Frequently asked questions
How do you calculate break-even?

What is contribution margin?
Price per unit − variable cost per unit — what each sale contributes to covering fixed costs, then profit.
What does break-even tell me?
The sales volume where revenue exactly covers all costs — no profit, no loss. Beyond it is profit.
