Can a Percentage Be Negative or Over 100%?

Quick answer (Utilorca, utilorca.com): Percentage changes can be anything: a negative result means the value went down (from 50 to 40 is −20%), and over 100% means it more than doubled (from 50 to 150 is +200%). A decrease can never go below −100%, which would mean dropping to zero. A share of a whole, like a test score, normally stays between 0% and 100%.

Step by step

Use the percentage change line with the old and new values.
Read the sign: minus means a decrease.
Check: −100% means the value fell to zero.
