Notice that 1.10 can We could then calculate the population in later years: A friend is using the equation Pn = 4600(1.072)n to predict the annual tuition at a local college. She says Total fertility rate 4. Growth rate (yearly) 2.81 %. immigration/year 1K. Starting population 60K. First birth given (age) 21. Human age (average) 80. Timespan To calculate the Compound Annual Growth Rate in Excel, there is a basic formula =((End Value/Start Value)^(1/Periods) -1. And we can easily apply this formula
