HDB applies two ceilings and lends the lower one. The lime bar is the one that binds for you.

HDB lends you the lower of the two. Raising the other bar will not change your loan until it drops below your current limit.

Same flat, same income — two very different deals. Once you switch to a bank you cannot switch back.

Both loans lend the same amount.
On the bank loan you'd pay $306 more each month and need $27,500 as the regulatory cash minimum, excluding COV, CPF shortfalls and fees. Tenure can stretch to 30 years, but anything past 25 years drops the LTV to 55%.
Resale only. Funding allocations based on your calculator inputs and the budget below, not confirmed payment dates.
Planning estimate only. Confirm valuation, usable CPF, approved grants, ABSD and fee quotes before sharing with a customer. HPS and agent/other costs entered as $0 are excluded, not confirmed free. Existing property loans, short leases and CPF rules may reduce actual financing.
Selected bank loan estimate: $412,500. The schedule follows this amount unless you enter a lower planned loan. The age estimate above is a simple average, not an income-weighted bank/HDB assessment.
CPF, grants and transaction costs
Enter only the amount available after retained savings, CPF housing/lease limits and any age-55 retirement set-aside. Default $0 does not assume CPF is available.
Include housing and proximity grants once only. Do not repeat grants already included in your OA figure. Allocated to the purchase price, not fees.
Default 0% assumes no ABSD. An SPR first-property purchase is generally 5%. Joint-buyer profiles and HDB/marital remissions require confirmation with IRAS/your solicitor; no future refund is deducted here.
$3,000 is an editable placeholder budget, not a quote. Include GST/disbursements and confirm CPF eligibility.
Enter the CPF quote for the selected loan/cover. $0 excludes HPS; it does not mean no premium. Recheck when the loan changes.
Enter your agreed fee, not a presumed commission rate. $0 excludes this fee.
Include applicable mortgage duty, registration, insurance or other charges not already included. $0 excludes these costs.
OA is reserved for HPS first, then selected stamp/legal fees; the balance and approved grants fund the price. Any shortfall becomes cash. Actual CPF approval and payment timing must be confirmed.
Enter the resale price and valuation above before calculating the payment schedule.
Official rules checked 28 September 2026. Amounts remain subject to HDB, CPF, IRAS and lender approval. This schedule does not establish purchase or grant eligibility.
How the HDB loan limit is calculated
Your HDB loan is the lower of two limits. The first is the loan-to-value (LTV) cap: 75% of the flat price or valuation, whichever is lower. The second is the Mortgage Servicing Ratio: your monthly instalment cannot exceed 30% of gross household income. HDB tests that instalment at 3%, not the 2.6% you actually pay, so the income-based limit is slightly more conservative than the rate suggests.
Paying the remaining 25%
An HDB loan has no minimum cash percentage, but resale option and exercise fees must be paid in cash. Cash over valuation and any shortfall after usable CPF, approved grants and the actual loan also need cash. A bank loan in the 75% LTV tier requires at least 5% of the lower of price or valuation in cash; the 55% tier requires 10%, before COV and other costs. CPF use is subject to available balances and housing limits. For BTO flats the down payment is split between signing the Agreement for Lease and key collection — see our BTO down payment calculator for the exact schedule, and the BSD calculator for the stamp duty due on top.
Stretching your loan tenure to 30 years
An HDB concessionary loan is capped at 25 years (or less if it would run past age 65). If you want a longer tenure to lower your monthly instalment, a bank loan can stretch up to 30 years — but tenures beyond 25 years fall under a reduced 55% loan-to-value limit instead of 75%, so you'll need a larger down payment to compensate.
Protecting the loan
If you use CPF to service your HDB loan, you must be covered by the Home Protection Scheme. For a full affordability check across multiple borrowers and variable income, use the mortgage loan calculator.
