Percentage Calculator

Calculate percentages, percentage increases, and percentage decreases. Useful for discounts, tips, taxes, and more.

How Percentage Calculator Works

This calculator performs three common percentage operations:

  • X% of Y: Calculates what percentage X is of value Y (e.g., 20% of 100 = 20)
  • X increased by Y%: Adds Y% to X (e.g., 100 increased by 20% = 120)
  • X decreased by Y%: Subtracts Y% from X (e.g., 100 decreased by 20% = 80)

Common Uses

Discounts: Calculate sale prices (e.g., 50 with 25% off = 37.50)

Tips: Calculate tip amounts (e.g., 100 bill with 18% tip = 18)

Taxes: Calculate tax amounts (e.g., 100 with 8% tax = 8)

Growth: Calculate increases (e.g., 1,000 increased by 5% = 1,050)

Examples

Example 1: What is 15% of 200?

Result: 30 (15% of 200 = 30)

Example 2: 80 increased by 25%

Result: 100 (80 + 20 = 100)

Example 3: 150 decreased by 30%

Result: 105 (150 - 45 = 105)
