Should You Refinance Your HDB Loan to a Bank Loan?
An HDB loan has a concessionary rate tied to the CPF Ordinary Account rate, no lock-in and no penalty for early repayment. A bank loan may cost less, but it floats, usually carries a lock-in, and once you switch you cannot come back. Here is how to work out whether the saving is real.
Key Takeaways
- The HDB concessionary rate is pegged at 0.10% above the CPF Ordinary Account rate and is 2.60% a year for the fourth quarter of 2026. Bank rates depend on the package and the market.
- You can refinance an HDB loan to a bank loan at any time, subject to the bank's approval, but once you do you cannot refinance back to an HDB loan.
- An HDB loan has no lock-in and no early repayment penalty. Bank loans usually have a lock-in of around one to three years, with a penalty that CPF Board says can be around 1.5% of the outstanding loan.
- Legal and valuation fees must be recovered from the interest you save. The smaller the rate gap, and the sooner you may sell, the less likely that is.
- For an owner-occupied flat, MAS does not require an MSR or TDSR test when refinancing, but the bank's own credit assessment still applies.
If you took an HDB loan when you bought your flat, you are paying a rate that does not move with the bank market. At some point, usually when bank offers look cheaper, the question comes up: should I refinance my HDB loan to a bank loan? The honest answer is that it depends on whether a bank can beat the HDB rate by enough, for long enough, to repay the cost of switching. This guide sets out what each loan offers, what the rules say, and how to test the decision with your own numbers.
The short answer
Refinancing from an HDB loan to a bank loan is worth considering when a bank's all-in offer is clearly below the HDB concessionary rate, you expect to keep the loan for several years, and you could absorb the instalment rising if the bank rate floats up. It is usually not worth it when the gap is small, when you may sell or upgrade within a few years, or when a predictable instalment matters more to you than a lower headline rate.
Important to know
The figures and rules in this guide were checked against HDB, CPF Board and MAS on 6 October 2026. Rates and rules change, so confirm the current position before you act.
How the HDB loan and a bank loan differ
The HDB concessionary rate is pegged at 0.10% above the prevailing CPF Ordinary Account (OA) interest rate. It may be adjusted in January, April, July and October in line with CPF rate revisions, and it is 2.60% a year for both the third and fourth quarters of 2026.2 Bank loans work differently: rates are either floating, pegged to a benchmark such as the Singapore Overnight Rate Average (SORA), or fixed for a set period before reverting to floating.3
| HDB concessionary loan | Bank loan | |
|---|---|---|
| Interest rate | 0.10% above the CPF OA rate; 2.60% a year to 31 December 2026 | Floating, pegged to a benchmark such as SORA, or fixed for a period (usually one to three years) before reverting to floating |
| Does the rate move? | Reviewed each quarter in line with CPF rate revisions | Moves with the market, or at the end of any fixed period |
| Lock-in | None | Typically around one to three years |
| Repaying early | No penalty | Penalty within the lock-in; CPF Board says around 1.5% of the outstanding loan, varying by bank and package |
| Switching later | You can refinance to a bank at any time, subject to the bank's approval | You can reprice or refinance with another bank, usually after the lock-in. You cannot refinance back to an HDB loan |
To see how far bank rates can swing, CPF Board notes that some homeowners secured bank rates below 1.5% a year in 2020 and 2021, while rates for some borrowers exceeded 4% a year in 2022 and 2023.3 A bank loan can be cheaper than the HDB loan for a period and then cost more.
Refinancing is a one-way door
HDB allows you to refinance with a financial institution regulated by the Monetary Authority of Singapore (MAS), but not to move back to HDB afterwards.1 That is the part most worth pausing over. While you keep the HDB loan, a bank is always an option you can take up later, whenever rates move in your favour. Once you move to a bank, that choice is gone for good.
What refinancing really costs
The interest you save has to pay for the cost of switching. CPF Board lists the costs to factor in as legal fees, valuation fees and, where you are leaving a bank loan, possible clawbacks of subsidies or rebates from your first bank.3 Leaving an HDB loan carries no early repayment penalty, but two other costs are easy to overlook:
- The new loan's own lock-in. Most bank loans have one, typically around one to three years. If you repay early or refinance again within it, the penalty can be around 1.5% of the outstanding loan, depending on the bank and the package. On a S$300,000 loan, 1.5% is S$4,500.
