What is a Discount? Types of Discounts

A discount is a reduction from the original price of a product or service, used for promotions, clearance sales, or customer incentives.

Common Discount Types:

  • Percentage Discount: Fixed percentage off (e.g., 20% off)
  • Fixed Amount: Dollar amount reduction (e.g., $10 off)
  • Stacked Discounts: Multiple discounts applied sequentially
  • Bulk Discounts: Better prices for larger quantities
  • BOGO: Buy one, get one (50% effective discount)

Formula: Sale Price = Original Price × (1 - Discount Rate)

How to Calculate Discounts Manually

Step-by-Step Process:

  1. Percentage Discount: Original Price × Discount% = Savings
  2. Subtract Savings: Original Price - Savings = Sale Price
  3. Stacked Discounts: Apply first discount, then second to result
  4. Calculate Total: Sale Price × Quantity = Total Cost

Example: $100 item with 20% off then $5 coupon:
$100 × 0.8 = $80, then $80 - $5 = $75 final price

Quick Tips:

  • Compare percentage vs. fixed discounts to find the better deal
  • Order matters: "30% off then $10 off" ≠ "$10 off then 30% off"
  • Calculate unit price for bulk purchases
