Return of Investment (ROI) Calculator

Calculate the return of investment (ROI) by entering the investment amount and the return amount.

For the complex return on investment calculator, enter the numbers of shares and the average buy or the amount invested.
If you don't know the average buy, enter the amount invested only, the average cost will be automatically calculated, and the same if you don't know the amount invested, enter the average buy only, the amount invested will be calculated automatically.

Subtract the amount invested from the returned amount of investment, then divide the new number by the amount invested, and finally multiply the result by 100 to get the return on investment.

Formula:
ROI = [( Amount Returned - Amount Invested ) ÷ Amount Invested ] x 100
