Amount paid now
760TWD
Amount paid now is what you pay for this purchase. Later rewards have not yet been received and are not cash discounts.

Cost after rewards725 TWD
Apply the discount, then the coupon. Rewards are based on the merchandise amount after the coupon; shipping earns none. Rewards do not reduce what you pay now. Thresholds and rounding follow the merchant's rules.
Method and scope
Multiply the price by each discount number divided by 10, then subtract the coupon, with the item subtotal floored at zero. Add shipping afterwards; calculate cashback on the item subtotal, applying the optional cap.
Cashback is shown separately because it is not cash already received. Two 20% discounts give a 0.8 times 0.8 multiplier, not a 40% discount.
The store may apply coupons, rounding or reward eligibility differently. The tool does not infer spending thresholds, point value or terms of an offer.

How the calculation works
Multiply the price by each discount number divided by 10, then subtract the coupon, with the item subtotal floored at zero. Add shipping afterwards; calculate cashback on the item subtotal, applying the optional cap.
Worked example
For an original price of TWD 1,000, enter 8 to pay 80% of the price. An additional TWD 100 coupon and TWD 60 shipping give TWD 760 paid now; 5% cashback on TWD 700 is TWD 35.
Understanding the answer
Cashback is shown separately because it is not cash already received. Two 20% discounts give a 0.8 times 0.8 multiplier, not a 40% discount.
