Understanding the Calculations & Formulas

Return on Investment (ROI) is a popular financial metric used to evaluate the efficiency or profitability of an investment or compare the efficiency of several different investments. ROI tries to directly measure the amount of return on a particular investment, relative to the investment’s cost.

Formulas:

ROI (%) = [(Returned Value − Invested Value) ÷ Invested Value] × 100

Annualized ROI (%) = [(Returned Value ÷ Invested Value) ^ (1 ÷ n) − 1] × 100

Where:
n = Number of years of the investment

While simple ROI calculates absolute return without considering time frames, Annualized ROI provides a more accurate performance index of capital compound rates over multi-year durations.
