About ROI Calculator

The Return on Investment (ROI) is a performance measure used to evaluate the efficiency or profitability of an investment. ROI compares the magnitude and timing of investment gains directly with the magnitude and timing of investment costs.

How to Calculate ROI

The basic formula for ROI is:

ROI = (Gain from Investment - Cost of Investment) / Cost of Investment

Where:

Annualized ROI

Annualized ROI is a measure of the average yearly return on an investment over a given time period longer than one year. It's calculated as:

Annualized ROI = [(1 + ROI)1/n - 1] × 100%

Where n is the number of years the investment is held.

Why ROI Matters

ROI is a popular metric because of its versatility and simplicity. Essentially, ROI can be used as a rudimentary gauge of an investment's profitability. This could be the ROI on a stock investment, the ROI a company expects on expanding a factory, or the ROI generated in a real estate transaction.
