Break-Even Calculator

Units you need to sell to cover fixed and variable costs.

Overview

Calculates the exact unit sales volume and revenue required for a business to cover all fixed and variable operating costs with zero profit and zero loss.

Formula & Calculation Method

Break-Even Units = Fixed Costs / (Selling Price per Unit - Variable Cost per Unit)

Contribution Margin = Selling Price - Variable Cost. Break-even occurs when total contribution margin equals total fixed overhead.

Worked Example: Retail Product with ₹50,000 Monthly Fixed Overhead

Inputs: Fixed Overhead = ₹50,000/month | Selling Price = ₹500/unit | Variable Cost = ₹300/unit

  • Contribution margin per unit = ₹500 - ₹300 = ₹200 per unit
  • Contribution margin ratio = 200 / 500 = 40%
  • Break-even volume = ₹50,000 / ₹200 = 250 units per month
  • Break-even revenue = 250 units × ₹500 = ₹1,25,000 per month

Summary: Fixed Costs = ₹50,000 | Margin = ₹200/unit | Break-Even Volume = 250 Units | Break-Even Sales = ₹1,25,000

Common Use Cases

  • Startup Financial Feasibility: Determine whether a new commercial venture has a realistic sales threshold.
  • Pricing Adjustments: Model how offering a 10% retail discount shifts the required monthly sales volume.
  • Cost Reduction Strategy: Calculate how cutting office rent or software overhead lowers the operational risk threshold.

Frequently Asked Questions

What is the difference between fixed and variable costs?

Fixed costs (rent, insurance, salaries) stay constant regardless of volume; variable costs (raw materials, packaging, shipping) rise with production.

What is Contribution Margin?

Selling price minus variable cost per unit; it is the amount of money each unit sale contributes toward paying off fixed costs.

How can a company lower its break-even point?

By raising selling prices, reducing unit material costs, or trimming fixed operational overhead.
