Manufacturing Break Even Calculator
Calculate break-even production units and break-even revenue based on fixed factory tooling investments and unit contribution margins.
Factory Fixed Costs & Contribution Margin
Manufacturing Break-Even Formula
Break-Even Units = Total Fixed Tooling & Plant Overhead ÷ (Unit Selling Price - Unit Variable Cost)- Fixed Costs: Tooling molds, factory lease, equipment financing, and supervisor base salaries.
- Unit Contribution Margin: Unit selling price minus variable material, direct labor, and machine power costs.
- Contribution Margin Ratio = Unit Contribution Margin ÷ Unit Selling Price.
Step-by-Step Worked Example
Calculation Steps:
- Unit Contribution Margin = $45.00 - $25.00 = $20.00 / unit
- Contribution Margin Ratio = $20.00 / $45.00 = 44.44%
- Break-Even Units = $60,000 / $20.00 = 3,000 units
- Break-Even Revenue = 3,000 units × $45.00 = $135,000
How to Use This Calculator
- 1Enter total fixed costs (tooling, dies, plant lease, supervisor salaries).
- 2Input unit selling price and unit variable production cost (materials, direct labor, power).
- 3Optionally add a target dollar profit to determine volume required for target return.
Assumptions & Limitations
- Selling price and variable costs remain constant over the volume range.
- All manufactured units are sold at the stated selling price.
Frequently Asked Questions
What if unit variable cost exceeds unit selling price?
Contribution margin becomes negative, meaning every unit produced incurs an active cash loss. No production volume can break even until variable costs are reduced or price is increased.
