Singapore's big three banks—DBS, OCBC, and UOB—all offer savings accounts that promise substantially higher interest rates than the base rate of 0.05 percent. The catch? The rates aren't simple. Each account layers multiple bonus tiers based on what you do that month: whether you credit your salary, spend on their credit card, buy insurance or investments, or hit savings milestones. Most comparison articles just list the headline rates. This one shows you the maths for three realistic Singaporean financial profiles, so you can calculate which account wins for your situation.
How Bonus Savings Accounts Actually Work
All three banks use the same underlying mechanism: a base rate (essentially zero), topped with conditional bonuses. The bonuses stack or tier based on how many "categories" of transactions you complete each month. The magic is in understanding what each bank counts as an eligible transaction—because that's where people get tripped up and end up in the wrong account.
The base interest rate across all three is roughly 0.05 percent per annum. That pays almost nothing. The bonus is where your real return hides. To unlock it, you need to stack multiple activities: crediting your salary via GIRO, spending on the bank's credit card, buying insurance or investment products, or hitting monthly savings growth targets. The more conditions you meet, the higher your effective rate—but it caps at a balance threshold, typically between S$50,000 and S$100,000 depending on the bank.
Every bank defines eligible transactions differently. A S$500 spend might count fully for one bank, be capped at S$1,500 for bonus calculation at another, or not qualify unless it's on a specific card product. Always verify current conditions on each bank's website before opening an account.
DBS Multiplier Account 2025
DBS Multiplier is the most complex of the three. It works by counting how many eligible transaction categories you hit in a single month, then applying a tiered bonus based on the total volume.
The bonus tiers (indicative 2025 rates) are:
With one active category—salary crediting alone—you earn approximately 1.8 percent per annum on the first S$50,000. Meeting two categories (salary plus credit card spending of around S$2,000) bumps this to roughly 2.2 percent. Three or more categories, with higher transaction volumes, can reach 4.1 percent per annum on the first S$50,000. Any balance above S$50,000 earns the base rate of 0.05 percent.
To trigger each category, the requirements are straightforward: your salary must be credited via GIRO; credit card spending should exceed certain thresholds (typically S$500 to S$2,000 depending on target tier); additional bonuses unlock with home loan payments, insurance purchases, or investment products. DBS also allows its digital banking card (the DBS Digibank) transactions to count as card spend, which is useful if you don't have a traditional credit card.
DBS Multiplier makes sense if you earn a solid salary, are willing to concentrate your card spending in one place to hit volume thresholds, and have a DBS home loan or investment account to unlock the highest tier. The account also supports joint holders, which can be handy for couples who want to double their bonus reach.
OCBC 360 Account 2025
OCBC 360 takes a different approach: instead of tiering, it stacks bonus layers independently. Each bonus is separate, and you earn them in parallel rather than needing to hit all of them simultaneously.
The bonus structure works like this. A salary bonus of 2.0 percent applies if you credit a salary of at least S$1,800. A spend bonus of 0.6 percent kicks in when you spend S$500 or more on the OCBC credit card. A save bonus of 1.2 percent applies if your balance increases by at least S$500 compared to the previous month. An insure/invest bonus of 1.2 percent activates when you buy eligible products like life insurance or unit trusts. For large balances above S$75,000, a grow bonus layer adds extra yield. All bonuses apply to your first S$100,000.
This independence is powerful. You don't need insurance or investments to earn the salary and save bonuses. You can get 3.2 percent on your S$50,000 balance just by crediting a salary and growing your balance by S$500 each month—without needing the insure/invest tier. That structure appeals to savers who like predictability and don't want to be forced into products they don't need.
OCBC 360 is the winner for consistent savers: anyone who regularly deposits money and takes home a modest salary. It's also excellent for couples where only one spouse earns the salary—the non-earning spouse's salary bonus tier is covered, and they can still earn the save bonus independently.
UOB One Account 2025
UOB One is the simplest of the three. It uses a straightforward tier system: if you meet the monthly card spend requirement and credit your salary, you unlock a higher rate. The account also splits your balance into three separate S$25,000 buckets, each earning the same tiered rate up to S$75,000 total.
