Why the answer isn’t “whichever pays more”
Every portal comparison you’ve read ranks by headline rate. That’s the wrong metric for anyone buying above a few hundred dollars, because the three portals hand you three different kinds of money. Rakuten can pay you in transferable points. TopCashback pays cash. Capital One Shopping pays gift cards. A 4% rate in points that you’ll redeem at 1.7 cents each is worth more than a 5% rate in cash, and a 5% rate in cash is worth more than a 6% rate in Best Buy credit you didn’t want.
So the comparison below runs in this order: what you get paid in, how soon you get it, what they pay you to join, then the rates, then reliability, then the extension problem. The recommendation by shopper type is at the end.
Payout form: points, cash, or gift cards
Rakuten defaults to a check or PayPal, but you can switch the payout to American Express Membership Rewards (1 cent of cashback becomes 1 point) or to Bilt points. That switch is the reason Rakuten is the first layer on nearly every Stackable page. Ten dollars of cashback is $10 in cash or 1,000 MR points, and 1,000 MR points redeemed for a premium-cabin transfer partner flight are routinely worth $15 to $20. No other portal offers a conversion like this. One caveat from this year: the Bilt conversion changed on May 15, 2026, and some members report a lower rate since, so check your payout settings before assuming 1 point per cent.
TopCashback pays cash. PayPal, Venmo (added March 2026), or ACH bank transfer, with no minimum on any of those three. It also offers Visa and Amex virtual cards and a long gift-card list, and it has a history of paying a bonus of a few percent when you take a gift card instead of PayPal (6% on Visa gift cards during a 2019 promotion, for example). Those bonuses come and go; when we checked, none was advertised on the help pages. Cash is cash. It cannot become points, but it also can’t lose value.
Capital One Shopping pays “Shopping Rewards” credits that redeem for e-gift cards from roughly 50 brands. No cash, no PayPal, no bank, no points. Marriott and Hotels.com are on the list, which helps readers of this site, but a dollar of credit is worth at most a dollar and often less, because you’ll spend it at a store you wouldn’t have otherwise chosen. There’s no minimum, which is the one thing the payout has going for it.
| Rakuten | TopCashback | Capital One Shopping | |
|---|---|---|---|
| Payout form | Check, PayPal, Amex MR points, Bilt points | PayPal, Venmo, ACH, Visa/Amex virtual card, gift cards | E-gift cards only |
| Minimum | $5.01 confirmed | None for PayPal, Venmo, or ACH | None |
| Schedule | Quarterly: Feb 15, May 15, Aug 15, Nov 15 | On demand, once each purchase is “payable” | Credits post 30 to 90 days after purchase |
| Points conversion | Yes (MR, Bilt) | No | No |
| Welcome bonus | $50 after $50+ purchase in 90 days (through Sept 30, 2026) | $15 (verified Sept 14) | $80 in gift-card credit after 90 days with the extension active |
| Referral (to the referrer) | $50 | $10 per the help page | $80, capped at $1,900 total |
| Claim window | Not stated on the help page; file within 30 days | 100 days at most stores | Support form, no stated window |
| Browser extension | Yes | Yes | Yes, and it’s the best coupon tester of the three |
Minimums and schedule
Rakuten’s quarterly “Big Fat Payment” is the slowest schedule of the three by design. Cashback earned July 1 to September 30 pays November 15; earned October 1 to December 31 pays February 15. Anything under $5.01 rolls to the next quarter. If you buy on July 2, you wait about four and a half months. The trade for that wait is the points conversion, and for most people reading this page that trade is worth taking.
TopCashback has no schedule. Each purchase moves from pending to confirmed to payable as the retailer’s return window closes and the network remits the commission, and once it’s payable you cash out whenever you want, in any amount. In practice “payable” takes several weeks to a few months depending on the retailer. The practical difference is that a $30 win at Saks can be in your PayPal in six weeks instead of sitting in a quarterly bucket.
Capital One Shopping is the slowest to show anything at all. Purchases can take days to appear as pending, and credits post 30 to 90 days after purchase. Referral bonuses have a documented history of posting late.
