Break-even

Same break-even math — units and dollars side by side.

Some people plan in units; others think in monthly sales dollars. Same formula either way: fixed costs ÷ contribution per unit.

You get both outputs here. Use it when a partner asks “how much revenue until we’re covering rent?” and you’d rather not rebuild the spreadsheet.

How it's calculated

Contribution is price minus variable cost. Divide fixed costs by contribution for units; multiply by price for break-even revenue. Same caveats as the units page: if contribution ≤ 0, volume won’t save you.

units = fixed ÷ (price − variable)
revenue = units × price
