Enter the original price and stack as many percentage or fixed-amount discounts as you need. Add sales tax and instantly see the final price and your total savings, with a visual price comparison.
Each discount row is applied one after another to the running price — not all at once off the original price. For example, 20% off followed by an extra 10% off means the second discount applies to the already-reduced price, which is why stacked percentage discounts add up to less than their sum.
Fixed-amount discounts (like a $10 coupon) simply subtract that dollar value from the running price at the point they're applied. Sales tax, when entered, is calculated on the final discounted price, matching how most checkout systems calculate tax after coupons.
Final price = original price × (1 − discount percentage ÷ 100).
Amount saved = original price × (discount percentage ÷ 100), or simply original price minus final price.
Each discount applies to the price remaining after the previous one, so two 10% discounts stacked equal a 19% total discount, not 20%.
