Honest worksheets show every input label and refuse to pretend they are live quotes or official decisions.

totalCost = courseCost + timeHours × wage; benefit = raiseAnnual × years; ROI% = (benefit − cost)/cost × 100; paybackMonths = cost ÷ (raise/12).
Common mistakes
Mixing currencies, treating example presets as guarantees, and forgetting contingency or opportunity cost.
