Three tools in one: calculate gross and net profit from revenue and costs, work out total revenue from units sold, or find your break-even point. Built for entrepreneurs, small businesses and finance students.
Choose one of three modes using the tabs above the calculator. Profit mode takes your total revenue, total costs, tax rate and units sold to produce gross profit, net profit, profit margin and profit per unit. Revenue mode calculates total gross revenue from units sold, price per unit, discount percentage and cost per unit — ideal for sales forecasting. Break-Even mode tells you how many units you need to sell to cover all your fixed costs, given a selling price and variable cost per unit. Enter your numbers and click Calculate.
Gross Profit is revenue minus total costs — it tells you how much money the business made before tax. Net Profit deducts tax from gross profit to give the true bottom-line earnings. Profit Margin expresses net profit as a percentage of revenue — it is one of the most important metrics for comparing business performance over time or across competitors.
In Revenue mode, the Gross Revenue figure includes any discount reduction from the list price. The Gross Profit in this mode is revenue minus the cost of goods sold, reflecting the direct profitability of each unit at the given volume and price point.
In Break-Even mode, the Contribution Margin per unit is what each sale contributes toward paying off fixed costs. The break-even unit count is the minimum sales volume at which the business neither profits nor loses. Any sales above break-even are pure profit at the contribution margin rate.
The break-even formula denominator — Price minus Variable Cost — is the contribution margin per unit. It represents how much money each unit sale contributes toward covering the fixed overhead. This is one of the most actionable numbers in business planning: increase it by raising prices or cutting variable costs, and break-even comes sooner.
