Formula & How It Works

Contribution Margin = Selling Price − Variable Cost per Unit
CM Ratio = Contribution Margin ÷ Selling Price × 100
Break-Even (Units) = Total Fixed Costs ÷ Contribution Margin
Break-Even (Revenue) = Break-Even Units × Selling Price
Margin of Safety = Actual Sales − Break-Even Sales

Worked Example

Scenario: Fixed costs ₹1,50,000/month, Selling price ₹500/unit, Variable cost ₹300/unit.

Contribution Margin = ₹500 − ₹300 = ₹200/unit

Break-Even = ₹1,50,000 ÷ ₹200 = 750 units/month

Break-Even Revenue = 750 × ₹500 = ₹3,75,000/month

If you currently sell 1,200 units/month, Margin of Safety = 1,200 − 750 = 450 units (37.5%)

When to Use This Calculator

  • Evaluate whether a new product launch is viable at a given price point
  • Set monthly sales targets for store staff
  • Decide if you should reduce fixed costs (move to smaller premises) or increase prices
  • Assess the financial risk of opening a new store location
  • Calculate how many units a new distributor needs to sell to be profitable

Frequently Asked Questions

The break-even point is the level of sales at which total revenue equals total costs, resulting in zero profit or loss. Above this point, every unit sold contributes to profit.
Fixed costs remain the same regardless of sales volume — rent, salaries, insurance. Variable costs change with production or sales volume — raw materials, packaging, commissions.
Contribution Margin = Selling Price − Variable Cost per Unit. Break-Even = Fixed Costs ÷ Contribution Margin. The contribution margin tells you how much each unit sold contributes toward covering fixed costs.
If your break-even is very high, you may need to increase your selling price, reduce variable costs, or reduce fixed costs. It helps you set the floor price below which selling at any volume still results in a loss.
Margin of Safety = Actual Sales − Break-Even Sales. It shows how much sales can fall before you start making a loss. Higher margin of safety means lower business risk.
