Upskill ROI · Investment Recovery
True course ROI including study-hour opportunity cost · 1- and 3-year net.
Every "free" course costs your hourly rate × study hours. Payback = (course + opportunity cost) / monthly salary lift. Under 18 months is a solid investment; over 36 months depends on whether the skill holds value that long.

Before you act on the result
Logic tools help expose a tradeoff, but they cannot see the full situation around the decision. Use the result to slow down the choice and name the assumption that matters most.
If one input drives the answer, test that assumption before treating the result as stable.
