HDB Loan vs Bank Loan Singapore 2026: Which Saves More?

For most Singapore HDB buyers, the choice between an HDB concessionary loan and a bank loan is the single largest financial decision attached to the flat purchase. Get it right and you save tens of thousands of dollars in interest. Get it wrong and you either pay too much or — worse — find yourself unable to absorb a payment shock when interest rates move.

This guide compares the two loan types in detail, with worked numbers using current 2026 rates, and explains exactly when each option wins.

The Two Choices, Side by Side

The HDB loan is a subsidised product designed to help citizens onto the property ladder. The bank loan is a commercial product priced off market interest rates.

How the HDB Rate Works

The HDB concessionary rate is pegged at 0.1% above the CPF Ordinary Account interest rate. The CPF OA rate has a statutory floor of 2.5% per annum and has not moved off that floor since 1999. The result: an HDB loan rate that has stayed at 2.6% for more than two decades and is structurally insulated from market volatility.

This stability is the HDB loan's defining feature. You can plan your household budget for 25 years knowing exactly what your repayment will be.

How Bank Rates Work

Bank home loans in Singapore are priced off one of three reference rates:

• SORA (Singapore Overnight Rate Average) — the dominant benchmark since SIBOR was phased out. Most floating-rate packages use 3-month compounded SORA plus a spread.
• Fixed Deposit Rate (FDR) packages — the bank's published fixed deposit rate plus a spread. These tend to be sticky on the way down.
• Board rate — the bank's discretionary internal rate. Generally avoid: it can change without prior notice.

Banks also offer fixed packages of 2 to 5 years, after which the loan reverts to a floating rate. In the elevated-rate environment of 2023, fixed packages briefly hit 4% per annum. By mid-2025 they had eased back to 2.5% – 3.0%, and 2026 packages are pricing around 2.5% to 2.8% for 2-year fixed.

Worked Example: S$400,000 Loan Over 25 Years

We compare three scenarios at the same loan size and tenure.

Scenario A — HDB loan at 2.6% for 25 years

• Monthly repayment: S$1,814
• Total interest paid: S$144,200

Scenario B — Bank loan, 2.6% fixed for 3 years, then 3.0% floating for 22 years

• Monthly repayment (yrs 1–3): S$1,814
• Monthly repayment (yrs 4–25): rises to ~S$1,889
• Total interest paid (estimate): ~S$152,000

Scenario C — Bank loan, 2.6% fixed for 3 years, then 4.0% floating for 22 years

• Monthly repayment (yrs 1–3): S$1,814
• Monthly repayment (yrs 4–25): rises to ~S$2,108
• Total interest paid (estimate): ~S$200,000

Scenario C — a perfectly plausible outcome if SORA stays elevated — costs S$56,000 more than the HDB loan over the life of the mortgage. That is the cost of rate risk.

The flip side: if you refinance every 2 to 3 years to chase the lowest rate and rates stay low, Scenario B-style outcomes can save S$10,000 to S$20,000 versus the HDB loan.

The Down Payment Difference

For a S$500,000 flat:

Since the HDB LTV was aligned with bank LTV in August 2024 (both 75%), the loan size is the same under either route — but the bank loan still requires 5% cash. If you do not have S$25,000 in cash savings, the bank loan is simply not available to you regardless of the headline rate. That is the most common reason first-time buyers default to the HDB loan even when bank rates are lower.

When the Bank Loan Wins

A bank loan is the better choice when:

• Bank fixed rates are clearly below 2.6% and you can lock in for 3 to 5 years
• You have at least 5% of the price in cash plus reserves for fees
• You are buying a larger or more expensive flat where small rate differences compound into meaningful dollars
• You are comfortable refinancing every 2 to 3 years and willing to monitor SORA
• Your household income comfortably clears TDSR with stress-tested rates at 4%

When the HDB Loan Wins

The HDB loan is the better choice when:

• You are CPF-rich but cash-poor and want to put zero cash down
• You value payment certainty over potential savings — useful for single-income households or careers with variable bonuses
• Your flat is on the smaller side (S$300,000 to S$450,000 loan) where the absolute interest difference is modest
• You expect interest rates to rise or stay elevated
• You want no refinancing admin for the next 25 years

A Sensible Default Strategy

For most first-time HDB buyers, the pragmatic move is:

1. Take the HDB loan at the start. Zero cash down, predictable payments, no admin.
2. Watch bank fixed rates. When 2-year fixed packages drop materially below 2.6% (say 2.2% or lower) for a sustained period, refinance to a bank loan.
3. Lock in for 3 to 5 years when refinancing. Avoid floating rates unless you have the financial bandwidth to absorb a SORA spike.
4. Re-evaluate every refinancing window. If bank rates rise above 2.6% again, you stay put — you cannot switch back to HDB, but you can ride out the cycle.

This sequencing captures the HDB loan's optionality while still giving you the upside if commercial rates fall.

Bottom line

The HDB loan is the safer default — stable, flexible, and accessible to CPF-funded buyers. The bank loan rewards buyers with cash, market awareness, and a willingness to refinance. Run the numbers on your specific loan size and tenure before committing.
