Should I count every order closed this month?

Count only orders belonging to the fixed scheduled cohort and completed by their original deadlines. Other closures belong in a throughput measure.

Does a partially completed work order count?

No, unless the scheduled commitment itself was a separately defined task. Use a consistent completion rule established before reporting.

Can unscheduled emergency work improve this percentage?

No. It can explain missed commitments, but adding it to the numerator would mix two different populations.

Why keep a zero-order period undefined?

No scheduled commitment exists to evaluate. Reporting one hundred percent would imply observed performance without any due orders.

Maintenance & Reliability calculator

Work Order On-Time Completion Rate Calculator

Check whether scheduled work orders met their original commitments. Enter a fixed due-date cohort, orders completed on time and your required completion percentage.

What this calculator does

Compare on-time work order completions with the fixed scheduled cohort and its entered target.

Formula used

On-time completion = completed on time ÷ scheduled cohort × 100
Missed deadlines = scheduled cohort − completed on time
Missed share = missed deadlines ÷ scheduled cohort × 100
Target margin = on-time completion − minimum required completion

Inputs explained

Work Orders Completed on Time: Due-cohort items completed by their original recorded deadline.
Scheduled Work Orders: All items due in the fixed reporting cohort.
Minimum On-Time Completion: Your required on-time completion percentage for this cohort.

How to use the result

Best suited to work order schedule Review, maintenance commitment tracking.
An order count does not reflect labor hours or repair complexity. Tasks have equal weight regardless of asset criticality.

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).
