What is Percentage Increase?
A percentage increase represents a growth or rise in value expressed as a percentage of the original amount. It shows how much larger the new value is compared to the original value.
When something increases by a percentage, you multiply the original value by (1 + percentage/100) to find the new value. For example, a 20% increase means multiplying by 1.2 (1 + 20/100).
How to Calculate Percentage Increase
To calculate a value after a percentage increase:
Multiplier = 1 + (Percentage ÷ 100)
New Value = Original Value × Multiplier
For example, to calculate a 25% increase from 100:
- Calculate the multiplier: 1 + (25 ÷ 100) = 1.25
- Multiply the original value: 100 × 1.25 = 125
- The absolute increase is: 125 - 100 = 25
