What is a Percentage and How is it Calculated?

A percentage is a way of expressing a number as a fraction of 100. For example, 25% means 25 out of every 100. Percentages are used widely in daily life: calculating discounts while shopping, determining profit margins in business, computing taxes, and understanding salary or price increases.

How to Calculate Percentages

1. Finding a Percentage of a Number

To find the value of a specific percentage of any number, multiply the number by the percentage and divide by 100:

Result = Number × Percentage ÷ 100

Example: What is 15% of 800? → Result = 800 × 15 ÷ 100 = 120

2. Percentage Difference Between Two Numbers

To find the percentage change between an old value and a new value:

Change % = (New - Old) ÷ Old × 100

Example: Salary changed from 5,000 to 5,750 → Increase = (5750 - 5000) ÷ 5000 × 100 = 15%

3. Increase or Discount by Percentage

To add a percentage (like a price increase) or subtract one (like a discount):

After Increase = Number × (1 + Percentage ÷ 100)
After Discount = Number × (1 - Percentage ÷ 100)

Example: 30% discount on SAR 200 → 200 × (1 - 30÷100) = 200 × 0.70 = SAR 140

Business Uses for Percentages

  • Profit Margins: Know your profit percentage on every sale
  • Discounts: Determine the final price after markdowns
  • Growth Analysis: Compare revenue across periods to find growth rates
  • Commissions: Calculate commission amounts based on a percentage of sales
  • Salary Adjustments: Compute annual raises or bonus amounts
  • Tax Calculations: Such as the 15% VAT in Saudi Arabia

Subtract the old number from the new, divide by the old, and multiply by 100. Example: from 200 to 260, difference = (260-200) ÷ 200 × 100 = 30% increase. If the new number is smaller, the result will be negative (decrease).
