Return On Investment Calculator

Reset Data

Use this return on investment calculator to calculate your return on investment (ROI) as a percentage and work out your absolute investment return. Simply enter the amount invested in the “Invested amount” box and the amount returned in the “Returned amount” box. The calculator will then display the gain or loss and return on investment.

Return on Investment (ROI) Formula

This calculator tool works by using the following ROI formula:

ROI = (Net return on investment / Cost of investment) * 100

For example, if you invest $10,000 and make $12,000, your net return on investment is $12,000 – $10,000 = $2,000. You would then divide $2,000 by the cost of investment ($10,000), and multiply it by 100. This would give a return on investment of 20%.
