FSM ROI Calculator

Model the annual gain and payback period from implementing an FSM platform. Defaults match the worked example in the Buyer's Guide (15-truck HVAC, $2M revenue). Edit any input to fit your operation; switch between conservative, realistic, and optimistic scenarios to see the range.

How the annual gain breaks down

  • Utilization improvement $0
  • Unbilled-hour recovery $0
  • Invoice-to-cash freed working capital $0
  • Overtime reduction $0

How the math works. Utilization improvement multiplies your technician-hour pool by your improvement-% slider and credits the marginal contribution (billable rate − loaded cost) — the way the Buyer's Guide example computes the $113k figure. Unbilled-hour recovery applies the recovery slider to your currently lost hours (the gap between 100% and current utilization), credited at full billable rate. Invoice-to-cash converts the days-faster figure into freed working capital using your cost-of-capital input. Overtime reduction is a straight percentage cut on current OT spend.

Comparing to the Buyer's Guide example? The guide's "~$45,000 recovered" unbilled-hour line uses a more conservative interpretation than the literal 12%-of-currently-lost-hours math. The calculator applies the slider value to all currently-lost hours at the full billable rate, which produces a higher figure (~$97k at the realistic preset's 15-truck defaults). If the more conservative interpretation matches your operation better, drop the unbilled-recovery slider to ~5–6% to reproduce the guide's figure.

A payback period under 12 months is strong. 12–18 months is typical. Over 24 months should prompt hard questions about implementation confidence. All figures are stated before tax. Nothing leaves your browser.
