Break-even Explained
Every entrepreneur should know their break-even point. It’s the sales level where your revenue finally covers your costs. Before this point you’re running at a loss, after it you start to build profit.
Break-even is not just a number. It’s a decision-making tool that helps you plan with confidence, test scenarios, and know exactly what it takes to keep the lights on.
The break-even formula, term by term
| Term | What it means |
|---|---|
| Fixed costs | Expenses like rent, salaries or insurance that don't change with sales |
| Variable costs | Costs per unit such as materials, packaging and shipping |
| Contribution margin | Sales price minus variable costs |
| Contribution margin ratio | Contribution margin divided by sales price |
| Break-even sales | Fixed costs divided by the contribution margin ratio |
The formula
The basic formula is:
Break-even Sales = Fixed Costs Ă· Contribution Margin Ratio
Where:
Fixed Costs are expenses like rent, salaries, or insurance that don’t change with sales.
Contribution Margin is Sales Price – Variable Costs.
Contribution Margin Ratio is Contribution Margin Ă· Sales Price.
A simple example
A small brand sells premium office chairs.
Sales Price per Unit: ÂŁ400
Variable Cost per Unit: ÂŁ220 (materials, packaging, shipping)
Contribution Margin per Unit: ÂŁ180
Contribution Margin Ratio: 45%
Fixed Costs: ÂŁ18,000 per month (rent, staff, overheads)
Break-even Sales = ÂŁ18,000 Ă· 0.45 = ÂŁ40,000
That means the business needs 100 sales per month just to cover costs. Sale number 101 is where profit begins.
