ROI worksheet

Ranges you can argue with. Not a single magic number.

Put in acres, season, labor, fuel, and fleet mix. The model returns a labor-cost picture, a band of hours that might come back, and a payback range. Every output is a planning assumption.

Your operation

Maintained acres In-play turf you would consider mapping. Default assumes a full 18-hole composite.

Season length (weeks) Weeks the full crew is on. Shoulder weeks still count if the iron is running.

Labor hours per week Mowing and related cutting labor, in season. Not the whole maintenance department.

Loaded labor rate (CAD / hour) Wages plus typical burden. Default C$35 is a planning placeholder — use yours.

Fuel spend per month (CAD) Mowing fleet fuel in a typical in-season month. Converted to a season total using weeks ÷ 4.345.

Current fleet mix (share of cutting hours) Fleet mix totals 100%.

Visible model assumptions (editable)

Hours are allocated by mix, with walk-behind weighted 1.35×, triplex 1.0×, rough 0.7× — because walk hours cost more attention per acre. Capture rates are the share of those hours a sequenced autonomous mix might return in a first serious season. Capex is a crude fleet-cost band, not a quote.
