OEE & Factory Performance calculator
Yield Loss Cost Calculator
Yield loss cost converts scrapped and reworked parts into the real dollars they drain from a production run. Quality engineers, plant controllers, and continuous-improvement teams use it to put a price tag on first-pass yield problems so projects can be ranked by financial impact. It matters because a defect rate that looks small in percent can be enormous in dollars once material, labor, and disposition are included. The capture-rate factor lets you model how much of the theoretical loss you actually absorb after recovery or rework credit.
What this calculator does
- Estimate cost of yield loss from lost units, margin per unit, and containment cost.
- Use it when yield loss cost in oee and factory performance is being put through a oee and factory performance weighted-cost review.
- It multiplies defective quantity by cost per unit and a capture factor, then adds a fixed disposition cost to return total and per-unit yield loss dollars.
Formula used
- Weighted cost = quantity × rate × capture factor + fixed adjustment
Inputs explained
- Scrap and rework units:
- Cost per defective unit:
- Loss capture rate:
- Fixed disposition cost:
How to use the result
- Use it when scoping a quality improvement, building a cost-of-poor-quality case, or prioritizing which defect modes to attack first.
- It uses a single blended cost per unit, so mixed-value product or stage-dependent scrap cost (a part scrapped late costs more than one scrapped early) needs separate runs.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.6% of capacity (Federal Reserve, May 2026). New factory orders are up 2.3% year over year (Census).
Common questions
- How do you calculate yield loss cost? Multiply defective units by cost per unit and the capture rate, then add fixed cost. For 100 units at $45, an 80% capture rate, and $250 fixed, that is 100 × 45 × 0.80 + 250 = $3,850.
- What does the capture rate represent? It is the share of the theoretical loss you actually eat. At 80%, you recover or credit back 20% of the value through rework, salvage, or downgrade, so only $3,600 of the variable loss hits the run.
- What is yield loss cost per unit? It is total yield loss divided by the affected quantity. In the example, $3,850 across 100 units is $38.50 per piece, a useful number for comparing defect modes.
- Why include a fixed disposition cost? Scrap triggers fixed expenses regardless of quantity, such as a containment audit, sort labor, or a customer return shipment. The $250 adder captures those so the per-unit figure isn't understated.
- How is this different from a scrap rate? Scrap rate is a percentage of units; yield loss cost is the dollar impact. A 2% scrap rate means nothing to finance until you translate it, as here, into $3,850 of lost margin.
