🤔 How Does This Tool Work?

Our Percentage Calculator handles three types of percentage calculations:

  • What is X% of Y? → Answer = Y × X ÷ 100. Used for: discounts, tips, tax calculations.
  • X is what % of Y? → Answer = X ÷ Y × 100. Used for: exam scores, completion rates, progress tracking.
  • Percentage change → Answer = (New−Old) ÷ Old × 100. Used for: salary increases, price changes, growth rates.

Each calculation shows the result with a clear explanation of what the number means, so you always understand what you are looking at.

❓ FAQ
How do I calculate 20% of a number?▼
Multiply the number by 20 then divide by 100. Example: 20% of 500 = 500 × 20 ÷ 100 = 100. Or just enter 20 in the percentage field and 500 in the number field and click Calculate!
How do I find what percentage one number is of another?▼
Divide the first number by the second, then multiply by 100. Example: 45 is what % of 180? Answer: 45 ÷ 180 × 100 = 25%. Select 'X is what % of Y?' in the calculator above.
How do I calculate a percentage increase?▼
Formula: ((New Value − Old Value) ÷ Old Value) × 100. Example: price went from 200 to 250 = ((250−200) ÷ 200) × 100 = 25% increase. Select 'Percentage increase/decrease' above.
What is the quickest way to calculate 10% of a number?▼
Move the decimal point one place to the left! 10% of 350 = 35. 10% of 4,800 = 480. Then you can easily find 5% (half of 10%), 20% (double 10%), or 15% (10% + 5%).
How do I calculate a discount price?▼
Find the discount amount: Original Price × Discount% ÷ 100. Then subtract from original: Original − Discount = Sale Price. Example: 2,000 with 25% off = 2,000 × 25 ÷ 100 = 500 discount. Sale price = 1,500.
