Percentage Formula
Percentage Calculation Formula
The basic formula for calculating a percentage of a number is:
Percentage Amount = Original Amount × (Percentage ÷ 100)
For an increase, add the percentage amount to the original amount. For a decrease, subtract the percentage amount from the original amount.
This formula works for any percentage calculation involving money, whether you're calculating discounts, sales tax, tips, or interest.
Worked Examples
Example 1: Calculating a 20% Discount
If an item costs $100 and you want to calculate a 20% discount:
- Original Amount = $100
- Percentage = 20%
- Percentage Amount = $100 × (20 ÷ 100) = $20
- Final Amount = $100 - $20 = $80
The discount amount is $20, and the final price after the discount is $80.
Example 2: Calculating a 15% Increase
If your salary is $5,000 and you receive a 15% raise:
- Original Amount = $5,000
- Percentage = 15%
- Percentage Amount = $5,000 × (15 ÷ 100) = $750
- Final Amount = $5,000 + $750 = $5,750
The raise amount is $750, and your new salary is $5,750.
