Calculate Percentage Increase

What is a Percentage Increase?

A percentage increase represents how much a value has grown relative to its original amount, expressed as a percentage. It measures the upward change between an original value and a new, higher value.

This calculation is commonly used in finance for tracking salary raises, investment returns, price inflation, and business revenue growth. Understanding percentage increase helps you compare growth rates across different contexts.

How to Calculate Percentage Increase

Follow these steps to calculate the percentage increase between two values:

  1. Find the difference: Subtract the original value from the new value
  2. Divide by original: Divide the difference by the original value
  3. Multiply by 100: Convert the decimal result to a percentage

Formula

Percentage Increase = ((New Value - Original Value) / Original Value) × 100%

The formula calculates the relative change from the original value. A positive result indicates an increase, while a negative result would indicate a decrease.

Example

Salary Increase Example

Problem: Your salary increased from $50,000 to $55,000. What is the percentage increase?

Solution:

  1. Difference: $55,000 - $50,000 = $5,000
  2. Division: $5,000 / $50,000 = 0.10
  3. Percentage: 0.10 × 100 = 10%

Frequently Asked Questions

What if the new value is smaller than the original?

If the new value is smaller than the original, you have a percentage decrease instead of an increase. Use our Percentage Decrease Calculator for this scenario.

Can percentage increase be more than 100%?

Yes! A percentage increase over 100% means the value has more than doubled. For example, going from 100 to 300 is a 200% increase.

What does a 100% increase mean?

A 100% increase means the value has doubled. The new value is exactly twice the original value.
