Every month, CPF takes a share of your pay and puts part of it in your Ordinary Account (OA). You can use that money for your home, but you must put it back when you sell, with interest. The “interest” is not a fee paid to anyone else. It is paid into your own OA. So the true cost of using CPF is simple: the money earns 2.5% a year in your OA, and your property has to beat that.

At a glance

  • If you are 55 or younger, you pay 20% of wages and your employer pays 17%, a total of 37%. An older version of this article said 20% from each side. That is out of date.
  • The OA pays 2.5% a year, with a legislated floor of 2.5%.
  • When you sell, you refund the CPF principal you used plus accrued interest. It goes back to your OA (or first to your Retirement Account if you are 55 or older), not to you as cash.
  • A S$200,000 withdrawal that stays out for 30 years grows to about S$419,500 that you must refund.
  • Using CPF for the monthly instalment is not “free”. Whether it is a good idea depends on what your cash could safely earn instead.

What CPF can pay for

Only your OA savings can be used for housing. Under the CPF Housing Scheme, you can use OA money for the downpayment, stamp duties, legal fees and the monthly mortgage instalment. If you buy with a bank loan, the bank still needs part of the downpayment in cash. For the rules on how much cash, see our LTV guide.

CPF caps what you can use. The Valuation Limit is the lower of the purchase price and the valuation. With a bank loan, the Withdrawal Limit is 120% of the Valuation Limit, once you have set aside the Basic Retirement Sum. The banks’ association gives an example: a flat priced at S$300,000 with a valuation of S$330,000 has a Valuation Limit of S$300,000 and a Withdrawal Limit of S$360,000 (ABS guide, Aug 2026). When you reach the limit, you pay all further instalments in cash.

There is also a lease rule. If the remaining lease can last the youngest buyer to age 95, the cap is the lower of price and valuation. If not, CPF reduces what you can use. Use the CPF Housing Usage Calculator for your own case.

The refund: what you really owe

When you sell or transfer the property, you must refund two things: the principal you took out (P) and the accrued interest (I). The interest is, in CPF’s words, the amount you would have earned if the savings had stayed in your OA, at the OA rate. CPF’s housing dashboard shows your exact figure.

Example (illustrative). Say you used S$200,000 of OA savings for the downpayment and stamp duty. You sell after 30 years. If the OA rate stays at 2.5% and the interest compounds each year, the accrued interest is about S$219,500. You refund about S$419,500 in total. This matches the figure in the earlier version of this article.

Two things make the refund less scary than it looks:

  • You never refund more than the sale gives you. If the sale price does not cover your outstanding loan plus the CPF refund, CPF says you refund only the price less the outstanding loan. You do not top up the shortfall in cash, as long as you sold at market value.
  • The interest lands in your own account. You pay it to yourself. That is why the idea that CPF use “costs 5%” (2.5% owed plus 2.5% lost) double-counts. The 2.5% you lose and the 2.5% you owe are the same 2.5%.

What you do lose is access. A dollar in your OA cannot buy a holiday. It can only fund your next home, or flow into your retirement savings at 55.

Worked example: is it worth using CPF?

Say a couple use S$200,000 of OA for a condo and sell after 10 years. Compare two paths (assuming the OA rate stays at 2.5%):

Leave S$200,000 in the OAUse it for the condo
After 10 yearsabout S$256,000 in the OAabout S$256,000 refunded to the OA
What else you getNothingThe property’s gains and rent on that S$200,000

The refund puts you back at the same OA balance. The difference is the property. If it earns more than about S$56,000 on that S$200,000 over ten years (2.5% a year, compounded), after all costs, you are ahead. If not, you would have done as well by leaving the money in the OA, with no risk and no stamp duty. Costs include stamp duties (see our cooling measures guide), maintenance, vacancy and agent fees.

The amount you owe back grows every year. The sale price may not. If you sell at a loss, CPF limits the refund to your net sale proceeds, but that still means your retirement money is smaller than it would have been.

Monthly instalments: CPF or cash?

Every dollar of OA you spend on instalments also accrues 2.5% a year. Say you pay S$1,500 a month from your OA for 10 years. That is S$180,000 of principal. At 2.5%, the accrued interest is about S$24,000 (CPF interest is calculated monthly and compounded yearly, so your own figure will differ slightly).

The choice between CPF and cash comes down to one test: can your spare cash earn more than 2.5% a year, safely?

  • If your cash can safely earn more than 2.5% elsewhere, paying instalments with CPF and keeping the cash invested wins on paper.
  • If your cash earns less (for example in an ordinary savings account), paying with cash and leaving the OA to grow can be better.

Look at the cost of the loan itself too. In October 2026, bank floating packages cost about 1.5–1.8% and fixed about 2.0–2.2%, and the HDB loan costs 2.6% (the OA rate plus 0.1 point). The OA pays more than a cheap bank loan costs. That means that paying down a low-rate bank loan early with cash is not an obvious win, because your OA earns more than you save in loan interest. Compare package rates in our mortgage guide and test your instalment in the mortgage calculator.

There are three other points:

  1. Voluntary refund. CPF lets you refund housing withdrawals early with cash. The earlier you refund, the less you refund on sale, and the more cash you get from the sale. The cash then earns the OA rate. It is a sensible place for money you cannot use better, but it is locked in.
  2. Extra interest. The government pays extra interest on the first S$60,000 of your combined balances, with at most S$20,000 from the OA. This extra interest goes to your SA or RA. Do not drain the OA to zero without thinking about it.
  3. The 4% accounts. The SA, MA and RA pay 4%, a floor guaranteed to 31 December 2027. Money used for housing cannot earn that.

Insurance and the HDB buyer

If you use CPF for the instalment on an HDB flat, you must have Home Protection Scheme cover. The premium comes from your OA, so it is one more drain on the account. Our guide to mortgage loan insurance explains how HPS compares with the private alternative.

When CPF use is a poor fit

  • You are close to 55. OA money that moves into your RA can no longer pay for a home. Our guide to buying before 55 covers the reserve option and the real costs.
  • You plan to hold for a short time. Seller’s Stamp Duty and the refund can wipe out a small gain.
  • You are stretching. A property that only works if you use every dollar of CPF has no safety margin. Our 3/3/5 affordability guide shows a way to test this.

Bottom line

CPF is your money, but it is money with a purpose. Using it for a home turns it into a 2.5% loan to yourself, and the property has to beat 2.5% to justify the move. The refund goes back to your OA, so the main cost is access, not interest. Know your withdrawal limit, check the refund figure before you sell, and compare it with what your cash can safely earn. Then decide how much of your CPF to commit.
