Step 2. Divide one by the number of years during the period
In the example, we assumed that the raises occurred over 10 years. Thus, we divide one by 10 to get 0.10.
Step 3. Calculate the annual rate of growth
To calculate the annual rate of growth, we now need to put our two previous answers together to get to a rate of growth. We take 1.5 and raise it to the 1/10th power.
You can type this into a calculator as 1.5^0.1. The calculator will tell you that 1.5^0.1 equals 1.0414.
Step 4. Convert to percentage
We subtract one from the previous answer (1-1.0414) to get the rate of growth, or 0.0414 per year. Multiply this by 100 to get an annual rate of growth of 4.14%.
