About

How many units do you need to sell each month to cover your fixed costs? Enter fixed costs, price, and variable cost per unit — we compute the break-even quantity and revenue.

How it works

  1. 01Contribution margin per unit = price − variable cost.
  2. 02Break-even units = fixed costs / contribution margin.
  3. 03Break-even revenue = break-even units × price.

Examples

SaaS subscription

$50k/mo fixed costs, $99 price, $20 variable (hosting, support). Contribution = $79. Break-even ≈ 633 customers.

Hardware product

$100k fixed, $200 price, $140 cost-of-goods. Contribution = $60. Need 1,667 units to break even — and that's before marketing payback.

FAQ

What counts as fixed?+
Costs that don't change with volume: salaries, office, base software stack. NOT cost of goods, payment fees, or per-customer support.
Does this account for time to acquire customers?+
No — it's a steady-state calculation. Combine with the Runway calculator to see when you actually hit break-even.
