# Percentage Increase Calculator

Calculate the percentage increase or decrease for given values.

To calculate the percentage increase the 1st we calculate the difference (increase) between the two entered values

Increase = Increased value - Original value and then divide the increase by the original number and multiply by 100.

% increase = Increase ÷ Original value × 100

In case Percentage Increase shows a negative value then this is a percentage decrease.

### Example

**1. Find the percentage increase, if the original value is 1000 and the increase value is 1055.**

Percentage Increase = [(1055 - 1000) ×100]/1000

= 5500/1000

= 5.5%

The percentage increase is 5.5%

**2. Find the percentage increase, if the original value is 780 and the increase value is 705.**

Percentage Increase = [(705 - 780) ×100]/780

= -7500/780

= -9.615%

The percentage increase is -9.615% means there is a **decrease of 9.615%**
