Accounting Guide
The break-even point is the sales level where total revenue covers total costs, so the business has no profit and no loss yet.
Quick answer
Break-even point is where revenue equals total costs.
At break-even, the business has covered costs but has not made profit yet.
Sales above break-even can start creating profit.
Sales below break-even usually mean the business is not covering all costs.
Formula
Contribution Margin per Unit = Selling Price per Unit - Variable Cost per Unit
Break-even Units = Fixed Costs / Contribution Margin per Unit
Break-even Sales = Break-even Units x Selling Price per Unit
Terms
Fixed costs stay the same within the activity range, variable costs change with each unit sold, and contribution margin is the amount each unit contributes toward fixed costs and then profit.
| Term | Meaning | Simple example |
|---|---|---|
| Fixed Costs | Costs that stay the same over the relevant activity range | Rent, basic salaries, insurance |
| Variable Costs | Costs that change with each unit sold | Materials, packaging, direct commission |
| Selling Price per Unit | Amount charged for one unit | RM 50 per unit |
| Contribution Margin per Unit | Selling price minus variable cost per unit | RM 50 - RM 30 = RM 20 |
| Break-even Units | Units needed to cover fixed costs | 500 units |
| Break-even Sales | Sales revenue needed to cover fixed costs | RM 25,000 |
Steps
Worked example
A small business has fixed costs of RM 10,000. It sells a product for RM 50 per unit. The variable cost is RM 30 per unit.
| Item | Amount |
|---|---|
| Fixed costs | RM 10,000 |
| Selling price per unit | RM 50 |
| Variable cost per unit | RM 30 |
| Contribution margin per unit | RM 20 |
| Break-even units | 500 units |
| Break-even sales | RM 25,000 |
Contribution margin is RM 50 - RM 30 = RM 20.
Break-even units are RM 10,000 / RM 20 = 500 units.
Break-even sales are 500 x RM 50 = RM 25,000.
The business needs to sell 500 units before it begins earning profit, assuming the inputs stay the same.
Targets
Break-even units tell you how many units must be sold. Break-even sales tell you the sales revenue needed. Units are useful for product planning, while sales amount is useful for revenue targets.
| Measure | Formula | Best for |
|---|---|---|
| Break-even Units | Fixed Costs / Contribution Margin per Unit | Unit sales targets |
| Break-even Sales | Break-even Units x Selling Price per Unit | Revenue targets |
Why it matters
Input changes
Higher fixed costs usually increase break-even point.
Higher variable cost per unit lowers contribution margin and increases break-even point.
Higher selling price can lower break-even point if variable cost stays the same. Lower selling price can increase break-even point.
Cost or price changes should be checked again.
| Change | Likely effect on break-even point |
|---|---|
| Fixed costs increase | Break-even point increases |
| Variable cost per unit increases | Break-even point increases |
| Selling price increases | Break-even point decreases |
| Selling price decreases | Break-even point increases |
| Contribution margin increases | Break-even point decreases |
Limitations
It is a simplified planning tool.

FAQ
Break-even point is the sales level where total revenue covers total costs, with no profit and no loss.
Break-even units equal fixed costs divided by contribution margin per unit. Break-even sales equal break-even units multiplied by selling price per unit.
Calculate contribution margin per unit, then divide fixed costs by that contribution margin.
Multiply break-even units by the selling price per unit.
Contribution margin is selling price per unit minus variable cost per unit. It shows how much each unit contributes toward fixed costs and then profit.
No. Break-even means revenue covers costs. Profit starts after sales move above the break-even point.
If fixed costs increase and other inputs stay the same, the break-even point usually increases.
If variable cost per unit increases, contribution margin falls and the break-even point usually increases.
Yes. It can help check simple break-even units, break-even sales, and contribution margin calculations.
No. Break-even analysis is a useful planning check, but it does not replace demand research, cash flow review, or professional advice.
