How to Calculate the Rate of Growth
- 1). Divide the final value by the initial value to find the overall rate of increase. For example, if the value of the company grew from $120,000 to $270,000 over 10 years, you would divide $270,000 by $120,000 to find the overall rate of increase to be 2.25.
- 2). Divide 1 by the number of years over which the growth occurred. In this example, you would divide 1 by 10 to find 0.1.
- 3). Raise the Step 1 answer to the Nth power, where N is the Step 2 result. In this example, you would raise 2.25 to the 0.1th power to get 1.084471771.
- 4). Take away 1 from the Step 3 result to find the annual rate of growth expressed as a decimal. In this example, you would take 1 away from 1.084471771 to find the annual rate of growth to be 0.084471771.
- 5). Change the annual rate of growth from a decimal to a percentage by multiplying it by 100. Completing the example, you would multiply 0.084471771 by 100 to find the annual growth rate to be about 8.447 percent.
