Break-even
How much revenue until fixed costs stop eating the week?
Partners and landlords talk in dollars. This turns fixed costs, price, and variable cost into the sales total that covers the month — same math as units break-even, dollars first.
If contribution per unit is zero or negative, no sales volume fixes it. Raise price or cut variable cost before chasing more traffic.

How it's calculated
Contribution is price minus variable cost. Divide fixed costs by contribution for units; multiply by price for break-even sales dollars.
units = fixed ÷ (price − variable) sales = units × price
