🏷 Coupon & Cashback Calculator
Stack a sale, coupon, cashback, and loyalty points to find your true final price and total savings.
How Deal Stacking Works
Stacking discounts means applying multiple savings mechanisms to the same purchase. The order matters — each discount typically applies to the running price, not the original.
This calculator applies discounts in the most common merchant order: sale price first (reduces the original price), then the coupon is applied to the post-sale price, and finally cashback is calculated on the amount you actually pay at checkout.
Loyalty points are treated as earned rewards on the final checkout price, then converted to a dollar value using your points-to-dollar rate.
Sale + Coupon
Most retailers apply coupon codes to the sale/current price, not the original MSRP. Always check the terms.
Cashback portals
Cashback is usually calculated on the final price paid (after all discounts), not the pre-discount price.
Credit card cashback
Credit card rewards apply to your charged amount. Stack these on top of portal cashback for maximum savings.
When stacking beats a single deal
Even a small cashback rate adds up significantly over time. A 5% discount + 5% cashback yields ~9.75% total — better than either alone.
