Singapore CPF OA vs SA vs MA Interest Rate Comparison 2026

Last updated: September 2026 | SeaMoneyTips

Summary

Your Central Provident Fund (CPF) money sits in three accounts, and each earns a different interest rate. As of 2026, the Ordinary Account (OA) earns 2.5% per year while the Special Account (SA) and MediSave Account (MA) earn 4% per year. The SA and MA also receive up to 1.5% extra interest on the first $60,000 of your combined balance for members aged 55 and below. To earn the most, you want to grow your SA and MA balances because they pay the highest guaranteed rate.

What Are the CPF OA, SA, and MA Accounts?

CPF money is not kept in one lump. When you and your employer make contributions, the funds are split into different accounts, each with a specific purpose and its own interest rate.

Ordinary Account (OA)

The OA is the largest account for most working Singaporeans. It is designed for housing, education, and certain approved investments. Because the money is meant to be flexible and easy to access for these uses, it earns the lowest interest rate of the three accounts.

Special Account (SA)

The SA is set aside for retirement and long-term investment. It is not meant to be touched until you retire, which is why it earns a higher interest rate. The SA was closed for members born after 1979 starting in 2025, which is an important recent change to understand.

When choosing between the OA, SA, and MA, the key question is not only which account pays more, but which account matches your current life stage. Young members may need OA funds for a housing down payment, while older members nearing retirement prioritize growing the SA balance to reach their retirement sum. Understanding the interest difference helps you make an informed decision that balances immediate needs with long-term growth.

MediSave Account (MA)

The MA pays for your healthcare needs, including hospital bills, MediShield Life premiums, and approved medical treatments. It earns the same base rate as the SA, making it one of the higher-yielding CPF accounts.

CPF Interest Rates 2026: Side-by-Side Comparison

Here is the current guaranteed base rate for each account. These figures apply across all ages unless otherwise stated.

Extra Interest on Balances

On top of the base rate, the government pays extra interest. For members aged 55 and below, you receive an additional 1.5% on the first $60,000 of your combined CPF balance, split between your OA and SA. This means the effective rate on the first $60,000 can reach 3.5% for OA funds and 5% for SA funds, capped at the $60,000 total.

For members aged 55 to 65, an additional 1% is paid on the first $30,000 of your retirement savings in the SA, on top of the 1.5% extra interest already mentioned. This layered structure rewards older members who keep their money longer.

Which CPF Account Has the Highest Interest in 2026?

The SA and MA both earn 4% per year, which is the highest guaranteed base rate among CPF accounts. The OA earns only 2.5%, so it is the lowest payer of the three.

If you are deciding where to put voluntary contributions or which balance to prioritize, the SA always wins on pure interest. However, your ability to move money is limited. You can transfer from your OA to your SA (an OA-to-SA transfer) to boost your retirement savings, but you cannot transfer money backwards from SA to OA. This is a one-way door, so you should be confident you do not need the funds for housing or education before transferring.

Comparing CPF Account Interest to Other Investments

CPF rates are guaranteed by the government, which makes them unusually safe compared to stocks or unit trusts. A 4% risk-free return is hard to find elsewhere in 2026, especially when bank fixed deposits offer lower rates.

To put this into perspective, a balance of $50,000 sitting in a Special Account keeps earning a guaranteed 4% every year, no matter what happens in the global markets. In contrast, a stock or REIT could fall sharply in a single quarter. This is why the CPF accounts are often described as the safest foundation of a Singapore retirement plan, and why the interest gap between the OA and the SA matters more than it may first appear.

For the first $60,000 of your combined balance, the effective return can reach 3.5% to 5%, which is better than most savings accounts and some fixed deposit products. This is why many financial planners advise keeping your SA and MA balances full rather than withdrawing or transferring to investments.

How CPF Interest Is Calculated and Credited

CPF interest is calculated on a monthly basis using the daily balance in each account, and it is then credited to your account once a year, at the end of the year. This compounding effect means that the earlier you start, the more your money grows, because every year's interest is added to your balance and starts earning its own interest the following year.

For 2026, the base interest rates have remained at 2.5% for the OA and 4% for the SA and MA. The government reviews the CPF rates to make sure the minimum guaranteed levels are maintained, and any income from the CPF investment framework is also used to ensure the rates stay at or above these floors. You do not need to do anything to receive the interest; it is added automatically.

Because the interest is credited annually, a member who keeps a high balance across all accounts benefits the most. The threshold for extra interest is calculated on your combined balance, so money sitting in a low-interest OA still counts toward the $60,000 amount that earns the higher effective rate.

Strategies to Maximize Your CPF Returns

1. Make an OA to SA Transfer

If you have surplus OA funds that you will not need for housing for many years, transferring them to the SA lets them earn 4% instead of 2.5%. The interest is compounded, so the gap grows over time.

2. Top Up Your SA Voluntarily

Voluntary top-ups to your SA (up to the retirement sum) also earn 4% and give you tax relief. This is a double benefit that most CPF members overlook.

3. Keep Combined Balance Above the Extra Interest Threshold

The extra interest applies to the first $60,000. Keeping your balance at or above this level ensures you capture the top rate on as much money as possible.

4. Use OA for Investments Only If Returns Are High

OA funds can be invested via the CPF Investment Scheme (CPFIS). However, remember that your OA already earns a guaranteed 2.5%. Any investment must beat that return after fees to be worth the risk.

5. Understand the SA Closure for Younger Members

Members born after 1979 no longer have a Special Account as of 2025. For these members, there is no SA to top up, so the retirement strategy shifts to the Retirement Account or other long-term vehicles. Check your own birth year and account status to know which rules apply to you.
