Percentage Change Calculator
Calculate the percent increase or decrease between an original value and a new value. Ideal for prices, scores, or data comparisons.
How it works
Enter the original value (starting number) and the new value. The tool computes percent change using the standard formula:
Percent change = ((new − original) / |original|) × 100
If the original value is zero, the calculator will explain the situation because percent change is not defined in the usual way.
What is a Percentage Change Calculator?
A Percentage Change Calculator helps you find how much a value has increased or decreased over time, expressed as a percentage. It’s commonly used in business, finance, statistics, and everyday situations to quickly understand growth, loss, or change between two numbers.
For example, if a product’s price went from 50 to 75, the calculator shows a 50% increase. Similarly, if it dropped from 80 to 60, you’ll see a 25% decrease. This tool makes it easy to compare changes without doing manual math.