Welcome bonuses and referrals
Rakuten’s $50 new-member bonus after a $50+ first purchase within 90 days is the strongest cash offer of the three, and it’s paid in whatever form your account is set to, so switch to Amex or Bilt before your first purchase and it arrives as 5,000 points. Doctor of Credit has tracked this offer since September 2025; it has been extended several times and is currently listed through September 30, 2026. The referrer gets the same $50.
How Rakuten works, and how to get the $50 welcome bonus →
Capital One Shopping’s $80 is bigger on paper. Read the conditions: install the extension within 7 days of creating the account, keep it installed with full permissions and use it “regularly” for 90 days, and the bonus arrives as gift-card credit up to 30 days after that. It’s real money if you’d run the extension anyway, and it’s also the mechanism by which Capital One’s extension ends up overwriting your Rakuten clicks for three months. Full terms and the rate table are on the Capital One Shopping page.
TopCashback’s bonuses are the most variable. Doctor of Credit has covered $25 to $40 promotional sign-up offers over the years, each requiring $10 of payable cashback before the bonus unlocks. The standing offer when we checked was $15 for new members, and the help page advertises “Refer & Earn $10” for the referrer.
Rates at premium retailers, verified on our own pages
Every number below was read from the portal’s store page for the retailer’s own domain on September 14 or 15, 2026, and lives on the linked retailer page with its exclusions. Rates change weekly; the retailer pages carry the current number.
| Retailer | Rakuten | TopCashback | Capital One Shopping | Leader today |
|---|---|---|---|---|
| Bergdorf Goodman | 15% (base 2%) | 2% | up to 2% | Rakuten |
| Sixt | 12% (Pay Now) | 8% | 3% | Rakuten |
| StubHub | 10% | 10% | 2% | Tie; Rakuten for points |
| Vrbo | 6% (10% Hawaii) | 6% | 1% | Tie; Rakuten for points |
| Marriott | 3%, $100 cap | 4%, $200 cap | up to 0.5% | TopCashback |
| Hertz | 2.5% | 5% | 2% | TopCashback |
| Saks Fifth Avenue | 2% | 5% | 1% | TopCashback |
| Neiman Marcus | 2% | 5% (not on sale items) | up to 2% | TopCashback |
| Bloomingdale’s | 2% | 4% | 1% | TopCashback |
| Mr Porter | 2% | 7% new ($350+), 4% existing | up to 2.5% | TopCashback |
| Sephora | 2% | 2.5% | 1% | TopCashback |
| Nordstrom | No cash back | 2.4% | Not listed | TopCashback |
| Net-a-Porter | up to 2.5% | 3% (1% sale) | 8% | Capital One Shopping |
| Bluemercury | 2% | 3% | 8.5% | Capital One Shopping |
| Farfetch | 2% | 4.5% new over $800, 1% existing | 7% | Capital One Shopping |
| Dyson | 1% base, 10-12% windows | 2% | 6% | Capital One at base; Rakuten in a window |
| lululemon | No cash back (spikes to 15%) | Unverified | 2% | Capital One Shopping |
| Away | 2% | Not listed (404) | 2% | Tie |
| Bose | 2% | Not listed (404) | 2% | Tie |
| Apple | 0% on hardware | 0% on hardware | 0.5% | Nobody, really |
The pattern is consistent enough to plan around. Rakuten wins on its spike stores (Bergdorf, Sixt, Dyson in a window, lululemon in a window) and ties at the 2% floor. TopCashback wins the department stores and the Yoox-Net-a-Porter fashion sites, plus hotels and car rental, usually by 2 to 5 points. Capital One Shopping is last almost everywhere and then, at a handful of luxury fashion and beauty sites, leads by 5 or 6 points for no reason anyone can explain. The gap in coverage matters too: TopCashback simply has no store page for Away, Bose, Design Within Reach, Monos, or Rimowa.
