1. What is the Discount Calculator?

The Discount Calculator computes the final price after applying a percentage discount to an original price. It's useful for shoppers, retailers, and financial calculations.

2. How Does the Calculator Work?

The calculator uses the discount formula:

Where:

• Original — Original price before discount (USD)
• Discount % — Discount percentage expressed as decimal (e.g., 0.20 for 20%)

Explanation: The formula subtracts the discount amount (original price multiplied by discount percentage) from the original price.

3. Importance of Discount Calculation

Details: Accurate discount calculation helps consumers understand savings, businesses set profitable pricing strategies, and financial analysts evaluate promotions.

4. Using the Calculator

Tips: Enter original price in USD and discount as a decimal (e.g., 0.15 for 15%). Both values must be valid (price > 0, discount between 0-1).
