How do I combine two discounts?

Apply the larger discount first, then enter the resulting sale price with the second discount. They never simply add.

Is tax applied before or after discount?

Almost everywhere, sales tax applies to the price actually charged; after discounts, before coupons that behave like cash.

What is the discount in dollars?

Good to know

Reading discount claims critically

Retailers sometimes inflate a “was” price before applying the slash. Tracking genuine historical prices beats trusting strikethroughs. A discount on something you did not plan to buy is still a 100% markup on zero.

Stacking rules

Successive percentages multiply: 30% then 20% off leaves 0.7 × 0.8 = 56% of the original price. Stores love quoting “50% total savings!” when the true stack is far less.

How it's calculated

The math behind this calculator

Sale price = Price × (1 − discount% / 100)

Multiply the original price by the surviving fraction after the discount. Stacked discounts (e.g. “extra 20% off already 30% off”) apply sequentially, not additively; chain this calculator twice for those cases.

Assumptions & limitations

Single discount applied to the listed price.
Tax is calculated on the discounted price in most jurisdictions.
“50% + extra 20% off” equals 60% total off, not 70%.

Worked example

A $129.99 item at 25% off sells for $97.49, putting $32.50 back in your pocket.
