Break-Even Calculator

Free

The sales revenue you need to cover every cost — fixed and variable.

What is the Break-Even Calculator?

Break-even is the revenue level at which your total profit is exactly zero — every euro coming in is matched by a euro of cost. Anything above break-even is real profit; anything below is loss you're absorbing from cash reserves.

Knowing the number gives you a hard floor for sales targets, a reality check when a price feels too low, and a clear answer to 'how much business do I need to stay open?'

When to use it

  • Setting an annual or monthly sales target.
  • Deciding whether a new contract will actually move the needle.
  • After your fixed costs change (a new lease, a hire, a software subscription).
  • Before lowering prices — you'll see how many more sales the discount demands.

The formula

Break-even sales = fixed costs ÷ gross margin. If your fixed costs are €15,000 per month and you make 40 cents on every euro of sales, you need €37,500 of sales just to break even. The gross margin already accounts for variable costs (materials, labour) — fixed costs are everything that bills regardless of sales.

Worked example

Monthly fixed costs
€15,000
Gross margin
40%
Result

€37,500 in monthly sales to break even

At a 40% gross margin, every €1 of sales contributes 40c towards fixed costs. €15,000 ÷ 0.40 = €37,500. Below that, the business loses money; above it, profit kicks in at 40c per extra €1 of sales.

How to use it

  1. 1

    Enter your fixed costs per month (or per year — whichever you think in)

  2. 2

    Enter your gross margin percentage

    If you don't know it, use the Profit Margin Calculator to work it out from a sample sale.

  3. 3

    Read the break-even sales figure

  4. 4

    Compare to your actual sales — anything above is profit, anything below is loss

  5. 5

    Save the scenario; redo it whenever fixed costs or margin change

Common questions

What counts as a fixed cost vs variable cost?+

Fixed costs are paid regardless of sales volume: rent, salaries, software subscriptions, insurance. Variable costs scale with sales: materials, sales commission, packaging, payment processing fees. Variable costs come out of gross margin; fixed costs are what gross margin has to cover.

What's the difference between break-even sales and break-even units?+

Break-even sales is a revenue number. Break-even units is the number of products or jobs you need to sell. Units = fixed costs ÷ contribution per unit. The sales version is easier when your prices vary (services, project work).

Should I aim to operate at break-even?+

No — break-even is the floor, not the goal. Aim well above it so you have a buffer for cost increases, slow months, and reinvestment. A common rule of thumb is to target sales at least 50% above break-even.
