Almost every HDB buyer I speak with reaches for the same phrase: should I take the CPF loan or the bank loan. Correcting it can feel pedantic, except the wrong mental model leads to real decisions made on a false premise. This guide starts by fixing that, then works through every structural difference that should actually drive your choice, ending with an illustrative repayment comparison and, honestly, no recommendation, since that decision depends on your own numbers, not mine.
The naming confusion, cleared up first
There is no financial product called a CPF loan. What people mean is the HDB concessionary loan, a housing loan issued directly by HDB to eligible flat buyers at a rate pegged to CPF's own savings rate. The confusion is understandable because CPF sits so visibly inside the transaction: your CPF Ordinary Account can fund the downpayment and the monthly instalment on this loan. But CPF is not lending you anything. It is the pool of forced savings you are drawing down, whether you end up with an HDB loan or a bank loan.
There are two lenders in this comparison, HDB and a bank, and one funding source, your CPF Ordinary Account plus whatever cash you bring. A bank loan can also be paid using CPF Ordinary Account savings, subject to the CPF withdrawal limits that apply. The choice of lender and the choice of how you fund the repayment are two separate decisions that get bundled together in casual conversation, and untangling them is the first step to comparing the two loans properly.
Eligibility: who can even choose
The two loans are not always both on the table. The HDB loan is only available for buying an HDB flat, whether BTO, Sale of Balance Flats, or resale, and is not an option for private property or an Executive Condominium bought directly from a developer. Applicants must also satisfy HDB's eligibility conditions, including citizenship, an income ceiling, and owning no more than one other property at application, among other criteria that should be checked directly with HDB since they are revised over time.
Every flat buyer, regardless of which loan they eventually choose, now needs an HDB Flat Eligibility (HFE) letter before flat searching. It confirms your eligibility, any grant entitlement, and an indicative borrowing estimate from both an HDB loan and a bank loan, so you can compare like for like before committing.
A bank loan has wider reach: it can finance an HDB flat, an Executive Condominium, or private property, which is why buyers planning to sell an HDB flat and upgrade often think through their bank relationship early. For the wider eligibility picture on a bank loan for an HDB flat, see my home loan eligibility in Singapore guide.
Rate structure: a peg versus a market price
The HDB concessionary loan rate is set by a formula, not market sentiment. It is pegged at 0.1 percentage point above the prevailing CPF Ordinary Account interest rate. With the CPF OA rate at 2.5 percent, that gives the current HDB loan rate of 2.6 percent per annum. This peg has kept the HDB rate essentially unchanged for a very long time, which is the point of a concessionary loan: it is designed to be predictable, not to compete with the market every cycle.
Bank loans work differently. Packages are either fixed for an initial period, commonly a few years, or floating, and floating packages today mostly reference SORA, the Singapore Overnight Rate Average, as the benchmark. Illustrative bank mortgage rates currently sit around 1.5 percent, though this varies by bank, package, and loan quantum, and it will not stay static for the life of the loan. After any fixed period ends, or on a purely floating package, the rate moves with SORA and the bank's spread. That is the crux of the comparison: the HDB rate is stable but currently the higher of the two, and the bank rate is currently lower but not fixed for your full tenure.
The core trade off: certainty versus a lower starting rate
Strip away every other feature and this is what the comparison reduces to. The HDB loan offers a rate that has barely moved in decades, backed by a statutory board rather than a bank balance sheet, at the cost of currently being the more expensive option on paper. A bank loan offers a materially lower starting rate today, at the cost of accepting that the rate will reprice, potentially more than once, over a tenure that can run two or three decades.
Buyers who value knowing exactly what their instalment will be for the life of the loan, who have thin cash reserves, or who are risk averse about rate cycles tend to lean toward the certainty the HDB loan offers. Buyers comfortable managing a repricing loan, who want to minimise interest cost while rates are favourable, and who have a cash buffer for a future increase tend to lean toward a bank loan. Neither instinct is wrong; they are optimising for different things, and this is a judgment about your own risk tolerance and cash position, not a fact about which loan is objectively superior.
