Coupon stacking calculator
See how the order of discounts changes your total, or find the best single offer when codes cannot combine.
Your estimated total
Stacked offers bring the total to $70.00.
Estimated savings from the undiscounted total: $38.00.
Worked example
On a $100 cart with $8 shipping, applying 20% off first leaves $80; a further $10 off leaves $70. If free shipping also combines, the checkout total is $70. Without stacking, the best single offer is 20% off, for an $88 total.
Assumptions
The percentage applies to the remaining subtotal at its step, with each step rounded to the nearest cent. The fixed discount cannot take the subtotal below $0. Free shipping removes the entered shipping charge. Stores decide whether codes can combine, which items qualify and the order in which discounts apply; check the offer terms and the actual checkout.
