Citi Custom Cash

Heads up: Citi stopped accepting new applications for the Custom Cash on May 28, 2026. If you already have one, nothing changes — Citi says existing cardmembers keep the card and its benefits. If you don't, you can't open one anymore; Citi now steers new applicants to the Double Cash. Everything below is for current cardholders.

The Citi Custom Cash is a clever little card with one party trick, and it does that trick really well. It automatically earns 5% cash back on your highest eligible spending category each billing cycle — up to $500 in spending. No activation, no choosing, no quarterly opt-in nonsense. Citi figures out where you spent the most and gives you 5% on it. After $500, you're back to 1%.

Think of it as a surgical tool, not a Swiss Army knife. Eligible 5% categories include restaurants, gas stations, grocery stores, select travel, select transit, select streaming, drugstores, home improvement stores, fitness clubs, and live entertainment. That's a wide net. The play is simple: use this card for one specific spending category each month — groceries, dining, gas, whatever — and let it auto-detect your top category. Pair it with a flat-rate card for everything else and you've got a smart two-card setup.

• Automatic 5% Cash Back: Earns 5% in your top eligible spending category each billing cycle — no activation, no choosing, no hassle. It just... works. Refreshingly hands-off.
• Wide Category List: Ten eligible 5% categories covering dining, gas, groceries, streaming, transit, travel, drugstores, home improvement, fitness, and entertainment. Odds are, your biggest monthly expense is on this list.
• No Annual Fee: $0 per year. Free card, 5% back. Hard to complain.
• Citi ThankYou Points Compatible: Rewards are earned as ThankYou Points. Here's the power move: if you hold a Citi Strata Premier or Strata Elite, your Custom Cash points transfer to airline and hotel partners at the full premium-card ratios — 1:1 to most airlines. (Solo, the card can transfer too, but at reduced ratios — 1:0.7 to most airlines.) That turns 5x grocery points into airline miles. Massive.
• 24-Month Extended Warranty: Citi added this in late 2024 — it doubles the original manufacturer's or store warranty, up to a max of 24 months. Quiet, but handy for electronics. (The 0% intro APR was a new-account offer, so it ended when Citi stopped taking applications.)
• Citi Entertainment Access: Presale tickets and preferred seating for concerts, sports, and events. A nice cherry on top.

One thing to watch: the 3% foreign transaction fee means this card stays home when you travel abroad. Use a no-FTF card internationally and keep the Custom Cash for domestic spending where it shines.

None — the card is closed to new applicants. Citi stopped taking Custom Cash applications on May 28, 2026, and the old welcome offer ($200 cash back, paid as 20,000 ThankYou Points, after $1,500 in spend in the first 6 months) went with it. If you want a Citi cash back card with a bonus today, Citi points you to the Double Cash.

• 5% cash back (5x ThankYou Points) on your top eligible spending category each billing cycle, on up to $500 in purchases
• 5% cash back total (5x ThankYou Points) on hotels, car rentals, and attractions booked through Citi Travel — an extra 4% on top of the base 1%
• 1% cash back (1x ThankYou Points) on all other purchases

Eligible 5% categories: restaurants, gas stations, grocery stores, select travel, select transit, select streaming services, drugstores, home improvement stores, fitness clubs, and live entertainment.

The $500 per-cycle cap means the top-category 5% maxes out at $25 per month — $300 per year in bonus value. Not going to change your life, but for a free card that requires zero effort, that's solid. For spending beyond $500 in your top category, you'll want a complementary card picking up the slack. The automatic category detection is based on merchant category codes (MCCs), so there's no gaming it — Citi picks your top category based on actual spending.

• Statement Credit: Redeem ThankYou Points at 1 cent each against your balance. Simple and clean.
• Direct Deposit: Cash out points directly to your bank account. Same 1 cent per point, different destination.
• Gift Cards: Redeem for retail gift cards at 1 cent per point. No bonus, no reason to choose this over cash.
• Transfer to Partners: If you also hold a Citi Strata Premier or Strata Elite, your Custom Cash ThankYou Points pool together and transfer to airline/hotel partners at the full premium-card ratios (1:1 to most airlines). On its own, the Custom Cash can transfer too, but at reduced ratios (1:0.7 to most airlines). This is the real unlock — your 5x grocery points become airline miles worth 1.5-2+ cents each.
• Shop with Points: Use points at checkout with select retailers (usually poor value). Skip this one.

The real power play is pairing the Custom Cash with a Strata Premier or Strata Elite. On its own, you're getting a solid 5% cash back card. Combined with a Strata card, your 5x points become full-value (1:1) transferable currency — turning your grocery spending into first-class flights. That's a no-fee card punching way above its weight class.

• Citi Entertainment: Access to presale tickets and special experiences for concerts, dining, and sporting events. Not a travel perk per se, but a nice lifestyle bonus.
• Extended Warranty: Doubles the original manufacturer's or store warranty, up to a max of 24 months. Quietly useful for electronics and appliances.
• Citi Merchant Offers: Targeted statement-credit deals on shopping, dining, and travel — enroll in the offer, make the qualifying purchase, get the credit.

Let's be clear: this is not a travel card. No lounges, no Global Entry, no trip insurance, and no car rental coverage either. The Custom Cash's value is purely in its earning rates and its synergy with the Citi ThankYou ecosystem. And that's fine — not every card needs to be a travel card.

The Custom Cash wins for hands-off 5% earning in a single category — no activation, no calendar reminders. The Freedom Flex has the same effective cap ($1,500/quarter vs. $500/cycle — about $500 a month either way), plugs into Chase's ecosystem, and now has no foreign transaction fee, but you have to activate rotating categories every quarter. The SavorOne trades peak rates for broader uncapped 3% categories and no FTF, but it now carries a $39 annual fee. The smart play? If you already hold the Custom Cash, keep it and pair it with one of these — they complement each other nicely.

• Single-category heavy spenders who consistently spend the most in one area each month — the automatic detection rewards predictable habits
• Citi ThankYou ecosystem members who hold a Strata Premier or Strata Elite and already have a Custom Cash — a free 5x feeder for their points pool
• Set-it-and-forget-it types who refuse to activate rotating categories on principle (we see you)
• Current cardholders wondering whether to keep it — yes: no annual fee, and Citi says existing accounts aren't affected by the closure
• Multi-card strategists who want a targeted 5% card to complement a flat-rate base card — the perfect specialist in a broader lineup
