch, run the price you're considering against realistic costs. If break-even needs 2,000 units a month and your channel reaches 300 buyers, the price — or the product — is wrong, and you learn it before spending on inventory.
- Etsy and online sellers: A handmade seller with $800/month in fixed costs (shop fees, tools, studio share) selling at $40 with $18 variable cost breaks even at 37 items — a concrete monthly target instead of a vague 'sell more' goal.
- Restaurant and café menu items: A dish priced at $16 with $5.50 in ingredients and packaging has a $10.50 margin; against $12,000 in monthly fixed costs it needs 1,143 covers to break even — the number that tells you whether the dish earns its menu slot.
- Freelancers: minimum viable month: Treat projects as units: $3,000 in monthly overhead (rent share, software, insurance) divided by $1,200 profit per project means 3 projects a month is survival — the fourth project is where the month turns profitable. Pair with our freelance rate calculator to set the project price itself.
- SaaS pricing sanity check: A SaaS founder with $25,000/month in fixed costs and $49 pricing against $9 per-user variable cost (hosting, support, fees) breaks even at 625 paying users — the milestone to compare against churn: our churn calculator shows how many new users that milestone actually demands each month.
Break-Even Calculator vs Alternatives
- A spreadsheet you build yourself: The most flexible option — multi-product weighting, scenarios, charts, all yours. The cost is the build: most founders' break-even spreadsheet is a half-finished tab from a funding round ago, and its formulas are rarely re-checked. Use this calculator for the fast answer; keep the spreadsheet for the full model.
- Ad-heavy calculator sites: The big generic calculator pages give you units and revenue and stop — no margin of safety, no target-profit units, no profit-at-current-sales, and a page full of ads around a one-division formula. This page answers the follow-up questions the formula alone doesn't.
- Your accountant or CFO: The most accurate answer, built on your real books — and the slowest and most expensive for a what-if. Ask them to validate the numbers you take to a lender; use this calculator to explore the what-ifs (price changes, cost cuts) before you pay for the meeting.
- Pricing by gut feel: The default for most small businesses: pick a price that 'feels right' and hope volume covers costs. Sometimes it works; when it doesn't, the business discovers its break-even point from its bank balance. Thirty seconds here replaces the guess with a number.
Bottom line: break-even math is one division, but founders who know their number price differently, hire differently, and spot trouble months earlier than founders who don't. This calculator gives you that number — plus the margin of safety and target-profit figures that turn it from trivia into a plan — for free, in your browser, with your numbers staying yours.
Frequently Asked Questions
What is the break-even point formula?
Break-even units = fixed costs ÷ (price − variable cost per unit), and break-even revenue = break-even units × price. The bracketed term is the contribution margin — what each sale leaves after its own costs to pay down fixed costs. Worked example: $10,000 fixed costs, $50 price, $30 variable cost → $20 margin → 500 units → $25,000 revenue. Sell 501 units and the 501st sale's $20 margin is your first profit.
What counts as a fixed cost vs a variable cost?
Fixed costs don't change with volume: rent, salaried staff, insurance, software subscriptions, loan interest. Variable costs scale with every sale: raw materials, packaging, shipping, sales commission, payment-processing fees. The tricky middle: hourly contractors and overtime behave like variable costs, and a step cost (a second warehouse, a new hire) is fixed until you cross a threshold — then it jumps. For this calculator, put step costs in fixed costs at the level your current volume actually incurs.
What if my price is lower than my variable cost?
Then you never break even — every sale loses money, so more sales mean more losses, not fewer. The calculator flags this instead of printing a negative break-even. The only fixes are raising the price, cutting the variable cost, or both; volume cannot save a negative margin. (Loss-leader pricing is the deliberate exception — and it only works if the loss-making sale reliably pulls a profitable one behind it.)
Can I use this for multiple products?
Directly, no — this is a single-product calculator. For a multi-product business, use a weighted-average contribution margin: multiply each product's margin by its share of sales, sum them, and divide fixed costs by that average. The result is break-even in blended units. For the cleanest picture, run your highest-volume product here first, then weight the rest in a spreadsheet — and revisit whenever the product mix shifts, because the average moves with it.
Does break-even include taxes and loan repayments?
No — this is operating break-even, profit before tax. Taxes come after profit, so they don't change the break-even point itself (they change what you keep beyond it). Loan interest is a fixed cost and belongs in the calculator; loan principal repayments are cash outflows, not costs — if you want a cash break-even (the sales level that covers all cash leaving the business), add monthly principal repayments to your fixed costs and label the result honestly as cash break-even.
How do I lower my break-even point?
Three levers, in order of power. Raise price: at $10,000 fixed and $30 variable cost, moving price from $50 to $55 lifts margin from $20 to $25 and cuts break-even from 500 to 400 units — a 10% price rise buys a 20% lower hurdle. Cut variable costs: negotiate materials, buy in bulk, or rework packaging; every dollar saved is a dollar of margin on every future sale. Cut fixed costs: renegotiate rent, cancel unused subscriptions, delay hires. Price is usually the highest-leverage lever — and the one founders touch last, because it feels risky. The calculator lets you test all three in seconds.
