Base Interest Rates by Account
The CPF Board guarantees minimum (floor) interest rates on your savings. These have remained unchanged for many years.
| Account | Base Interest Rate | Floor Rate Since |
|---|---|---|
| Ordinary Account (OA) | 2.5% p.a. | 1999 |
| Special Account (SA) | 4.0% p.a. | 2001 |
| Medisave Account (MA) | 4.0% p.a. | 2001 |
| Retirement Account (RA) | 4.0% p.a. | 2001 |
Extra 1% Interest on First S$60,000
All CPF members earn an additional 1% per year on the first S$60,000 of their combined CPF balances. Of this S$60,000 cap, up to S$20,000 can come from the Ordinary Account.
This means the effective interest rates on your first S$60,000 are:
| Account | Base Rate | + Extra 1% | Effective Rate |
|---|---|---|---|
| OA (first S$20,000) | 2.5% | +1.0% | 3.5% |
| SA / MA / RA (up to S$40,000) | 4.0% | +1.0% | 5.0% |
For members aged 55 and above, an additional extra 1% is paid on the first S$30,000 of combined balances, making the effective rate up to 6% on SA/RA for that portion.
How CPF Interest Compounds
CPF interest is computed monthly and credited annually on 31 December. Here's how it works:
- Monthly calculation: Your account balance at the end of each month earns 1/12th of the annual rate.
- Compound effect: The interest earned each month is added to your balance for the next month's calculation.
- Annual crediting: The total accumulated interest for the year is credited to your account on 31 December.
✦ Example: S$100,000 in SA at 4% p.a.
Monthly interest = S$100,000 × (4% ÷ 12) = S$333.33
After 1 year (with monthly compounding): S$104,074
That's S$74 more than simple interest, thanks to monthly compounding.
Why Does SA Earn More Than OA?
The Special Account and Medisave Account earn 4% because these funds are meant for long-term retirement and healthcare needs. The government has committed to these higher floor rates to help your retirement savings grow meaningfully over time. The OA at 2.5% is designed for more frequent withdrawals (housing, education) and earns a lower rate accordingly.
