Calculate the annual growth rate over multiple years

The growth rate is an essential metric for evaluating investment opportunities. Cities, schools, and other organizations frequently rely on the annual population growth rate to forecast the demand for infrastructure, services, and more. This statistical indicator is both vital and practical, and it’s not difficult to calculate on your own.

Steps

Calculate growth over the course of a year

Obtain the initial value. To calculate the growth rate, you need the starting value. This could be the population, revenue, or any data point you're considering at the beginning of the year.

For example, if the population of a village is 125 at the start of the year, the starting value would be 125.

Obtain the final value. To calculate growth, you not only need the starting value but also the final value. This could be the population, revenue, or any data point you're analyzing at the end of the year.

For example, if the population of a village at the end of the year is 275, the final value would be 275.

Calculate the growth rate for the year.

\frac{Final value - Initial value}{Initial value} * 100

For example, a village starts the year with a population of 150 people and grows to 275 people by the end of the year. The way to calculate the growth rate for the year is as follows:

= \frac{275 - 150}{150} * 100

= \frac{125}{150} * 100

0.8333 * 100

83.33 %

Calculate the annual growth rate over multiple years

Obtain the initial value. To calculate the growth rate, you need the initial value. This could be the population, revenue, or any data point you're analyzing at the beginning of the period.

For example, if a company's revenue at the start of the period is $10,000, the initial value would be $10,000.

Obtain the final value. In addition to the starting value, you also need the final value for calculating the annual growth rate. This could be population, revenue, or any data you're looking at at the end of the period.

For example, if the company’s revenue at the end of the period is $65,000, then the final value is $65,000.

Determine the number of years to consider. Since you're measuring growth over a period, you need to know how many years are in that period.

For example, if you want to calculate the annual growth rate of a company’s revenue from 2011 to 2015, then the number of years is 4, which is the difference from 2011 to 2015.
