Discount Calculator
Work out a sale price in seconds. Enter the original price and the percent off to see what you'll pay and what you save. Add a second coupon to see how stacked discounts really combine — 20% then 10% off is 28% off, not 30%.
A second discount applied to the already-reduced price.

How this calculator works
Sale price = original × (1 − discount). A second coupon is applied to that reduced price, so the two discounts compound rather than sum. The effective discount is total savings divided by the original price.
This is the price math only — it doesn't add sales tax, which is applied to the discounted price at checkout. Use the Sales Tax calculator to see the final out-the-door total.

Frequently asked questions
How do I calculate a discount?
Multiply the original price by the discount percentage to get the amount off, then subtract it. A 25% discount on $80 is $80 × 0.25 = $20 off, so you pay $60. This calculator does both steps and shows the savings and the price you'll actually pay.
Do stacked discounts add together?
No — they multiply. An extra 10% off an item already 20% off isn't 30% off. The first cut takes $100 to $80, then 10% off $80 is $8, so you pay $72 — a 28% effective discount. Stacked coupons always save a little less than the two percentages added together.
How do I find the original price from a sale price?
Divide the sale price by (1 minus the discount). If an item is $60 after 25% off, the original was $60 ÷ 0.75 = $80. Reversing a discount this way is handy for checking whether a 'sale' price is really a deal.
