How do stacked coupons apply?

Additional coupons apply after the primary discount is deducted from the original price.

Is 20% off plus 10% off the same as 30% off?

No. The second discount applies to the reduced price, so the total saving is 28%.

Is tax applied before or after discounts?

After. This calculator applies tax to the discounted subtotal.

How do I find the discount percentage from two prices?

Use the Percentage Calculator's change card: enter the original and sale price to see the percentage decrease.

Can I leave sales tax at zero?

Yes. Set tax to 0 for countries where prices already include tax.

How stacked discounts work

A coupon applied after a sale discount is taken off the already-reduced price, not the original. 20% off and then an extra 10% off a $100 item gives $72, not $70, which is a total saving of 28%, not 30%.

Sales tax is calculated on the price after all discounts, which is how most US stores charge it.

Reading the breakdown

The breakdown shows each step: original price, discount, coupon, subtotal, and tax, so you can check a receipt line by line. The You pay total includes tax, and You save shows the combined value of the discount and coupon.

Sales tax rates vary by state and city. Use the rate on a recent receipt for the most accurate total.
