The Structural Differences First
Most buyers frame this as a rate comparison. That is accurate but incomplete. HDB loan and bank loan differ across six structural dimensions, and the "right" answer depends on which constraint matters most to your household.
| Feature | HDB Concessionary Loan | Bank Loan (2026) |
|---|---|---|
| Interest rate | 2.6% p.a. (fixed formula) | 1.45 to 1.7% fixed (2yr); 1.7 to 1.9% (3yr) |
| LTV BTO | 90% (5% cash + 5% cash/CPF) | 75% (5% cash + 20% cash/CPF) |
| LTV Resale HDB | 80% (20% cash/CPF) | 75% (5% cash + 20% cash/CPF) |
| Rate stability | Pegged to CPF OA + 0.1%; stable since 1999 | Fixed for 2 to 3 years, then floating |
| Switching out | Can switch to bank loan anytime, no penalty | Lock in penalty (1.5%) during fixed period |
| Switching back | N/A (you start here) | Cannot return to HDB loan once you leave |
| CPF OA minimum | No minimum OA balance required | Must maintain $20,000 OA (for HDB properties) |
| Eligibility gate | Income ceiling $14K (family), $7K (single), SC ownership required | No income ceiling |
Real Example: Woodlands BTO Couple HDB vs Bank Loan on a $480,000 Loan
| Detail | HDB Concessionary Loan | Bank Fixed 2Y at 1.6% |
|---|---|---|
| Profile | SC couple, household income $9,500/month. Buying Woodlands BTO at $520,000. CPF OA (combined): $60,000. | |
| BTO purchase price | $520,000 | $520,000 |
| LTV | 90% → borrow $468,000 | 75% → borrow $390,000 |
| Minimum cash downpayment | 5% = $26,000 (cash) | 5% = $26,000 (cash) |
| Balance downpayment (CPF/cash) | 5% = $26,000 (CPF OA) | 20% = $104,000 (CPF OA or cash) |
| CPF OA available | $60,000 covers 5% easily | $60,000 covers only $60K of $104K needed; $44K shortfall |
| Monthly instalment (25yr) | $468K @ 2.6% = $2,121/month | $390K @ 1.6% = $1,669/month during fixed period |
| Monthly saving during fixed period | Baseline | $452/month saving × 24 months = $10,848 saved |
| After 2 year fixed period (SORA ~1.5%) | 2.6% unchanged | ~3.1% all-in floating = $1,873/month (still saves $248/month) |
| 10 year total interest cost | ~$95,400 | ~$73,200 (at avg 2.0% for 10yr) |
| 10 year net saving | Baseline | ~$22,200 saving but only achievable if $44K CPF shortfall is bridged with extra cash savings |
| Verdict | Right choice for this couple: CPF OA is insufficient for bank loan's 20% down at BTO | Would be optimal but CPF balance creates a cash crunch at collection |
This couple should take the HDB loan. At $9,500/month income with only $60K CPF OA, they cannot comfortably meet the bank loan's 20% downpayment without depleting emergency cash. The HDB loan's 90% LTV removes this barrier. They can always switch to a bank loan after MOP once CPF OA has rebuilt.
Monthly Payment Comparison on a $400,000 Loan
The table below compares actual monthly payments at 25 year tenure across the HDB rate and two bank fixed rate scenarios.
| Loan Amount | HDB 2.6% (25yr) | Bank Fixed 1.55% (25yr) | Bank Fixed 1.75% (25yr) | Monthly Saving (Bank vs HDB) |
|---|---|---|---|---|
| $300,000 | $1,359 | $1,199 | $1,240 | $119 to $160 |
| $400,000 | $1,812 | $1,599 | $1,653 | $159 to $213 |
| $500,000 | $2,265 | $1,999 | $2,066 | $199 to $266 |
| $600,000 | $2,718 | $2,398 | $2,479 | $239 to $320 |
Bank savings apply only during the 2 to 3 year fixed period. After that, SORA pegged rates apply currently around 1.5 to 2.0% in 2026, below HDB's 2.6%, but subject to change with interest rate cycles.
HDB Loan Eligibility in 2026
To qualify for an HDB concessionary loan, all criteria must be met:
- At least one buyer must be a Singapore Citizen
- Monthly household income: ≤$14,000 (family), ≤$7,000 (single under 35), ≤$14,000 (joint singles)
- No private property owned in the last 30 months
- Buying an HDB flat (BTO or resale)
- No outstanding HDB loan on another flat
- Property value ≤$800,000 for resale (no cap for BTO)
8 Scenarios and the Right Call for Each
Scenario 1 Income near the ceiling ($12K to $14K)
Bank loan. You qualify for HDB loan but your income is high enough that the rate savings are meaningful and you can absorb rate resets. Save the $150 to $250/month difference and refinance strategically at every fixed period end.
Scenario 2: Income below $6K, limited savings
HDB loan. The 80 to 90% LTV means lower cash required upfront, and the rate stability protects against payment shock if rates rise. The HDB loan's rate has been 2.6% since 1999; that is a form of insurance.
Scenario 3: Plan to sell within 5 years (after MOP)
Bank loan, but only if you lock the sale before the fixed period ends. If you can sell within your 2 year fixed period, you save on interest and exit before the floating rate kicks in. Coordinate sale timing with lock in expiry.
Scenario 4: Single buyer, income borderline for TDSR
HDB loan. The higher LTV (80% for resale) reduces the loan amount needed, making TDSR easier to pass. Bank loan requires 25% down payment. That extra 5% cash or CPF could be decisive for a cash light buyer.
Scenario 5: Both spouses have strong stable incomes
Bank loan. Refinance risk is low because dual income provides buffer. Take the rate savings, build CPF, and refinance every 2 to 3 years at prevailing best rates. This is the financially optimal path for dual income professional households.
Scenario 6: Near retirement, one income dropping soon
HDB loan. Rate stability matters more than savings when future income is uncertain. Locking in 2.6% for life (with no reset risk) beats a 1.6% fixed rate that floats to 3.5% when the earning spouse retires.
Scenario 7 High CPF OA balance
Bank loan worth considering. With strong CPF, you can handle the higher down payment (bank loan requires 25% vs HDB's 80% coverage), and the lower rate means more CPF savings accumulate at 2.5% OA interest rather than being consumed by higher mortgage payments.
Scenario 8: Buying a resale flat above $600K
Model both. The HDB loan caps LTV at 80% (so you borrow $480K on a $600K flat), while a bank loan at 75% means borrowing $450K. The $30K less borrowed via bank partially offsets the higher down payment requirement. Run the total cost with the expected holding period.
