Key Features

Break-even units and revenue
Calculates both the unit volume and the total sales revenue needed to cover all fixed and variable costs — the two most commonly needed figures in business planning.
Contribution margin
Displays the contribution margin per unit (selling price minus variable cost), the key driver of the break-even calculation, with a plain-English explanation.
Profit / loss at expected volume
If you enter expected units, the tool shows how much profit or loss you would make at that sales volume, helping validate business plans and pricing decisions.
Revenue vs cost chart
A visual chart plots the revenue line and total cost line against unit volume. The break-even point is marked with a vertical line, and the expected units line is overlaid if provided.
