HDB Loan vs Bank Loan — Which Should You Pick?
Two loan options, completely different risk profiles. HDB loan is the safe bet — stable rate, lower down payment, total flexibility. Bank loan is cheaper right now but comes with rate risk. Here's how to decide for 2026.
Quick answer: HDB loan charges 2.6% fixed with 80% LTV (lower down payment, all CPF OK). Bank loan is currently ~1.1% (SORA-based) with 75% LTV (5% must be cash). Bank loan saves you money right now, but the rate floats — and it hit 4%+ in 2023-2024. The critical catch: you can switch from HDB to bank anytime, but you can never switch from bank to HDB.
Head-to-head comparison
| Factor | HDB Loan | Bank Loan |
|---|---|---|
| Interest rate | 2.6% (pegged) | ~1.05-1.30% (SORA) |
| Rate type | Effectively fixed | Floating (resets quarterly) |
| LTV | 80% | 75% |
| Down payment | 20% (all CPF OK) | 25% (5% cash + 20% CPF) |
| Max tenure | 25 years | 25 years |
| Prepayment penalty | None | 1.5% during lock-in |
| Lock-in period | None | 2-3 years typical |
| Refinancing | Can switch to bank | Cannot switch to HDB |
| Eligibility | SC/PR, income ceiling | Anyone who qualifies |
Interest rates — the big difference
HDB loan: 2.6% and stable
HDB pegs the concessionary interest rate at the CPF Ordinary Account rate + 0.1%. The CPF OA rate has been 2.5% since July 1999, making the HDB loan rate 2.6% for over 25 years. It is not contractually fixed — HDB could theoretically change it — but they never have. For practical purposes, you can treat it as fixed.
Bank loan: ~1.1% now, but it moves
Bank home loan rates are typically pegged to the 3-month compounded SORA (Singapore Overnight Rate Average) plus a spread. As of Feb 2026, most packages sit around 1.05-1.30%. That is significantly cheaper than HDB's 2.6%.
But rates move. In 2022, SORA-based packages were under 1.5%. By late 2023, they spiked past 4%. In 2025-2026, rates came back down as the Fed cut. The point: what you sign up for today is not what you pay forever.
The math on a $400K loan, 25 years: At 1.1%, your monthly payment is about $1,530. At 2.6%, it is about $1,810. That is a $280/month difference — $3,360/year — in favour of the bank loan right now. But if bank rates rise to 4%, your payment jumps to $2,111, and suddenly you are paying $301/month more than the HDB loan.
Down payment — where cash matters
On a $500K HDB flat:
| Component | HDB Loan | Bank Loan |
|---|---|---|
| Loan amount | $400K (80%) | $375K (75%) |
| Down payment | $100K (20%) | $125K (25%) |
| Cash required | $0 | $25K (5%) |
| CPF usable | $100K (all of it) | $100K (remaining 20%) |
This is a real differentiator for younger buyers. If your CPF OA has $100K but your bank account is thin, the HDB loan lets you avoid touching cash entirely. The bank loan forces $25K in cash out of your pocket.
Refinancing — the one-way door
HDB loan to bank loan: You can do this anytime. No penalty, no restriction. If bank rates drop and you want to save on interest, you refinance to a bank package. Many HDB loan holders did exactly this when SORA was under 1% in 2021.
Bank loan to HDB loan: Not possible. Ever. HDB concessionary loans are only available at the point of flat purchase. Once you take a bank loan, you are locked into the bank ecosystem permanently. You can refinance from one bank to another, but you cannot go back to HDB.
Why this matters: Starting with an HDB loan gives you optionality. You can always switch to a bank loan later if rates are favourable. Starting with a bank loan means you absorb all the rate risk with no escape hatch back to HDB's 2.6%.
When HDB loan wins
You are risk-averse and want predictability. You know exactly what you pay every month for 25 years. No rate surprises, no stress when the Fed raises rates. Sleep-at-night peace of mind.
You have limited cash savings. The zero-cash down payment is a big deal. If putting $25K cash toward a flat would clean out your emergency fund, the HDB loan keeps your cash buffer intact.
You are a first-time buyer and unsure about rates. Starting with HDB gives you optionality. If bank rates drop to crazy lows again, you can always refinance later. You keep the option open without committing to rate risk from day one.
