1. What is the Discount Calculator?

The Discount Calculator calculates the final price of an item after applying a discount percentage. It helps shoppers and businesses determine sale prices quickly and accurately.

2. How Does the Calculator Work?

The calculator uses the discount formula:

Where:

• \( P \) — Original price (₹ or currency)
• \( d \) — Discount rate (decimal)

Explanation: The formula subtracts the discount amount from the original price to calculate the final discounted price.

3. Importance of Discount Calculation

Details: Accurate discount calculation is essential for pricing strategies, budgeting, and making informed purchasing decisions in both personal shopping and business operations.
