Recent changes to this card's data

2026-09-13 — Citi Custom Cash

Verified accurate — no changes. Still closed to new applications (existing cardmembers unaffected); fee, network, top-category cash back mechanic, and coverage re-confirmed against citi.com and independent reviewers.

2026-08-23 — PayPal Cashback Mastercard (new card)

$0 annual fee, 3% cash back through PayPal checkout / sending money to other PayPal users, 1.5% cash back everywhere else Mastercard is accepted, no rotating categories (paypal.com/us/digital-wallet/manage-money/paypal-cashback-mastercard; paypal.com/us/webapps/mpp/cashback-faq). 3% foreign transaction fee, $0 annual fee confirmed directly in Synchrony's Rates and Fees Table (synchronybankterms.com); no no-FTF benefit listed.
The 3% rate's exact scope was confirmed against Synchrony's Rewards Program Terms and Conditions rather than marketing copy: it applies to purchases made through the linked PayPal account online and to sending money to other PayPal users through PayPal — a payment-channel distinction, not a merchant category, so it's shown but never auto-counted against any spend category. No source (official Rewards Terms, PayPal's own FAQ, or NerdWallet/Bankrate secondaries) confirms Venmo checkout earning the 3% rate — despite the shared PayPal Inc. ownership, the terms name only "your PayPal account," so Venmo is not modeled as qualifying. Authorized users earn only the 1.5% base rate today (their cards can't be linked to a PayPal account), per the same Rewards Terms.
Flat cash back (1 cent/point, paid to a linked PayPal account, no redemption-value variance) — the two-tier 3%/1.5% *earn* structure doesn't change that, matching the citi-custom-cash.json precedent for a variable-earn/flat-redemption cash-back card.
Benefits left empty. Bankrate's dedicated review states the card "lacks annual credits, travel insurance and rideshare or delivery service benefits"; one other review claims extended warranty and price protection, but that reads as generic Mastercard boilerplate possibly borrowed from a sibling card. With sources disagreeing, no coverage was added on spec — and a same-day follow-up against Synchrony's own cardholder agreement confirmed the empty list is genuinely correct (see the entry above).
Omitted as issuer/network-generic non-monetizable extras: Mastercard ID Theft Protection, standard Zero Liability, microchip technology, digital-wallet support, and PayPal's variable opt-in offer-stacking. The sibling PayPal Extras Mastercard was not requested and not added.

2026-08-21 — Citi Custom Cash (new card)

Added new card citi-custom-cash. $0 annual fee, Mastercard, earning Citi ThankYou Points. Closed to new applications since 2026-05-28 (existing cardmembers unaffected, and the product may return) — badged accordingly. Source: https://web.archive.org/web/20260401031104/https://www.citi.com/credit-cards/citi-custom-cash-credit-card
Point values mirror Citi Double Cash's: cash floor at 1.0 cents/point (default), pooled-with-Strata-Premier-or-Elite at 1.7 cents/point. Noted that the card can now also transfer solo to most ThankYou partners except American Airlines at a reduced ~0.7 ratio, per a 2025 Citi policy expansion.

Earning: 1% unlimited on everything else, plus the headline 5%-on-your-top-eligible-category-per-billing-cycle mechanic (restaurants, gas, groceries, select travel/transit/streaming, drugstores, home improvement, fitness clubs, live entertainment; $500/cycle cap, then 1%). At first the 5% could only be displayed, not valued — the calculator gained a real top-category mechanic days later and this card now uses it (see the "smarter valuation mechanics" entry above).

Did NOT add the "plus 4% additional cash back on hotels, car rentals, and attractions booked with Citi Travel" promotion — confirmed expired 2026-06-30, before this research date. Source: https://www.nerdwallet.com/credit-cards/learn/benefits-of-the-citi-custom-cash-card
Added Extended Warranty (doubles original warranty, max 24-month extension, added Nov 2024) — same benefit/wording already on citi-double-cash.json. Not visible in the archived primary page's own benefits tabs; confirmed via 4 mutually consistent secondaries. Sources: https://frequentmiler.com/citi-adds-24-month-extended-warranty-to-double-cash-and-custom-cash/ , https://www.doctorofcredit.com/citi-adds-24-month-extended-warranty-benefit-on-various-cards/ , https://milestalk.com/citi-double-cash-card-regains-extended-warranty/
No purchase protection, travel insurance, or rental CDW (Citi removed these card-wide in 2019 and never restored them here); no no-FTF benefit (3% foreign transaction fee applies). Generic issuer/network extras (Mastercard ID theft monitoring, $0 liability, free FICO score, fraud alerts, Citi Quick Lock, Citi Entertainment) intentionally omitted per skill convention.
