Break-Even Calculator

Calculate break-even units, required revenue, and contribution margin to eliminate business risk.

Overview & Mechanics

How the Break-Even Calculator Works

The Break-Even Calculator determines the exact sales volume in units and gross revenue required to cover all operating fixed overheads and variable unit costs, establishing the threshold where net business profit transitions from negative to positive.

Step-by-Step Tutorial

How to Use This Tool in Simple Steps

01

Enter your total recurring fixed costs for the period (salaries, office rent, software, utilities).

02

Enter your variable cost per unit (raw materials, production, packaging, sales commissions).

03

Enter your selling price per unit.

04

Optionally set a target sales unit forecast to evaluate projected net profit or loss above the break-even threshold.

Mathematical Logic

Formulas & Computational Methodology

Contribution Margin per Unit = Selling Price - Variable Cost per Unit. Contribution Margin Ratio (%) = (Contribution Margin / Selling Price) × 100. Break-Even Units = Ceil(Fixed Costs / Contribution Margin). Break-Even Revenue = Break-Even Units × Selling Price.
Case Study Scenario

Real-World Walkthrough

A digital agency or manufacturing firm with $24,000 in monthly fixed overhead selling a product for $120 with $40 in unit variable costs earns an $80 contribution margin per unit (66.7% ratio). The company must sell exactly 300 units ($36,000 in revenue) each month to break even; the 301st unit generates immediate net profit.
Important Caveats

Limitations & Assumptions

  • Assumes variable costs remain linear and do not change due to supplier volume discounts.
  • Assumes all produced units are sold at the stated uniform price without discounting.
Common Questions

Frequently Asked Questions

Contribution margin reveals how much cash each sale contributes toward paying off fixed business rent and salaries. High revenue with negligible contribution margin can cause a business to become insolvent even as sales scale.
