Stack sale discounts, coupons, cashback and tax to find the true final price — and compare two offers side by side. Free deal calculator.
Here's the trick retailers count on: discounts stack sequentially, not additively. "20% off, plus an extra 10% off" is not 30% off — it's 28% off, because the second 10% comes off the already-reduced price. Then there's the coupon, the cashback that arrives weeks later, and the tax that quietly climbs back on. This calculator applies every layer in the real order and shows the price you'll actually pay — for two competing offers side by side, so the better deal can't hide.
A smaller headline discount with a fat coupon and cashback often beats a big flashy percentage. The verdict below calls the winner by final price — but if the gap is tiny, the seller with free returns or faster shipping is still the smarter buy. Price is the biggest factor, not the only one.
No — they apply one after another. 20% off $100 leaves $80, then 10% off $80 leaves $72. That's 28% off total, not 30%. The calculator applies them in the correct sequential order.
Not quite. A discount lowers what you pay today; cashback returns money later (and sometimes as store credit). The calculator subtracts it last so you see both the checkout price and the true final cost.
Because retailers frame deals to look unbeatable. Putting two offers through the same math — discounts, coupon, tax, cashback — exposes which one is genuinely cheaper instead of which one advertises better.
