How this calculator works
Return on investment answers the only question that matters about money you put to work: how much did it grow? The basic ROI formula is simple, (final value minus initial investment) divided by the initial investment, but it hides a trap: it ignores time. A 60% return sounds great until you learn it took 10 years. That is why this ROI calculator also computes the annualized return, the steady yearly growth rate that would produce the same result, which is the only fair way to compare investments held for different periods.
Use it to sanity-check real decisions. Compare a rental property against an index fund by annualizing both. Evaluate a business investment against simply leaving the money invested. And remember what ROI leaves out: it does not account for risk, taxes, fees or inflation, a 9% annualized return with wild swings and high fees is not the same as a smooth 9%. The growth curve plots your investment on the equivalent steady path so you can visualize the compounding behind the number.
