Discount Calculator

Multiply the original price by the discount rate divided by 100 to get the dollars saved, then subtract that from the original. A 25% discount on $80 saves $20, leaving a sale price of $60. The % off → sale price tab does this in one step.

Take the original price minus the sale price (your savings), divide by the original price, then multiply by 100. $200 down to $140 is $60 saved, divided by $200 = 0.30, so 30% off. The What % off? tab handles this without the math.

After. US sales tax is calculated on the discounted price you actually pay — that's the post-discount subtotal. Coupons, store discounts, and percentage-off promotions reduce the taxable amount; manufacturer rebates that come back to you later usually don't. Most states follow this rule, with a few exceptions for specific coupon types — check your state department of revenue if you need certainty.

No, and shoppers regularly overestimate the saving. '30% off, plus an extra 20% off at checkout' is not 50% off — it's 30% off the original, then 20% off the discounted price, which is 44% off the original. Each discount works on the running total, so stacking always saves less than the percentages added together.

A discount is taken at the register from the marked price (the price tag still says $80 but you pay $60). A markdown is when the price tag itself is reduced — the new lower price is what's posted. Mathematically the calculator works the same way for both; the distinction is mainly retail accounting language.
