ROI Calculator

How the ROI Calculator Works

This calculator helps you determine your Return on Investment (ROI) by comparing the initial cost of an investment to its final value. ROI is one of the simplest and most widely used metrics for evaluating profitability.

Formula Used

The calculator uses the standard ROI formula:

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

Example

Example for an investment that grew from $1,000 to $1,500:

ROI = ((1500 − 1000) ÷ 1000) × 100
    = (500 ÷ 1000) × 100
    = 50%
