To Calculate Percentage Increase or Decrease :

$\text{Percentage Increase or Decrease} = \frac{\text{New Value} – \text{Old Value}}{\text{Old Value}} \times 100$

To Determine What Percentage One Number Is of Another : 

$\text{Percentage} = \frac{\text{Part}}{\text{Whole}} \times 100$

Interpret Results:

Example Calculations

Example 1 : Finding Percentage of a Total Amount

Percentage : 25%
Total Amount : $200

Example 2 : Calculating Percentage Increase

Old Value : $150
New Value : $180
Calculation :




$\text{Percentage Increase} = \frac{180 – 150}{150} \times 100 = 20\%$


Example 3 : Finding What Percent One Number Is of Another

Part : 30
Whole : 120

Calculation :


$\text{Percentage} = \frac{30}{120} \times 100 = 25\%$
