Frequently Asked Questions
What is the ROI formula?
ROI = (final value - initial investment) / initial investment x 100. A gain of 4,500 on 10,000 invested is an ROI of 45 percent over the whole holding period.
How is CAGR different from ROI?
CAGR smooths the total return into an equivalent yearly growth rate. A 45 percent return over three years is a CAGR of about 13.2 percent per year, which makes investments of different lengths comparable.
What is a good ROI?
It depends on risk and time. Broad stock markets have historically returned around 7 to 10 percent a year. Any return should be judged against inflation and safer alternatives like bonds.
