Break-even is where total revenue first covers all costs. Enter your fixed costs, unit price, and variable cost per unit; the calculator returns the units and revenue needed — and refuses politely when the price cannot ever break even.
Formula & methodology
BE units = F ÷ (p − v), where p − v is the contribution margin each unit adds toward fixed costs. Units round up — you cannot sell a fraction of a unit. If p ≤ v no break-even exists at any volume; the tool says so instead of printing a huge number.
Worked example
Fixed 50,000, price 25, variable 15 → contribution 10/unit → 5,000 units = 125,000 revenue.
Limits
Assumes constant price and variable cost across volume; bulk discounts, capacity steps, and mixed products need a fuller model. Estimates, not financial advice.
