CMMS ROI Calculator
Price the unplanned breakdowns a CMMS helps you avoid, then weigh that against the software and rollout cost. Your numbers stay in your browser.
Avoided failure cost / yr

How this is calculated
Every breakdown costs you twice: lost production while the line is down, plus repair and parts. A CMMS earns its keep by preventing some of those breakdowns. All figures below are your inputs; nothing here is a promise or a benchmark.
ROI% = (avoided cost − CMMS cost) ÷ CMMS cost × 100
Payback (months) = CMMS cost ÷ (avoided cost ÷ 12)
Honest caveats
- The reduction is your assumption. The slider is your expectation, not a guarantee. A CMMS only prevents breakdowns if the preventive work actually gets scheduled and done. Use a figure you can defend.
- Not every breakdown is preventable. Random and end-of-life failures happen regardless of maintenance discipline, so treat the reduction as applying to the preventable share only.
- Value per production hour should be contribution margin (revenue minus variable cost) for the affected line, not full revenue, which keeps this a conservative floor.
- Rollout is not free. This counts the software and rollout cost you enter, but internal time to build asset registries and PM plans is real and not included.
To pressure-test the reliability side, use the MTBF, MTTR and availability calculator and the preventive maintenance ROI calculator. To find where the hours are going, start with the machine downtime guide and the OEE calculation guide.
Turn avoided breakdowns into real numbers
Harmony connects your machines, work orders, and paperwork into one real-time operational layer, no rip-and-replace, so the breakdowns and downtime this calculator estimates become visible and actionable. Read the CLS case study.
