CPF Accrued Interest When You Buy and Sell Property

CPF accrued interest is the interest your Ordinary Account (OA) savings would have earned had you left them in CPF instead of putting them into a property. It follows the OA rate, which carries a legislated floor of 2.5% a year and has sat at that floor through 2026.

The refund goes back into your own CPF accounts when you sell, not to a bank or to the government. It still changes your decisions, because it decides how much of a sale lands as cash in hand.

Accrued interest compounds on every dollar you withdraw

CPF tracks each housing withdrawal from its date and applies the OA rate to it annually. The longer the property is held, the larger the gap between the principal withdrawn and the total repayable.

For $200,000 of OA savings used at purchase, with the OA rate assumed to stay at 2.5% throughout:

Years held	Principal withdrawn	Accrued interest	Total repayable
10	$200,000	about $56,000	about $256,000
20	$200,000	about $128,000	about $328,000
25	$200,000	about $171,000	about $371,000
30	$200,000	about $220,000	about $420,000

These are compound-interest illustrations on one withdrawal made at a single point in time. A real case has several withdrawals on different dates: the downpayment, the monthly instalments and any lump-sum repayments. CPF computes each from its own date.

Monthly instalments paid from OA add to the principal every month, so the tracked amount grows across the whole holding period rather than being fixed at purchase.

Two limits cap how much OA you can use

The Valuation Limit (VL) is the lower of the purchase price and the valuation at the time of purchase. The Withdrawal Limit (WL) is 120% of that figure.

Property and loan	OA usage ceiling
HDB flat with an HDB housing loan	Full purchase price, including the loan taken
HDB flat with a bank loan	VL, then up to the WL if the Basic Retirement Sum is set aside
Private property with a bank loan	VL, then up to the WL if the Basic Retirement Sum is set aside

Once you reach the VL, you can continue servicing the loan from OA only after setting aside the Basic Retirement Sum (BRS). Members below 55 set it aside across the Special and Ordinary Accounts combined; members aged 55 and above set it aside in the Retirement Account.

Reaching the WL means OA can no longer service the mortgage at all. From that point the instalment comes from cash, which is the constraint to model before committing to a long tenure funded largely from CPF.

A flat whose remaining lease cannot cover the youngest buyer using CPF to age 95 gets a prorated limit, so older leasehold property allows less OA use. Our CPF property guide covers the usage rules at purchase.

What you refund when you sell

On a sale or transfer, the proceeds first discharge the outstanding housing loan. The CPF refund of principal plus accrued interest comes next. Where you are aged 55 or above and have pledged your property for part of your retirement sum, that pledged amount is also refundable.

Where the refund lands depends on your age:

Age at sale	Where the refund goes
Below 55	Ordinary Account, available for the next property or a transfer to retirement savings
55 and above	Retirement Account first, up to your required retirement sum; the balance stays in the Ordinary Account

A seller aged 55 and above who expects the proceeds as spendable cash should model this before committing to a purchase that depends on it. The refund can be routed into the Retirement Account rather than released.

One narrow exception applies. A member who turned 55 before 1 January 2013 and had already set aside the Full Retirement Sum by that date refunds only the principal and accrued interest from 1 January 2013 onward.

Selling at market value caps the refund

A long-held property with heavy CPF use can reach the point where the loan plus the CPF refund exceeds the sale price. CPF handles this without a cash call.

Where the property is sold at market value and the proceeds cannot cover both the outstanding housing loan and the required refund, you refund the selling price less the outstanding loan. The shortfall is not topped up in cash.

The condition is the market-value sale. A below-market transfer, including one to a family member, does not attract the same treatment. Get a valuation before agreeing any transfer price within a family.

For sellers modelling the full cash position, our HDB selling costs guide and condo selling costs guide set out the other deductions that come before net proceeds.

A voluntary refund reduces what compounds

You can refund CPF savings used for housing before selling. The refund is capped at the full principal you withdrew, together with its accrued interest.

The trade-off runs in both directions. Cash used for a voluntary refund earns the OA rate inside CPF and stops that portion of the accrued interest from compounding further, which raises the cash you receive on a future sale. That same cash is then locked into CPF withdrawal rules rather than available to you.

A voluntary refund suits an owner who has cash sitting idle, expects to sell within a few years and wants more of the proceeds in hand. It suits an owner with thin cash reserves poorly, because the money cannot be retrieved for an emergency.

Upgraders feel it twice

A household selling a flat to buy private property meets the refund at the worst moment. The CPF refund leaves the sale proceeds and re-enters the OA, where it can fund the next purchase, but it does not arrive as cash for the Buyer's Stamp Duty, the option fee or the renovation.

Where the next purchase needs a 5% cash downpayment, that cash has to come from savings rather than from the refunded CPF. A seller who assumed the whole sale price would be available can find the cash portion short at completion.

Sellers aged 55 and above face the tighter version, because part of the refund is routed to the Retirement Account before anything remains in the OA. Our HDB to condo upgrade guide works through the sequencing, and the condo downpayment guide sets out which portions must be cash.

Checks before you use more OA

• Ask CPF for your current principal withdrawn and accrued interest for the property, and re-check it before you list.
• Confirm whether your planned OA use will cross the Valuation Limit, and whether you have set aside the Basic Retirement Sum.
• If you are 55 or above, work out how much of the expected proceeds will be routed to your Retirement Account rather than released as cash.
• Where the next purchase depends on cash from this sale, model the deal on proceeds after the CPF refund rather than on the sale price.

Using more OA reduces the cash you need at purchase and increases what returns to CPF at sale. That is the correct trade for a household that would otherwise be cash-short at completion. It is the wrong trade for a household relying on sale proceeds as cash within a few years.
