With Interest Rates Down, Is it Time to Revisit UOB Lady’s 6 to 10 Miles Per Dollar?
The first time I looked at UOB Lady’s higher earn rates of 6 to 10 miles per dollar, it was quite a different climate for interest rates. OCBC 360 still gave 4.65% p.a. back then, and UOB One was offering up to 4% p.a. of effective interest. Even fuss-free accounts were offering at least 3% p.a. interest, making the opportunity cost for funds too high for funds to be left in the 0.05% p.a. UOB Lady’s Account.
It’s almost exactly 2 years since UOB started linking higher earn rates on its UOB Lady’s Card with how much balance one maintains in their UOB Lady’s Savings Account. Since then, interest rates have dropped significantly, so I think it’s worth taking another look at whether we should look at maintaining funds with UOB Lady’s Savings Account to boost the earn rates of our UOB Lady’s Card.
Opportunity cost of using UOB Lady’s Savings Account versus a HYSA
Despite rates falling over the past 2 years, there are still a few high-yield accounts that offer interest rates higher than 3% p.a., provided you can meet their various requirements. The number of high-yield savings accounts (HYSA) that can comfortably offer this rate, however, has dwindled significantly. At present, only OCBC 360, DBS Multiplier, and StanChart Bonus$aver can offer higher than 3% p.a.
I’ll use Bonus$aver’s 3.35% p.a. to compare against UOB Lady’s 0.05% p.a. interest rate to derive the opportunity cost of going for UOB Lady’s Account:
| Monthly Average Balance | Interest at 0.05% p.a. | Opportunity Cost (3.35% p.a.) |
|---|---|---|
| S$10,000 | S$0.42 | S$27.50 |
| S$50,000 | S$2.08 | S$137.50 |
| S$100,000 | S$4.17 | S$275 |
Outside of HYSA, the opportunity cost is a lot lower
Those who have maxed out their HYSAs (or can’t meet the requirements) and are using fuss-free accounts for excess cash savings would find putting some savings into UOB Lady’s Savings Account even more worthwhile.
With many accounts failing to hit even 1.5% p.a., the opportunity cost of putting funds in one’s UOB Lady’s Account is lower than before:
| Monthly Average Balance | Interest at 0.05% p.a. | Opportunity Cost (1.5% p.a.) |
|---|---|---|
| S$10,000 | S$0.42 | S$12.08 |
| S$50,000 | S$2.08 | S$60.42 |
| S$100,000 | S$4.17 | S$120.83 |
UOB Lady’s Card with a spend cap of S$1,000
For those with UOB Lady’s Card, bonus miles are given on only on the first S$1,000 of spend. Depending on the monthly average balance of the UOB Lady’s Account, you can get bonus a maximum of 2,000 to 6,000 miles (on top of the 4,000 you get from the usual 4 miles per dollar earn rate).
Since you are forgoing interest by placing funds in your UOB Lady’s Savings Account, you can derive the cost per mile by dividing the opportunity cost by the number of bonus miles you’d get:
| Monthly Average Balance (of UOB Lady’s Savings Account) | Cost Per Mile (forgoing 1.5% p.a.) | Cost Per Mile (forgoing 3.35% p.a.) |
|---|---|---|
| S$10,000 | 0.60¢ 🟢 | 1.38¢ 🟢 |
| S$50,000 | 1.51¢ 🟠 | 3.44¢ 🔴 |
| S$100,000 | 2.01¢ 🔴 | 4.58¢ 🔴 |
Here, we are assuming that one maxes out the S$1,000 spend of UOB Lady’s Card. For the first time yet, even a high-yield savings account is struggling to provide better value than UOB Lady’s Savings Account.
UOB Lady’s Solitaire: maxing out your S$1,500 spend? Even higher tiers make sense
For those with the Solitaire version and can max out their S$1,500 spend cap (S$750 × 2 categories), all three tiers can make sense:
| Monthly Average Balance (of UOB Lady’s Savings Account) | Cost Per Mile (forgoing 1.5% p.a.) | Cost Per Mile (forgoing 3.35% p.a.) |
|---|---|---|
| S$10,000 | 0.40¢ 🟢 | 0.92¢ 🟢 |
| S$50,000 | 1.01¢ 🟢 | 2.29¢ 🔴 |
| S$100,000 | 1.34¢ 🟢 | 3.06¢ 🔴 |
If you’re maxing out your UOB Lady’s Solitaire, you would be able to get pretty good value from all 3 tiers compared to a 1.5% p.a. account. Even the S$10,000 tier makes sense compared to a HYSA like Bonus$aver.

Summary
In summary, due to the lower interest rates in mid-2026, placing funds in UOB Lady’s Savings Account for a higher earn rate on UOB Lady’s Card is now a lot more attractive than before.
Thanks to lowered rates, even high-yield savings account may make less sense if you are a heavy spender on UOB Lady’s Card. Of course, it depends very much on your actual spending, interest rate you can get outside, and your perceived value of miles, so use the calculator above to help you decide whether it makes sense.