Convert before you compare. TopCashback’s 5% at Saks in cash is $25 on $500. Rakuten’s 2% is $10 in cash, or 1,000 MR points, which at 1.7 cents is $17. TopCashback still wins there. At Marriott, TopCashback’s 4% cash against Rakuten’s 3% in points is closer than it looks: on $1,000, $40 cash versus 3,000 points worth roughly $51 at 1.7 cents. The points payout flips the leader.
Tracking reliability and the claims process
All three fail sometimes. Ad blockers strip tracking parameters, a second extension overwrites the cookie, a promo code the portal didn’t list voids the commission. What differs is how each handles it.
TopCashback publishes the clearest process. Most store pages accept a missing-cashback claim within 100 days of purchase, and the site’s own FAQ says the network can take up to three months to respond once a claim is lodged. Several of its store pages require an empty cart before you click through, and at least one retailer on this site (Sixt) is flagged as not accepting missing-cashback claims at all. Read the store page’s terms before you buy, not after.
Rakuten’s “Find My Cash Back” tool resolves a large share of claims immediately, and its shopping-trip log shows within hours whether the click registered, which is the single most useful reliability feature of any of the three. What we could not find on Rakuten’s help pages is a stated deadline for inquiries. Third-party guides say 30 to 45 days. Treat 30 as the limit.
Capital One Shopping is the weakest here. Purchases can take days to show as pending, credits take 30 to 90 days, and users have reported referral bonuses that needed a support ticket to appear. Support has resolved those on request, but “resolved on request” is not the same as reliable.
Browser extensions and the last-click problem
All three sell their extension as the convenient path, and for a single portal it is: land on a store, click activate, the tracking fires without visiting the portal first. The problem starts the moment you have two of them installed.
Affiliate networks attribute a sale to the last click. If you click through Rakuten’s site, then Capital One Shopping’s extension detects the store and asks to activate, and you accept, Capital One’s cookie is now the last one. Rakuten’s shopping trip still shows in your log, and nothing pays. The reverse is equally true, and TopCashback’s extension behaves the same way. Capital One’s extension is the aggressive one: its coupon-testing pop-up appears at checkout on thousands of stores, which is exactly where a stray click does the most damage, and its $80 referral requires you to leave it running with full permissions for 90 days.
The clean setup is one browser profile per extension, or one extension enabled and the others disabled, with the portal site (not the extension) used for the click on any order over a couple hundred dollars. The stacking guide has the full checkout order.
Recommendation by shopper type
You hold an Amex Membership Rewards card or a Bilt account. Rakuten, set to points, is your default, and you compare against TopCashback only when TopCashback’s cash rate exceeds Rakuten’s rate by more than about 70% (the points premium at 1.7 cents). At Saks today that test passes (5% vs 2%). At Marriott it doesn’t (4% vs 3%).
You want cash and want it soon. TopCashback. No minimum, on-demand payout, and it leads at the department stores and hotels most people on this site buy from. Keep a Rakuten account anyway for Bergdorf, Sixt, and the spike windows.
You buy luxury fashion and beauty online. Check all three, because this is the one category where Capital One Shopping’s odd spikes (Net-a-Porter, Farfetch, Bluemercury) beat both others by 5 points or more. Take the gift card when the math clearly wins and not otherwise.
You mostly buy from Apple, Away, Bose, Sonos, or Samsung. The portal layer is 0% to 2% everywhere and the leader doesn’t matter. Collect Rakuten’s $50 welcome bonus on one qualifying purchase, then spend your attention on card offers and timing instead; see /offers for what’s live.
You’re new to all of this. Open Rakuten, switch the payout to points before your first purchase, and use it for 90 days to earn the $50. Add TopCashback the first time it shows a higher rate on something you were going to buy anyway. Install Capital One Shopping in a separate profile when you’re confident you won’t let it activate over the others.
Compare all three, then start with Rakuten
Rakuten is the one of the three that pays in Amex or Bilt points and the one with a $50 welcome bonus. Join through our link, make a $50+ purchase within 90 days, and the bonus posts with your next quarterly payment.
