Discount & Retail Markup Calculation: Merchant & Shopper Guide
Last updated: 2026-09-11 • Editorial Staff
Understanding discount and markup calculations is crucial for both consumers evaluating store sales and merchants pricing inventory.
While a discount reduces the original list price by a percentage, a markup increases cost price to determine final retail selling price and target profit margins.
How Sale Discounts Are Computed
Discount Amount = Original Retail Price × (Discount Rate ÷ 100)
Final Discounted Price = Original Retail Price - Discount Amount
Example: A jacket listed at $120 with a 25% promotional discount saves $30, resulting in a final checkout price of $90.
Markup vs Profit Margin
Markup Percent = [(Selling Price - Cost Price) ÷ Cost Price] × 100
Profit Margin Percent = [(Selling Price - Cost Price) ÷ Selling Price] × 100
Because markup is calculated relative to cost while margin is calculated relative to sales revenue, markup percentage is always higher than profit margin percentage for the same dollar profit.
