Calculating your break-even (units) is straightforward once you know the Break-even formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Break-even Calculator.

What is Break-even?

The Break-even calculation tells you your break-even (units) from a few simple inputs. The figure you are solving for here is the break-even (units), expressed in units.

The Break-even formula

This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:

  • Fixed costs — a money amount. Example: ₹1,00,000.
  • Price per unit — a money amount. Example: ₹500.
  • Variable cost per unit — a money amount. Example: ₹300.

How to calculate it step by step

  • Write down the fixed costs (for example, ₹1,00,000).
  • Write down the price per unit (for example, ₹500).
  • Write down the variable cost per unit (for example, ₹300).
  • Apply the formula above to get your break-even (units).
  • Double-check the result with the Break-even Calculator.

Worked examples

Example 1

Input / OutputValue
Fixed costs₹1,00,000
Price per unit₹500
Variable cost per unit₹300
Break-even (units)500 units
Break-even revenue₹2,50,000
Contribution per unit₹200

With fixed costs of ₹1,00,000, price per unit of ₹500 and variable cost per unit of ₹300, the break-even (units) works out to 500 units.

Example 2

With fixed costs of ₹2,00,000, price per unit of ₹500 and variable cost per unit of ₹300, the break-even (units) works out to 1,000 units.

ResultValue
Break-even (units)1,000 units
Break-even revenue₹5,00,000
Contribution per unit₹200

Example 3

With fixed costs of ₹50,000, price per unit of ₹500 and variable cost per unit of ₹300, the break-even (units) works out to 250 units.

ResultValue
Break-even (units)250 units
Break-even revenue₹1,25,000
Contribution per unit₹200

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.

Prefer not to do the maths by hand? — the Break-even Calculator does it instantly, for free, with the formula and a worked example built in.