The headline rate is 3.85 percent per annum on your first S$75,000 if you spend at least S$500 on the UOB credit card and credit your salary that same month. If you only spend without salary crediting, the rate drops to roughly 1.0 percent. Spending more than S$2,000 monthly unlocks a marginally higher tier on your first bucket. Any balance above S$75,000 earns 0.05 percent.
The critical point with UOB One: the card spend threshold resets every calendar month. Miss it in a single month, and you lose the bonus tier for that entire month until you spend S$500+ again in the next period. This makes it less forgiving than OCBC 360, where missing one bonus layer doesn't erase your others.
UOB One suits reliable spenders who know they'll consistently hit that S$500 monthly threshold and want the simplest structure. It's also a good choice if you're a couple and can pool card spending on one cardholder to meet the S$500 minimum.
Head-to-Head Examples for Three Financial Profiles
Profile A: Fresh Graduate, S$3,500 Salary, S$400/Month Spend, S$30,000 Savings
DBS Multiplier: You'd be in the one-category tier (salary only), earning about 1.8 percent on S$30,000 = S$540 annual interest. To get higher, you'd need to force S$500+ card spend consistently.
OCBC 360: You earn 2.0 percent salary bonus + 1.2 percent save bonus (if you grow your balance by S$500 monthly) = roughly 3.2 percent effective on S$30,000 = S$960 annual interest. The save bonus is achievable even on a modest salary—just deposit S$500 more than last month.
UOB One: Your card spend is only S$400, below the S$500 threshold, so you'd earn base rate plus no meaningful bonus. Annual interest: negligible.
Winner: OCBC 360. The save bonus layer rewards consistent savers without requiring high card spending, making it ideal for a fresh graduate building an emergency fund.
Profile B: Mid-Career, S$6,000 Salary, S$1,500/Month Spend, S$60,000 Savings
DBS Multiplier: You hit the two-category tier (salary + card spend of S$1,500), earning approximately 2.8 percent effective on S$50,000 = S$1,400 annual interest, plus S$50 on the S$10,000 above threshold = S$1,450 total.
OCBC 360: Salary bonus (2.0%) + spend bonus (0.6%) + save bonus (1.2%) = 3.8 percent effective on S$60,000 = S$2,280 annual interest. The save bonus assumes you grow your balance by S$500 most months, which is reasonable on a S$6,000 salary.
UOB One: You exceed the S$500 spend + salary = 3.85 percent on S$60,000 = S$2,310 annual interest.
Winner: UOB One (by a narrow margin). Simplicity combined with strong rates for regular spenders. OCBC 360 is a close second if you're less consistent with the S$500 monthly growth.
Profile C: Couple, S$10,000 Combined Salary, S$2,500/Month Spend, S$100,000 Savings
DBS Multiplier: You're in the three-category tier with high transaction volume (3+ categories, with salary and card spend of S$2,500+). This earns roughly 4.1 percent on S$50,000 = S$2,050 annual interest, plus 0.05 percent on the S$50,000 above = S$25 = S$2,075 total. The S$50,000 cap is a real penalty at this savings level.
OCBC 360: All bonuses apply: salary (2.0%) + spend (0.6%) + save (1.2%) + grow bonus for balances above S$75,000 (additional 0.5%+) = combined roughly 4.5 percent effective on S$100,000 = S$4,500 annual interest. The S$100,000 cap is generous for larger savers.
UOB One: Capped at S$75,000. The first S$75,000 earns 3.85 percent = S$2,888 annual interest. The remaining S$25,000 earns 0.05 percent = S$12.50 = S$2,900 total.
Winner: OCBC 360. For high balance holders, the larger S$100,000 cap and grow bonus layer make it significantly ahead. You're earning S$1,600 more annually than UOB One.
"The difference between 0.05% base rate and 3.5% bonus on S$50,000 is S$1,725 per year—or S$144 every month. That's a free dinner for two just for crediting your salary to the right account."
Which Account Should You Choose?
The decision tree is straightforward once you know your own habits. If your savings are below S$30,000 and you value consistency over earning the absolute maximum, OCBC 360 wins because the save bonus layer doesn't require high card spending. You get rewarded for simply growing your balance month over month.
