Growth rates are used to express the annual change in a variable as a percentage.
A positive growth rate indicates that the variable is increasing over time; negative growth rate that it decreases.
Growth rates can be useful in evaluating a company’s performance and predicting future results.
Growth rates are calculated by dividing the difference between the end and start values for the analyzed period and dividing this difference by the start value.
Time periods used for growth rates, most commonly year, quarter, month and week.
