Maintenance Calculators
Maintenance Schedule Compliance Calculator
Use this calculator when you want to measure how much scheduled maintenance work was completed within the agreed schedule window.
Direct answer
Schedule compliance is calculated by dividing tasks completed within the agreed schedule window by tasks scheduled in that window, then multiplying by 100.
Definition
Schedule compliance shows how much scheduled maintenance work was completed within the agreed schedule window.
Formula
Schedule Compliance = (Tasks Completed on Time / Tasks Scheduled) x 100
What it measures
It measures schedule execution for all scheduled maintenance work.
Important limitation
A strong result can still hide schedule trimming, late deferrals, or weak schedule quality if the plan was changed heavily during the week.
How to calculate Schedule Compliance
Schedule compliance is calculated by dividing tasks completed within the agreed schedule window by tasks scheduled in that window, then multiplying by 100.
Formula
Schedule Compliance = (Tasks Completed on Time / Tasks Scheduled) x 100
Count the tasks scheduled in the period, count the tasks completed inside the agreed window, then divide and multiply by 100.
Explanation of every input
- Maintenance tasks scheduled
- Enter the value for the same asset scope and time period used in the rest of the calculation.
- Tasks completed within the agreed window
- Enter the value for the same asset scope and time period used in the rest of the calculation.
Worked example
- Tasks scheduled120
- Completed within the window102
(102 / 120) x 100 = 85%
Schedule compliance is 85%, with 18 tasks not completed inside the agreed window.
What the result means
Higher is generally preferable because more scheduled work is being completed as planned.
Schedule compliance shows whether the weekly or periodic plan is being executed as intended.
It should be reviewed with PM compliance so teams can separate all scheduled work from preventive work specifically.
Common interpretation mistakes
- Using schedule compliance and PM compliance as if they were the same measure.
- Removing work from the schedule late and then reading the percentage without noting those changes.
- Counting tasks with very different effort as equal without any supporting workload review.
Practical ways to improve or use the metric
- Tighten planning, material readiness, and labor coordination before the schedule period starts.
- Review reasons for schedule breaks, such as breakdowns, access loss, or missing parts.
- Use weekly schedule freeze rules where practical so execution can be measured more honestly.

Schedule Compliance FAQs
Practical questions maintenance teams often ask when reviewing this metric.
- How is schedule compliance different from PM compliance?
- Schedule compliance covers all scheduled maintenance work. PM compliance covers scheduled preventive maintenance work specifically.
- What is the agreed schedule window?
- It is the time window your organization uses to judge whether scheduled work was completed on time, such as the planned week or shutdown window.
- Should emergency work be counted in schedule compliance?
- Emergency work usually sits outside the scheduled task list. It may still affect compliance by interrupting the planned schedule, but it is not automatically part of the numerator or denominator.
- Why can schedule compliance be high while backlog still grows?
- Because the team may be completing the selected schedule window while more work is entering the backlog than the schedule can absorb.
