Frequently Asked Questions

How do I calculate a percentage discount? ▼

To calculate a percentage discount, use this formula:

Final Price = Original Price × (1 - Discount% / 100)

Example: A $100 item with 20% off:

Final Price = 100 × (1 - 20/100) = 100 × 0.8 = $80
What is the difference between percent off and fixed amount off? ▼

Percent Off: A percentage reduction of the original price. The savings amount varies based on the original price.

Example: 20% off $100 = $20 savings, but 20% off $50 = $10 savings

Fixed Amount Off: A specific dollar amount subtracted from the price, regardless of original price.

Example: $10 off any price means exactly $10 savings whether item costs $100 or $50
How do I calculate the discount percentage from a sale price? ▼

If you know the original and sale price, calculate the discount percentage:

Discount% = ((Original Price - Sale Price) / Original Price) × 100

Example: Original $100, Sale Price $75:

Discount% = ((100 - 75) / 100) × 100 = 25%
How do I calculate savings from a discount? ▼

Savings is the difference between the original price and final price:

Savings = Original Price - Final Price

Example:

Original: $59.99, Final: $50.99
Savings = 59.99 - 50.99 = $9.00
How do multiple discounts work? ▼

Multiple discounts are applied sequentially (one after another), NOT added together. This is called "stacking" discounts.

Example: 20% off, then 10% off on a $100 item:

Step 1: 20% off = $100 × 0.8 = $80
Step 2: 10% off $80 = $80 × 0.9 = $72
Total savings: $28 (not 30%!)
What's the relationship between markup and discount? ▼

Markup adds a percentage to cost to set a selling price. Discount reduces a price for a buyer. They're inverse concepts:

  • Markup: Seller adds percentage to cost
  • Discount: Seller reduces price for buyer
  • Formula relationship: A 20% discount is not the same as a 20% markup
