Percentage change
Find the increase or decrease from one value to another.
A clear answer. Here’s how.
Percentage change = (new − original) ÷ |original| × 100. The absolute original value makes the sign indicate increase or decrease when starting from a negative number. A zero original value has no defined percentage change.
