Quick answer
PM ROI improves when reactive work is expensive (callbacks, overtime, parts expedite) and when PM completion is measurable. This calculator compares expected reactive reduction to program cost for directional planning.
Overview
Preventative maintenance pays off when it reduces emergency labor, parts expedites, and customer churn. The hardest part is honest baselines: what you spend reactively today, and what fraction PM can credibly shift.
Use outputs to prioritize pilots and template governance—not as a substitute for finance-grade modeling.
How to use this tool
Enter your best estimate of annual reactive spend you believe PM can influence, the annualized cost of running the PM program (labor + parts + tooling), and an expected reduction percentage your team agrees is realistic after 2–3 cycles.

Limitations
This is a simplified directional model. It ignores tax, cash timing, contract penalties, and mixed fleets with different economics. Validate with your CFO for capital decisions.

- What counts as reactive spend?
- Emergency dispatches, overtime tied to failures, expedited parts, warranty rework, and revenue lost from missed SLAs—whatever your team agrees is addressable by better PM discipline.
