Savings Account Interest Calculator Singapore
Headline rates like "up to 7.35%" rarely apply to you. Enter your balance, salary and card spend, and see what 11 Singapore accounts would actually pay you in a year, ranked.
Split your money for the most interest
Most bonus rates stop at S$75,000 to S$150,000, so a big balance usually earns more spread across a few accounts. This works out the best split of your savings balance above, using your salary, card spend and GIRO bills. Your salary can only go to one bank, so it tries every combination.
What each account needs
Bonus accounts pay their best rates only when you hit monthly conditions. Here's what each one counts, as published by the bank.

Frequently asked questions
Which savings account pays the highest interest in Singapore?
It depends on your balance and habits. With a salary credit and card spend, bonus accounts like UOB One, OCBC 360 and DBS Multiplier usually pay the most on S$50,000 to S$150,000. With no salary credit or card spend, simple accounts such as Chocolate Finance (2% on the first S$20,000), GXS Saving Pockets (1.2%) or MariBank (0.88%) often pay more. The calculator ranks them for your exact situation.
How is UOB One interest calculated?
From 1 Dec 2025, UOB One pays tiered rates on your monthly average balance up to S$150,000. With S$500 card spend and a S$1,600 salary credit, you earn 1.00% on the first S$75,000, 2.50% on the next S$50,000 and 3.40% on the next S$25,000: S$2,850 a year (1.90%) on S$150,000. With card spend and 3 GIRO bills instead of salary, it's 1.00% and 2.00% on the first two tiers.
How is OCBC 360 interest calculated?
OCBC 360 pays 0.05% base plus bonuses on the first S$100,000 of your average daily balance. Salary (S$1,800+) earns 1.00% on the first S$75,000 and 2.00% on the next S$25,000. Save (grow your balance by S$500) earns 0.40%, raised to 0.50% and 1.10% until 31 Dec 2026. Spend (S$500 on eligible OCBC cards) adds 0.25%, and there are Insure, Invest and Grow bonuses on top.
Should I split my money across accounts?
Often, yes. Most bonus rates stop at S$75,000 to S$150,000, so money above the cap earns little. A common setup is a bonus account up to its cap, with the rest in T-bills, SSBs or a cash management account. The split planner above works out the best mix for your balance.
Are savings account interest rates guaranteed?
No. Banks can change rates at any time, and several bonuses here are promotions with end dates. Deposits with banks are insured by SDIC up to S$100,000 per depositor per bank. Chocolate Finance is not a bank and isn't covered by SDIC.

How this calculator works
Rates and conditions were captured from each bank's official product page and terms (UOB, OCBC, DBS, Standard Chartered, Bank of China, Maybank, CIMB, Trust, GXS, MariBank and Chocolate Finance) on 28 Oct 2026. We assume your balance stays the same all year, your salary is credited by your employer with the right code, and the card spend goes on that bank's eligible card. Promotional bonuses are applied until their end date and shown with an "ends" tag. Results are estimates; the bank's own calculation is final. Spot an error? Email dlcuration@gmail.com.
