BTO / HDB affordability calculator

It depends on your income, savings and loan. As a rule of thumb your home loan repayment cannot exceed 30% of gross monthly income (MSR), with a bank loan your total debt cannot exceed 55% (TDSR), and you can borrow at most 75% of the price, so you need a 25% downpayment. Enter your numbers above for an estimate of the maximum flat price.

At least 25% of the price. With an HDB loan you can pay the whole 25% from your CPF Ordinary Account. With a bank loan, at least 5% of the price must be in cash and the other 20% can be CPF or cash.

The HDB concessionary loan is 2.6% per year (pegged to CPF OA + 0.1%), runs up to 25 years, and lets you pay the downpayment fully from CPF. A bank loan can be cheaper or pricier depending on rates, runs up to 30 years, but needs at least 5% of the price in cash. Both are capped at 75% loan-to-value; a bank loan over 25 years drops to 55%.

First-timer families can receive the Enhanced CPF Housing Grant (EHG) of up to $120,000, depending on income, plus other grants for resale flats (Family Grant, Proximity Housing Grant). Grants go into your CPF and increase your downpayment. Use HDB's grant calculator and apply for an HDB Flat Eligibility (HFE) letter for your exact amount.

From 24 Aug 2026: $16,000 a month for families, $24,000 for extended families, and $8,000 for singles. It was $14,000 for families before. Standard resale flats have no ceiling to buy (Plus resale: $16,000), but the resale grants and HDB loan do.

It is an estimate to help you plan, using current HDB, CPF and MAS rules. It is not a loan approval. Your actual loan depends on credit checks and the bank's or HDB's assessment, so confirm with them and apply for an HFE letter.

A popular rule of thumb: have at least 3 years of stable income before buying, keep the cash downpayment under 30% of your savings (so you keep a buffer), and keep the monthly repayment under 35% of household income. It's a sanity check on top of the official MSR (30%) and TDSR (55%) limits.

With an HDB loan, potentially none for the downpayment. It can all come from CPF OA. With a bank loan, at least 5% of the price must be cash. Either way, budget cash for the Buyer's Stamp Duty, legal fees, renovation, and (for resale) any Cash-Over-Valuation, which CPF and loans cannot cover.

First-timer households (never received a housing subsidy) get the most grants and priority in BTO ballots. Second-timers get fewer grants and may pay a resale levy when buying a second subsidised flat. The grants you can stack are a big part of what you can ultimately afford.
