In this guide, we’ll explain what percentage increase is, how to calculate it, and why using a percentage increase calculator makes things easier, with clear examples you can follow.
What Is Percentage Increase?
A percentage increase shows how much a value has gone up compared to its original amount, expressed as a percentage.
In simple terms, it answers the question:
“By what percent did this number increase?”
For example:
- Your salary goes from $500 to $600
- A product price increases from $40 to $50
- Website traffic grows from 1,000 to 1,250 visitors
All these situations involve a percentage increase.
Percentage Increase Formula
The standard formula to calculate percentage increase is:
Percentage Increase = ((New Value − Original Value) ÷ Original Value) × 100
This formula works for all types of numbers, whether they relate to money, marks, population, or performance metrics.
How to Calculate Percentage Increase
- Subtract the starting value from the final value.
- Divide the result by the absolute value of the starting value.
- Multiply the answer by 100 to convert it into a percentage.
- If the final percentage is negative, it indicates a decrease rather than an increase.
Example 1: Salary Increase
- Original salary: $800
- New salary: $1,000
Step 1: Find the difference
$1,000 − $800 = $200
Step 2: Divide by the original value
$200 ÷ $800 = 0.25
Step 3: Multiply by 100
0.25 × 100 = 25%
✅ Your salary increased by 25%
Example 2: Price Increase
- Original price: $60
- New price: $75
Difference: $15
$15 ÷ $60 = 0.25
0.25 × 100 = 25%
The price increased by 25%
