Discounts and Final Price: A Complete Guide
A discount reduces the original price by a percentage or fixed amount. The real checkout cost may also include tax, quantity, coupon restrictions, shipping, or store-specific rules.
This calculator focuses on the main pricing pieces: original price, percentage discount, fixed coupon, quantity, and tax after discount. It shows sale price per item, total savings, tax amount, and final total.
Original price
The original price is the starting point. When quantity is more than one, the calculator multiplies the price by quantity before summarizing savings and final cost.
Percentage discount
A percentage discount removes a portion of the original price. For example, 25% off means the discounted price is 75% of the starting price before coupon and tax.
Coupon impact
A fixed coupon can further reduce the subtotal after percentage discount. This helps model promo codes, store credits, or cart-level coupons.
Tax and checkout
Tax can make the final total higher than the advertised sale price. This calculator applies tax after discounts, which is common but not universal.
