HDB Loan Calculator Singapore 2026

The HDB concessionary loan rate is 2.6% per annum as of 2026, reviewed quarterly. It is pegged at 0.1% above the CPF Ordinary Account interest rate. Bank loans may offer lower promotional rates (from ~2.0% for fixed-rate packages) but, like HDB loans, currently require a 25% minimum downpayment (LTV capped at 75% since 20 Aug 2024) — for a bank loan, at least 5% of that must be in cash. HDB loans remain more accessible for buyers with limited cash savings because the full 25% downpayment can come from CPF OA.

With SGD 5,000 monthly income and no other debts, your maximum monthly housing instalment under MSR (30%) is SGD 1,500. Under TDSR (55%), your maximum total debt burden is SGD 2,750. With zero existing debt, the MSR limit binds first. At 2.6% over 25 years, you could borrow approximately SGD 325,000. Since the loan is capped at 75% LTV, that loan implies a flat price of roughly SGD 433,000 (with the remaining 25% as downpayment). Adding SGD 500/month in car loan payments reduces your maximum affordable loan and flat price.

For an HDB concessionary loan, the minimum downpayment is 25% of the purchase price (LTV capped at 75% since 20 Aug 2024). This can be paid entirely from your CPF Ordinary Account savings if your balance is sufficient — no cash is required. Bank loans also require a 25% minimum downpayment, but at least 5% of that must be in cash. For a SGD 500,000 flat, an HDB loan requires SGD 125,000 downpayment (all via CPF OA if available), versus the same SGD 125,000 for a bank loan, of which at least SGD 25,000 must be cash.

Three caps apply simultaneously and the strictest one wins: (1) HDB maximum tenure of 25 years. (2) Age cap — your age plus loan tenure cannot exceed 65. If you're 45, maximum tenure is 20 years. (3) Lease cap — remaining lease minus loan tenure must be at least 20 years. For a 99-year lease flat with 50 years remaining, maximum tenure is 30 years, but capped further to 25 years by HDB rules. If you're 50 and the flat has 40 years remaining: age cap = 15 years (65-50), lease cap = 20 years (40-20), HDB cap = 25 years. Result: 15-year maximum tenure.

MSR (Mortgage Servicing Ratio) caps your monthly HDB loan repayment at 30% of gross monthly income. TDSR (Total Debt Servicing Ratio) caps all your debt obligations (housing + car loans, personal loans, credit cards, study loans) at 55% of income. Both must be satisfied. Example: Income SGD 8,000, car loan SGD 500/month. MSR allows up to SGD 2,400 for housing. TDSR allows up to SGD 4,400 total debt (SGD 3,900 for housing after car loan). MSR binds at SGD 2,400. With 2.6% over 25 years, max loan = SGD 520,000. For a SGD 500,000 flat with 10% downpayment (loan SGD 450,000), monthly instalment would be SGD 2,040, well within the SGD 2,400 MSR limit.

Yes. The CPF OA portion of your monthly CPF contribution (the split varies by age band — see CPF's published allocation table) can be used to pay your HDB instalments. If your CPF OA contribution for the month is less than the instalment, you pay the difference in cash; if it's more, the surplus stays in your OA earning interest. Note that using CPF OA for housing reduces the balance available for retirement, so consider your long-term CPF position before maximising housing usage.

HDB loans are generally better if: (1) You have limited cash savings — the 25% downpayment can be paid entirely from CPF OA, whereas a bank loan requires at least 5% in cash, (2) You want flexibility (partial prepayment without penalty), (3) You're buying a BTO flat (CPF housing grants available). Bank loans may be better if: (1) You can secure a significantly lower rate than the 2.6% HDB rate, (2) You want a longer loan tenure (up to 30 years for private property versus HDB's 25-year cap). Rule of thumb: if you don't have cash on hand for a downpayment, an HDB loan is the more accessible choice.

Several CPF housing grants are available for eligible buyers: Enhanced CPF Housing Grant (up to SGD 80,000 for families, SGD 40,000 for singles) based on income; Family Grant (up to SGD 50,000 for resale flats near parents); Proximity Housing Grant (up to SGD 30,000 for living near parents); Singles Grant (up to SGD 25,000 for eligible singles buying resale). These grants are credited to your CPF OA and can reduce your loan amount. Our calculator does not auto-apply these — use them to reduce the property price input.

Singles (aged 35+) can buy a 3-room or smaller BTO flat or any size resale flat with an HDB loan. The MSR/TDSR limits are the same. Singles receive lower CPF housing grants (about half of family grants). Permanent Residents (PRs) can buy resale HDB flats but not BTO. PRs must meet a 3-year residency requirement. The loan rules (MSR 30%, TDSR 55%, 2.6% rate) apply the same regardless of residency status, though PRs may face slightly stricter income assessment.

HDB requires that the remaining lease at the end of your loan tenure is at least 20 years. For a flat with 40 years remaining lease, and you're 35 years old, the maximum possible tenure is 20 years (40-20), not 25. This is often more restrictive than the age cap (65-35=30) or HDB's 25-year maximum. Resale flats with shorter leases are cheaper but harder to finance. For flats with fewer than 30 years remaining, HDB may not offer a loan at all. Always check the remaining lease before making an offer.
