Calculating Percent Changes Percent change is the change between the original value and a new value. To calculate percent change, you have to calculate the change itself (subtract one number from the other), then divide by the original number, then multiply by 100. The resulting number is the percent change. Multiply the rate of change by 100 to convert it to a percent change. In the example, 0.50 times 100 converts the rate of change to 50 percent. However, if the numbers were reversed such that the population decreased from 150 to 100, the percent change would be -33.3 percent. To find out the growth rate of your business you need to calculate percent change using the equation below. Percent Change Formula.
