What this calculator does
This Cyber Monday calculator helps you see your true final price when a percentage-off sale is stacked with an additional flat coupon amount, plus shipping.
How it’s calculated
The sale discount is applied first to the original price, then the flat coupon amount is subtracted from that discounted price (never going below zero). Shipping, if any, is added last to give your final checkout total. Total savings and percent saved compare your final item price against the original price.
- The calculator applies the percentage discount before the flat coupon, which matches how most retailers stack sale and coupon discounts at checkout.
- Enter 0 for shipping if your order qualifies for free shipping.
This tool is for general shopping and budgeting purposes only.
