Automation ROI — CNC Machine-Tending

Payback and 5-year value of a cnc machine-tending from capex, labor displaced and throughput uplift.

Installed cell cost ($)Loaded labor rate ($/hr)Operators displaced (FTE)Annual hours per FTEThroughput/quality uplift value ($k/yr)Annual maintenance + power ($k/yr)

Net annual saving ($k/yr)

Simple payback (months)

5-year net value ($k)

Tending robots earn at night: the uplift parameter should encode the unmanned hours a machine now cuts. A robot that lets two CNCs run a ghost shift effectively doubles spindle hours for one operator's wage — the classic high-mix shop's first automation win.

Formula

payback = capex / (labor×FTE×hrs + uplift − opex)
