A Percentage Change Calculator is a tool used to calculate the percentage change between two values, showing how much something has increased or decreased relative to its original value. This is often used to track changes in prices, quantities, or other data points over time.

What is Percentage Change?

The percentage change expresses how much a value has increased or decreased relative to its initial value, and it is calculated using the following formula:

Where:

  • New Value = The final or updated value
  • Original Value = The initial value before the change

If the result is positive, it represents a percentage increase, and if the result is negative, it represents a percentage decrease.
