Breakeven Calculator

Calculate the breakeven point — the units and revenue where total costs equal total revenue, and profit becomes zero. Enter fixed costs, selling price and variable cost per unit to see how many sales you need before you start making money.

What this means

Each sale contributes its price minus variable cost toward fixed costs. The breakeven point is when those contributions have fully covered the fixed costs. After that, each unit sold is pure contribution margin.

How we calculate it

Formula

Breakeven units = Fixed costs ÷ (Price − Variable cost per unit). Breakeven revenue = Units × Price.

Worked example

Fixed $10,000, price $50, variable cost $30:

  1. 1Contribution per unit = 50 − 30 = $20
  2. 2Units = 10,000 ÷ 20 = 500
  3. 3Revenue = 500 × 50 = $25,000

Important assumptions

  • Price and variable cost are assumed constant across all units.

Frequently asked questions

What are fixed and variable costs?

Fixed costs stay constant regardless of sales (rent, salaries). Variable costs scale with production (materials, shipping).

Why is breakeven important?

It tells you the minimum sales needed to avoid losses and lets you price with confidence — essential for launching a product or a campaign.
