Multiplier Account Optimizer

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.

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.

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.

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.

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.

Splitting is rarely better than concentrating, because each bank requires its own salary credit, spend and category fulfilment to unlock bonus rates. Crediting your salary into two banks at once is usually not possible (your employer pays into one account). The exception: if you and your spouse each credit a separate salary into a different bank, you can effectively double your bonus-interest cap as a household. Otherwise, pick the bank where your profile scores highest and put the qualifying balance there — overflow above the cap can sit in a Fixed Deposit or T-bill to earn more than 0.05%.

They count for different categories. The "spend" category at all three banks specifically means card spend on the bank's own debit or credit card — recurring GIRO bills do not count as card spend. However, UOB One has a separate "3 GIRO debits per month" alternative qualifier that lets non-salaried users (self-employed, freelancers) unlock bonus tiers without crediting a salary. Always check the bank's exact wording for the month you're trying to qualify in, because category definitions occasionally shift.

You drop down a tier for that month only — your bonus interest for the month is calculated under the lower tier, but you don't lose accumulated interest from prior months. Each bank assesses categories on a per-month basis. For example, if you normally hit Salary + Spend + Invest on OCBC 360 but skip an investment top-up one month, you earn the Salary + Spend tier rate for that month and revert when categories resume. This is why predictable, automatic activity (recurring invest plans, auto-pay credit card bills) is more effective than ad-hoc actions.
