Production downtime cost
Estimate the financial impact of a stop and separate production loss from recovery and repair costs.
Enter your values, then select Calculate.
Formula & assumptions
Unrecovered units = downtime hours × production rate × (1 − recovered % / 100). Lost contribution = unrecovered units × contribution margin. Total impact = lost contribution + additional repair labor + parts + scrap/restart + additional recovery cost.
Use contribution margin (selling price less avoidable variable cost), not sales revenue. Enter only additional costs attributable to this stop. Do not count the same cost in both margin and additional costs. Regular wages and fixed overhead are not automatically incremental losses. Recovered output reduces lost contribution but can create overtime or other recovery expenses. All amounts must use the same currency.
