Frequently asked questions
What is the break-even formula?
Break-even units = Fixed Costs / (Price − Variable Cost per Unit).
What is contribution margin?
The percentage of each sale that contributes to covering fixed costs: (Price − Variable Cost) / Price × 100.
What if variable cost exceeds price?
You cannot break even — each unit sold loses money. Reduce variable costs or increase price.
