How we work it out

Textbook management accounting, not a benchmarked score — everything's asked in dollars, not "units," so it works whether you sell products or services. Here's what happens:

  1. Your fixed costs

    What you pay every month regardless of how much you sell — rent, salaries, insurance.

  2. Your variable costs

    What scales with sales — materials, supplies, commissions — at your current sales level.

  3. Your current sales

    What you're actually bringing in each month right now.

  4. Your margin of safety

    How far your current sales sit above (or below) the break-even point — 20%+ is comfortable, under 0% means you're currently losing money.

Question 1 of 4

Costs that stay the same regardless of how much you sell — rent, salaries, insurance, subscriptions.

Costs that go up when you sell more and down when you sell less — materials, product, supplies, sales commissions. Not rent or salaries, which stay the same either way.

What you're actually bringing in each month right now.

Are these numbers from your real books, or a rough estimate?

Estimated numbers can still get a useful result — it just won't be shown as fully healthy (green), since we can't be that confident in a guess.

Your Profit Lights

This calculator provides an educational estimate only and does not provide certified financial, accounting, or business advice. It assumes costs behave the same at different sales levels, which isn't always true in the real world. Actual break-even depends on more than three numbers.
