Whether you are a consumer trying to maximize savings during a holiday sale or a retailer pricing clearance inventory, computing the exact mathematical impact of a percentage-based discount is a practical necessity. Accurately determining the final price prevents budgeting errors at the checkout counter and ensures businesses maintain correct accounting records when logging reduced-price revenue.

Frequently Asked Questions (FAQ)
How do I stack multiple discounts?
When a store offers "20% off, plus an additional 10% off," you do NOT add the percentages together to get 30%. You must apply the first discount to the original price, and then apply the second discount to the new, reduced subtotal. This sequential calculation always results in slightly lower savings than a flat combined percentage.
How do I find the original price if I only know the final price?
To reverse-calculate a discount, divide the final sale price by the difference between 1 and the discount rate. For example, if you bought an item for $80 after a 20% discount, divide $80 by 0.80 (which is 1 - 0.20) to find the original $100 price.
