The UOB One Card is a cashback card that rewards steady, predictable spending rather than one big splurge. Its real draw is up to 3.33% flat cashback on almost everything, plus 5% to 6.67% on Grab, Shopee, SimplyGo, McDonald's and groceries, but only if you spend the same minimum amount in every one of the three statement months in a quarter, with at least 10 transactions each month. Miss any month and the whole quarter's bonus is gone. The 'up to 10%' or 'up to 20%' you see in ads is a new-customer promo stacked on top for the first quarter, not the ongoing rate. So the honest answer to whether it is worth it: yes, if you can charge at least S$2,000 a month consistently and your spending leans toward those bonus merchants; no, if your spend is lumpy or under S$600 a month, in which case a flat-rate card or a savings account does better.
The UOB One Card runs on a quarterly tiered system, not a monthly one. A 'quarter' is three consecutive statement months counted from your card opening date. To earn the quarterly cashback, you have to hit the same minimum spend in each of those three months, and charge at least 10 separate transactions to the card each month. Hit the bar in all three months and UOB credits the cashback after the quarter ends; fall short in even one month and you get nothing for the whole quarter (the only exception is a pro-rated payout in your very first quarter).
The figures below are the standard ongoing terms that apply to every cardholder, taken from the UOB One Card terms updated 22 September 2025. There are three tiers, and the effective rate works out to roughly 3.33% at every tier because both the spend and the payout scale together.
| Tier | Min spend per statement month | Quarterly cashback | Effective rate |
|---|---|---|---|
| Tier 1 | At least S$600 (under S$1,000), 10+ transactions | S$60 | About 3.33% |
| Tier 2 | At least S$1,000 (under S$2,000), 10+ transactions | S$100 | About 3.33% |
| Tier 3 | At least S$2,000, 10+ transactions | S$200 | About 3.33% |
The effective rate is the same at each tier, but the spend you commit is very different. At Tier 1 you charge S$600 a month for three months, which is S$1,800 of spend for S$60 back. At Tier 2 it is S$3,000 of spend for S$100. At Tier 3 it is S$6,000 of spend for S$200. Divide them out and you land near 3.33% each time (S$60 on S$1,800 is 3.33%, S$100 on S$3,000 is 3.33%, S$200 on S$6,000 is 3.33%).
Here is the part people miss. If you spend right at the bottom of a tier you do best, and if you overspend within a tier you dilute your return. Charge S$999 a month and you are still on Tier 1: S$2,997 of spend earns just S$60, which is 2.0%. Charge S$1,000 instead and you jump to Tier 2 and earn S$100. So the card rewards spending exactly at a tier threshold, not above it.
There is also a tiny base cashback of 0.03% on all transactions, paid the following February if you earned no quarterly cashback in a calendar year. It exists so the card pays something even if you never hit a tier, but at 0.03% it is a rounding error, not a reason to hold the card.
Run your own number first. Pull three months of statements, add up what you reliably charge per month, and check which tier you would sit in. If you can't comfortably clear S$600 every single month, this card is not built for you. A quick split using the personal budget calculator tells you whether your real monthly card spend clears a tier.
Ads talk about rates; what matters is the dollar ceiling. On the standard ongoing terms the One Card has a clear maximum, and it is lower than the headline percentages suggest. At Tier 3 the flat quarterly cashback is S$200. The bonus on Grab, Shopee, SimplyGo, McDonald's, groceries and SP utilities is capped at S$120 per statement month, so across three months a quarter that bonus tops out at S$360. Add the two and the most you can collect in a single quarter is S$560, which is S$2,240 across a full year if you max out every quarter.
Hitting that ceiling is harder than it reads. To bank the full S$360 of bonus you would need to put well over S$5,000 a quarter through the bonus merchants alone, on top of the S$2,000 a month of general spend that keeps you on Tier 3. Most households charge a few hundred dollars a month to those merchants, not over a thousand, so the realistic bonus is a fraction of the cap. Treat S$560 as the theoretical roof, not the expected return.
