How it works
The break-even point is the number of units you need to sell so that total revenue equals total costs — meaning zero profit and zero loss. Each unit sold above break-even contributes pure profit. The contribution margin per unit is the selling price minus the variable cost; it represents how much each sale contributes toward covering fixed costs and then generating profit.
Fixed costs vs variable costs
Fixed Costs
Costs that remain constant regardless of production volume, such as rent, salaries, insurance, and equipment depreciation.
Variable Costs
Costs that change directly with the number of units produced, such as raw materials, packaging, direct labour, and shipping per unit.
Frequently Asked Questions
What is the break-even point?
The break-even point is the level of sales at which total revenue equals total costs — resulting in zero profit or loss. Every unit sold above this level generates profit equal to the contribution margin per unit. It is a fundamental tool for pricing decisions, capacity planning, and evaluating business viability.
What is contribution margin?
Contribution margin = Selling Price per Unit − Variable Cost per Unit. It represents how much each sale contributes to covering fixed costs and generating profit. A higher contribution margin means you reach break-even faster and keep more profit per unit above that point.
How can I reduce my break-even point?
You can reduce the break-even point by: (1) Increasing selling price (if the market allows), (2) Reducing variable costs (renegotiating supplier contracts, improving efficiency), (3) Reducing fixed costs (lower rent, fewer overheads), or (4) Shifting fixed costs to variable costs (e.g., outsourcing instead of hiring). A lower break-even means reaching profitability with fewer sales.
Can the break-even analysis work for service businesses?
Yes. For services, replace 'units' with 'clients', 'service engagements', or 'billable hours'. Fixed costs include rent, salaries, and software subscriptions. Variable costs include direct service delivery costs, commissions, and materials. The contribution margin becomes (fee per client − direct cost per client).
What is margin of safety?
Margin of safety = Actual Sales − Break-even Sales. It shows how much sales can fall before you start making a loss. A higher margin of safety means your business is further from the break-even point — lower risk of loss if sales decline. Expressing it as a percentage of actual sales (Margin of Safety %) is useful for comparison.
