CPF Accrued Interest
What CPF accrued interest is, how it impacts your property sale and retirement savings, and strategies to manage it in 2026.
CPF accrued interest is the interest that your CPF Ordinary Account (OA) savings would have earned if they had not been withdrawn to pay for your property. When you sell your home, you must refund the CPF principal used plus all accrued interest back to your OA before receiving any cash proceeds. At the OA rate of 2.5% per annum, accrued interest can add tens of thousands of dollars over a typical mortgage tenure.

What Is CPF Accrued Interest?
CPF accrued interest is the amount of interest that your CPF OA savings would have accumulated if they had remained in your account instead of being used to purchase or pay for a property. The CPF Board computes this at the prevailing OA interest rate of 2.5% per annum, compounded annually, from the date each CPF withdrawal was made until the date of refund (typically when you sell the property).
The purpose of the accrued interest rule is to ensure that your CPF retirement savings are not permanently depleted by housing use. Since CPF OA funds are meant for both housing and retirement, the government requires that any OA money used for property must be returned with interest upon sale — effectively restoring your CPF balance to what it would have been. This is why the refund amount upon selling your property is always CPF principal used + accrued interest, not just the principal.
It is important to understand that accrued interest is not an additional charge or penalty. You are not paying 2.5% to anyone — you are restoring the interest your CPF account would have earned. The money goes back into your own OA, boosting your retirement savings. However, it does reduce the cash proceeds you receive from a property sale, which catches many homeowners off guard.
How It Works
Every time you make a CPF OA withdrawal for your property — whether for the down payment, stamp duty, legal fees, or monthly mortgage instalments — the CPF Board records the date and amount. Interest at 2.5% p.a. starts accruing on each withdrawal from the date it leaves your OA. The interest compounds annually, and the cumulative accrued interest is updated in your CPF statement (visible under My Property > Property Dashboard on my.cpf.gov.sg).
When you sell the property, the refund order is: (1) outstanding housing loan repaid, (2) CPF principal + accrued interest refunded to your OA, (3) any remaining cash proceeds go to you. If the sale price is insufficient to cover both the loan and the CPF refund, you only refund what the sale proceeds allow — you do not need to top up the shortfall from other funds. However, the unrefunded amount still counts towards your housing obligation if you buy another property using CPF.
You can check your current CPF accrued interest anytime on my.cpf.gov.sg under the property section. The CPF Board also provides a calculator that estimates your accrued interest based on the total OA funds used and the duration of use. A simple estimate: for every S$100,000 used from OA over 20 years at 2.5% compounding, the accrued interest is approximately S$63,860 — meaning you would need to refund ~S$163,860 to your OA from the sale proceeds.
CPF Accrued Interest in Singapore
The accrued interest rule applies to all residential property purchases in Singapore that use CPF OA funds — including HDB flats, Executive Condominiums (ECs), and private condominiums. It applies regardless of whether you are a first-time buyer or upgrading. The only scenario where accrued interest does not apply is when you sell your property after reaching 55 and have already met your Full Retirement Sum (FRS) — in this case, excess OA above the FRS is yours to keep without the accrued interest obligation.
In Singapore’s property-centric culture, where home ownership exceeds 90%, CPF accrued interest affects the vast majority of households. For HDB owners who bought their BTO flat at subsidised prices and sell after the Minimum Occupation Period (MOP), the accrued interest refund can still leave substantial cash proceeds. But for private property buyers who used large CPF sums for the purchase and took 25–30 year mortgages, the accrued interest can grow to S$80,000–S$150,000+, significantly reducing the cash available upon sale.
This has implications for the popular Singapore strategy of “right-sizing” — selling a larger property in retirement to downsize and pocket the cash difference. If a large portion of the sale proceeds must return to CPF as accrued interest, the net cash proceeds may be much less than expected. This is why financial planners recommend checking your CPF property dashboard early and factoring accrued interest into any property upgrade or downgrade decision.
Real-World Examples
Consider a couple who bought a 4-room HDB BTO flat in 2005 for S$280,000. They used S$56,000 from CPF OA for the down payment and have been paying their mortgage of S$1,200/month from CPF OA for 20 years (total monthly CPF used: S$288,000). Their total CPF principal used is S$344,000. The accrued interest on these withdrawals over 20 years at 2.5% compounding is approximately S$130,000. When they sell their flat in 2025 for S$550,000, the refund to CPF OA is S$344,000 + S$130,000 = S$474,000. After clearing any remaining loan, the cash proceeds to them are only about S$76,000 — despite a seemingly large sale price.
Now consider a single professional who bought a condo in 2015 for S$1.2 million, using S$200,000 from CPF OA for the down payment and S$2,000/month for mortgage over 10 years (S$240,000). Total CPF used: S$440,000. Accrued interest over 10 years: approximately S$62,000. Refund required: S$502,000. If the condo is sold for S$1.3 million with S$600,000 loan remaining, the distribution is: S$600,000 to bank, S$502,000 to CPF OA, leaving S$198,000 in cash.
In both cases, the accrued interest is a significant sum that returns to CPF — strengthening retirement savings but reducing spendable cash. This trade-off is central to Singapore’s housing-retirement planning nexus and should be modelled using the TKN Retirement Calculator.
Why It Matters for Investors
CPF accrued interest directly affects your retirement readiness and property upgrade decisions. For investors focused on building passive income, understanding accrued interest helps you decide whether to use CPF OA for housing or preserve it for CPFIS investments or the higher-interest SA. Every dollar of OA used for housing is a dollar not compounding at 2.5% in your CPF — which the accrued interest rule is designed to offset.
One practical strategy: if your housing loan interest rate is below 2.5% (as is currently the case with SORA at ~1.0–1.1%), some financial planners suggest paying your mortgage from cash and leaving OA funds to compound. This reduces your accrued interest obligation and keeps more CPF earning interest. However, this only makes sense if you have sufficient cash flow and an emergency fund.
When planning property transactions, always check your CPF property dashboard for the current accrued interest figure. Factor it into your expected net cash proceeds from a sale. For retirement planning, remember that the refunded amount (principal + accrued interest) goes back into your OA and can be used for your RA at 55, contributing to your Full Retirement Sum and CPF LIFE payouts.
Frequently Asked Questions
How is CPF accrued interest calculated?
CPF accrued interest is calculated at 2.5% per annum (the OA interest rate), compounded annually, on each CPF OA withdrawal used for your property. It accrues from the date of each withdrawal until the date you refund the amount (typically upon property sale). Check your exact figure on my.cpf.gov.sg.
Do I have to pay back CPF accrued interest when I sell my home?
Yes, when you sell your property, you must refund the total CPF principal used plus all accrued interest to your OA from the sale proceeds. If the sale proceeds are insufficient, you refund what is available — you do not need to top up from other funds.
Can I avoid CPF accrued interest?
You can minimise accrued interest by using less CPF OA for your property — for example, paying your mortgage from cash instead of CPF. You cannot eliminate accrued interest entirely if you have already used CPF OA funds for housing, but paying from cash going forward stops new accrued interest from accumulating.
Does CPF accrued interest apply to HDB and private property?
Yes, it applies to all residential properties purchased using CPF OA funds — HDB flats, ECs, and private condominiums. The calculation method is the same regardless of property type. The only exception is if you have met your FRS at age 55, in which case excess OA can be withdrawn without the accrued interest obligation.
Where can I check my CPF accrued interest?
Log in to my.cpf.gov.sg with Singpass and navigate to My Property > Property Dashboard. You will see the total CPF principal used, accrued interest, and the total refund amount required. The CPF Board also sends annual statements showing this information.
