Online Course ROI Basics: Cost, Time, and Raise Assumptions
Adds cash and time cost, multiplies your raise assumption by years, then reports ROI and simple payback. This guide explains the worksheet assumptions in plain language.
Formula in plain language
totalCost = courseCost + timeHours × wage; benefit = raiseAnnual × years; ROI% = (benefit − cost)/cost × 100; paybackMonths = cost ÷ (raise/12).
What this is not
Educational estimate only—not career, tax, or investment advice. Raises are assumptions you enter, not guarantees.
