Know the real price before you buy
Sale tags show a percentage off, but the number that matters is what you actually pay. Enter the original price and the discount and this calculator shows the final price and your savings instantly. Add a second coupon to model 'extra 10% off sale items', and include sales tax to see the true checkout total.
Handy for shoppers and sellers
Shoppers can compare deals and check whether a coupon is worth it; sellers can price promotions and confirm margins still hold. The quick-percent buttons make common discounts one tap away. Everything is calculated in your browser — nothing is uploaded.
