1. What is the Discount To Original Price Formula?

The Discount To Original Price formula calculates the original price of an item before a discount was applied, given the sale price and discount rate. This is useful for understanding the true value of discounted items and comparing prices.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Sale \) — The discounted sale price (currency)
• \( Discount \) — The discount rate expressed as a decimal (unitless)

Explanation: The 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 discounted items, compare prices across different retailers, and make informed purchasing decisions.

4. Using the Calculator

Tips: Enter the sale price in currency format and the discount rate as a decimal (e.g., 0.20 for 20% off). Both values must be valid (sale price > 0, discount between 0-0.99).

5. Frequently Asked Questions (FAQ)

Q1: Why use this formula instead of simple percentage calculations?
A: This formula accurately reverses the discount calculation to find the original price, which is different from calculating a percentage of the sale price.

Q2: What if the discount is 100% (free item)?
A: The formula cannot calculate the original price when discount is 1 (100%) because division by zero occurs. This represents a mathematical limitation.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise when the discount was applied correctly to the original price.

Q4: Can this be used for multiple discounts?
A: This formula calculates the original price before a single discount. For multiple successive discounts, a more complex calculation is needed.

Q5: Does this work for percentage increases as well?
A: No, this formula is specifically designed for discount calculations. For price increases, a different formula would be required.
