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 1.9% to 3.2% 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.
Update, 13 October 2026: GXS now advertises its FlexiLoan from 2.88% p.a. (EIR 5.45%), up from the 1.08% (EIR 2.02%) this guide gave, and DBS charges a 1% processing fee, which this guide had as 0%. Trust Bank's 1.00% rate is for existing customers until 31 October 2026 and includes a 0.88% first-year annual fee. Below are the bank and digital-bank loans with the lowest published EIRs, verified against each provider's own page as of October 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 October 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; counting the fee, Standard Chartered puts the EIR at 2.15% for an average S$20,000 loan over five years. CIMB charges no processing fee on its 12 to 60-month tenures, and GXS charges no annual, processing, early repayment or late fees, though its advertised EIR is now 5.45% on a S$10,000 loan over two years.
| Lender | Flat rate p.a. (from) | EIR p.a. (from) | Processing fee | Min. annual income (SG/PR) | Notable catch |

| Trust Bank Instant Loan | 1.00% | 2.28% | S$0 (0.88% first-year annual fee, in the EIR) | S$30,000 | Existing customers, until 31 Oct 2026; 3% early repayment fee |
| HSBC Personal Loan | 1.30% | 2.50% | Nil (promo to 31 Dec 2026) | S$65,000 | Needs a Personal Line of Credit; S$30k bar if you hold S$50k with HSBC |
| DBS / POSB Personal Loan | 1.48% | 3.22% | 1% | 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 |
Update, 13 October 2026: this section had MAS's borrowing rules wrong. The S$3,000 cap for people earning under S$20,000 a year applies to licensed moneylenders; banks cannot grant those borrowers a personal loan at all. The cheapest tiers are gated. Most banks want at least S$20,000 to S$30,000 in annual income, and HSBC asks new customers for S$65,000. Foreigners face higher bars: S$42,000 at Citi, S$60,000 at DBS and Trust, S$65,000 at HSBC and S$90,000 with an Employment Pass at Standard Chartered. UOB and GXS lend only to citizens and PRs, and CIMB's foreigner tier is for Malaysians.
MAS caps your total interest-bearing unsecured borrowing across all banks at 12 times your monthly income, a limit in place since 1 June 2019. Banks can grant a non-card unsecured loan only if you earn at least S$20,000 a year. Each bank's limit is up to 2 months' income if you earn under S$30,000 and up to 4 months' income from S$30,000 to under S$120,000; above that there is no regulatory limit, and banks such as CIMB advertise up to 8 times. Education, medical, business and renovation loans are exempt from the minimum income rule.
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 October 2026, Standard Chartered CashOne advertises the lowest headline EIR at 1.75% p.a., but that is quoted on a 5-year tenure and excludes a S$199 first-year annual fee; with the fee, Standard Chartered puts it at 2.15% for an average S$20,000 loan. Counting fees, UOB (EIR from 1.93%) and CIMB (EIR from 1.94%) come out lower, with no processing fee on their longer tenures. 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 interest-bearing unsecured borrowing across all banks at 12 times your monthly income. Each bank can lend up to 2 months' income if you earn under S$30,000 a year and up to 4 months' income from S$30,000 to under S$120,000, with no regulatory limit above that. Banks cannot grant a personal loan if you earn under S$20,000 a year; the S$3,000 cap at that income applies to licensed moneylenders.
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.
