Maintenance & Reliability calculator
Corrective Maintenance Cost Calculator
Calculate the cost of a recorded group of corrective repairs. Enter whole jobs, average direct repair cost and separate group production-loss and recovery charges.
What this calculator does
- Total corrective repair expense and its associated production loss without confusing a group total with a per-repair average.
Formula used
- Direct repair cost = repair count × average direct cost per repair
- Other event cost = production loss + expediting and cleanup charges
- Total corrective cost = direct repair cost + other event cost
- Average cost per repair = total corrective cost ÷ repair count
Inputs explained
- Corrective Repairs: Completed repairs included in this cost record.
- Parts and Labor per Repair: Documented average direct repair cost for these comparable jobs.
- Total Production Loss: Contribution loss for this repair group excluding direct repair expense.
- Expediting and Cleanup Charges: Group charges excluded from direct repair cost and production loss.
How to use the result
- Best suited to corrective work-order review, repeated failure cost review.
- The arithmetic does not predict additional failures or repair duration. A heterogeneous repair mix requires appropriately weighted direct costs.
Current U.S. benchmarks
- U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
Common questions
- Are group charges repeated for every repair? No. Production loss and expediting are totals for the whole recorded group.
- Can the repair count include half a repair? No. Enter completed physical repair jobs; partial work should be recorded separately under your accounting policy.
- Does corrective maintenance always stop production? No. Enter zero production loss when the repair caused no unrecovered contribution loss.
- Why is the average blank when no repairs are counted? A per-repair cost has no denominator at zero jobs, although separately recorded charges may remain.
