This calculator combines mathematical accuracy with user-friendly interface design, making percentage calculations accessible to students, professionals, accountants, shoppers, investors, and anyone needing quick, reliable percentage computations.

How It Works

Five Specialized Calculation Modes

1. Basic Mode – Four essential calculations: “What is X% of Y?”, “X is what percent of Y?”, “Percentage Change”, “X is Y% of what?”
2. Advanced Mode – Complex operations: “Value After Percentage Increase”, “Value After Percentage Decrease”, “Percentage Difference”, “Chain Percentages” (multiple sequential operations)
3. Visual Mode – Graphical representations: Pie charts showing percentage distribution, percentage-to-decimal conversion, percentage visualization for comparison values
4. Batch Mode – Bulk processing: Apply same percentage operation (increase/decrease/of) to multiple values simultaneously, perfect for processing large datasets
5. Formulas Tab – Reference guide: All percentage formulas displayed with working examples and step-by-step calculations

Technical Details

Core Percentage Formulas

• What is X% of Y? Formula: (Result = \frac{X}{100} \times Y)
  Example: What is 20% of 150? (\frac{20}{100} \times 150 = 30)
• X is what percent of Y? Formula: (Result = \frac{X}{Y} \times 100)
  Example: 30 is what percent of 150? (\frac{30}{150} \times 100 = 20%)
• Percentage Change Formula: (Result = \frac{(New – Old)}{Old} \times 100)
  Example: Change from 50 to 75? (\frac{75-50}{50} \times 100 = 50%) increase
• X is Y% of what? Formula: (Result = \frac{X}{(Y/100)})
  Example: 30 is 20% of what? (\frac{30}{(20/100)} = 150)
• Value After X% Increase Formula: (Result = Original \times (1 + \frac{X}{100}))
  Example: 100 increased by 10%? (100 \times (1 + 0.10) = 110)
• Value After X% Decrease Formula: (Result = Original \times (1 – \frac{X}{100}))
  Example: 100 decreased by 10%? (100 \times (1 – 0.10) = 90)
• Percentage Difference Formula: (Result = \frac{|A – B|}{\frac{(A+B)}{2}} \times 100)
  Example: Difference between 50 and 75? (\frac{25}{62.5} \times 100 = 40%)
