The Central Provident Fund (CPF) is Singapore's mandatory social security savings scheme. Every working Singaporean and Permanent Resident contributes a percentage of their monthly salary to CPF, split across three accounts: Ordinary Account (OA) for housing and education, Special Account (SA) for retirement, and MediSave Account (MA) for healthcare. For employees under 55, the total contribution is 37% of wages (20% employee + 17% employer), making it one of the highest mandatory savings rates in the world. CPF money earns guaranteed interest: 2.5% on OA and 4% on SA and MA, with an extra 1% on the first $60,000 of combined balances and an additional 1% on the first $20,000 for members aged 55 and above. This guide breaks down the exact numbers for 2026.
CPF Contribution Rates by Age (2026)
CPF contribution rates decrease as you age. The rates below apply to monthly wages above $750 (the contribution threshold). Wages above $6,800 per month ($81,600 per year) are subject to an additional wage ceiling.
| Age bracket | Employee | Employer | Total | OA | SA | MA |
|---|---|---|---|---|---|---|
| 55 and below | 20% | 17% | 37% | 23% | 6% | 8% |
| Above 55 to 60 | 15% | 15% | 30% | 15.5% | 4.5% | 10% |
| Above 60 to 65 | 9.5% | 11.5% | 21% | 7% | 3.5% | 10.5% |
| Above 65 to 70 | 7% | 9% | 16% | 3.5% | 2.5% | 10% |
| Above 70 | 5% | 7.5% | 12.5% | 1% | 1% | 10.5% |
CPF Interest Rates (Guaranteed)
CPF pays guaranteed interest on all balances, risk-free. These rates are reviewed quarterly but have remained stable for years. The extra interest on the first $60K is one of the best risk-free returns available anywhere in the world.
| Account | Base rate | Extra 1% (first $60K combined) | Extra 1% (55+ on first $30K) |
|---|---|---|---|
| Ordinary Account (OA) | 2.5% | Up to 3.5% | Up to 4.5% |
| Special Account (SA) | 4.0% | Up to 5.0% | Up to 6.0% |
| MediSave (MA) | 4.0% | Up to 5.0% | Up to 6.0% |
| Retirement Account (RA) | 4.0% | Up to 5.0% | Up to 6.0% |
CPF Balances: What to Expect by Age
Approximate CPF balances for a Singaporean earning the median wage ($5,000/month) who has contributed continuously since age 25, including employer contributions and compounding interest.
| Age | OA balance | SA balance | MA balance | Total CPF |
|---|---|---|---|---|
| 30 | ~$60,000 | ~$18,000 | ~$24,000 | ~$102,000 |
| 35 | ~$115,000 | ~$42,000 | ~$52,000 | ~$209,000 |
| 40 | ~$175,000 | ~$72,000 | ~$85,000 | ~$332,000 |
| 45 | ~$240,000 | ~$110,000 | ~$120,000 | ~$470,000 |
| 50 | ~$305,000 | ~$155,000 | ~$160,000 | ~$620,000 |
| 55 | ~$370,000 | ~$210,000 | ~$200,000 | ~$780,000 |
Using CPF OA for Housing
Most Singaporeans use their CPF OA to pay for HDB flats or private property. You can use OA funds for the down payment (up to 20% for HDB, 5-15% for private), monthly mortgage instalments, and stamp duty. The key trade-off: every dollar used from OA for housing must be repaid with accrued interest (2.5%) when you sell the property, before any cash proceeds go to you. This is the CPF refund mechanism. For an HDB flat bought at $500,000 with $100,000 from OA, after 20 years the accrued interest refund is about $64,000 — meaning you effectively paid $164,000 from your CPF, not $100,000. Many financial advisers recommend paying cash for the down payment and using CPF only for monthly instalments to minimize the accrued interest impact.
CPF Voluntary Contributions: Top-Up and Transfer
Two powerful moves to boost retirement savings: 1) SA Top-Up (under the Retirement Sum Topping-Up Scheme) — contribute cash to your own SA or a loved one's SA/RA, and receive income tax relief of up to $8,000 per year for self top-ups and $8,000 for top-ups to family members ($16,000 total). At a 15-20% marginal tax rate, this saves $1,200-$3,200 in tax while earning 4%+ guaranteed interest on the SA. This is widely considered one of the best tax moves available to working Singaporeans. 2) OA-to-SA Transfer — transfer money from your OA (earning 2.5%) to your SA (earning 4%), permanently increasing your returns. The catch: SA money is locked until 55 and cannot be used for housing. Only do this if you do not need the OA money for a property purchase.
