Break-Even Point Calculator

(Units, Revenue & Contribution Margin Tool)

Calculate exactly how many units you need to sell — and how much revenue that represents — before your business starts turning a profit, plus what it takes to hit a specific profit target.

Step 1 — Fixed & Variable Costs

Rent, salaries, insurance — costs that don't change with sales volume

What you charge the customer per unit

Materials, packaging, commission — cost that scales with each sale

Calculated Results

Enter fixed costs, price, and variable cost to calculate your break-even point.

What the Break-Even Point Actually Measures

The break-even point is the sales volume at which total revenue exactly equals total costs — the line between losing money and making it. Below that number of units, fixed costs like rent and salaries haven't been fully covered yet; above it, every additional unit sold drops straight to profit at your contribution margin rate.

Break-Even Units = Fixed Costs ÷ (Price − Variable Cost per Unit)

The denominator here — price minus variable cost — is called the contribution margin. It's the leftover per unit after direct costs, and it's the number that pays down your fixed costs one sale at a time.

Worked Example

A small workshop has $5,000/month in fixed costs (rent + one salaried employee). Each product sells for $25 and costs $10 in materials and packaging to make.

  • Contribution margin: $25 − $10 = $15 per unit
  • Break-even units: $5,000 ÷ $15 = 334 units/month
  • Break-even revenue: 334 × $25 = $8,350/month

Selling unit #335 and beyond in that month is where actual profit begins — each one adds $15 straight to the bottom line, since fixed costs are already fully covered.

Frequently Asked Questions (FAQ)

Yes, on paper — a lower price shrinks your contribution margin, so you need more units to cover the same fixed costs. Whether it's still a good move depends on whether the lower price sells enough additional volume to more than make up the difference, which this calculator won't tell you on its own.

Then your contribution margin is negative, and there is no break-even point — every unit sold loses more money, and selling more only makes the loss bigger. The price needs to increase or the variable cost needs to come down before break-even math applies at all.
