Summary
Enter an original price, add up to 6 coupons in any order, and see a step-by-step breakdown of your total savings after stacking discounts, cashback, and tax.
How it works
- Enter the original price of the item.
- Add coupon rows — choose percent off, dollar off, or cashback for each.
- Optionally enter a sales tax rate to see the final after-tax price.
- The calculator applies coupons in the standard retail order: percent discounts first, then dollar-off coupons, then cashback after tax.
- A step-by-step breakdown table shows the running price after each coupon so you can see exactly what each deal contributes.
Use cases
- Plan a shopping trip using a store sale, a manufacturer coupon, and a cashback app like Rakuten or Ibotta.
- Verify the final price before checkout when stacking an Amazon coupon with a promo code.
- Compare two different coupon combinations to find which stacking order saves more.
- Calculate the effective discount percentage when combining multiple small discounts.
