Break-Even Calculator

What break-even really tells you

Your break-even point is the moment a venture stops costing you money and starts earning it: the number of sales where revenue finally covers every cost, leaving zero. One sale past it, you are in profit. One short, you are funding the difference yourself. It sounds basic, but many small operations never put a hard number on it, which means they are flying without one of the most useful figures in the business.

The idea behind the number: contribution

The whole calculation hinges on contribution. Every sale brings in a price, and every sale costs something to deliver. What is left over contributes toward your fixed costs. Charge $1,500 for a project that costs you $300 in subcontracting and fees, and each project contributes $1,200. Stack up enough of those $1,200 contributions to cover your fixed overhead, and you have broken even.

• Contribution per sale = price - variable cost
• Break-even sales = fixed costs / contribution per sale
• Break-even revenue = fixed costs / contribution-margin ratio

A worked example

Imagine your fixed costs are $3,000 a month: software, a co-working desk and the baseline pay you need to live. You charge $1,500 a project, and each project costs about $300 to deliver. Each one contributes $1,200, so you break even at $3,000 / $1,200 = 2.5 projects. The exact break-even revenue is $3,750, but projects do not usually arrive in half-units, so you round up to 3 projects and expect $4,500 of billings. Want to clear $4,000 of profit on top? Now you need ($3,000 + $4,000) / $1,200 = 5.83, so 6 projects and $9,000 of rounded-sales revenue.

How freelancers should read this

The textbook version of break-even is written for factories, but it maps cleanly onto solo work once you translate the words. Your fixed costs are not just software; the biggest one is usually the income you need to draw to live, so include it. Your price is your typical project value or hourly rate. Your variable cost is whatever you pay out per job: subcontractors, stock photography, payment fees, materials.

Pure-service freelancers often have a near-zero variable cost, which makes almost the whole price contribution. In that case, the break-even point lands on how many billable hours cover your overhead. If you have not set that rate deliberately yet, start with the hourly rate calculator, then use the margin and markup calculator to check the contribution on a single job.

Margin of safety: the question after break-even

Once you know your break-even, the useful follow-up is how much cushion you have above it. If you break even at 3 projects and you are booking 5, two of those projects are your margin of safety: the room you would lose before slipping back into the red. A break-even number sitting uncomfortably close to your actual volume is an early warning worth acting on before the slow season, not during it.

Assumptions and limitations

• Costs are split cleanly into fixed and variable. Reality is messier. Some costs are stepped; re-run the numbers when a step changes.
• One average price and cost. If you sell a mix at different prices, use a sensible average or run the calculator separately for each line.
• Same period throughout. Keep fixed costs, price and the profit target on the same clock.
• Pre-tax. The profit target is before income and self-employment tax. To plan the tax on top, see the self-employment tax calculator.
