About the Break-Even Calculator

The break-even point is the sales volume at which total revenue exactly equals total costs — the point where a business stops losing money and starts turning a profit on each additional unit.

Formula: Break-even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit)

The denominator is called the "contribution margin" — the amount each unit sold contributes toward covering fixed costs. Once fixed costs are covered, every additional unit sold is pure profit (before tax).
