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 / Output | Value |
|---|---|
| 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.
| Result | Value |
|---|---|
| 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.
| Result | Value |
|---|---|
| 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.
