ROI

Business Finance

Return on Investment (ROI) is gain or loss divided by cost of investment, expressed as a percentage. A $10,000 marketing campaign generating $30,000 in revenue (or $15,000 in profit, depending on definition) yields 200% or 50% ROI. Universal metric for evaluating investments, marketing campaigns, capex projects, and acquisitions. Watch the time dimension — 50% ROI in 1 year is excellent; 50% over 10 years is mediocre (about 4% annualized). Modern variants: ROAS (Return on Ad Spend) for marketing, IRR for time-sensitive analysis, NPV for projects with multi-year cash flows. ROI is widely abused — always clarify what's in numerator and denominator.
