CPF Accrued Interest on Property: How It Works and What You Owe

CPF Accrued Interest on Property: How It Works and What You Owe

CPF accrued interest is the interest your Ordinary Account (OA) savings would have earned had you not used them for your property. When you sell, you refund the principal you withdrew plus that interest, and the money goes back into your own CPF accounts, not to the government. At the current OA rate of 2.5% a year, compounded annually, the interest adds up to a sizeable sum over a long holding period. It is worth planning for before you buy.

TL;DR

  • Accrued interest is not a fee or a penalty. It restores what your OA would have earned, and it is refunded to your CPF, not paid to anyone else.
  • The OA rate is 2.5% a year for 1 October to 31 December 2026, and the interest compounds annually.
  • It keeps building after your housing loan is fully paid. It stops only when you refund.
  • A voluntary housing refund shrinks the balance on which interest builds, but it locks cash back into CPF, so only do it with money you will not need.
  • If you are 55 or older, the refund first tops up your Retirement Account towards the Full Retirement Sum.

What CPF accrued interest actually is

When you use OA savings for a home, that money leaves your account and stops earning CPF interest. CPF Board explains that CPF savings are designed mainly for retirement, so the refund on sale has two parts: the principal you withdrew and the interest those savings would have earned.

Principal and accrued interest returning to CPF

Think of it as a running tab in your own favour. Your OA is not shortchanged by your decision to buy. The tab simply gets settled when the property is sold or transferred.

This is why the common claim that accrued interest is a cost deserves care. Cash leaves your pocket on the day of sale, but it lands in your CPF. What you lose is liquidity, not wealth. Whether that matters depends on your age, your other savings and how you value cash today against CPF balances you can only use for housing, healthcare and retirement.

How the interest is calculated

The rate is the prevailing OA rate, which has a floor of 2.5%. CPF Board's interest page sets out how the rates work. The interest compounds annually and runs from the date your CPF savings are used for the property until the refund is made.

Two details trip people up:

  1. It does not stop when the loan ends. Paying off your mortgage does not stop accrued interest. It keeps building until you refund the CPF, usually on sale.
  2. Each withdrawal has its own start date. The downpayment, each monthly instalment and any lump sum each begin accruing from their own date.

For your actual figure, do not rely on a rule of thumb. CPF Board lets you check the amount in the "What Happens If" section of your Home ownership dashboard, which shows what you would refund if you sold now.

A worked example

The numbers below are our own simplified illustration, not a quote. We assume S$200,000 of OA savings is used in one lump sum at 2.5% compounded annually, and that the rate stays flat. In practice your withdrawals are spread over time and the rate can change.

Years heldAccrued interestTotal refund to CPF
5S$26,282S$226,282
10S$56,017S$256,017
20S$127,724S$327,724

After ten years the interest is about 28% of the principal. After twenty it is about 64%. Compounding does the work, which is why the final years of ownership cost more than the first.

Now take a sale. Suppose your property sells for S$2,000,000, your outstanding loan is S$900,000, and you refund S$256,017 to CPF. The sale price minus those two items leaves about S$844,000 in cash, before agent fees, legal costs and any other deductions. That is why you should work backwards from the refund figure when you estimate your take-home proceeds.

How much CPF you can use in the first place

The accrued interest only exists on what you withdraw, so the withdrawal limit matters. According to CPF Board's guidance on how much CPF savings you can use for a home purchase, usage is generally capped at the lower of purchase price and valuation. With a bank loan, usage can extend to 120% of the valuation limit, provided you have set aside your Basic Retirement Sum.

A higher CPF draw means a smaller cash outlay today, and a larger refund on sale. Many buyers choose the mix without ever modelling the exit. We suggest you do the sum for a five, ten and twenty year hold before you decide.

Selling before and after age 55

The refund rules change at 55. CPF Board notes that if you are 55 or older, refunds go first to your Retirement Account until it meets the Full Retirement Sum. Only the balance after that is credited back to your OA, and any excess over what you need may be withdrawn in cash, subject to the rules.

This matters if you are a retiree thinking of right-sizing into a city apartment. The sale may not release as much spendable cash as the headline equity suggests, because part of it is channelled into retirement savings by design. CPF Board has a page comparing selling your home before and after age 55. Read it with your own numbers in hand.

