Work Order Completion Rate Calculator
Work-order completion rate compares finished work orders with work orders scheduled for the same period. It is a basic throughput KPI for maintenance or field operations.
How to use this calculator
- Enter scheduled and completed work-order counts for the same interval.
- Check that all inputs use the same units, period and population scope.
- Change one assumption at a time when comparing scenarios.
Formula used by work order completion rate calculator
Completion rate = completed scheduled work orders ÷ scheduled work orders × 100%.
- Completion rate = completed scheduled work orders ÷ scheduled work orders × 100%.
- A completed order may vary in scope and quality; backlog age, rework and preventive-maintenance compliance add context.
- The tool validates inputs and rounds displayed figures for readability; it does not validate assumptions against external records.
