Break-Even Point Calculator

Units & Revenue to Break Even • Profit Targets • Margin of Safety

This assumes a single product (or a consistent average price and cost across your product mix) and constant fixed costs over the period — real businesses often sell multiple products with different margins, which this simple version doesn't separate out.
Your Cost Structure

About This Calculator

The break-even point is the sales volume where total revenue exactly equals total cost — no profit, no loss. This tool works it out in both units and dollars from your fixed costs, variable cost per unit, and selling price. Beyond the basic break-even, you can enter a profit target to see exactly how many units and how much revenue would get you there, or enter your expected or actual sales volume to see your margin of safety — how much sales could drop before you'd fall back to break-even.
