HDB Loan vs Bank Loan: Which Is Cheaper in 2026?

Quick answer: A bank loan is cheaper right now. The lowest bank packages for HDB flats start at about 1.46% (floating) and 1.65% (two-year fixed), against 2.6% for an HDB loan. On a $500,000 loan over 25 years that is roughly $230 to $280 less every month. The HDB loan costs more but asks for less cash upfront, cannot spike, and leaves you free to move to a bank later. Once you take a bank loan, you can never go back to HDB.

Most comparisons of HDB loan vs bank loan stop at a feature table. This one puts dollar figures on the decision, because that is the part buyers keep asking us about.

What is the difference between an HDB loan and a bank loan?

The short version: an HDB loan trades a higher, steady rate for flexibility on cash, and a bank loan trades a lower, moving rate for a stricter cash rule and a one-way exit.

Sources for each row sit beside the figures below. A quick note on the jargon: LTV is the loan-to-value limit, MSR is the Mortgage Servicing Ratio, TDSR is the Total Debt Servicing Ratio, and SORA is the Singapore Overnight Rate Average that floating packages track.

What are HDB loan and bank loan interest rates in October 2026?

The HDB loan rate is 2.6% a year for the October to December 2026 quarter, and the cheapest bank packages for HDB flats sit about one percentage point lower.

The HDB concessionary loan rate is pegged at 0.1% above the CPF Ordinary Account rate. The Ordinary Account rate has a legal floor of 2.5%, and the CPF Board confirmed on 22 September 2026 that both rates stay unchanged for the quarter. In practice the floor makes 2.6% the lowest an HDB loan can go. It has sat there for years.

Bank rates are a different animal. As of 6 October 2026, the lowest HDB-flat packages at 1.46% floating (one-month SORA plus 0.20%) and 1.65% fixed for two years. Three-month compounded SORA was 1.23% at the time. These are indicative figures for a large loan, so your own quote may come in a little higher.

The history matters more than today's snapshot. The CPF Board notes that some bank rates fell below 1.5% in 2020 and 2021, then climbed past 4% in 2022 and 2023. Anyone who chose a bank loan in early 2022 paid more than HDB borrowers for a stretch of about two years.

Fixed or floating?

A fixed package locks your rate for one to three years, then usually reprices to a floating rate. A floating package moves with SORA from day one. Fixed costs a little more today and protects you from a jump during the lock-in. Floating is cheaper now and passes every rise straight to you. UOB's economists expect three-month SORA to drift up to about 1.40% by the end of 2026 and around 1.63% by the third quarter of 2027, per the same PropertyNet summary, which would still leave floating packages well under 2.6%.

Which is cheaper over 25 years? The numbers

On a $500,000 loan over 25 years, a bank loan at today's rates saves roughly $48,000 to $59,000 in interest compared with an HDB loan. A bank loan only ends up dearer if its average rate over the whole loan climbs above 2.6%.

Start with the monthly instalment at a flat rate:

Rates never sit still for 25 years, though. So we ran three paths a bank borrower could plausibly face:

Method: $500,000 loan, 25-year tenure, monthly rest, with the instalment recalculated at each rate change. These are illustrations, not loan quotes.

The third scenario is the one worth sitting with. Three straight years at 3.5% (close to what borrowers saw in 2023) only pulled the bank loan level with HDB. For the bank loan to lose by a clear margin, rates would have to stay high for most of the 25 years.

You can run your own loan amount and rate through our mortgage calculator to see where your break-even sits.

How much cash and CPF do you need upfront?

Both loans need a 25% down payment, but only the bank loan forces part of it into cash.

Take a $650,000 resale flat where the price matches the valuation. The down payment is $162,500.

With an HDB loan, the whole $162,500 can come out of your CPF Ordinary Account. HDB lets you keep up to $20,000 of Ordinary Account savings back, and anything above that goes into the purchase first, as the CPF Board explains.

With a bank loan, at least 5% of the price, $32,500 here, has to be paid in cash. The other 20% can be cash or CPF. If the bank stretches your tenure past 25 years, the MAS rules cut the loan to 55% and raise the cash portion to 10%.

That $32,500 is where many buyers decide. A couple with plenty of CPF and thin savings often cannot take the bank route at all, however good the rate.

One cost behaves the same under both loans. If you agree a price above the valuation, the gap is cash over valuation, and neither HDB nor the bank will lend against it. Neither will CPF.

Loan limits, tenure and eligibility

Both loans cap you at 75% of the price or valuation, whichever is lower, and both apply the 30% MSR to HDB flats.

HDB cut its own limit from 80% to 75% on 20 August 2024, bringing it in line with banks. Some older guides still quote 80% or a 20% down payment. Those figures are out of date.

Tenure is where the two split. An HDB loan runs for up to 25 years or until you turn 65. A bank can lend for up to 30 years on an HDB flat, but only at the lower 55% LTV once the tenure passes 25 years. For most first-time buyers, the longer bank tenure comes with a bigger cash outlay, so the lower instalment has a price.

