How much time does your team spend on planned preventive maintenance?
It does not matter if it is 20 percent of their day or 100 percent of their time; if you are not managing your preventive maintenance within the 10 percent rule, it’s likely that your PM program is not doing what it should for your assets.
The idea behind the 10 percent rule is that all preventive maintenance activities are completed within 10 percent of the due date in relation to the PM cadence. When performed on a regular basis, preventive maintenance can help extend the life of your assets. It can improve the overall operation of equipment, helping to reduce reactive issues and unscheduled downtime that can be a drain on your resources.
To truly gain the benefits of preventive maintenance, it is imperative that the team implements the 10 percent rule of preventive maintenance. For instance, how long do you give your team to complete monthly PMs? A week, two weeks, the entire month? To adhere to the 10 percent rule, it must be completed within three days of the start date—either 1-1/2 days before or 1-1/2 days after:
In doing so, you can guarantee that your PMs are completed in a timely manner to optimize asset performance.
Let us say you do not have the 10 percent rule in place and you give your team 30 days to complete PMs and still remain in compliance —after all, they are not the highest priority with reactive requests that come in). With that in mind, the following occurs:
- April: Busy month for the team, so PM completed on 4/28
- May: Able to complete PMs at the beginning of the month – officially checked off on 5/3
- June: Another busy month, so the PM isn’t completed until 6/20
Now, the issue is that between April and May, there are only five days between PMs. But, between May and June, there are nearly 50 days. Without being set on a regular schedule, a preventive maintenance program is simply ineffective.
If you leverage an automated asset management solution like 360Facility, you have the opportunity to set your service-level agreements, or SLAs, within the solution to easily track and set completion dates within the 10 percent rule. As a result, you can stay in compliance, extend the life of your assets and improve the overall operation of your equipment.

FAQs
The 10 percent rule states that for PMs to be effective, all PM activities must be performed within 10% of their due date. For example, if you give 30 days for your team to accomplish a PM activity, it should be accomplished within 3 (10% of 30 is 3) days of the due date.
What is the rule of preventive maintenance? ›
The 10% rule of preventive maintenance simply states that: A time-based PM must be accomplished in ten percent of the time frequency or it is out of compliance. Figure 2.2: This figure illustrates how many organizations perform a monthly (30-day) preventive maintenance strategy applied to a specific component.
What is the percentage of preventive maintenance? ›
The 80/20 rule, also known as the Pareto Principle, states that most things in life are not equally distributed. Take maintenance costs, for example. It's likely that just a few assets account for a large part your budget. Many maintenance departments aim for 80% preventive maintenance and 20% reactive repairs.
What is the formula for preventive maintenance? ›
Preventive Maintenance Compliance (PMC): This metric measures how many scheduled tasks have been completed within a given period. It's also useful for determining PM schedule effectiveness. The formula to calculate PMC is: number of completed PMs ÷ number of scheduled PMs x 100.
What is the 10 preventive maintenance? ›
The idea behind the 10 percent rule is that all preventive maintenance activities are completed within 10 percent of the due date in relation to the PM cadence. When performed on a regular basis, preventive maintenance can help extend the life of your assets.
What is the 10% rule? ›
What is the 10 rule? The ten percent rule of energy transfer states that each level in an ecosystem only gives 10% of its energy to the levels above it. This law explains much of the structural dynamics of ecosystems including why there are more organisms at the bottom of the ecosystem pyramid compared to the top.
How much can preventive maintenance save? ›
Preventive maintenance advantages are tangible; it can reduce costs by 12-18% and generate a remarkable 400% return on investment. Setting aside maintenance resources before issues arise has short-term costs, but the long-term benefits are real.
What is basic preventive maintenance? ›
Preventive maintenance (PM) is the regular and routine maintenance of equipment and assets in order to keep them running and prevent any costly unplanned downtime from unexpected equipment failure.
What is the ratio of preventive maintenance? ›
In the 6:1 Rule, the purpose of a condition inspection PM is to find degradation and rectify the situation before failure. The theory is you inspect at a frequency where you find degradation once in every six checks. Thus you get the 6:1 preventive maintenance ratio.
What is the preventive maintenance rate? ›
Preventive Maintenance Compliance is determined by dividing the number of completed PM work orders by the number of scheduled work orders within the timeframe, then multiplying by 100 to get a percentage.
1 The net present value, or NPV, of preventive maintenance is calculated by comparing repair, energy and replacement costs for PM and non-PM scenarios and bringing the costs to a present value using an assumed discount rate. The PM scenario value is subtracted from the non-PM value.
What is the 10 rule of preventive maintenance? ›
The 10% Rule of PM states that if a PM is executed within 10% of a time frequency then it is considered compliant and within the standard.
How do you calculate maintenance percentage? ›
Planned maintenance percentage is calculated by dividing the total number of planned maintenance hours in a given period by the total number of hours spent on all maintenance in the same period. This number is multiplied by 100 to give you the final percentage.
How do you measure preventive maintenance? ›
A high PM effectiveness ratio indicates that your organization is prioritizing preventive activities over reactive ones. There is a PM Effectiveness Ratio: Divide the total planned maintenance hours by the total unplanned maintenance hours. Multiply the result by 100 to express it as a percentage.
What is the maintenance golden rule? ›
The gist of this rule is that for every six preventive maintenance tasks you do, you should find one corrective task. If you end up doing more PMs for each corrective task, you're doing too much PM. If you have more corrective tasks, you're doing too little.
What is the 10 rule in ecology? ›
On average only 10 percent of energy available at one trophic level is passed on to the next. This is known as the 10 percent rule, and it limits the number of trophic levels an ecosystem can support.
