How this planner works

Your budget is solved against three constraints simultaneously, and the binding one is named. Income: MSR caps the instalment at 30% of gross recognised income (variable income takes the standard 30% haircut; a bank loan also applies the 55% TDSR with your other debts). Funds: cash, CPF OA, and your self-declared grants must cover the downpayment beyond the 75% loan plus BSD. Cash floor: bank loans require 5% of the price in cash that CPF and grants cannot replace — the constraint that most often surprises buyers comparing the two loans.

We deliberately don't compute grants or eligibility ceilings: those turn on details only HDB's own assessment can confirm. Bring your grant total from HDB's official check, and this planner turns it into a budget. For the duties side, see the Buyer's Stamp Duty Calculator; if a condo is the longer-term plan, our upgrader analysis covers how today's flat shapes that move.

Already know your price? The Resale HDB Purchase Planner lays out the option fee, deposits, and the chronological order of every payment to key collection.

Frequently asked questions

How much can I borrow for an HDB resale flat?
The Mortgage Servicing Ratio caps your instalment at 30% of gross monthly income, assessed at 2.6% for an HDB loan (the CPF OA rate + 0.1%) or at least 3% for a bank loan, over a maximum 25-year tenure ending by age 65. A couple earning $6,000 a month supports roughly $397,000 of HDB loan. Loan-to-value is capped at 75% of price or valuation for both loan types.
HDB loan or bank loan — what actually differs?
Four things. Rate: HDB charges a stable 2.6%; banks price off market (and must assess you at a 3% floor). Cash: an HDB loan has no minimum cash component — the full downpayment can come from CPF and grants — while a bank loan requires 5% of the price in hard cash. Flexibility: HDB loans can be refinanced to a bank later, but not the reverse. Penalties: HDB has no early-repayment penalty.
How do CPF housing grants work in this planner?
You enter your own grant total from HDB's official eligibility tools — we deliberately don't estimate grants, because the amounts turn on income averages, citizenship mix, proximity to family, and first-timer status that only HDB's own assessment can confirm. Grants are disbursed into CPF and count toward your downpayment, but they cannot satisfy a bank loan's 5% cash component.
Is there an income ceiling for buying a resale flat?
There is no income ceiling to buy a resale flat. Ceilings apply to taking an HDB concessionary loan ($14,000 household for families — check HDB for your case) and to grant eligibility. High earners buying resale simply finance with a bank loan.
Does ABSD apply to an HDB purchase?
Effectively no — you must dispose of private property to buy an HDB flat, so the purchase is assessed as your only property. BSD applies as normal: $12,600 on a $600,000 flat.

Indicative only. HDB loan eligibility, grant amounts, and income ceilings are determined by HDB; bank financing is subject to approval under prevailing MAS rules. Not financial advice.
