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.

Payback = (course + study_hours × hourly_wage) / monthly_lift. Opportunity cost is the wage you could have earned instead — most "free" courses are not free.

How to use

  1. Enter course cost, total study hours, your current hourly wage, and expected monthly salary lift.
  2. Opportunity cost = study_hours × hourly_wage.
  3. Payback = (course + opportunity cost) / monthly lift.
  4. Under 6 months = alpha bet · 6–18 = solid · 36+ = slow · no lift = negative ROI.

Examples

$1500 course · 120h · $35/h · $400 lift
Opportunity cost $4200 · Total $5700 · Payback 14.3 mo · Solid_Investment.
$0 course · 200h · $50/h · $100 lift
Opportunity cost $10000 · Payback 100 mo · Negative_ROI — find a cheaper path.

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.
