## How this works
Two things cap the price. Your income caps the loan: the monthly instalment can't exceed 30% of gross household income (the Mortgage Servicing Ratio), tested at HDB's 3% assessment rate for an HDB loan or MAS's 4% floor for a bank loan, over the shorter of 25 years or until age 65. Your savings cap the downpayment: both HDB and banks lend at most 75% of the price or valuation, so CPF, cash and grants must cover the other 25%.

The maximum price is the lower of the two: the loan your income supports plus your savings, or your savings divided by 25%. If you tick stamp duty, buyer's stamp duty (IRAS rates from 15 February 2023) is set aside from your savings first. Bank loans also need at least 5% of the price in cash, and other monthly debts count against the 55% TDSR.

HDB loans are for households earning up to S$16,000 a month (S$8,000 for singles) from 24 August 2026, at 2.6% interest. Grants are entered by you: use the CPF housing grant calculator to work them out. The result is an estimate; your HFE letter sets your actual loan amount.

## FAQs
### How much HDB flat can I afford on a S$7,000 salary?
Up to about S$590,450 with an HDB loan if your savings are large enough. At S$7,000 a month the 30% MSR allows a S$2,100 instalment, which supports a loan of about S$442,800 tested at 3% over 25 years. You would need about S$159,900 in CPF, cash and grants for the 25% downpayment and stamp duty.

### What is the downpayment for an HDB flat?
25% of the price or valuation, since both HDB and banks lend up to 75%. With an HDB loan the whole 25% can come from CPF Ordinary Account savings and grants. With a bank loan at least 5% of the price must be cash.

### What is the income ceiling for an HDB loan?
S$16,000 a month for families and S$8,000 for singles, for HFE letter applications from 24 August 2026 (raised from S$14,000 and S$7,000). Households above the ceiling can still buy a resale flat with a bank loan.

### Why does HDB use 3% when the loan rate is 2.6%?
HDB assesses how much you can borrow at a 3% interest rate floor, introduced on 30 September 2022, so that the loan stays affordable if rates rise. You still pay the concessionary 2.6% on the loan.