If the owner dies, different rules apply. CPF Board states that the savings used for the property need not be refunded to the deceased member's account in the way they would on a sale, and the property forms part of the estate. Speak to CPF Board or a lawyer about an estate in your own situation.

Should you make a voluntary housing refund?

You can refund CPF savings to your OA while you still own the home, in any amount up to the total principal you have withdrawn. That reduces the balance on which interest accrues, so the refund due on sale is smaller. CPF Board sets out the case in three reasons.

In effect, the cash you put back earns the OA rate, and the accrued interest on that portion stops building. It is a safe, modest return, not a high one. Weigh these points:

  • Liquidity. Cash moved into CPF is not available for emergencies, school fees or a renovation.
  • Alternatives. If you have debt costing more than 2.5%, paying that down first usually makes more sense.
  • Your loan. If you are still servicing a mortgage, ask whether the cash is better kept as a buffer against rate moves. Our note on fixed versus floating loans covers that trade-off.
  • Your age. Closer to 55, more of the refund will be directed to your Retirement Account anyway.

This is a personal finance decision. If the sums are large, ask a licensed financial adviser, or contact CPF Board to confirm the figures before you transfer.

What it means for investors

Accrued interest affects investors in a way owner-occupiers feel less. If you use CPF for an investment unit, your exit proceeds are reduced by the refund, so your true return depends on that figure. A yield number alone hides it.

Start with the yield. A simple rental yield formula divides annual rent by the purchase price, and you can then adjust for costs. Next, subtract the accrued interest you expect on any CPF used, and compare the result with what that CPF would have earned if left in your OA. The refund returns to your CPF, so you are not losing it, but you cannot spend it freely.

Also remember the tax side. Rent is taxable, and our guide to property tax and rental income in Singapore walks through how. Stamp duties at purchase also change your break-even, so check buyer's stamp duty and ABSD rates before you commit.

Tenure also matters for how CPF can be used. Our piece on 99 versus 999 leasehold explains where the surprises tend to arise.

Non-citizens should check eligibility first. Permanent residents can read our summary of PR property rules. Foreign buyers cannot rely on this CPF route as a plan, so see our foreigner condo guide.

Our perspective on CPF and a condo purchase

We talk to buyers of all kinds: young professionals, families upgrading, investors and people nearing retirement. The question about accrued interest comes up from nearly all of them, usually late, once they have fallen for a floor plan.

Our view is simple. Decide your CPF usage the way you would decide a mortgage: with the exit in mind. Ask three things before you sign.

  1. How long do I realistically plan to hold this home?
  2. What will my refund be at that point, at 2.5% compounded?
  3. Will I still have enough in CPF and in cash if my plans change?

A buyer who answers these before the showflat visit chooses calmly. A buyer who learns the numbers at the point of sale often feels cheated, when the real problem was that nobody ran the numbers earlier.

We would also say that location and building quality shape how long you want to stay. A home that suits your life, near an MRT station and the city, is one you are likelier to hold through the compounding years. That is a better test than chasing the lowest upfront cash.

A short checklist before you decide

  • Log in to your CPF Home ownership dashboard and run the "What Happens If" check.
  • Model a five, ten and twenty year hold with the refund added.
  • Keep an emergency cash fund before any voluntary refund.
  • If you are within a few years of 55, plan how the Full Retirement Sum affects your sale.
  • Check the CPF Board interest rates page each quarter, as the OA rate is reviewed regularly and has a 2.5% floor.

FAQ

Is CPF accrued interest a real cost?

It is a real cash outflow when you sell, but it is paid into your own CPF accounts. CPF Board describes it as a way to keep your retirement savings whole, not as a penalty. The cost is in lost liquidity.

Does accrued interest stop once I finish paying my loan?

No. It keeps building until you refund the CPF, usually when you sell. Many owners assume it stops at the final instalment, so plan for it.

How do I find my exact refund figure?

Use the "What Happens If" section of your CPF Home ownership dashboard. It shows the principal and accrued interest as if you sold today. Your sales proceeds and loan balance then decide your final cash.

Can I refund part of my CPF early?

Yes. CPF Board allows a voluntary housing refund of any amount up to the total principal you withdrew. Keep enough cash for emergencies first, since the money returns to your OA.
