Triple Stack Rewards Calculator

Shopping portals (like Rakuten, TopCashback, Swagbucks, or BeFrugal) pay you a percentage of your purchase when you click through their site to a merchant. Retailers pay them a commission for referrals, and they share part of it with you. Portal rates range from 1-15% depending on the merchant and current promotions. You still earn all your credit card rewards on top of the portal cashback.

Card-linked offers are discounts automatically added to your credit card account. Programs like Amex Offers, Chase Offers, and Bank of America BankAmeriDeals let you activate deals in your card account. When you use that card at the qualifying merchant, you get a statement credit (typically 5-20% back or a fixed dollar amount). These stack with card rewards and portal cashback because they're separate programs.

Yes, absolutely. Credit card rewards, shopping portals, and card-linked offers operate independently and can all be earned on the same transaction. However, you must use the right card (one with a card-linked offer activated), shop through the portal link, and meet the offer terms. For online purchases, this is straightforward: click the portal link, activate the offer, and pay with the right card. In-store purchases can only stack the card + offer.

Amex cards (Gold, Blue Cash Preferred, Platinum) are excellent because Amex Offers are plentiful and often generous. Chase Sapphire Preferred and Reserve work well with Chase Offers. For high bonus categories, use Citi Custom Cash (5% rotating top category) or category specialists like Amex Blue Cash Preferred (6% groceries/streaming). The best card depends on the merchant's category and which offers you have available.

Rakuten is the largest and most popular shopping portal in the US. Rates vary by merchant: 1-2% for big retailers like Amazon and Walmart, 4-8% for clothing/beauty (Nike, Sephora), and up to 12-15% during promotional events. Rakuten pays out quarterly via PayPal or check. Over a year, heavy online shoppers can earn $300-1,000+ through Rakuten alone before adding credit card rewards and card-linked offers.

Yes, frequently. Portal rates change based on retailer contracts, seasonal promotions, and portal competition. A merchant might be 2% one day and 8% the next (often around major sales events like Black Friday). Use browser extensions like Honey, Capital One Shopping, or Rakuten's own extension to automatically compare portal rates before checkout. Always check rates before clicking through to ensure you're getting the best deal.

For large purchases ($200+), absolutely yes. The difference between earning 1.5% (basic card, no portal, no offer) and 12% (triple stack) on a $500 purchase is $52.50 in your pocket. For everyday small purchases, it's less critical, but if you're shopping online anyway, clicking through a portal takes 5 seconds and adds 2-8% to your return. Over a year, optimizing your top 10-20 purchases can yield an extra $200-500 in rewards.
