What Is ROI?

ROI stands for Return on Investment. It is a percentage that shows how much profit or loss an investment has generated compared with the original amount invested.

ROI can be useful when comparing the performance of different investments, projects, purchases, or business decisions.

ROI Formula

ROI = ((Final Value − Initial Investment) ÷ Initial Investment) × 100

Profit or loss is calculated by subtracting the initial investment from the final investment value.

Profit / Loss = Final Value − Initial Investment

ROI Example

Suppose you invest 10,000 and the investment grows to 12,500. Your profit is 2,500.

ROI = ((12,500 − 10,000) ÷ 10,000) × 100 = 25%

Therefore, the investment produced a total ROI of 25%.

Understanding Positive and Negative ROI

A positive ROI means the final investment value is greater than the original investment. A negative ROI means the final value is lower than the original investment and represents a loss.

For example, an investment of 10,000 that falls to 9,000 produces a loss of 1,000 and an ROI of -10%.

ROI and Investment Time

This calculator measures total ROI and does not calculate annualized return. Two investments can have the same ROI but produce that return over different periods of time. When comparing investments, consider the length of the investment period as well as the total return.

Important: ROI is a simple performance measure and does not automatically account for taxes, fees, inflation, dividends, cash-flow timing, or the time value of money. For important financial decisions, verify the figures and consider appropriate professional advice.
