Frequently Asked Questions
Everything you need to know about the Break-Even Calculator.
How does the break-even calculator work?
Enter fixed costs, variable cost per unit, and selling price; it computes the number of units and revenue needed to cover all costs.
Is it free?
Completely free, no sign-up or limits.
What is contribution margin?
The amount each unit sold contributes toward covering fixed costs, after variable costs are subtracted from the selling price.
What if my selling price is lower than my variable cost?
The calculator detects this and explains that break-even is impossible at those numbers, rather than showing an error or infinity.
Can I calculate units needed for a target profit, not just break-even?
Yes, enter a target profit and the calculator adds it to the break-even formula.
Does it show a chart?
Yes, a chart plots total cost and total revenue across a range of unit volumes with the break-even point marked.
What's the difference between break-even units and break-even revenue?
Units is how many items you need to sell; revenue is the sales figure equivalent to that.
Can I use it for a service business, not just physical products?
Yes, units can represent hours, sessions, or any billable unit.
