The cheap interest personal loans you see advertised in Singapore lead with a flat rate like 0.90% or 1.00% p.a. That number is real, but it is not the price you pay. A flat rate charges interest on your whole original loan for the full tenure, even on money you have already repaid. The figure that tells the truth is the Effective Interest Rate (EIR), and for the cheapest bank loans in 2026 it runs from roughly 1.75% to 3.30% p.a. once fees and the repayment schedule are baked in. This guide ranks the actual low-cost options by EIR, shows you the fees the headline rate hides, and tells you when a 0.90% loan quietly becomes a worse deal than a 1.48% one.
Every personal loan in Singapore is sold on a flat (or applied) rate. If you borrow S$10,000 over 12 months at 1.00% p.a. flat, the bank charges S$100 of interest, even though your average outstanding balance over the year is closer to S$5,000. You are paying interest on money you no longer hold. That is why the flat rate always looks about half the real cost.
The Effective Interest Rate corrects for this. It folds in the processing fee, the compounding, and the timing of your monthly repayments, which is why MAS and every bank are required to publish it. As a rule of thumb in Singapore, the EIR lands somewhere near double the flat rate for a one-to-five-year loan. So a loan marketed at 1.00% p.a. flat is really around 1.9% to 2.0% p.a. EIR; a 1.48% flat loan is around 3.2%. Compare loans only on EIR. The EIR is the apples-to-apples number; the flat rate is the marketing one.
Two loans can share a flat rate and still cost differently. A loan with a 1% processing fee at 1.00% flat is pricier than one at 1.00% flat with zero processing fee, because the fee is financed and inflates the EIR. Always read the EIR line, then check the processing fee separately.
Below are the bank and digital-bank loans with the lowest published EIRs, verified against each provider's own page as of June 2026. Rates shown are the lowest advertised tiers; your actual offer depends on your income, credit profile, and tenure. Promotions and cashback are time-limited and change monthly, so treat any cashback figure as 'as of June 2026' and confirm on the provider's site before applying.
Standard Chartered's CashOne wins the headline EIR at 1.75% p.a., but that figure is quoted on a 5-year tenure and excludes the first-year S$199 annual fee, so the true cost for a small or short loan is higher than it looks. CIMB and GXS are the cleaner low-cost picks because both charge zero processing fee, and GXS adds no early-repayment or late fees at all.
| Lender | Flat rate p.a. (from) | EIR p.a. (from) | Processing fee | Min. annual income (SG/PR) | Notable catch |
|---|---|---|---|---|---|
| Standard Chartered CashOne | 0.90% | 1.75% | Nil on loan | S$30,000 | EIR quoted on 5-yr tenure; S$199 first-year annual fee |
| UOB Personal Loan | 1.00% | 1.93% | Nil | S$30,000 | Best EIR needs longer tenure |
| CIMB Personal Loan | 1.00% | 1.94% | S$0 | S$20,000 | Min loan S$2,000; 21-70 yrs |
| GXS FlexiLoan | 1.08% | 2.02% | S$0 | S$20,000 | Interest charged daily on outstanding balance |
| Trust Bank Instant Loan | 1.00% | 2.28% | S$0 | S$30,000 | App-only; S$200-S$20,000 |
| HSBC Personal Loan | 1.30% | 2.50% | Nil | S$65,000 | Income bar raised to S$65k from Oct 2025 |
| DBS / POSB Personal Loan | 1.48% | 3.22% | 0% (rebated) | S$20,000 | Higher EIR but low income bar |
The cheapest EIR is not always the cheapest dollar cost, because tenure changes everything. A longer tenure lowers your monthly repayment but raises total interest paid. Here is what S$10,000 looks like across realistic 2026 scenarios, using the flat-rate method banks apply.
Stretching a loan to chase a lower advertised rate often backfires: you pay more interest in total even at a 'cheaper' rate. Before you commit, run your own numbers and stress-test the monthly repayment against your budget. Our personal budget calculator shows whether the monthly figure fits, and the financial health calculator flags if you are already over-leveraged.
| Flat rate | Tenure | Total interest | Monthly repayment | Total repaid |
|---|---|---|---|---|
| 1.00% p.a. | 1 year | S$100 | ~S$842 | S$10,100 |
| 1.00% p.a. | 3 years | S$300 | ~S$286 | S$10,300 |
| 1.48% p.a. | 3 years | S$444 | ~S$290 | S$10,444 |
| 1.00% p.a. | 5 years | S$500 | ~S$175 | S$10,500 |
The cheapest tiers are gated. Most banks want at least S$20,000 to S$30,000 in annual income; HSBC raised its bar to S$65,000 from 1 October 2025. Foreigners almost always face a higher threshold, often S$45,000 to S$90,000 plus a valid Employment Pass.
MAS caps your total unsecured borrowing across all banks at 12 times your monthly income, a limit in place since 2019. If you earn under S$20,000 a year, your total outstanding unsecured credit cannot exceed S$3,000. Your individual offer is usually 2x to 6x monthly income depending on what you earn. Education, medical, business, and renovation loans are exempt from these unsecured-credit rules.
The 'from' rate is for clean borrowers. A thin or blemished file pushes your offer up a tier or gets it declined. It is worth checking and improving your file before applying. See our guide to your credit score in Singapore for the levers that actually move it.
A personal loan is rarely the cheapest way to borrow. Depending on your situation, one of these beats it on cost.
If a bank declines you, the next stop is a licensed moneylender, not a personal loan. Under the Ministry of Law's Moneylenders Act, the maximum interest a licensed moneylender may charge is 4% per month on the reducing balance, the late fee is capped at S$60 a month, and the late interest is also capped at 4% a month on the overdue amount. That works out to an EIR far above any bank loan. Borrow there only as a last resort, and never from an unlicensed lender.
As of June 2026, Standard Chartered CashOne advertises the lowest EIR at 1.75% p.a., but that is quoted on a 5-year tenure and excludes a S$199 first-year annual fee. For loans with zero processing fee and no hidden annual fee, CIMB (EIR from 1.94%) and GXS FlexiLoan (EIR from 2.02%) are cleaner low-cost picks. Your actual rate depends on income, credit profile, and tenure.
The advertised flat rate charges interest on your full original loan for the entire tenure, even on the portion you have already repaid. The EIR corrects for this by accounting for your falling balance, the processing fee, and compounding. In Singapore the EIR is typically around double the flat rate, which is why you should compare loans on EIR rather than the headline number.
MAS caps total unsecured borrowing across all banks at 12 times your monthly income. Individual loan offers usually range from 2 to 6 times your monthly income, depending on what you earn. If your annual income is below S$20,000, your total outstanding unsecured credit across all providers cannot exceed S$3,000.
Often yes, if you can repay within the promotional window. A balance transfer offers 0% interest for a fixed period (commonly 3 to 12 months) with a one-off fee of around 1.5% to 5%. If you clear the debt before the promo ends, it usually costs less than a personal loan. If you cannot, the rate jumps sharply and a fixed-instalment personal loan may be safer.
