How do you calculate work order completion rate?

Divide on-time completed work orders by scheduled work orders and multiply by 100. With 184 completed on time out of 210 scheduled, that is 184 ÷ 210 × 100 = 87.6%.

What is a good work order completion rate?

World-class maintenance organizations run 90% or higher schedule compliance. The 87.6% in our example sits 7.4 points below a 95% target, signaling the schedule is being broken too often by reactive work.

What is the difference between completion rate and schedule compliance?

They are often used interchangeably. Strict schedule compliance counts only work both scheduled in advance and completed in its window; loose completion rate may count any closed work order, which inflates the number.

Why is my completion rate below target?

Common causes are too much emergency work breaking the schedule, jobs scheduled without confirmed parts or craft availability, and over-loading the weekly schedule beyond available wrench time.

Should I count partially completed work orders?

No. Count a work order as complete only when the job is fully done within the scheduled period. Counting partials masks chronic carryover and overstates performance.

How often should I measure work order completion rate?

Weekly, aligned to your scheduling cycle, so each scheduler review acts on the prior week's number. Roll the weekly figures into a monthly trend for KPI reporting.

Maintenance & Reliability calculator

Work Order Completion Rate Calculator

Work Order Completion Rate is the share of planned maintenance work orders your crew actually finishes on time, expressed as a percentage of everything that was scheduled for the period. Maintenance planners, reliability engineers, and CMMS administrators track it weekly to see whether the planning and scheduling function is real or just a wish list. A high completion rate means jobs are kitted, scheduled, and executed as planned; a low one means firefighting, parts stockouts, or over-scheduled craft hours. It is one of the most honest indicators of whether a plant is in proactive or reactive maintenance mode.

What this calculator does

Measure the percentage of scheduled work orders completed on time within the planning period.
Use it in weekly scheduling meetings to see whether the plan is realistic and whether execution discipline is holding.
It computes the percentage of scheduled work orders completed on time and the point gap between that result and your schedule compliance target.

Formula used

Work-order completion rate = completed on-time work orders ÷ scheduled work orders × 100
Gap to target = completion target - work-order completion rate

Inputs explained

Completed on-time work orders:
Scheduled work orders:
Schedule compliance target:

How to use the result

Use it at every weekly scheduling review and in monthly reliability KPIs to judge how well planned maintenance is executed versus planned.
It counts work orders, not labor hours or job value, so a backlog of small jobs and a missed major shutdown task can look identical.

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).
