A great maintenance planner doesn’t just plan jobs — they track and measure their effectiveness. Without clear metrics, it’s impossible to know whether planning efforts are reducing downtime, increasing reliability, or improving efficiency.
Tracking key maintenance KPIs (Key Performance Indicators) gives planners the visibility they need to identify gaps, prioritise improvements, and demonstrate the value of structured planning.
In this article, we’ll explore 5 essential KPIs every maintenance planner should monitor, why they matter, and how they tie directly into better planning outcomes.
1. Schedule Compliance (%)
What It Measures:
Schedule compliance tracks how much of the planned work is completed as scheduled, within the designated week or period. It’s a clear measure of how effectively your planning and scheduling process is being executed.
Why It Matters:
A low schedule compliance score often points to reactive work creeping into the schedule, poor planning readiness, or a lack of alignment with operations. Planners can use this metric to pinpoint where the breakdown is happening — whether it’s unplanned jobs, missing parts, or scheduling conflicts.
Improvement Tip:
To boost schedule compliance, focus on freezing the weekly schedule and protecting it from last-minute changes. Work with operations to agree on priorities ahead of time and build in a small buffer for unexpected reactive work. Consistency is key — a stable, realistic schedule sets expectations for both technicians and operations, making compliance far more achievable.
2. Planned vs. Unplanned Work Ratio

What It Measures:
This KPI looks at the proportion of planned work compared to reactive or unplanned work. Ideally, organisations aim for 80% planned work and 20% unplanned, though the exact ratio depends on asset criticality and maturity.
Why It Matters:
A high ratio of unplanned work is a sign that your preventive maintenance strategy or job readiness is falling short. It also puts significant strain on the maintenance team, often leading to increased overtime and stress.
Improvement Tip:
The Playbook covers strategies for moving from a reactive to a proactive planning culture, with detailed steps on building job plans and preventive maintenance schedules that reduce the firefighting mode.
3. Maintenance Backlog (Weeks)
What It Measures:
This KPI represents the total estimated man-hours of work in your backlog, divided by the number of hours available from your maintenance team. It’s typically expressed in weeks of labor capacity.
Why It Matters:
Too much backlog (e.g., 8+ weeks of work) means critical jobs risk being delayed, while too little backlog may indicate a lack of forward planning. Keeping this KPI in check ensures the team has a healthy pipeline of ready-to-execute work.
Improvement Tip:
A regular backlog audit (like the one outlined in our post: How to Audit Your Maintenance Backlog for Better Efficiency) will help identify stale work orders, prioritise tasks, and ensure your planning pipeline is properly balanced.
4. Maintenance Cost Per Asset
What It Measures:
This KPI tracks the total maintenance costs associated with each asset or asset group, including:
- Technician labor time
- Spare parts and materials
- Contractor support
- Any additional costs related to maintenance interventions
Why It Matters:
This KPI allows planners to spot cost outliers within similar asset groups. For example, if two identical pumps have drastically different maintenance costs, it might highlight issues with job quality, PM frequency, or asset condition.
Improvement Tip:
Combine this KPI with CMMS data and failure history to pinpoint where over-maintenance or poor reliability is driving cost. Tools from The Maintenance Planner’s Playbook can help structure this analysis, particularly with cost tracking templates and asset-level reporting.
5. Asset Availability / Uptime (%)
What It Measures:
This KPI measures the percentage of time critical assets are available and operational, compared to their expected runtime.
Why It Matters:
High asset availability is the ultimate indicator of planning success. Every well-planned job, spare part, and PM task contributes to keeping assets online. Planners have a direct influence on uptime by ensuring jobs are executed on time and correctly.
Improvement Tip:
A planner’s role in schedule compliance, backlog control, and PM audits all feed into this KPI. For a deeper dive into strategies for improving uptime, see 5 Reasons Your Maintenance Planning Might Be Failing.
Conclusion: Why KPIs Matter to Planners
The role of a maintenance planner is about more than just scheduling tasks — it’s about shaping the culture of reliability and driving measurable improvements across the entire maintenance process. By tracking these 5 KPIs, planners can quickly identify bottlenecks, highlight inefficiencies, and turn raw CMMS data into actionable insights. More importantly, these KPIs give planners a way to demonstrate value to operations and leadership, building trust and accountability in the planning process.
Improving these metrics isn’t just about reporting numbers — it’s about creating a structured maintenance environment where technicians know what’s coming, spare parts are ready, and downtime is minimized. A planner who masters these KPIs doesn’t just keep the wheels turning — they become a key driver of performance and operational success.