Loan to value and how much cash you actually need
This is where the two loans diverge most sharply, and it is often the deciding factor for buyers with limited liquid cash. A bank loan for a first housing loan currently allows financing of up to 75 percent of the property's value, its loan to value or LTV limit. Of the remaining downpayment, a portion must be paid in cash, with the rest payable from CPF Ordinary Account savings or cash.
The HDB loan's LTV limit is set separately by HDB and has historically allowed a higher proportion of the purchase to be financed, letting the downpayment be covered mostly or entirely from CPF, with little or no cash required. Because this limit is periodically reviewed, check the current HDB loan LTV limit and cash and CPF split directly with HDB or through your HFE letter before budgeting around it.
The practical effect: a buyer with strong CPF Ordinary Account balances but limited cash finds the HDB loan easier to fund upfront. A buyer with ample cash finds the bank loan's cash requirement a non issue and can focus purely on the rate and lock in trade off. For how CPF Ordinary Account funds interact with the downpayment, see my CPF OA versus cash downpayment guide.
| Dimension | HDB concessionary loan | Bank loan |
|---|---|---|
| Eligible property | HDB flats only (BTO, SBF, resale) | HDB flats, EC, private property |
| Rate basis | Pegged at CPF OA rate plus 0.1%, currently 2.6% p.a. | Fixed period then floats with SORA; illustrative around 1.5% p.a. |
| Cash requirement | Little or no cash; largely CPF fundable | Minimum cash portion required |
| Lock in / penalty | None | Typically a lock in period with an early redemption penalty |
| Switching | Can refinance out to a bank loan any time | Cannot switch into an HDB loan once on a bank loan |
Illustrative and general. LTV limits, bank rates, and lock in terms vary by package and change; verify current figures with HDB, your bank, and CPF.
Penalties and flexibility
The HDB loan carries no lock in period and no prepayment penalty. You can prepay partially or in full at any time without charge, useful if your income is irregular and you want the option to pay down the loan faster.
Bank loans typically carry a lock in period, commonly a few years from drawdown, during which redeeming the loan early, by refinancing elsewhere or paying it off in full, triggers a penalty on the outstanding amount. Some packages also claw back legal subsidies or other incentives if you exit within a specified window. Exact penalty percentages, lock in length, and clawback terms vary by bank and package and change over time, so treat any figure you hear as indicative only and confirm current terms in your bank's letter of offer before signing.
Switching: the one way door
This gets its own heading because it is the single most consequential, irreversible decision in the comparison, and the one buyers most often overlook. You can refinance from an HDB loan to a bank loan at any point, with no penalty from HDB. What you cannot do is go the other way: once you leave the HDB concessionary loan for a bank loan, that entitlement is spent, and you cannot switch back, even years later, even if bank rates have since risen well above the HDB rate.
This asymmetry is why the HDB loan functions as a form of insurance for buyers uncertain about their future rate risk tolerance. Staying on it costs the rate differential today but preserves the option to leave later on your own terms. Leaving it captures today's lower bank rate but permanently removes the fallback.
MSR, TDSR, and the stress test
Two affordability ceilings apply regardless of which loan you choose, since they are rules about your income, not features of a specific lender. The Mortgage Servicing Ratio caps your monthly mortgage repayment at 30 percent of gross monthly income and applies specifically to HDB flats and Executive Condominiums. The Total Debt Servicing Ratio caps all monthly debt obligations, mortgage plus car loans, credit card minimums, and other debt, at 55 percent of gross monthly income, across all property types.
The two loans differ in how the assessment is run. Bank loans apply a stress test interest rate floor, an assessment rate set above prevailing market rates, when computing MSR and TDSR headroom, so your approved quantum has a buffer against future rate increases. HDB's own assessment for its concessionary loan uses criteria tied to the concessionary rate. Either way, the ceilings exist to stop you over borrowing relative to income, and neither loan lets you sidestep them.
