Formula & Mathematical Methodology
Break-Even Units = Fixed Costs ÷ (Price − Variable Cost)
Divides total fixed operational overhead by the contribution margin per unit.
How to Use This Break-Even Calculator
- Enter fixed overhead expenses, sales price per unit, and variable cost per unit.
Step-by-Step Worked Example
Scenario: $12,000 fixed costs, $40 unit price, $15 unit cost
1. Contribution margin: $40 − $15 = $25/unit
2. Break-even units: $12,000 ÷ $25 = 480 units
3. Break-even revenue: 480 × $40 = $19,200.00
Final Calculated Result: 480 Units ($19,200.00 Revenue)
What Does Your Result Mean?
At 480 units, net profit is exactly $0. Every unit sold past 480 contributes directly to profit.
Common Practical Applications:
- Startup business plans
- New product line feasibility
- Commercial lease evaluations
Important Limitations & Assumptions:
- Assumes fixed price and variable costs remain constant regardless of scale.
