What you'll actually pay at the register
Enter the price and discount — plus an optional extra coupon and your sales tax — and see the final price, the dollars saved, and the true combined discount percentage. The stacked-discount math is where stores count on you estimating wrong.
Frequently asked questions
How do stacked discounts work?
They apply one after another, not added together: 25% off then an extra 20% off is 40% total, not 45% — the second discount applies to the already-reduced price. The calculator shows your true effective discount.
Is tax applied before or after the discount?
After, which is how stores do it: you pay tax on the discounted price, not the original.
How do I quickly estimate a discount mentally?
10% is just the price with the decimal moved left; build from there (25% = 10% + 10% + half of 10%). Or skip the mental math — this page loads fast on a phone in a store aisle.
