Order a break-even workflow

Order a reliable contribution and break-even workflow.

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.

Arrange in the correct order

1. Recalculate when a key assumption changes
2. Divide fixed cost by contribution and round required units up
3. Subtract variable cost per unit from selling price
4. Separate fixed cost from variable cost per unit
5. Define the period, product, price, and included costs