Frequently Asked Questions
What is the CPF contribution rate in 2026?+
For employees aged 55 and below, the total CPF contribution rate is 37% of monthly wages — 20% from the employee and 17% from the employer. This applies to wages above the $750 monthly contribution threshold and up to the $6,800 monthly ordinary wage ceiling ($81,600 per year). Rates decrease for older workers: 30% total for ages 55-60, 21% for 60-65, 16% for 65-70, and 12.5% for above 70. The government periodically reviews these rates.
What interest does CPF pay?+
CPF pays guaranteed risk-free interest: 2.5% per year on the Ordinary Account (OA) and 4% per year on the Special Account (SA), MediSave Account (MA), and Retirement Account (RA). An extra 1% interest is paid on the first $60,000 of combined CPF balances (with up to $20,000 from OA). Members aged 55 and above earn an additional 1% on the first $30,000 of combined balances (with up to $20,000 from OA). This means SA balances can effectively earn up to 5% (or 6% for those 55+) risk-free — among the best guaranteed returns in the world.
How is CPF split between OA, SA, and MA?+
For members aged 55 and below, the 37% total contribution is split: 23% to OA, 6% to SA, and 8% to MA. The OA allocation is the largest because it can be used for housing and education. As you age, the MA allocation increases (to cover rising healthcare costs) while the OA and SA allocations decrease. After 55, the OA and SA are combined into the Retirement Account (RA) from which CPF LIFE payouts are made.
Can I use CPF to buy a house?+
Yes, CPF OA funds can be used for purchasing HDB flats or private property. For HDB, you can use OA for up to 20% down payment and full monthly mortgage. For private property, OA can be used for up to 5-15% of the purchase price (depending on loan-to-value ratio) and monthly mortgage. The key catch: when you sell the property, you must refund the amount used from CPF plus 2.5% accrued interest back to your OA before receiving any cash proceeds. This refund mechanism means using CPF for housing has a hidden cost that many buyers overlook.
What is the CPF Annual Limit?+
The CPF Annual Limit is $37,740 for 2026 — this is the maximum total CPF contributions (mandatory + voluntary) in a calendar year. The annual limit applies across all employers if you have multiple jobs. Mandatory contributions from your salary count toward this limit first. Any voluntary contributions (including top-ups under the Retirement Sum Topping-Up Scheme) are separate from this limit and have their own caps.
Should I top up my CPF SA?+
For most working Singaporeans, topping up your SA is one of the smartest financial moves available. You get immediate income tax relief of up to $8,000 per year (saving $1,200-$3,200 in tax at typical marginal rates), and the money earns 4%+ guaranteed interest risk-free. The trade-off: SA money is locked until age 55 and cannot be withdrawn for housing or other needs before then. If you have an adequate emergency fund, no high-interest debt, and do not need the cash for a near-term property purchase, SA top-up is almost always worth it.
When can I withdraw CPF money?+
At age 55, you can withdraw any CPF savings above the Full Retirement Sum (FRS) in your Retirement Account. The FRS for members turning 55 in 2026 is $205,800. If your combined OA and SA balances exceed the FRS, the excess can be withdrawn in cash. From age 65 (the CPF LIFE payout eligibility age), you receive monthly payouts for life under CPF LIFE. Early withdrawal is only allowed in specific circumstances: leaving Singapore permanently, severe illness, or death (to beneficiaries).
How much CPF do I need to retire in Singapore?+
The Full Retirement Sum (FRS) for 2026 is $205,800, which provides monthly CPF LIFE payouts of approximately $1,550-$1,750 per month from age 65. The Enhanced Retirement Sum (ERS) is $308,700, providing payouts of approximately $2,300-$2,650 per month. Most financial advisers suggest targeting the ERS if possible, supplemented by personal savings and investments, to maintain a comfortable standard of living in retirement. The actual amount you need depends heavily on whether you own your home outright, your healthcare needs, and your desired lifestyle.
