Break-Even Calculator

The break-even point is where revenue equals total costs. This is the essential number for any product launch or business plan.

How It Works

Calculates contribution margin (price − variable cost per unit), then divides fixed costs by it to find break-even quantity and revenue.

Formula

Contribution Margin = Price − Variable Cost
Break-Even Units = Fixed Costs ÷ CM
Break-Even Revenue = Units × Price

Example

Fixed costs $10,000/month, price $50, variable cost $20:
CM=$30. Break-even: 334 units = $16,700 revenue.

When to Use This Calculator

Use before any product launch to understand minimum required sales, and to test how pricing or cost changes affect your break-even.

Common Mistakes to Avoid

  • Misclassifying fixed vs variable costs — classify carefully.
  • Treating break-even as the target — zero profit; actual target should be above it.
  • Not updating as costs change — break-even shifts every time costs change.
