Maintenance ROI Calculator
Estimate the financial impact of reducing unplanned downtime using your own assumptions, software costs and implementation budget.
These starting values are illustrative assumptions, not measured customer results. Use one currency for every monetary input. Replace the software cost with your quote and expected user count.
How the calculation works
- Annual avoided downtime cost = annual downtime hours × lost contribution per hour × assumed reduction.
- First-year cost = annual subscription + annual operating costs + one-time implementation.
- First-year ROI = (annual avoided cost − first-year cost) ÷ first-year cost × 100.
- Implementation payback = one-time implementation ÷ monthly benefit after recurring costs. No positive operating benefit means no calculated payback.
Build a defensible business case
Use lost contribution margin, not total sales revenue. Separate maintenance-related downtime from changeovers, demand shortages and other production constraints. Avoid counting recovered production twice through both downtime savings and throughput gains.
The model assumes steady savings throughout the year. It excludes ramp-up, financing, taxes, discounting and benefits such as reduced overtime or scrap. Add those to a separate business case with finance approval. Test a low, expected and high reduction scenario; this tool does not predict results or guarantee savings.
Read the downtime cost guide and check plan pricing before preparing a pilot budget.
