1. What is a 20% Discount Calculator?

The 20% Discount Calculator quickly calculates the reduced price of an item after applying a 20% discount. It's particularly useful for shoppers in the UK to determine final prices during sales and promotions.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• \( Original\ Price \) — The initial price before discount
• \( 0.8 \) — Represents 80% of the original price (100% - 20% discount)

Explanation: A 20% discount means you pay only 80% of the original price. The calculator multiplies the original price by 0.8 to find the discounted amount.

3. Importance of Discount Calculation

Details: Understanding discount calculations helps consumers make informed purchasing decisions, compare deals effectively, and manage personal budgets more efficiently.
