How this optimizer works
Each bank pays a tiny base rate (around 0.05% p.a.) on all balances, plus a bonus rate on a qualifying sliceof your balance when you hit its activity categories. The optimizer applies your inputs to each bank's specific tier logic and blends the rates across your assumed deposit balance (we default to 6× your monthly salary) to produce the effectiverate — the one that actually lands in your account, not the headline number on the bank's homepage.
Banks revise these tiers regularly. The calculator shows a last-verified dateso you know how fresh the numbers are. If you're opening an account today, always cross-check against the bank's live product page — link in the Sources section below.
Frequently asked
Which is better: DBS Multiplier, UOB One, or OCBC 360?expand_more
It depends on your profile. DBS Multiplier rewards salary + multiple categories (card, loan, insurance, invest) and suits users transacting $15,000+/month. UOB One wins for steady salary earners spending $500/month on its card — the tiered bonus on the first $150,000 of balance is the most generous for mid-sized balances. OCBC 360 stacks the most categories (salary, save, spend, insure, invest) but each category adds less, so it works best for users who can hit 4–5 categories.
How do the bank tier rates actually work?expand_more
Each bank assigns a bonus interest rate on top of a tiny base (usually 0.05% p.a.) and only pays it on a qualifying balance band. DBS caps bonus on the first $50,000 or $100,000 (depending on categories hit). UOB One steps bonus rates up in tranches of $75k / $125k / $150k. OCBC 360 caps bonus on the first $75,000 or $100,000. Above the cap you earn only the 0.05% base. The optimizer applies each bank's specific tier logic to your numbers.
Do I need to credit my full salary to qualify?expand_more
Yes — all three banks require salary credit via GIRO/PayNow to unlock their top tiers. Minimums are roughly S$1,600 (UOB One), S$1,800 (OCBC 360) and S$2,000 (DBS Multiplier). If you're self-employed or on freelance income, UOB One's 3-GIRO-debits alternative is often the only way in. The optimizer shows which bank's threshold you clear.
What happens to interest above the qualifying balance cap?expand_more
You earn the base rate of 0.05% p.a. on any balance above each bank's cap. So a $200,000 balance in DBS Multiplier under the Salary + 3 Categories tier earns ~4.10% on the first $100,000 and 0.05% on the next $100,000 — the effective blended rate is therefore about 2.07%, not 4.10%. The optimizer shows the blended effective rate, which is what actually lands in your account.
How often do these banks change their tier rates?expand_more
More often than people think. UOB One revised its rate schedule in December 2025; OCBC 360 announced changes effective 1 May 2026; DBS adjusts Multiplier bonus rates roughly every 12–18 months in response to SORA. Always re-check the bank's product page at the top of a decision — the optimizer's "last verified" date is your safety signal. Banks must give 30 days' notice before reducing published rates.
