How to Calculate Percent Increase

The Basic Formula

Percentage Increase = (New Value - Original Value) / Original Value × 100%

Example: If a product’s price rises from $50 to $60:

Difference: $60 - $50 = $10
Calculation: (10/50) × 100% = 20%

Thus, there is a 20% increase.

Calculating Percent Decrease

Percentage Decrease = (Original Value - New Value) / Original Value × 100%

Example: If a stock drops from $100 to $80:

Difference: $100 - $80 = $20
Calculation: (20/100) × 100% = 20%

So, there is a 20% decrease.

Adding a Percentage Increase to a Number

Convert the percentage to a decimal and multiply it with the original number, then add the result back.

Example: Adding 5%

Original Number: 100
Calculation: 100 × (1 + 0.05) = 105

Thus, 100 increased by 5% is 105.