If you have mid-range savings (S$30,000 to S$75,000) and maintain reliable S$500+ monthly card spend, UOB One offers simplicity and strong rates. No forced insurance products, no balance thresholds to worry about until S$75,000. The tradeoff is that missing your S$500 spend threshold one month stings.
If your savings exceed S$75,000 or you want the highest possible rate regardless of the effort, OCBC 360 is the clear winner. The S$100,000 cap and grow bonus layer are unmatched.
High earners with DBS home loans and complex banking relationships might prefer DBS Multiplier for the integration, but most Singaporeans will find OCBC 360 or UOB One simpler and more rewarding.
Bonus interest rates change quarterly or annually. The rates shown here are indicative of 2025 conditions. Before moving accounts, always check the current rate tiers directly on each bank's website. A S$500 difference in annual interest doesn't justify switching if you're not confident about future rates.
What About Interest You're Leaving on the Table?
Here's the motivating math: holding S$50,000 in a base-rate account paying 0.05 percent nets you S$25 per year. Moving that same S$50,000 to a bonus account paying 3.5 percent earns you S$1,750 per year. The difference is S$1,725—or S$144 per month. That's equivalent to two decent dinners for two Singaporeans per month, every month, forever, just for credit card spend and salary crediting discipline.
The reason more Singaporeans don't optimize their savings accounts is simple: the effort feels disproportionate to the gain. Opening a new account, switching direct deposits, learning three different structures—it seems like friction. But the friction lasts maybe one hour. The reward is permanent.
Tax Considerations
Bank interest earned in Singapore is not subject to income tax for residents. This differs from some countries where savings interest gets taxed as ordinary income. So the interest you earn on these accounts is yours to keep, no further tax filing required. This is one of Singapore's genuine advantages for savers.
Comparing to Other Options
You might be wondering: should I just buy Singapore T-bills or Singapore Savings Bonds (SSB) instead? The answer depends on your time horizon. Bonus savings accounts are fully liquid—your money is accessible the same day if you need it. T-bills and SSB typically lock up your money for 6 to 12 months, though often at comparable or slightly higher rates than the savings accounts. Use savings accounts for your emergency fund and money you might need within six months. Use T-bills and SSB for money you're definitely not touching for the next year.
CPF Special Account rates (currently 4.0 percent plus an extra 1.0 percent government bonus) beat these savings accounts, but CPF is illiquid until age 55 and earmarked for retirement. Not comparable for day-to-day emergency fund purposes.

Frequently Asked Questions
Can I hold all three accounts at the same time?
Yes. You can open DBS, OCBC, and UOB savings accounts simultaneously, and there's no law against having multiple bonus accounts. However, you can only credit your salary to one bank per month via GIRO. The strategic move for couples is often to split: one spouse uses DBS Multiplier, the other uses OCBC 360 or UOB One, so you're earning maximum bonuses across both salary and spending.
What happens if I miss the card spend threshold one month?
It depends on the bank. UOB One resets completely—if you don't hit S$500 spend in a calendar month, you earn base rate for that entire month. OCBC 360 is more forgiving: you lose the spend bonus layer for that month, but your salary and save bonuses remain active. DBS Multiplier drops you to a lower tier based on however many categories you did complete.
Is the bonus interest taxable in Singapore?
No. Bank interest, including bonus interest, is not taxable for Singapore residents. You earn it, you keep it.
Should I choose these over other vehicles like T-bills or fixed deposits?
It depends on your timeline and risk tolerance. Bonus savings accounts are fully liquid—you can withdraw tomorrow if life changes. T-bills lock funds for 6-12 months at comparable or slightly better rates. Fixed deposits offer higher guaranteed rates but typically require longer lock-up periods (1-3 years) and give you less flexibility. For emergency funds, savings accounts win. For money you know you won't touch for 12 months, T-bills can be better. Combine them: emergency fund in a bonus savings account, next year's money in T-bills.
Will these rates stay the same?
No. Banks adjust bonus rates quarterly or annually based on competition and market conditions. The rates in this article are representative of early 2026 conditions but should not be assumed permanent. Before switching banks, verify the current rates and tiers directly on each bank's website. A rate change can shift the winner—for example, if OCBC 360 cuts its save bonus from 1.2 percent to 0.8 percent, the calculus changes dramatically.
