Return on Investment (ROI) Calculator

This calculator works out how well an investment has performed by comparing its original value with what it is worth now. Return on investment is one of the simplest ways to check whether money tied up in a property, shares, a business or any other asset has been worthwhile, and to compare that performance against other investments you have made or are weighing up. You enter three figures: the original investment value, the current investment value, and the number of years you have held the asset. From those figures the calculator returns three results: the return on investment percentage, showing the overall gain or loss relative to what you originally put in; the return on investment amount, the actual dollar gain or loss over the full period; and the yield per year, which spreads that dollar gain evenly across the years held. Because yield per year is a simple average rather than a compounding annual growth rate, it suits comparing investments held over similar timeframes more than projecting future returns. The calculator does not account for tax, brokerage or other transaction fees, inflation, or any extra money added to or withdrawn from the investment along the way, so use the results as a starting point for comparing performance rather than a complete investment or tax record. Figures are indicative estimates only and are not financial advice.
