Percentage Increase Calculator

Calculate the percentage increase (or decrease) between an original and a new value.

How Does This Calculator Work?

Percentage change is calculated as (new value − original value) ÷ original value × 100. A positive result means an increase; a negative result means a decrease.

Whether tracking a price change, a salary raise, or year-over-year growth, this calculator finds the percentage change between two numbers.

Example Calculation

Salary Raise Example

A salary that went from $50,000 to $65,000.

((65000-50000)/50000) × 100 = 30% increase.

Frequently Asked Questions

What does a negative result mean?

A negative percentage means the new value is lower than the original — in other words, a percentage decrease rather than an increase.
