Property Financing · CPF · Singapore
CPF is the single most misunderstood factor in property equity cashout. Most Singapore property owners know roughly how much CPF they used — but almost none account for the accrued interest that compounds silently at 2.5% per year from the day they first withdrew. The result is a cashout figure that is often $50,000–$300,000 lower than expected. This guide explains exactly how it works and what to do about it.
When you use CPF Ordinary Account (OA) money to buy a property — whether for the down payment, monthly mortgage instalments, stamp duty, or legal fees — the CPF Board charges accrued interest at 2.5% per year on all CPF withdrawn, from the date of each withdrawal.
This accrued interest is not money you pay out of pocket. It is the interest your CPF OA would have earned had the money stayed in your account. When you use CPF OA money for your property, the CPF Board charges accrued interest — 2.5% per annum — on all CPF withdrawn, from the date of withdrawal until the date of refund on sale or full loan repayment.
For property equity cashout purposes, this matters because the total CPF deduction from your available cashout is not just the principal you withdrew — it includes every dollar of accrued interest that has accumulated since purchase.
Most Singapore property owners know they used, say, $180,000 in CPF. They subtract $180,000 from their cashout calculation and assume that is correct. It is not. On a property purchased 15 years ago, the accrued interest on $180,000 at 2.5% p.a. compounding is approximately $80,000–$90,000 — making the real deduction closer to $260,000–$270,000. This gap of $80,000–$90,000 is money that disappears from the available cashout that nobody warned them about.
When a bank calculates your maximum property equity cashout, CPF is deducted in full — principal plus all accrued interest to date — from the loan quantum available to you.
You can only cash out against equity you built up with your own cash. The portion of the property funded by CPF, and the accrued interest on it, is not available to be taken as cash. According to the CPF Board, CPF savings used for a property are tied to the property and must be returned to your CPF account when the property is sold, so the bank will not let you convert CPF-funded equity into a cash payout.
This means the bank effectively treats your CPF-funded equity as already spoken for — it cannot be unlocked as cash via an equity loan. Only the equity you built with non-CPF funds (your own cash, non-CPF mortgage repayments) is available for cashout.
Maximum cashout = (Property value × LTV%) − Outstanding mortgage − CPF principal used − CPF accrued interest
Most people calculate the first three terms correctly. The fourth term — CPF accrued interest — is almost always underestimated or missed entirely.
For TDSR-exempt cashout (no income check), the LTV cap is 50%:
Maximum TDSR-exempt cashout = (Property value × 50%) − Outstanding mortgage − CPF principal − CPF accrued interest
On a $200,000 CPF withdrawal at the 2.5% p.a. OA rate, the accrued interest reaches approximately $28,000 by Year 5, $62,000 by Year 10, and $219,000 by Year 30. By Year 30, the total CPF refund required is approximately $419,000 — more than double the original withdrawal.
| CPF withdrawn | Years held | Accrued interest | Total CPF deduction |
|---|---|---|---|
| $150,000 | 5 years | ~$20,000 | ~$170,000 |
| $150,000 | 10 years | ~$47,000 | ~$197,000 |
| $150,000 | 15 years | ~$81,000 | ~$231,000 |
| $200,000 | 10 years | ~$62,000 | ~$262,000 |
| $200,000 | 20 years | ~$131,000 | ~$331,000 |
| $300,000 | 15 years | ~$162,000 | ~$462,000 |
There is no cap on CPF accrued interest. It compounds indefinitely at 2.5% p.a. on the total outstanding CPF principal. The longer you have owned your property and the more CPF you used, the larger this deduction becomes. Owners of properties purchased in the 1990s or early 2000s — particularly retirees — may find their CPF deduction has doubled or tripled from the original withdrawal amount.
Never estimate your CPF figure. The exact number is available online in minutes and makes a significant difference to your cashout calculation.

Under the "My CPF" section, select "Property" or "Home Ownership."
Select the relevant property. You will see two key figures: "Total Principal Amount Withdrawn" and "Total Accrued Interest."
Principal + Accrued Interest = the total CPF deduction from your cashout calculation. This is the number your bank and your broker need.
Knowing your exact CPF total (principal + accrued interest) before any assessment conversation saves time and prevents false expectations. VeFi can run your full cashout calculation the moment you share this figure — along with your property value and outstanding mortgage.
CPF withdrawn over 10 years: $180,000 (down payment + monthly contributions). Accrued interest at 2.5% p.a. over 10 years: approximately $56,000. Total CPF deduction: $236,000.
If Mr Tan had only deducted the CPF principal ($180K) and ignored accrued interest ($56K), he would have estimated his cashout at $545K — a $56K overestimate. The TDSR-free band is narrow at $164K; if he needs more, income documentation is required.
Property fully paid — zero outstanding mortgage. CPF accrued interest at 2.5% p.a. over 20 years: approximately $131,000. Total CPF deduction: $351,000.
Mdm Lee estimated her cashout at around $580K (incorrectly using only the $220K principal). The correct figure is $449K — $131K lower due to accrued interest she was not accounting for. Still substantial for her needs, but the gap matters for planning purposes.
On a $200,000 CPF withdrawal at 2.5% p.a., the total CPF refund required by Year 30 is approximately $419,000 — more than double the original withdrawal.
Despite a large CPF deduction, Mr Wong still has $1.33M available TDSR-free. High-value properties absorb the CPF impact more easily. But if he had estimated based on the $200K principal alone, he would have calculated $1.55M available — a $219K overestimate on a fully paid property held 30 years.
A voluntary CPF refund at any time stops future accrued interest on the refunded amount. If you have excess cash and want to maximise your future equity cashout, making a voluntary CPF refund now reduces the accrued interest clock going forward. This is worth considering for property owners planning a cashout 2–5 years from now.
The single most important thing you can do before approaching any bank is to know your exact CPF figure — principal plus accrued interest. Without it, every cashout estimate is unreliable.
At VeFi, the first question we ask every new enquiry is: "What is your CPF principal plus accrued interest on the property?" If you do not know, we walk you through how to retrieve it from cpf.gov.sg — it takes five minutes — and then we run the full cashout calculation with the correct figures before any bank meeting is arranged.
This protects you from the most common disappointment in equity cashout: arriving at a bank meeting expecting $600,000 available and being told it is $420,000 because of CPF accrued interest nobody told you about.
