What is Percent Increase?

Percent increase shows how much something has grown from its original value, expressed as a percentage. It's commonly used to understand price hikes, population growth, salary raises, and other increases in value.

Percent Increase Formula

Percent Increase = (New Value - Original Value) ÷ Original Value × 100%

Example:

• Original price: $50
• New price: $75
• Percent increase = ($75 - $50) ÷ $50 × 100 = 50%

How to Calculate Percent Increase

1. Subtract the original value from the new value
2. Divide by the original value
3. Multiply by 100 to get the percentage

Examples of Percent Increase Calculations

Example 1: Salary Raise

Original salary: $40,000
New salary: $46,000
Percent increase = ($46,000 - $40,000) ÷ $40,000 × 100 = 15%

Example 2: Store Prices

Original price: $20
New price: $25
Percent increase = ($25 - $20) ÷ $20 × 100 = 25%