The first quarter can sit above this for new customers because the Enhanced Cashback promo stacks on top, but it is bound by the same S$120 monthly bonus cap, so even the promo cannot push a single statement month past S$120 of bonus plus the flat tier payout. Once the promo ends you are back to the S$560 quarterly ceiling described here.
| Component | Cap | Condition |
|---|---|---|
| Flat quarterly cashback | S$200 | S$2,000+ each month, 10+ transactions every month |
| Bonus on selected merchants | S$120 per statement month (S$360 a quarter) | Only after the flat cashback is earned |
| Most you can earn in a quarter | S$560 | Both caps maxed in the same quarter |
| Most you can earn in a year | S$2,240 | All four quarters maxed |
On top of the flat quarterly cashback, the card pays extra on a fixed list of merchants UOB calls Selected Merchant Transactions. You only earn this 'Additional Cashback' if you already met the minimum spend and earned the quarterly cashback for that quarter, so it is a top-up, not a standalone benefit.
The standard ongoing rates on the main merchants are 5% if you are on Tier 1 or Tier 2, and 6.67% if you are on Tier 3. Groceries (stores coded MCC 5411) pay nothing on Tier 1, 2.67% on Tier 2 and 4.67% on Tier 3. Singapore Power utilities pay a flat 1%, and Shell pays 1.67% but only on Tier 3. Separate from the card cashback, UOB cardholders get pump discounts at Shell and SPC that stack on top, so the real saving on petrol is higher than the 1.67% bonus alone, but those discounts come from the fuel partnership rather than the cashback engine. Whether a merchant counts at all comes down to its merchant category code, so a shop that looks like a supermarket but is coded as something else will not pay the grocery rate.
UOB markets the card with figures like 'up to 10% cashback' and, in sign-up campaigns, 'up to 20% cashback for your first quarter'. Both are real, but neither is the everyday rate, and it pays to know which is which before you apply.
The 'up to 10%' comes from being on Tier 3 (6.67% on the merchants) and a separate new-to-UOB Enhanced Cashback promo that adds another layer on the same merchants. During the promotion running 15 May 2026 to 30 September 2026, new-to-UOB applicants get an extra 5% on Tier 1 and 2 and an extra 10% on Tier 3 on those merchants, for the first quarter only. Stack the 6.67% ongoing rate with the 10% promo and Tier 3 grocery and merchant spend can briefly reach the headline figures.
Two things keep this grounded. The promo only applies to your first quarter from card approval, then you drop to the standard 5% to 6.67%. And the Enhanced Cashback is separately capped at S$120 per statement month, the same as the standard Additional Cashback, so there is a hard ceiling on how much of that high rate you can actually collect.
If you are weighing this against other cards, our roundup of the best credit cards in Singapore puts the One Card next to its closest rivals on rate, cap and minimum spend.
The annual fee is S$196.20, waived for the first year. The first supplementary card is free; the second onwards is S$98.10 each. Like most local issuers, UOB will often waive the fee on request once you have spent regularly through the year, so it is worth a call before you pay it. The mechanics are the same as any other card, covered in our guide to waiving a credit card annual fee.
Overseas and foreign-currency spend carries a 3.25% fee, which is standard for Singapore bank cards but means the One Card is a poor choice for travel or overseas online shopping. The cashback you earn abroad will usually be smaller than the fee you pay.
Income requirements follow the usual thresholds: S$30,000 a year for Singaporeans and permanent residents aged 55 and under, S$15,000 a year for those aged 56 and above, and S$40,000 a year for foreigners. You must be at least 21 to hold a principal card. If you cannot meet the income bar, UOB also issues the One Card on a secured basis against a fixed deposit of at least S$10,000, which is a route older applicants and those between jobs sometimes use. Your credit limit and total borrowing are capped by MAS rules that apply across all banks, so check those before assuming you can spend to Tier 3. Approval also depends on your record with the credit bureau; if you are unsure where you stand, read our guide to credit scores in Singapore before you apply.
Two fees catch people who slip up, and both dwarf the cashback. Miss the minimum payment by the due date and UOB charges a S$100 late fee plus an extra 3% a year of interest on top of the usual rate. Draw cash on the card and the cash advance fee is 8% of the amount or S$15, whichever is higher, with interest running from day one. Neither earns cashback, and a single late fee erases more than a full quarter at Tier 1.
