CPF Interest Rates Explained
CPF interest rates are set by the government and reviewed quarterly based on a formula tied to bank interest rates, with legislated minimum floors.
Ordinary Account (OA) — 2.5% p.a.
The OA earns a guaranteed minimum of 2.5% p.a. This rate has not changed since July 1999. The OA is primarily used for housing, education, and CPFIS investments, so the lower rate reflects its more transactional nature.
Special Account (SA) & Medisave Account (MA) — 4.0% p.a.
Both SA and MA earn a guaranteed minimum of 4.0% p.a. The SA is designated for retirement and old-age needs, while MA covers healthcare expenses and MediShield Life premiums. The higher rate encourages members to build these critical long-term reserves.
Extra 1% Interest
All CPF members earn an extra 1% p.a. on the first S$60,000 of their combined CPF balances. The OA contribution to this S$60,000 pool is capped at S$20,000. This means:
- Up to S$20,000 in your OA can earn 3.5% p.a.
- Up to S$40,000 in your SA/MA can earn 5.0% p.a.
Members aged 55 and above receive an additional 1% on the first S$30,000 of combined balances (on top of the existing extra 1%). Source: CPF Board — Interest rates
Bank Savings Accounts in Singapore
Singapore banks offer a range of savings accounts with varying interest rate structures. Most accounts have a low base rate (often 0.05%–0.2% p.a.) and offer bonus interest when you meet certain conditions.
Common bonus interest conditions
- Crediting your salary into the account
- Spending on the bank's credit cards
- Purchasing insurance or investment products through the bank
- Paying bills via GIRO
- Maintaining a minimum monthly balance
Bonus rates can push effective returns to 1.5%–4% or higher, depending on the bank and how many conditions you meet. However, failing to meet conditions typically drops you back to the base rate.
Note: Bank savings account rates change frequently. The ranges above are typical as of 2026 but may not reflect current offers. Always check directly with the bank for the latest rates. Source: Monetary Authority of Singapore (MAS)
When CPF Wins
- Passive growth: CPF interest compounds automatically with zero effort. No conditions, no minimum deposits, no salary crediting required.
- SA/MA at 4%: Very few savings products in Singapore offer a guaranteed 4% return. Fixed deposits may approach this for short promotional periods, but the guaranteed nature of CPF SA/MA is hard to beat.
- Extra 1%: The additional 1% on the first S$60,000 further boosts effective returns for smaller balances.
When a Bank Account Wins
- Liquidity: You can withdraw your money anytime, for any reason. CPF funds are locked in for specific purposes.
- Emergency fund: Financial advisers generally recommend keeping 3–6 months of expenses in a liquid savings account for emergencies.
- Bonus rates: If you can consistently meet bonus conditions, some accounts may offer comparable or even higher rates than CPF OA.
5-Year Growth Example: S$20,000
Here's how S$20,000 would grow over 5 years in different scenarios. CPF interest compounds annually at the stated rate.
| Scenario | Year 1 | Year 3 | Year 5 | Total Interest |
|---|---|---|---|---|
| CPF OA (2.5%) | S$20,500 | S$21,538 | S$22,628 | S$2,628 |
| CPF OA + extra 1% (3.5%) | S$20,700 | S$22,175 | S$23,754 | S$3,754 |
| Bank savings (0.05% base) | S$20,010 | S$20,030 | S$20,050 | S$50 |
| Bank savings (1.5% with conditions) | S$20,300 | S$20,914 | S$21,538 | S$1,538 |
Note: Bank rates shown are illustrative. Actual savings account interest is typically calculated daily and credited monthly, which may result in slightly different totals due to compounding frequency. CPF interest is calculated monthly and credited annually.
The Bottom Line
For pure interest returns, CPF SA/MA at 4% is hard to beat with any risk-free savings product in Singapore. CPF OA at 2.5% is also competitive, especially when you factor in the extra 1% on the first S$20,000. The main trade-off is liquidity — your CPF money is locked in for specific purposes, while a bank savings account gives you instant access. A balanced approach is often best: let your CPF grow for retirement, and maintain a liquid emergency fund in a bank account.

Frequently Asked Questions
Is CPF OA interest really guaranteed?
Yes. The CPF Ordinary Account earns a legislated minimum of 2.5% p.a. This rate has been in place since 1999 and is guaranteed by the Singapore government. Bank savings account rates, by contrast, can change at any time at the bank's discretion.
Can bank savings accounts beat CPF SA's 4%?
Some banks offer promotional or bonus interest rates that can reach 4% or higher, but these typically come with strict conditions — such as minimum spending on credit cards, salary crediting, insurance purchases, or investment products. The base rate for most Singapore savings accounts is well below 1%. CPF SA's 4% is guaranteed with no conditions attached.
Should I keep money in CPF OA or move it to a bank savings account?
It depends on your needs. CPF OA offers a guaranteed 2.5% p.a. with zero effort, but your money is locked in for housing, education, or retirement. A bank savings account gives you full liquidity — you can withdraw anytime — but returns are typically lower unless you meet bonus conditions. Many financial advisers suggest keeping an emergency fund in a bank account and letting CPF balances grow.
What is the extra 1% interest on CPF?
CPF members earn an extra 1% p.a. on the first S$60,000 of their combined CPF balances (OA contribution to this pool is capped at S$20,000). This means up to S$20,000 in your OA can earn 3.5%, and up to S$40,000 in your SA/MA can earn 5%. Members aged 55 and above receive an additional 1% on the first S$30,000.
Are CPF interest rates higher than fixed deposit rates in Singapore?
CPF SA/MA at 4% p.a. is generally competitive with or higher than most Singapore fixed deposit rates, which typically range from about 2% to 3.5% p.a. depending on tenure and amount. CPF OA at 2.5% is comparable to some longer-tenure fixed deposits. However, fixed deposits lock your money for a set period (e.g. 6–12 months), while CPF funds are locked until age 55 or for specific purposes.