You plan to hold long-term (10+ years). Over a long horizon, interest rate cycles will hit you. SORA will go up and down. The HDB loan's stable 2.6% means you never have to worry about rate spikes eating into your budget during a bad year.
When bank loan wins
SORA is low — like right now. At ~1.1% vs 2.6%, you save about $280/month on a $400K loan. Over the typical 2-3 year lock-in period, that is $6,720-$10,080 in savings. Real money.
You have a healthy cash buffer. The 5% cash component is not a strain. You have 6+ months of expenses saved beyond the down payment. Rate fluctuations will not force you into financial stress.
You plan to sell within 5 years. Shorter holding period means less exposure to rate cycles. You collect the savings at low rates and exit before a potential spike. Just time your sale to clear the lock-in period.
You are comfortable managing refinancing. Every 2-3 years when your lock-in expires, you shop for a new bank package. This takes effort — comparing rates, doing paperwork, paying legal fees (~$2,000-$3,000). If you are the type to stay on top of this, you can consistently capture low rates.
Common misconception: the "hybrid strategy"
I see this advice online all the time: "Start with a bank loan when rates are low, then switch to an HDB loan if rates spike." Sounds clever. There is just one problem — it does not work.
You cannot switch from a bank loan to an HDB loan. Full stop. HDB concessionary loans are only available at the point of purchase. There is no mechanism to convert a bank loan to an HDB loan later, no matter how high bank rates go.
The actual hybrid strategy that works is the opposite: start with an HDB loan, then refinance to a bank loan when rates are low. You capture the optionality of the HDB loan (stable fallback) while being able to jump to cheaper bank rates when the market is favourable. When your bank lock-in expires and rates have risen, you are already on a bank loan and cannot go back — but at least you entered with the safer option and chose to switch on your own terms.
Bottom line: The real hybrid is HDB first, bank later. Never the other way around. Anyone telling you to start with a bank loan and switch to HDB later either does not understand the rules or is selling you a bank package.

Can I switch from a bank loan to an HDB loan?
No. This is a one-way door. You can refinance from an HDB loan to a bank loan anytime with no penalty. But once you take a bank loan, you cannot switch to an HDB loan — ever. HDB loans are only available at the point of purchase. This is one of the most important things to understand before choosing.
Is the HDB loan interest rate really fixed?
It is pegged at CPF OA rate + 0.1%, which has been 2.6% since July 1999. Technically HDB can change it, but they never have in over 25 years. It is not contractually fixed like a fixed-rate bank package — it is a policy rate that HDB sets. Most people treat it as effectively fixed, and historically that has been correct.
What happens if SORA goes back to 4%?
Your monthly payment increases significantly. On a $400K loan over 25 years, going from 1.1% to 4% raises your monthly payment from about $1,530 to $2,111 — that is $581 more per month or nearly $7,000 more per year. This happened in 2023-2024 when SORA spiked. If you are on a bank loan and rates rise, your options are to absorb the higher payments, refinance to another bank package, or pay down principal faster. You cannot switch to an HDB loan.
Can I partially prepay my HDB loan or bank loan?
HDB loans allow partial prepayment anytime with zero penalty. You can pay any amount, any time — no minimum, no fee. Bank loans typically have a lock-in period of 2-3 years. During lock-in, prepayment incurs a penalty of 1.5% of the amount prepaid. After lock-in, most banks allow penalty-free prepayment. Always check your bank loan letter of offer for the exact terms.
Which loan is better if I plan to sell within 5 years?
Bank loan usually wins for short holds. You pay less interest at current SORA rates (saving roughly $200-300/month on a $400K loan), and you only need to ride out the rate risk for a shorter period. Just make sure your sale timing clears the bank lock-in period to avoid prepayment penalties. Also remember MOP — you cannot sell your HDB until you have lived in it for 5 years.
Do I need to use CPF or cash for the down payment?
For HDB loans, the 20% down payment can be paid entirely with CPF — no cash needed. For bank loans, the 25% down payment must include at least 5% in cash (for HDB flats). The remaining 20% can come from CPF. This 5% cash requirement is a key differentiator and can be a dealbreaker for buyers with limited cash savings.
