1. What is the Original Price Calculator?

The Original Price Calculator determines the original price of an item before a discount was applied, using the sale price and discount rate. This is particularly useful for price comparisons and understanding the true value of discounted items.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Sale Price — The discounted price of the item (£)
• Discount Rate — The discount rate as a decimal (e.g., 0.20 for 20%)

Explanation: This formula reverses the discount calculation to find the original price before the discount was applied.

3. Importance of Original Price Calculation

Details: Calculating the original price helps consumers understand the true value of discounts, compare prices across different retailers, and make informed purchasing decisions.

4. Using the Calculator

Tips: Enter the sale price in pounds (£) and the discount rate as a decimal (e.g., 0.15 for 15% discount). Both values must be valid (sale price > 0, discount rate between 0-0.99).

5. Frequently Asked Questions (FAQ)

Q1: Why calculate original price instead of just using sale price?
A: Knowing the original price helps you understand the true discount value and compare deals across different retailers more effectively.

Q2: How do I convert percentage discount to decimal?
A: Divide the percentage by 100. For example, 25% discount becomes 0.25, 15% becomes 0.15.

Q3: Can this calculator handle multiple discounts?
A: This calculator is designed for single discounts. For multiple successive discounts, a different calculation method is required.

Q4: What if the discount rate is 0%?
A: If discount rate is 0, the original price equals the sale price, as no discount was applied.

Q5: Is this calculation accurate for all types of discounts?
A: This calculation works for simple percentage discounts. It may not apply to complex discount structures or bundled offers.
