UOB One card review: how $600, $1,000 and $2,000 a month really pay

The UOB One doesn't pay a percentage of what you spend. It pays a fixed amount each quarter, earned by three months in a row of hitting a spend level and a purchase count. The catch is that one short month can cost the whole quarter.

Here's how the cashback works, the rules on quarters and the 10 purchases, the extra cashback, the fees, and a worked year you can redo with your own numbers.

The UOB One at a glance

Figures from the UOB One terms (updated 22 Sep 2025, ver 2.1), the UOB One FAQ (updated 1 Nov 2026) and the product page, checked 1 Nov 2026. Promotions, including a time-limited overseas one on the product page, are left out here because they change often.

How does the UOB One cashback work?

Clause 3.1 of the terms sets three tiers. For each of the three statement months in a quarter, you need:

So it's per month and per quarter at once: the spend level is checked month by month, and the cashback is paid for the quarter.

The "up to 3.33%" in UOB's ads comes from the bottom of each tier: $600 × 3 = $1,800 of spending for $60, and $60 ÷ $1,800 = 3.33%. The same is true at $1,000 ($100 ÷ $3,000) and $2,000 ($200 ÷ $6,000).

Above the bottom of a tier, the cashback stays the same, so the rate falls:

Spending counts by statement month, by the date a purchase posts, not the date you made it (FAQ questions 1 and 8). Supplementary cards' purchases count too, under the terms' definition of card transactions.

Bottom line: the card pays for steady spending just above a tier. A month of $1,400 earns the same as a month of $1,000.

The 10 purchases, and the month that costs a quarter

Each statement month needs at least 10 card transactions, as well as the spend. And the quarter pays at the tier you met in all three months.

Say someone spends $1,200, $1,150 and $980 across a quarter, with plenty of purchases each month. The third month is under $1,000, so the quarter pays at tier 1: $60, not $100. That $20 shortfall costs $40.

With only 9 purchases in a month, or under $600, the quarter pays nothing (clause 3.2). The exception is the first quarter after you get the card, which can be pro-rated: one-third of the cashback if you only qualify in the third month, two-thirds if in the second and third. After that, the minimum must be met in full.

There's also a base cashback of 0.03% for the year, but only if you earned no quarterly cashback at all in that calendar year (clause 3.6). On $12,000 of spending, that's $3.60.

Bottom line: know your statement date. That's when each month closes.

Quarters start from your card, not from January

The terms define a quarter as three consecutive statement months, starting from the card account's opening date (clause 2). UOB's FAQ gives an example: a card issued in February has quarters of Feb to Apr, May to Jul, Aug to Oct and Nov to Jan.

Two people with UOB One cards can be in different quarters in the same month. The FAQ says your statement shows your qualifying quarters.

Bottom line: a quiet month in the same quarter can undo a big one.

The extra cashback on Grab, Shopee and groceries

Once you've qualified for a quarter's cashback, you also earn additional cashback on "Selected Merchant Transactions" (clause 4.1), worked out on each month's total and capped at $120 per statement month (clause 4.3):

UOB's ads add the 3.33% to these, which is where the "up to 10%" comes from. The quarterly cashback is fixed, and these are on top.

Groceries count only at tier 2 and above, and only at merchants coded as grocery stores or supermarkets. A shop's code is set by its bank, not UOB.

Singapore Power bills earn the 1% when charged to the card directly. The product page notes that payments through AXS don't count.

Bottom line: at tier 1, a monthly supermarket run earns no extra. Tier 2 is where the card starts paying for groceries.

What doesn't earn cashback, or count to the minimum

The exclusions in clause 6 earn nothing and don't count towards the monthly spend. As at 1 Nov 2026 they include: GrabPay and ShopeePay wallet top-ups; insurance, rent, tax, school and university fees, hospitals, parking, gambling, charities and government services (by merchant category code); payments through AXS, EZ-Link, CardUp, iPayMy, SingPost SAM and a list of brokers and payment services; instalment plans, cash advances, fees and interest.

UOB's FAQ (question 6) confirms insurance under MCC 6300 neither earns nor counts towards the minimum. Utilities aren't on this card's list, which is why Singapore Power can earn.

Bottom line: a big insurance premium won't help you reach $600 in the month it's due.

The fees, and when cashback arrives

The annual fee is $196.20, waived for the first year (product page). The first supplementary card is free. The second onwards is $98.10.

Cashback is credited in the statement after the quarter ends (clause 3.5), and it can only be used against the main cardholder's spending in the following statement month (clause 3.7). Unused cashback is forfeited 2 calendar years after the quarter it was awarded for, or when the card is cancelled (clause 3.9).

Bottom line: cancel before the last quarter's cashback has been credited and used, and you lose it.

How it compares, at a stated spend

What each card pays on a month of ordinary spending, with none of it at bonus merchants, as at 24 Oct 2026, from Sum's reading of each bank's terms:

UOB One's figures are the quarterly cashback divided by 3, and assume 10 purchases a month. The flat cards have no minimum or purchase count, so in a month you miss a tier, the UOB One column for that quarter can drop to the tier below, or to nothing. Each card has its own exclusions too.

A worked year

Say Kelvin is 30 and puts about $1,100 a month on the card, well over 10 purchases, including $120 on Grab, $300 at supermarkets and a $90 Singapore Power bill. Made-up example.

Over a year, that's $144.73 × 4 = $578.92 on $13,200 of spending, or about 4.4%. From the second year, the $196.20 fee brings it to $382.72.

Now say one month in one quarter dips to $980. That quarter pays at tier 1: $60, plus Grab $18 and Singapore Power $2.70, with no supermarket extra at tier 1: $80.70 instead of $144.73. A $20 dip costs about $64.

Bottom line: swap in your own months, and look at the lowest one, not the average. The calculator page does the same sums: UOB One on the card rewards calculator.

Three things to remember

1. $600, $1,000 or $2,000 every statement month, with 10 purchases, for a fixed $60, $100 or $200 a quarter. The lowest month sets the quarter.
2. Quarters start from your card's opening month. Your statement shows which months they are.
3. Extra cashback on Grab, McDonald's, Shopee, SimplyGo, supermarkets, Shell and Singapore Power only comes once you qualify, capped at $120 a month.

One person's opinion, from the terms in this review. Your own spending decides what a card is worth to you.

Track it in Sum

Import your card statements. The card tracker shows each month of the quarter with what it spent and how many purchases it had, so you can see where the month stands. Sum uses calendar quarters until it knows a card's opening month, which matters if your quarter starts mid-year.
