Understanding Break-Even Analysis

Business Break-Even

Break-even is where revenue equals total costs. Below this point you lose money; above it you profit. Key formula: Fixed Costs ÷ (Price - Variable Cost) = Break-Even Units.

Investment Break-Even

Compare your investment's expected return to a risk-free alternative. The higher the return difference, the faster you'll come out ahead. But remember: higher returns usually mean higher risk.

Refinance Break-Even

Divide closing costs by monthly savings to find break-even months. If you'll move or refinance again before break-even, it's not worth it. Generally, aim for break-even under 3 years.

Frequently Asked Questions

What is break-even analysis?

Break-even analysis determines the point where revenue equals costs—no profit or loss. It helps answer:

  • Business: How many units must I sell?
  • Investment: When will this outperform alternatives?
  • Refinance: When will savings exceed closing costs?

How do I calculate business break-even?

Break-Even Units = Fixed Costs ÷ Contribution Margin

Where Contribution Margin = Selling Price - Variable Cost per Unit

Example:

  • Fixed costs: $50,000
  • Selling price: $100
  • Variable cost: $60
  • Contribution margin: $40
  • Break-even: $50,000 ÷ $40 = 1,250 units

When is refinancing worth it?

Break-Even Months = Closing Costs ÷ Monthly Savings

Refinancing is worth it if:

  • You'll stay in the home past break-even
  • Break-even is under 2-3 years (general rule)
  • You won't refinance again before break-even

What is contribution margin?

Contribution margin is selling price minus variable cost. It represents how much each sale contributes to covering fixed costs and generating profit.

  • Higher margin = fewer sales needed to break even
  • Margin ratio = Contribution Margin ÷ Selling Price
  • A 40% margin means 40¢ of each $1 covers fixed costs/profit
