How do you calculate annual rate of return over multiple years in Excel?
Annualized return
This is displayed as a percentage, and the calculation would be: ROI = (Ending value / Starting value) ^ (1 / Number of years) -1. To figure out the number of years, you'd subtract your starting date from your ending date, then divide by 365.
To calculate the annualized portfolio return, divide the final value by the initial value, then raise that number by 1/n, where "n" is the number of years you held the investments. Then, subtract 1 and multiply by 100.
Average Return Example
For instance, suppose an investment returns the following annually over a period of five full years: 10%, 15%, 10%, 0%, and 5%. To calculate the average return for the investment over this five-year period, the five annual returns are added together and then divided by 5.
In other words, you multiply the shorter-term rate of return by the number of periods that make up one year. A monthly return would be multiplied by 12 months.
How to calculate the average growth rate? To calculate the average growth rate of your company, you first need to divide the present by the past value, then multiply that number by 1/N (where N is the number of years). Finally, subtract the result by 1, and you'll get the average growth rate.
- Subtract the initial investment you made at the beginning of the year (“beginning of year price” or “BYP”) from the amount of money you gained or lost at the end of the year (“end of year price” or “EYP.”)2. ...
- Multiply the number by 100 to get the percentage.
Divide 1 by the number of years you held the investment. For example, if you held the investment for five years, divide 1 by 5 to get 0.2. Raise the Step 2 result to the power of the Step 3 result. In this example, raise 1.35 to the 0.2 power to get 1.0619.
ROI is calculated by subtracting the initial cost of the investment from its final value, then dividing this new number by the cost of the investment, and finally, multiplying it by 100.
- Annualized Rate of Return = (45 * 100 / 15 * 100)(1 /5 ) – 1.
- Annualized Rate of Return = (4500 / 1500)0.2 – 1.
- Annualized Rate of Return = 0.25.
