▸ METHODOLOGY
Units to break even = Fixed ÷ (Price − Variable). Contribution margin is the per-unit dollar flow into fixed-cost recovery. Above break-even, every unit contributes pure profit; below, every unit widens the loss.

How to use

  1. Enter total fixed costs (rent, salaries, etc).
  2. Enter the price you sell each unit for.
  3. Enter the variable cost per unit (materials, shipping).
  4. Break-even quantity = fixed costs ÷ (price − variable cost).

Examples

$5,000 fixed, $25 price, $10 variable
334 units to break even — $8,350 in revenue.
$20,000 fixed, $100 price, $40 variable
334 units to break even — $33,400 in revenue.

Before you trust the result

Check the inputs that matter most: dates, rates, units, costs, and any optional fields you skipped. A calculator can only work with the numbers entered here, so use the result as a decision check rather than a final answer when money, health, tax, legal, or safety consequences are involved.

If the result feels surprising, change one input at a time and watch which number moves. That usually shows the real lever behind the decision.

Frequently asked questions

› What counts as fixed vs variable cost? Comparison

Fixed costs stay the same no matter how many you sell (rent, salaries). Variable costs scale per unit (materials, per-order shipping).

› Does this include taxes?

No — this is the pre-tax contribution model. Tax shrinks your effective margin; reduce price or increase variable cost accordingly.
