Break-even Revenue Calculator
Revenue or units needed to cover all fixed and variable costs.
Break-even is the point where total revenue equals total costs—no profit, no loss. Fixed costs (rent, salaries, software) don't change with volume; variable costs (materials, shipping, fees) do. The formula: Break-even units = Fixed costs ÷ (Price − Variable cost per unit). This calculator helps you see how many units or how much revenue you need to cover costs, and how changes in price or costs affect that number.

The Revenue Number Your Business Can’t Afford to Fall Below
Break-even revenue is the minimum your business needs to generate each month to cover all costs — fixed and variable — with zero profit or loss. Knowing it precisely changes how you think about sales targets, hiring decisions, and risk. It’s the floor below which every day of operation costs you money. This calculator helps you build it from your actual cost structure.
It’s most useful when you’re setting monthly revenue goals, evaluating whether a slower month is an emergency or just noise, or deciding whether you can afford a new hire or expense before the revenue to justify it has materialized. Every business decision looks different when you know exactly what revenue number the business needs to stay healthy.