The exclusion list is long and catches a lot of everyday spend, so check it against your own bills before you assume a category counts. None of the following earns base, quarterly or additional cashback, and worse, several of them do not count toward your minimum spend either, which can quietly push you off a tier.
Insurance premiums, education and school fees, tax payments to IRAS, most government and hospital payments, EZ-Link and transit top-ups, AXS and most bill-payment platforms, PayPal, brokerage and securities transactions, and any cash advance or balance transfer are all excluded. Wallet top-ups to Grab and Shopee are excluded even though spending at those merchants is rewarded, so top up your wallet and you get nothing, but pay the merchant directly and you do.
People often confuse the two. The UOB One Card is a credit card that pays cashback. The UOB One Account is a savings account that pays bonus interest partly on the condition that you spend at least S$500 a month on an eligible UOB card and credit your salary. They are designed to be paired: use the One Card to hit the account's spend requirement, and you earn cashback on the card and bonus interest on the account from the same spending.
That pairing is where the One Card earns its keep for many people. The One Account currently pays up to 1.90% a year on balances up to S$150,000 when you both credit a salary of at least S$1,600 and charge at least S$500 a month to an eligible UOB card. If you are already chasing that interest, the card spend you do for it is effectively free cashback on top. If you only want the card, judge it on the cashback alone, and the tier maths above is what matters.
If your goal is the interest rather than the cashback, compare what the account pays against simpler alternatives first. For a low-effort cash return, the best savings accounts in Singapore and instruments like Singapore T-bills often beat the headline rate once you account for the hoops a bonus-interest account makes you jump through.
The honest comparison for most people is not One Card against another tiered card; it is One Card against a no-strings flat-rate card. UOB sells both. The Absolute Cashback Card pays a flat 1.7% on almost everything with no minimum spend, no tiers and no S$120 monthly cap. The One Card pays roughly twice that headline rate, but only if you hit a tier in all three months of a quarter and your spend skews toward the bonus merchants.
Read the table as a break-even test. The One Card wins on rate when your spending is steady, predictable and partly on Grab, Shopee, SimplyGo, McDonald's or supermarkets. The flat-rate card wins on certainty when your spend is lumpy, low, or spread across categories the One Card ignores, because 1.7% on everything beats 3.33% on nothing in a month you miss the tier.
If you want to see how the One Card lines up against rivals from other banks on rate, cap and minimum spend, our roundups of the best cashback credit cards in Singapore and the best grocery credit cards do the side-by-side.
| Feature | UOB One Card | Flat-rate card (e.g. UOB Absolute) |
|---|---|---|
| Headline rate | About 3.33% general, 5% to 6.67% on bonus merchants | 1.7% on almost everything |
| Minimum spend | S$600 to S$2,000 every month, 10+ transactions | None |
| Miss a month | Whole quarter's cashback forfeited | No effect, you still earn |
| Cashback cap | Bonus capped at S$120 per statement month | No cap |
| Best for | Steady, high, bonus-merchant-heavy spend | Lumpy or spread-out spend, no tracking |
This is a card for a specific spending pattern, not a default pick for everyone.
It suits you if your monthly card spend is steady and high enough to clear a tier every month, ideally Tier 2 or Tier 3, and a real chunk of it goes to Grab, Shopee, SimplyGo, McDonald's or supermarkets. It suits you even more if you also hold or want the UOB One Account, because the spend does double duty. A household charging most of its groceries, transport and food delivery to one card is close to the ideal user.
Skip it if your spending is lumpy, seasonal or below S$600 in any month, because one weak month forfeits the whole quarter's cashback. Skip it if you travel often or shop on overseas sites, where the 3.25% fee and the local-only bonus categories work against you. And skip it if you would rather not track three-month spending windows at all, in which case a flat-rate cashback card with no tier game, or simply a fixed deposit for idle cash, is the lower-stress choice.
The general rule for any cashback card still applies here: it only pays if you clear the statement in full every month. UOB charges roughly 27.8% a year in interest on purchases if you carry a balance, which wipes out a 3.33% rebate many times over. Set the full balance to pay by GIRO and the cashback stays clean.
