Calculate Unit Contribution Margin (Price - Variable Cost)
Divide Total Fixed Costs by Unit Contribution Margin
Calculate Minimum Break-Even Sales Revenue
Quick Answer & Understanding Your Result
A Break-Even Calculator determines the exact sales volume (units) and revenue required to cover all fixed and variable costs, where net operating profit equals zero.
Cost-Volume-Profit (CVP) Fundamentals
- Fixed Costs (FC): Overhead expenses that remain constant regardless of sales volume (e.g. rent, salaries, insurance).
- Variable Cost per Unit (VC): Direct production costs incurred per item manufactured or sold (e.g. materials, packaging, commission).
- Contribution Margin (CM): Price minus variable cost (CM = P - VC), representing the money available to cover fixed overhead.
- Contribution Margin Ratio: Percentage of each sales dollar contributing to covering fixed overhead (CM% = CM / P).
Business & Startup Uses
- Product Pricing & Launch Strategy: Establishing minimum production runs before a new product line becomes profitable.
- Target Profit Planning: Calculating sales volume needed to generate a specific net operating profit.
Enter fixed costs, price per unit, and variable cost per unit above to calculate your break-even threshold instantly.
Formula & Calculation Logic
Mathematical FormulaCost accounting formulas:
- Divides aggregate overhead costs by the per-unit contribution margin (P - VC).
- To compute a target profit: Units = ( Fixed Costs + Target Profit) div CM.
Step-by-Step Guide
Enter Total Fixed Costs
Input monthly or annual overhead expenses (e.g. $15,000).
Enter Price & Variable Cost per Unit
Input sale price per unit (e.g. $50) and direct production cost (e.g. $20).

Worked Examples Table
| Example | Input Values | Calculated Result | Explanation |
|---|---|---|---|
| Fixed Costs: $15,000 | Price: $50 | Variable Cost: $20 | Contribution Margin = $50 - $20 = $30. $15,000 ÷ $30 = 500 units. | ||
