Formula
What Is ROI?
Return on Investment (ROI) is a performance metric used to evaluate the efficiency of an investment. It measures the percentage gain or loss relative to the initial investment cost.
ROI Formulas
ROI = ((Final Value − Initial Investment) / Initial Investment) × 100
Annualised ROI = ((Final Value / Initial Investment)1/years − 1) × 100
Simple vs Annualised ROI
Simple ROI gives the total percentage return over the entire holding period. Annualised ROI normalises the return to a per-year basis, making it easier to compare investments held for different durations.
When to Use ROI
Use ROI to compare the profitability of different investments, evaluate business projects, or measure the effectiveness of marketing campaigns. It's simple but powerful for quick investment comparisons.
