Frequently asked questions

What is the break-even formula?

Break-even units = Fixed costs ÷ (Price − Variable cost per unit). Price minus variable cost is the contribution per unit.

How do I include a profit target?

Units needed = (Fixed costs + Target profit) ÷ Contribution per unit.

What is the margin of safety?

How far expected sales can fall before you make a loss: (Expected sales − Break-even sales) ÷ Expected sales.

What is the break-even point?

It is the level of sales at which total revenue equals total costs, so there is neither profit nor loss.

What is contribution margin?

Selling price minus variable cost per unit. It is the amount each sale contributes towards fixed costs and then profit.

How is break-even revenue calculated?

Break-even revenue = Fixed costs ÷ Contribution margin ratio, where the ratio is contribution per unit ÷ selling price.
