Understanding the Basics: Key Percentage Formulas

Before diving into the calculator, let's brush up on some fundamental percentage formulas:

• Percentage of a Number: To find a percentage of a number, multiply the number by the percentage (expressed as a decimal).
  • Formula: (Percentage / 100) * Number
  • Example: What is 20% of 150? (20 / 100) * 150 = 30
• Percentage Increase: To calculate the percentage increase between two numbers, divide the difference by the original number and multiply by 100.
  • Formula: [(New Value - Original Value) / Original Value] * 100
  • Example: A price increased from $50 to $60. What is the percentage increase? [(60 - 50) / 50] * 100 = 20%
• Percentage Decrease: Similar to percentage increase, but subtract the new value from the original value.
  • Formula: [(Original Value - New Value) / Original Value] * 100
  • Example: A price decreased from $100 to $75. What is the percentage decrease? [(100 - 75) / 100] * 100 = 25%
• Finding the Original Value: If you know the final value and the percentage increase or decrease, you can find the original value.
  • Formula (Increase): Final Value / (1 + Percentage / 100)
  • Formula (Decrease): Final Value / (1 - Percentage / 100)
  • Example (Increase): A value increased by 10% and is now $110. What was the original value? 110 / (1 + 10 / 100) = $100
  • Example (Decrease): A value decreased by 20% and is now $80. What was the original value? 80 / (1 - 20 / 100) = $100

Real-World Applications of the Percentage Calculator: Practical Examples

• Retail and Shopping:
  • Discounts: Imagine a shirt originally priced at R$150 is on sale for 25% off. Use the calculator to find the discount amount (R$37.50) and the final price (R$112.50).

  • Comparing Prices: A store offers a 30% discount on an item, while another offers R$50 off. If the original price is R$200, use the calculator to determine which offer is better (30% off is R$140, R$50 off is R$150).