A worked illustrative comparison
The numbers below are entirely illustrative, round figures for a hypothetical $500,000 loan over a 25 year tenure, purely to show how the rate difference compounds. They are not a quote, do not reflect any actual bank package, and assume the bank rate holds for the full tenure, which in reality it will not, since bank packages reprice after any fixed period and floating rates move with SORA throughout.
| Scenario | Rate assumption | Illustrative monthly instalment | Illustrative total interest, 25 years |
|---|---|---|---|
| HDB concessionary loan | 2.6% p.a., held constant (realistic; the HDB rate has been stable for a long period) | Roughly $2,270 | Roughly $181,000 |
| Bank loan, illustrative | 1.5% p.a., held constant for all 25 years (unrealistic; see note below) | Roughly $2,000 | Roughly $99,000 |
Illustrative only, round hypothetical numbers on a $500,000 loan over 25 years. The bank scenario assumes the rate never moves, which is not realistic; a bank package reprices after any fixed period and floats with SORA thereafter. Treat the bank figure as a floor, not a forecast.
The honest reading is not that the bank loan saves roughly $82,000. It saves that much only if the rate never rises above 1.5 percent for 25 straight years, which has essentially never happened in Singapore's mortgage history. The real comparison is a known, stable 2.6 percent for the life of the loan against an unknown blended rate that starts lower but will likely average higher once you account for full cycles of repricing. Whether that trade is worth it depends on your own tolerance for uncertainty, not the arithmetic alone.
Who each option genuinely suits
These are considerations to weigh, not a recommendation, since the right answer depends on your income, CPF balances, cash reserves, and appetite for rate risk.
- The HDB loan tends to suit buyers with thin cash but healthy CPF Ordinary Account balances, first time buyers who want one less variable to manage, and anyone who values knowing their exact instalment for the life of the loan.
- A bank loan tends to suit buyers with cash on hand for the downpayment portion and any future rate increase, buyers comfortable actively managing and refinancing every few years, and buyers purchasing a property type the HDB loan does not cover.
- Either way, verify before committing. Your HFE letter, HDB, your CPF statement, and a mortgage adviser can confirm the exact figures for your flat and household, since conditions, LTV limits, and bank packages all change.
Frequently asked questions
Is the HDB loan the same thing as a CPF loan?
No. The HDB loan is a concessionary rate housing loan issued by HDB itself. CPF is not a lender, it is the savings scheme, your Ordinary Account, you draw from to make the instalment or downpayment on either an HDB loan or a bank loan. There is no separate product called a CPF loan.
Can I switch from a bank loan back to an HDB loan?
No. You can refinance from an HDB loan to a bank loan at any time, but the reverse is not available. Once you leave the HDB concessionary loan, that entitlement is used and you cannot return to it, even if bank rates later rise above the HDB rate.
What is the HDB concessionary loan rate and how is it set?
It is pegged at 0.1 percentage point above the prevailing CPF Ordinary Account interest rate. With the CPF OA rate at 2.5 percent, the HDB loan rate is currently 2.6 percent per annum, a peg that has kept it stable for a very long time, unlike bank rates which reprice with the market.
Do I need cash for a downpayment with an HDB loan?
With an HDB loan, the downpayment can typically be paid mostly or fully from CPF Ordinary Account savings, subject to HDB's applicable loan to value limit. A bank loan requires a minimum cash portion, with the rest payable from CPF or cash.
Does MSR or TDSR apply to an HDB loan?
Yes, both are income rules, not loan features. MSR caps mortgage repayments at 30 percent of gross monthly income for HDB flats and Executive Condominiums. TDSR caps all debt obligations at 55 percent of gross monthly income across property types. Bank loans additionally apply a stress test rate floor.
