Percent change is a way to describe a change in quantities. It helps you compare a new value to an old value.
Percent change can be an increase or decrease:
- A percent increase happens when the new value is more than the original value. For example, if the weight of a puppy went up over a month, you would have a percent increase.
- A percent decrease happens when the new value is less than the original value. For example, if the population of a town went down over a year, you would have a percent decrease.