It is worth it if you can charge at least S$600 a month, ideally S$2,000 for the top tier, in every month of a quarter and your spending leans toward Grab, Shopee, SimplyGo, McDonald's or groceries. At Tier 3 you get about 3.33% on everything plus 5% to 6.67% on those merchants. If your spend is lumpy or under S$600 in any month, you forfeit the whole quarter, and a flat-rate card or savings account does better.
The standard ongoing rate is about 3.33% on general spend at any of the three tiers, because the spend and the payout scale together. Selected merchants (Grab, Shopee, SimplyGo, McDonald's) earn 5% on Tier 1 and 2 and 6.67% on Tier 3. The base rate if you miss every tier is just 0.03%. The 'up to 10%' or 'up to 20%' figures include a new-customer promo for the first quarter only.
You need to spend at least S$600 in each of the three statement months in a quarter, with at least 10 transactions per month, for the S$60 tier. S$1,000 a month earns S$100, and S$2,000 a month earns S$200. You must hit the bar in all three months; missing one month means no quarterly cashback at all, apart from a pro-rated payout in your first quarter.
The standard rate on Shopee, Grab, SimplyGo and McDonald's is 5% on Tier 1 and 2 and 6.67% on Tier 3. The 10% figure comes from a new-to-UOB Enhanced Cashback promo (15 May to 30 September 2026 application window) that adds an extra layer for the first quarter only, and only if you qualify for Tier 3. After that you drop back to the standard rates. All bonus cashback is capped at S$120 per statement month.
The annual fee is S$196.20, waived for the first year. The first supplementary card is free and the second onwards is S$98.10 each. UOB will often waive the fee on request if you have spent regularly through the year, so it is worth calling before you pay.
Singaporeans and permanent residents need a minimum annual income of S$30,000, and foreigners need S$40,000. You must be at least 21 years old to hold a principal card. Your credit limit is capped by MAS rules based on income, which apply across all banks.
Yes, 3.25% on overseas and foreign-currency transactions, including online purchases billed in a foreign currency. The bonus categories are local merchants only, so the card is a weak choice for travel or overseas shopping; the fee usually outweighs the cashback you earn abroad.
They are different products designed to pair. The One Card pays cashback on spending; the One Account pays bonus interest, currently up to 1.90% a year on balances up to S$150,000, if you spend at least S$500 a month on an eligible card and credit a salary of at least S$1,600. If you want both the interest and the cashback, using the card to meet the account's spend requirement makes the spend do double duty. If you only want one, judge each on its own merits.
On the standard ongoing terms the most you can earn in a quarter is S$560: the S$200 flat cashback at Tier 3 plus the bonus on selected merchants, which is capped at S$120 per statement month, or S$360 across the quarter. That works out to S$2,240 a year if you max out every quarter. Hitting the bonus cap is hard in practice because it needs more than S$5,000 a quarter through Grab, Shopee, SimplyGo, McDonald's, groceries or SP utilities, so most cardholders earn well under the ceiling.
Quarterly cashback is credited after your qualifying quarter ends, once UOB confirms you met the minimum spend and transaction count in all three statement months. A quarter is three consecutive statement months counted from your card opening date, not the calendar quarter. The tiny 0.03% base cashback, if you earned no quarterly cashback in a calendar year, is paid the following February.
A flat-rate card like the UOB Absolute pays about 1.7% on almost everything with no minimum, no tiers and no cap. The One Card pays a higher headline rate but only if you clear a tier in all three months of a quarter and spend on its bonus merchants. The One Card wins on steady, high, bonus-heavy spending; the flat-rate card wins on lumpy or spread-out spending, because 1.7% on everything beats a forfeited quarter.
Singaporeans and PRs aged 56 and above need a lower minimum income of S$15,000 a year rather than S$30,000. If you cannot meet the income bar at all, UOB issues the One Card on a secured basis against a fixed deposit of at least S$10,000, a route older applicants and those between jobs sometimes use. The cashback terms are the same on a secured card.
