How Much HDB BTO Flat Can You Afford Earning $5,000 a Month?

A young first-timer couple earning $5,000 a month combined is a common BTO applicant profile. With $30,000 in CPF OA and $15,000 in cash, the household can afford a BTO flat priced up to about $440,850 on a 25-year HDB loan.

The loan is what sets the budget. The Mortgage Servicing Ratio caps the instalment at 30.0% of income, which allows a monthly instalment of up to $1,500. At 2.6% over 25 years, that supports a loan of $330,637, which at 75.0% loan-to-value covers a flat of $440,850. The household's $130,000 of CPF, cash and grants is more than the $110,212 down payment needs, so saving more would not raise the budget; only a higher income would.

As first-timers on $5,000, the household qualifies for an Enhanced CPF Housing Grant of $85,000. The grant falls by $5,000 for each $500 of extra monthly income and stops above $9,000. HDB assesses income as the average over the 12 months before you apply, so a recent raise or bonus can move the household into a lower grant tier. Grants total $85,000.

At $440,850, the monthly instalment is about $1,500, 30.0% of income, right at the MSR cap. Most households pay this from CPF OA rather than cash, which keeps take-home pay intact but means those OA contributions go to the flat instead of building retirement savings.
