Understanding Break-Even Analysis

Break-even analysis is fundamental to business planning. It answers the critical question: 'How much do I need to sell to stop losing money?' The formula is simple: Break-Even Units = Fixed Costs ÷ (Selling Price - Variable Cost per Unit).

  • Contribution Margin — Price minus variable cost per unit.

Frequently Asked Questions

What is the break-even point?

The break-even point is the number of units you need to sell to cover all costs (fixed + variable). At this point, total revenue equals total costs — no profit, no loss.

What is contribution margin?

Contribution margin is the selling price minus the variable cost per unit. It represents how much each unit 'contributes' toward covering fixed costs and generating profit.

How do I use the profit checker?

Enter any number of units sold to instantly see whether you'd have a profit or loss at that sales volume, and by how much.
