The break-even formula, explained
Every unit you sell brings in money, and every unit costs you money to deliver. What is left over — price minus variable cost — is the contribution margin: the amount each sale "contributes" toward paying your fixed costs. Your break-even point is simply where the contributions exactly cover those fixed costs:
Break-even units = Fixed costs ÷ (Price − Variable cost)
Break-even revenue = Break-even units × Price
With $3,500 of monthly fixed costs, an $800 average client fee, and $200 of variable cost per client, each client contributes $600. You need 5.83 — call it 6 — clients per month to break even, roughly $4,800 of revenue. Client number 7 is the first one that starts generating real profit.
Using it as a freelancer or small studio
For service businesses a "unit" is one client or one project. Two things make this version of the calculation especially useful:
- Include your own minimum draw in fixed costs. Your rent, food, and savings target are the business's most non-negotiable fixed costs. A break-even that doesn't include paying yourself is a hobby's break-even.
- Use realistic average fees. If half your clients pay $500 and half pay $1,100, your average unit price is $800. Don't use your dream rate — use your actual trailing average.
What the target-profit number tells you
Break-even keeps the lights on; the target-profit figure answers the question that actually matters: how much do I need to sell to make this worth doing? Add your desired monthly profit on top of fixed costs and divide by the same contribution margin. If you need 11 clients a month to hit your target but you've never served more than 8, you have a pricing problem, not a marketing problem — revisit your hourly rate before spending on ads.
