Cost Per Unit Calculator
Roll variable and fixed costs into a true cost per unit, then see gross margin per unit, margin percent, and the volume where you break even. Your numbers stay in your browser.

How this is calculated
Variable costs are per unit and constant. Fixed overhead is spread across the volume you enter, so cost per unit falls as volume rises.
Margin% = gross margin / unit ÷ price × 100
Breakeven uses contribution margin, price minus variable cost, to cover fixed overhead:
What to keep in mind
- Contribution margin drives breakeven. Only price minus variable cost pays down fixed overhead. If price is at or below variable cost, there is no breakeven and it is shown as not reachable.
- Fixed cost per unit is volume-dependent. Total cost per unit is only valid at the volume you entered. Produce fewer units and each one absorbs more fixed cost.
- Classify costs carefully. Mislabeling a fixed cost as variable, or the reverse, distorts both margin and breakeven.
- Steady state only. Startup, changeover, and scrap costs are not separated out here. Fold them into your inputs if they are material.
Cost per unit improves when downtime and idle time shrink and throughput rises. See where capacity is lost with the OEE calculator, then connect it to durable cost reduction through lean manufacturing and the manufacturing ROI calculator.
See cost and throughput on one live layer
Harmony connects your machines, systems, and paperwork into one real-time operational layer, no rip-and-replace, so cost per unit and the throughput behind it stay visible as they change. Read the CLS case study.
