Understanding Percent Off & Double Discounts

A percent off discount is a proportional markdown on an item's original retail value. Understanding how single and stackable discounts work prevents shopping math errors.

1. Single Markdown Calculation

To find the sale price of an item:

Final = Price × (1 - Rate / 100)

For example, 20% off $279 gives: $279 × 0.80 = $223.20 (savings of $55.80).

2. Stackable / Double Discounts

Stores often offer "an extra 15% off clearance (already 20% off)". These discounts are sequential, not additive:

Final = Price × (1 - 0.20) × (1 - 0.15)

The effective total discount is 32%, not 35% (0.80 × 0.85 = 0.68).

3. Reverse Solving

If you know the final sale price ($33.99) and the dollar savings ($6.00), you can determine the original price ($39.99) and the percentage markdown (15.00%).
