Break Even Calculator

The Break-Even Calculator determines the exact point where your total revenue equals total costs — meaning zero profit and zero loss. It tells you how many units you need to sell or how much revenue you need to cover all fixed and variable expenses, helping you make informed business decisions.

How the Formula Works

Break-Even Units = Fixed Costs ÷ (Price per Unit − Variable Cost per Unit). Break-Even Revenue = Fixed Costs ÷ (1 − Variable Cost Ratio).

How to Use This Calculator

  1. Enter total fixed costs
  2. Enter selling price per unit
  3. Enter variable cost per unit
  4. View break-even quantity and revenue

Tips & Best Practices

  • Lower your break-even point by reducing fixed costs or increasing the selling price
  • Contribution margin (price − variable cost) is the key driver of break-even analysis
  • Break-even analysis is essential before launching any new product or business

Important Limitations

  • Assumes constant selling price and variable costs regardless of volume
  • Does not account for changes in demand at different price points
  • Fixed costs may change in reality as the business scales
