the OA covers it
Over the loan your CPF pays $578,147 and you pay $34,307 in cash. The OA covers every instalment until year 22, when you are 53; after that you top up in cash because less of your CPF goes to the OA as you get older.
The CPF you use earns accrued interest at the OA rate of 2.5%: about $232,360 by the end of the loan. If you sell, $810,507 goes back into your own CPF before you get any cash.

Singapore Citizens and PRs from the third year, CPF rates from 1 Jan 2026, on wages up to the S$8,000 ceiling. Rates above 55 to 65 rise on 1 Jan 2027 and the extra goes to the Retirement Account, so the OA still gets about 12% and 3.5% of wage. Each year of the loan uses that year's rates.
You earn S$5,000 at 32 and your co-owner earns S$4,500 at 31. A S$450,000 HDB loan at 2.6% over 25 years costs S$2,041 a month. Your OA gets S$1,150 a month and your co-owner's S$1,035, S$2,185 together, so CPF pays it all and the S$20,000 left in your OAs keeps growing.
From 50 the OA share falls to 15% of wage, then 12% from 55. On flat salaries the OAs run dry in year 22 and you top up about S$576 a month, rising to about S$901 by the last year. Over 25 years CPF pays about S$578,000 and you pay about S$34,000 in cash.

Yes. CPF's housing scheme lets your Ordinary Account pay the monthly instalments of an HDB loan, or a bank loan on an HDB flat or private property. How long it can keep paying depends on the flat and the loan.
Worked out from CPF's 2026 rate and allocation tables: 23% of your wage at 35 and below, 21% above 35 to 45, 19% above 45 to 50, 15% above 50 to 55, 12% above 55 to 60, 3.5% above 60 to 65 and 1% after that, on wages up to S$8,000 a month.
CPF pays what your OA holds and you pay the rest in cash. OA savings built up in earlier months are used first, so a balance can carry you for a while.
Less of your CPF goes to the OA as you age, from 23% of wage at 35 and below to 15% above 50 and 12% above 55, while the instalment stays the same.
It depends on the loan. On a new HDB flat with an HDB loan, your OA can pay the loan in full. On a resale flat with an HDB loan, CPF pays up to your housing limit, the lower of the price and the valuation when you bought, and then keeps paying if you set aside the Basic Retirement Sum. On a bank loan, the same applies but only up to another 20% of that limit; after that you pay in cash.
The interest your CPF would have earned had it stayed in your account, at the OA rate of 2.5% now. When you sell or transfer the home, you refund the CPF used plus this interest to your own CPF account.
0.1% above the CPF Ordinary Account rate, so 2.6% a year while the OA earns 2.5%. Bank loan rates are set by each bank.
Yes, if CPF pays the instalments on an HDB flat. HDB says the Home Protection Scheme is compulsory in that case.
