1. What is Percentage Off Calculator?

The Percentage Off Calculator helps you determine the final price after a discount and the amount you save. It's useful for shopping, sales, and financial planning.

2. How Does the Calculator Work?

The calculator uses the discount formula:

Where:

• \( Original \) — Original price before discount
• \( \% \) — Percentage discount (0-100)

Explanation: The formula calculates the remaining percentage you pay after the discount is applied.

3. Importance of Discount Calculation

Details: Understanding discounts helps with budgeting, comparing deals, and making informed purchasing decisions.

4. Using the Calculator

Tips: Enter the original price in USD and the discount percentage (0-100). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Can I calculate multiple discounts?
A: For multiple discounts, apply them sequentially (not by adding percentages together).

Q2: What's the difference between percentage off and percentage of?
A: "Percentage off" subtracts from the original, while "percentage of" calculates a portion (e.g., 20% off $100 = $80; 20% of $100 = $20).

Q3: How do I calculate the original price from a discounted price?
A: Original = Discounted / (1 - %/100). For example, if you paid $80 after 20% off: $80 / 0.8 = $100.

Q4: Does this work for percentage increases?
A: For increases, use the formula: New = Original × (1 + %/100).

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but always verify final prices as some stores may round differently.
