Calculate break-even units

Fixed cost is 12,000. Price is 50 per unit and variable cost is 30. How many units are needed to break even?

Growth and break-even model

Apply change to updated balances and contribution to fixed cost

Compound balance
Start × (1 + rate)^periods
Contribution
Price − variable cost per unit
Break-even
Fixed cost ÷ contribution per unit
Unit rule
Round required whole units up
Sensitivity
Recalculate after a changed assumption

Period assumptions drive growth, while price and variable cost drive contribution. Sensitivity checks show how modeled results change without turning them into guarantees.
