When Excel is in formula mode, type in the formula. Third, raise 1.8 to the 1/10th power to get 1.061. To calculate the Average Annual Growth Rate in excel, normally we have to calculate the annual growth rates of every year with the formula = (Ending Value - Beginning Value) / Beginning Value, and then average these annual growth rates. To determine the percentage growth for each year, the equation to use is: Percentage Growth Rate = (Ending value / Beginning value) -1 The reason for one half is because your net new investments are put into the pool over time, not all at once at the beginning. Average annual return = Sum of earnings in Year 1, Year 2 and Year 3 / Estimated life = ($25,000 + $30,000 + $35,000) / 3 = $30,000.

Another way of thinking about this is to say that, if we lose 50% of our investment, we need a 100% return to break even. Fifth, multiply 0.061 by 100 to find the average annual return over the 10 years is 6.1 percent. Compound interest is the interest on a loan or deposit calculated based on both the initial principal and and the accumulated interest from previous periods.

It is calculated by taking the arithmetic mean of a series of growth rates. Let's imagine that we instead have the following returns for our portfolio over three years: If volatility declines, the gap between the simple and compound averages will decrease. … Let us explain. The more common method of calculating averages is known as the arithmetic mean, or simple average.

Calculate that by using the "Rule of 72": Divide 72 by the number of years it takes an investment to double in value, and that is the compound rate of growth over the period of time applied.

Over 10 years, however, the difference becomes larger: $6.83, or a 5.2% overstatement.
