1. What is the Discount Formula?

The discount formula calculates the final price after applying a percentage reduction to the original price. It's commonly used in retail, sales, and financial calculations.

2. How Does the Calculator Work?

The calculator uses the discount formula:

Where:

• \( \text{Original} \) — Original price before discount (USD)
• \( \% \) — Discount percentage (0-100%)

Explanation: The formula calculates the reduced price by subtracting the discount percentage from 100%, then multiplying by the original price.

3. Importance of Discount Calculation

Details: Accurate discount calculation is crucial for pricing strategies, customer promotions, budgeting, and financial planning in both business and personal finance.

4. Using the Calculator

Tips: Enter the original price in USD and the discount percentage (0-100). All values must be valid (price > 0, percentage between 0-100).

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate multiple discounts?
A: For multiple discounts, apply them sequentially. For example, 20% then 10% is not the same as 30% off.

Q2: How do I calculate the original price from discounted price?
A: Original = Discounted / (1 - %/100). This calculator doesn't perform this reverse calculation.

Q3: What's the difference between discount percentage and discount amount?
A: Percentage is relative to original price, while amount is fixed (e.g., $10 off vs 10% off).

Q4: Does this work for price increases (negative discount)?
A: Mathematically yes, but the calculator restricts to 0-100% range for typical use cases.

Q5: How precise are the calculations?
A: Results are rounded to 2 decimal places (cents) for currency display.
