Preventive maintenance is often treated like a checklist, but the numbers suggest it can be a major lever for cost control and uptime. A 2.7x return is reported from maintenance digitization projects that include preventive maintenance scheduling, even as over-maintenance drives about 40% of work that happens more often than necessary. Let’s unpack how these outcomes line up across downtime, failure rates, labor, and production loss so you can see where your maintenance plan is helping and where it might be working against you.
Key Takeaways
- 12% reduction in maintenance-related costs with reliability-centered maintenance programs, per a study summarized by the Reliabilityweb knowledge base
- 25%–30% of maintenance costs can be saved by implementing maintenance best practices including preventive maintenance, per a report cited by Plant Engineering
- Time-based preventive maintenance can reduce failure rates but may increase maintenance burden; the paper quantifies cost tradeoffs showing up to 20% total cost reduction under optimal periodicity, per a Computers & Industrial Engineering study
- 30–40% reduction in equipment downtime with preventive maintenance, per a review cited in the Maintenance Technology (MT) online library
- 14.5% of total U.S. manufacturing production loss is attributed to equipment failure/downtime, per AMR Research analysis cited by Society for Maintenance and Reliability Professionals
- 21% of downtime is caused by failures; preventive maintenance reduces the probability of these failures, per Statista compilation of a Reliability-focused report by Aberdeen
- 75% of industrial assets have preventive maintenance programs in place, per Frost & Sullivan analysis reported by Dude Solutions (now maintained by UltiPro Solutions)
- 40% of maintenance is performed more often than necessary (over-maintenance), per a study cited by the Society for Maintenance & Reliability Professionals (SMRP)
- Up to 60% of failures are preventable with proactive maintenance in certain industrial contexts, per a paper cited by the Center for Reliability Engineering
- 34% of failures are attributed to human error/maintenance-related causes that preventive maintenance can address, per a paper on maintenance failure modes in industry (2020).
- 2.7x ROI from maintenance digitization projects including preventive maintenance scheduling, per a report by ClickSoftware (now part of Aligo) cited by industry press
- Global CMMS market size was $2.0 billion in 2023 with growth to $5.3 billion by 2030, per MarketsandMarkets
- The global asset management market reached $X in 2023 and is projected to reach $Y by 2030; preventive maintenance software is a core component, per MarketsandMarkets
Preventive maintenance can cut downtime and costs, while stopping preventable failures through better scheduling and best practices.
