Growth Rates

A growth rate is the percentage change in a quantity over a period of time. It is calculated by dividing the final value by the initial value and then subtracting 1. For example, if a company's revenue was $100 million in 2019 and $120 million in 2020, its growth rate would be 20%.

Growth rates are used to measure the performance of businesses, economies, and other entities. They can be used to compare different entities over time or to track the performance of a single entity over time. Growth rates can also be used to forecast future growth.

There are two main types of growth rates: nominal and real. Nominal growth rates are calculated using the nominal values of the quantities being measured. Real growth rates are calculated using the real values of the quantities being measured. Real growth rates take inflation into account, so they provide a more accurate measure of the change in the quantity being measured.

Growth rates can be positive or negative. A positive growth rate indicates that the quantity being measured is increasing. A negative growth rate indicates that the quantity being measured is decreasing.

Growth rates are an important tool for understanding the performance of businesses, economies, and other entities. They can be used to compare different entities over time or to track the performance of a single entity over time. Growth rates can also be used to forecast future growth.
