CPF accrued interest is the interest your CPF savings would have earned if they had remained in CPF instead of being used for housing. When you plan a sale, it helps explain why the housing refund can be larger than the principal you withdrew.
The refund affects how much cash you receive from the sale. It should be accounted for separately from the property’s investment profit or loss, because the money returns to your CPF savings.
- The CPF principal used for housing.
- The accrued interest and total required refund.
- The separate cash balance after loan redemption, CPF refund and selling expenses.
What is included in a CPF housing refund?
The required refund generally includes CPF principal withdrawn for housing and accrued interest. Special circumstances, including property pledges, can change the amount. Check each owner’s official figure rather than estimating from the deposit alone.
CPF housing use may continue through monthly mortgage payments. A useful review therefore starts with your actual withdrawal record, not just what you remember paying when you bought the property.
For the refund rules, refer to CPF Board’s housing refund guidance.
How does accrued interest build up?
CPF Board explains that accrued interest runs from the use of CPF savings until the refund and uses prevailing CPF interest rates with annual compounding.
Each withdrawal has its own timing, so a series of monthly housing payments is different from one lump sum used at purchase.
See CPF Board’s explanation of why accrued interest is refunded. As at this review, the OA rate for October–December 2026 is 2.5% per annum; check CPF’s current interest rates for later periods.
A simplified illustration
Assume one $100,000 withdrawal, a constant 2.5% annual rate, five complete annual compounding periods and no additional withdrawals or refunds:
$100,000 × 1.025⁵ ≈ $113,141
Illustrative accrued interest: approximately $13,141.
This is a mathematical illustration, not a CPF quotation. The actual calculation depends on withdrawal and refund dates, applicable rates and subsequent transactions. Do not apply this single-lump-sum formula to your total CPF usage if that total accumulated over many years.
What changes when you sell?
Your sale needs to account for the mortgage, required CPF refund and transaction expenses. What remains as cash is a different figure from the amount returned to CPF.
Consider this hypothetical sale, assuming the full CPF refund is payable and no SSD applies:
- Selling price
- $700,000
- Less housing loan redemption
- $280,000
- Less assumed CPF refund
- $250,000 principal + $45,000 accrued interest = $295,000
- Less assumed selling costs
- $20,000
- Illustrative cash balance
- $105,000
The $295,000 CPF refund and $105,000 cash balance serve different planning purposes. The assumed accrued interest in this example is an input, not a calculation from a specified withdrawal history.
This also does not establish investment profit. To assess the ownership result, consider original acquisition costs, financing, upkeep and any rental income. Do not classify every amount that reduces the cash payout as an investment expense.
Where can you find your actual refund amount?
Log in to CPF’s Home ownership dashboard and use the “What Happens If” section to check the amount refundable on a sale. Review the figure for every owner who used CPF.
Record the date of your estimate and refresh it nearer the transaction. Continuing CPF deductions and the refund date can change the result. Ask your conveyancer to use updated figures in the completion account.
Keep the following records together:
- Each owner’s latest CPF refund information.
- A current loan redemption estimate.
- The expected selling price and a lower-price scenario.
- Agency, legal and other selling costs.
- The planned dates for sale completion and the next purchase.
What if the proceeds cannot cover the refund?
CPF Board states that a market-value sale with insufficient proceeds after the outstanding housing loan does not require a cash top-up of the CPF refund shortfall. This does not waive a mortgage gap or selling expenses; special cases need confirmation.
Our negative cash sale guide explains the distinction between low cash proceeds, a CPF shortfall and a separate cash funding requirement.
Can the refunded CPF fund your next home?
Reuse depends on CPF housing rules and your circumstances. For owners aged 55 and above, refunds may first replenish the Retirement Account up to the required retirement sum. Check the amount available before setting a purchase budget.
List the next home’s cash payments, permitted CPF payments and approved loan separately. Allow for when the funds become available, not just the total expected after selling.
Our property upgrade funding guide explains how to coordinate those sources with payment deadlines.
Should you use less CPF or make a voluntary refund?
Using more cash for housing preserves more CPF savings, but reduces the cash available for emergencies and other spending. Using CPF can preserve accessible cash, while creating a housing refund obligation. Compare both within your household budget and retirement plan.
A voluntary housing refund transfers cash back to CPF. It is not the same as paying down your mortgage, and it does not create extra household wealth. Check CPF’s current conditions and the effect on accessible reserves before proceeding.
Aim for a funding arrangement you can sustain. Reducing a future refund figure is only one consideration; it should not leave you short of money for present commitments.
