1. What is the Original Price Formula?

The Original Price Formula calculates the original price of an item before a discount was applied, based on the sale price and discount rate. This is useful for understanding the true value of discounted items.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Sale \) — The discounted price (currency)
• \( Discount\ Rate \) — The discount rate as a decimal (e.g., 0.20 for 20%)

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 discounts, compare deals between retailers, and make informed purchasing decisions.

4. Using the Calculator

Tips: Enter the sale price in dollars and the discount rate as a decimal (e.g., 0.25 for 25% off). Both values must be valid (sale price > 0, discount rate between 0-0.99).

5. Frequently Asked Questions (FAQ)

Q1: Why calculate the original price?
A: Knowing the original price helps you understand the true value of a discount and compare deals more effectively.

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

Q3: Can this formula be used for multiple discounts?
A: This formula calculates the original price after a single discount. For multiple discounts, you would need to apply the formula sequentially.

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: Does this work for all currencies?
A: Yes, the formula works for any currency as long as you're consistent with the currency units.
