Pro Tip
Before buying during a sale, check the price history. Some retailers raise prices before a sale to make discounts seem larger. Use price tracking tools to verify you are getting a genuine deal.

Discounts reduce the price of goods or services by a percentage or fixed amount. Understanding how to calculate discounts helps you make informed purchasing decisions and compare deals across different retailers. Sales tax is typically calculated on the discounted price, not the original price.
When comparing deals, look at the actual dollar savings, not just the percentage. A 50% discount on a $20 item saves $10, while a 20% discount on a $200 item saves $40. The larger percentage does not always mean the bigger savings.
Stacked discounts (e.g., 20% off plus an additional 10% off) are not the same as a single combined discount. A 20% discount followed by 10% off results in a 28% total discount, not 30%. This is because the second discount applies to the already-reduced price.
Discount Calculation
Where:
Discount = Original Price x (Discount % / 100)
Tax Rate = Local sales tax rate as a decimal
Example
$120 item with 25% discount and 8.25% tax:
- • Discount amount: $120 x 25% = $30.00
- • Discounted price: $120 - $30 = $90.00
- • Tax on discounted price: $90 x 8.25% = $7.43
- • Final price: $90 + $7.43 = $97.43
- • Total savings vs full price + tax: $32.47
