What is a percentage increase?
A percentage increase measures how much a value has grown compared with its original amount. It is commonly used for salary increases, price changes, sales growth, population growth, investments, and many other everyday calculations.
For example, if a product price increases from $80 to $100, the percentage increase is 25%.
Percentage increase formula
Percentage Increase = ((New Value − Original Value) ÷ Original Value) × 100
Where:
- Original Value = the starting amount
- New Value = the ending amount
How to calculate percentage increase
Follow these steps:
- Subtract the original value from the new value.
- Divide the increase by the original value.
- Multiply the result by 100.
- Add the percent sign (%).
Example 1: salary increase
Original salary: $2,000
New salary: $2,300
Increase = $2,300 − $2,000 = $300
Percentage increase = ($300 ÷ $2,000) × 100 = 15%
The salary increased by 15%.
Example 2: price increase
Original price: $50
New price: $65
Increase = $15
Percentage increase = ($15 ÷ $50) × 100 = 30%
The price increased by 30%.

Percentage increase vs. percentage decrease
A percentage increase occurs when the new value is greater than the original value.
A percentage decrease occurs when the new value is smaller than the original value.
For example:
- $100 to $120 = 20% increase
- $120 to $100 = 16.67% decrease
Notice that percentage increase and percentage decrease are not symmetrical because they use different starting values.