- Time. HDB says refinancing takes about 6 to 8 weeks from the date of application, so ask the bank how long its offer stays valid.1
Important to know
What the rules say
Refinancing is treated differently from taking a new loan. According to MAS:4
- For an owner-occupied property, the Mortgage Servicing Ratio (MSR) and Total Debt Servicing Ratio (TDSR) are not required for a refinanced loan, but you must still meet the bank's credit assessment criteria.
- There is no regulatory loan-to-value limit on a refinanced housing loan. Banks can lend up to the amount outstanding if you pass their assessment.
- A tenure cap applies. For an HDB flat, the maximum is 30 years minus the number of years since the first housing loan was disbursed. A flat bought six years ago could therefore be refinanced over at most 24 years.
The process runs through your solicitor. Once the bank confirms the loan, your appointed solicitor submits the accepted Letter of Offer to your managing HDB Branch, which provides a redemption statement for the amount to be discharged on the completion date.1
A worked example
The figures below are illustrative only. They assume S$300,000 outstanding with 20 years remaining and S$3,000 of one-off switching costs, a round number chosen for the example rather than a typical quote. The bank rates are scenarios, not offers. On an HDB loan at 2.60%, the monthly instalment is about S$1,604.
| Bank rate | Monthly instalment | Compared with HDB loan | Time to recover S$3,000 of costs |
|---|---|---|---|
| 1.80% | S$1,489 | S$115 less | About 26 months |
| 2.20% | S$1,546 | S$58 less | About 52 months |
| 2.60% | S$1,604 | No difference | Never |
| 3.00% | S$1,664 | S$59 more | Not applicable |
| 3.40% | S$1,725 | S$120 more | Not applicable |
A bank rate has to sit well below 2.60% before the saving covers the cost of switching in a reasonable time, and the saving shrinks quickly as the gap narrows.
Floating rates make the picture less certain. Take a package at 2.0% for the first three years that then reverts to 3.6%. Over five years the cash paid to the bank is only about S$330 less than on the HDB loan, and the outstanding balance is about S$150 higher. After the assumed S$3,000 switching cost, the borrower is behind by roughly S$2,800, and once the rate resets the instalment is about S$116 a month higher than the HDB loan's.

When each choice tends to make sense
Staying with the HDB loan tends to make sense when
- Bank offers are only slightly below 2.60%, so switching costs take years to recover.
- A predictable instalment matters more to you than a possibly lower rate.
- You may sell or upgrade within the next few years, when a new lock-in could get in the way.
- You want to keep your options open, because a bank loan can be taken later but cannot be reversed.
Refinancing to a bank loan tends to make sense when
- A bank's all-in offer, after fees and any subsidy, is clearly below the HDB rate and you plan to hold the loan well past the break-even point.
- You have a large outstanding balance and a long remaining tenure, so the saving has time to build.
- You could comfortably absorb a higher instalment if the rate floats up after any fixed period.
- You are confident you would pass the bank's credit assessment, which still applies even though MSR and TDSR do not.
If you may sell or upgrade soon
Many owners ask this question around MOP, when an upgrade is also on the table, and the two decisions interact. A new lock-in sits awkwardly with a sale in the next few years, the process itself takes 6 to 8 weeks, and a penalty of around 1.5% of the outstanding loan can wipe out years of interest savings. If a sale is likely, work out what you would actually receive first. Our guides on estimating your sale proceeds, buying first or selling first and the costs of moving from HDB to a condominium show how the loan fits into the wider plan.
Refinancing changes your lender; it is not a sale. The CPF refund that returns the CPF you used, plus accrued interest, to your account applies when you sell or transfer the property, as explained in our guide to what happens to your CPF when you sell. And if you already have a bank loan whose lock-in is ending, the question is a different one, covered in repricing versus refinancing.
Questions to ask before you switch
- What is the rate in each year of the package, what does it float against, and what spread does the bank add?
- How long is the lock-in, and does the penalty apply if I sell the flat within it?
- Who pays the legal and valuation fees, is there a subsidy, and are there clawback conditions?
- What is the longest tenure available for my flat under the MAS cap, and what would my instalment be over a shorter tenure?
- What would my instalment be if the rate rose by one percentage point after any fixed period?
- How long will the process take, and for how long is your offer valid?
Final perspective
Refinancing an HDB loan is less about finding the lowest rate on a given day and more about deciding whether to give up a loan with no lock-in, no early repayment penalty and a rate tied to CPF, in exchange for a saving that has to be large enough, and last long enough, to justify the switch. Work out your break-even with real quotes, test what happens if the rate rises, and think about whether you may move within the next few years before you commit.