To take an HDB loan you also need an HFE letter, and your household income has to sit under the ceiling. That ceiling rose to $16,000 for families and $8,000 for eligible singles for applications from 24 August 2026. We cover the details in our piece on the new $16,000 income ceiling. If you want to know how big a loan your income supports under each option, our guide on how much you can borrow works through it by salary.

Can you switch from a bank loan to an HDB loan?

No. You can move from an HDB loan to a bank loan at any time, but a bank loan can never be switched back to HDB. MoneySense, the government's financial education site, states this plainly.

This is the most important line in the whole comparison. Choosing HDB first keeps both doors open: you can refinance to a bank whenever its rates are clearly lower. Choosing a bank first closes the HDB door for good, so if SORA climbs to 2022 levels again, your only escape is another bank package.

Leaving a bank loan has its own costs. Breaking a lock-in usually costs about 1.5% of the outstanding loan, around $7,000 on a $500,000 loan two years in, and banks often claw back the legal subsidy if you refinance within the first few years. Moving from HDB to a bank is a separate decision with its own maths, which we will cover in a dedicated refinancing guide.

HDB loan or bank loan for BTO vs resale?

For a BTO flat, the choice rarely costs you anything to delay. For a resale flat, cash usually decides it.

BTO buyers wait years for keys, and the loan only starts at key collection. Today's 1.65% fixed rate tells you little about the rate you will get in 2029 or 2030. Many BTO couples keep the HDB loan route open at signing because it preserves the right to switch to a bank once the flat is ready and they can compare real offers.

Resale buyers face the cash question right away. Picture a couple buying that $650,000 flat with $40,000 in cash and $170,000 in CPF. A bank loan needs $32,500 of their $40,000 in cash, which leaves little for renovation, fees or any cash over valuation. An HDB loan lets them pay the down payment from CPF and keep their cash. A couple with $120,000 in cash and the same CPF can comfortably take the bank loan and pocket the monthly saving.

Which loan suits you if you plan to upgrade to an EC or condo?

If you plan to sell after the five-year Minimum Occupation Period (MOP), a bank loan's lock-in will usually have ended by the time you sell.

Lock-ins typically run two to three years. A five-year MOP outlasts them, so a bank borrower who sells after MOP normally pays no penalty. The one trap is refinancing into a fresh lock-in a year or two before you plan to list.

The next property is a different story. HDB loans exist only for HDB flats, so a new executive condominium or private condo from a developer has to be financed by a bank. Your next lender looks at your income and existing debts. Which loan you held on the flat makes no difference to that assessment. If you are already browsing new launches and ECs, the loan on your flat matters mainly for how much cash it leaves you at sale.

Should you choose an HDB loan or a bank loan?

Pick a bank loan if you have the 5% cash comfortably, can absorb a few years of higher instalments, and want the lower cost today. On current rates it is the cheaper loan.

Pick an HDB loan if your cash is thin, you want a fixed instalment you never have to monitor, or you are buying a BTO that will not be ready for years. You give up roughly $230 a month on a $500,000 loan, and in exchange you keep the option to switch.

The rule we would use: take the bank loan only if you would still be comfortable paying a 3.5% rate for three years. If that thought worries you, start with HDB and refinance once the gap is wide and your cash has grown.

Winnie's take

The buyers I see regret their choice fastest are the ones who picked a bank loan purely for the rate and then had no cash buffer when the valuation came in low. If your cash is tight, the HDB loan is the safer start. You can always move to a bank later. Message me on WhatsApp for more information on which loans fit your needs.

Common questions about HDB loans and bank loans

Is an HDB loan or a bank loan cheaper in 2026?

A bank loan is cheaper in 2026. The lowest bank packages for HDB flats start around 1.46% to 1.65% against HDB's 2.6%, which saves roughly $230 to $280 a month on a $500,000, 25-year loan.

Can I switch from a bank loan to an HDB loan?

No. Once you take a bank loan for an HDB flat, you cannot switch to an HDB loan later. You can only refinance to another bank package.

Can I switch from an HDB loan to a bank loan later?

Yes. You can refinance an HDB loan to a bank loan at any time, with no penalty from HDB. The decision is permanent, because you cannot return to an HDB loan afterwards.

How is the HDB loan interest rate calculated?

The HDB loan rate is the CPF Ordinary Account rate plus 0.1%. The Ordinary Account rate has a floor of 2.5%, so the HDB rate is 2.6% for October to December 2026 and is reviewed every quarter.

How much cash do I need for a bank loan on an HDB flat?

You need at least 5% of the price or valuation in cash for a bank loan at the 75% limit, and 10% if the tenure goes beyond 25 years. On a $650,000 flat, 5% is $32,500. Any cash over valuation is on top of that.

Can an EC buyer take an HDB loan?

No. HDB loans are only for HDB flats, so a new executive condominium bought from a developer has to be financed with a bank loan.

What happens if SORA goes up after I take a bank loan?

On a floating package your instalment rises at the next repricing, monthly or quarterly. On a fixed package nothing changes until the lock-in ends, after which the loan usually moves to a floating rate. A rise of one percentage point adds about $250 a month to a $500,000 loan.
