The Central Provident Fund (CPF) is the cornerstone of retirement, housing, and healthcare financing for Singaporeans. One of the most attractive features of the CPF system is the interest rates it offers on member balances, which are typically higher than what you would earn from bank deposits. In this 2026 guide, we explain the interest rates for all four CPF accounts, how they are determined, and how you can maximize the interest you earn.
Overview of CPF Accounts and Their Purpose
The CPF system comprises four main accounts, each serving a different purpose. The Ordinary Account (OA) is primarily used for housing, education, and investment. The Special Account (SA) is dedicated to retirement savings. The MediSave Account (MA) is used for healthcare expenses, including hospitalization and approved medical insurance. The Retirement Account (RA) is created when you turn 55 and combines your SA and OA savings (up to the Full Retirement Sum) to fund your retirement payouts.
Understanding the interest rates for each account is essential for effective financial planning. The Central Provident Fund Board (CPF) reviews and publishes these rates quarterly, based on established formulas linked to market interest rates.
Ordinary Account (OA) Interest Rate in 2026
The OA interest rate is pegged to the three-month average of the local major banks' interest rates, subject to a legislative minimum rate. The formula takes the average of the one-month, three-month, six-month, and twelve-month deposit rates, plus the savings rate from the three local banks (DBS, OCBC, UOB). The OA rate is reviewed quarterly in January, April, July, and October.
Due to the legislative floor, the OA interest rate has remained at 2.5 percent per annum for many years. This floor ensures that CPF members earn a guaranteed minimum return on their OA balances, regardless of how low market interest rates may fall. In 2026, the OA interest rate continues to be 2.5 percent per annum.
While 2.5 percent may not sound extraordinary, it is significantly higher than what most savings accounts at commercial banks offer, which typically range from 0.05 percent to 0.5 percent per annum. The OA rate is also risk-free, as it is backed by the Singapore government.
Special Account (SA), MediSave Account (MA), and Retirement Account (RA) Interest Rates
The SA, MA, and RA interest rates are pegged to the 12-month average yield of Singapore Government Securities (SGS) plus 1 percent. These rates are also subject to a legislative floor of 4 percent per annum. The Singapore Government Securities (SGS) yields are published by the Monetary Authority of Singapore and reflect the cost of government borrowing.
Due to the 4 percent floor, the SA, MA, and RA interest rates have remained at 4 percent per annum for an extended period. In 2026, these accounts continue to earn 4 percent per annum. This floor is currently guaranteed until at least 31 December 2026, providing CPF members with certainty about their returns.
The 4 percent rate is highly competitive, especially when compared to fixed deposit rates at commercial banks, which typically range from 1.5 percent to 3 percent per annum in 2026. The SA, MA, and RA rates offer a guaranteed, risk-free return that is difficult to match with comparable investments.
Extra Interest on the First $60,000
In addition to the base interest rates, CPF members earn extra interest on the first $60,000 of their combined account balances. This extra interest is 1 percent per annum, bringing the effective interest rate on the first $60,000 to 3.5 percent for OA balances and 5 percent for SA, MA, and RA balances.
Of the $60,000 cap, up to $20,000 can come from the OA. This means that if you have $20,000 in your OA, that portion earns 3.5 percent interest (2.5 percent base plus 1 percent extra). Any OA balance above $20,000 earns the standard 2.5 percent rate. Similarly, SA, MA, and RA balances earn 5 percent on the first $60,000 of combined balances, then 4 percent on amounts above that.
This extra interest is a powerful incentive for CPF members to maintain and grow their balances. Over time, the compounding effect of the extra interest can add thousands of dollars to your retirement savings.
How CPF Interest Rates Are Determined
The CPF interest rate formulas are set by legislation and are designed to reflect prevailing market conditions while providing a minimum guaranteed return. The OA rate is pegged to local bank deposit rates, ensuring that it moves in line with the broader banking sector. The SA, MA, and RA rates are pegged to SGS yields, which reflect the government's cost of borrowing and are considered a benchmark for risk-free returns in Singapore.
The legislative floors of 2.5 percent for the OA and 4 percent for the SA, MA, and RA ensure that CPF members always earn a minimum return, even when market interest rates are low. These floors have been in place for many years and have been periodically reviewed and extended by the government.
The government also reviews the extra interest rate structure periodically. The current 1 percent extra interest on the first $60,000 has been in place since 2008 and has been extended multiple times, most recently through 2026. This commitment reflects the government's emphasis on helping Singaporeans build their retirement savings.
CPF Interest Rate Floor vs Bank Rates
One of the most compelling reasons to keep your money in CPF rather than in a bank is the interest rate advantage. As of 2026, the OA earns 2.5 percent and the SA, MA, and RA earn 4 percent (or 5 percent on the first $60,000). Compare this to typical bank savings accounts, which offer 0.05 percent to 0.5 percent, and fixed deposits, which offer 1.5 percent to 3 percent.
Even the best promotional fixed deposit rates rarely exceed the CPF rates for sustained periods. Moreover, CPF interest is risk-free and does not require you to lock up your funds for a specific term, as fixed deposits do. The interest is credited annually into your CPF accounts and compounds automatically.
For members considering investing their OA balances through the CPF Investment Scheme (CPFIS), it is important to remember that any investment returns must exceed the OA interest rate of 2.5 percent to be worthwhile. Many CPFIS investments fail to beat this benchmark consistently, especially after accounting for fees and expenses.

Strategies to Maximize Your CPF Interest
Transfer OA Funds to SA
One of the most effective strategies to boost your CPF interest earnings is to transfer funds from your Ordinary Account to your Special Account. Since the OA earns 2.5 percent and the SA earns 4 percent (or 5 percent on the first $60,000), this transfer immediately increases your interest rate by 1.5 percentage points on the transferred amount. Over a long time horizon, this difference compounds significantly.
For example, transferring $50,000 from OA to SA increases your annual interest from $1,250 to $2,500, a difference of $1,250 per year. Over 20 years, assuming no further contributions, the additional interest alone could grow to more than $30,000 due to compounding.
However, note that OA-to-SA transfers are irreversible. Once the funds are in your SA, you cannot transfer them back to your OA. Consider your housing and other needs before making this transfer.
Make Voluntary Cash Top-Ups
You can make voluntary cash top-ups to your SA or RA (up to the Full Retirement Sum). These top-ups earn 4 percent or 5 percent interest, making them an attractive option for surplus cash that would otherwise sit in a low-interest bank account. Cash top-ups to your RA may also qualify for tax relief of up to $8,000 per year.
The combination of high interest and tax relief makes cash top-ups one of the most efficient ways to accelerate your retirement savings. If you are a higher-income earner, the tax savings alone can add significant value.
Retain Funds in MA and SA
Some CPF members are tempted to withdraw from their MA or SA for non-essential purposes, such as paying for elective medical procedures or investment schemes. Keeping your balances in these accounts allows you to continue earning the higher 4 to 5 percent interest. For healthcare-related decisions, understanding the CPF Basic Healthcare Sum is essential, as covered in our CPF Basic Healthcare Sum Singapore guide.
Maximize the Extra Interest on the First $60,000
To get the most out of the extra 1 percent interest on the first $60,000, ensure that your combined balances across all accounts remain above this threshold. If you are using your OA for housing, try to maintain at least $20,000 in your OA so that you do not deplete the portion eligible for extra interest.
Comparing CPF Interest with Other Investments
While the CPF interest rates are attractive, they may not always outpace inflation over the long term. The OA rate of 2.5 percent and the SA rate of 4 percent are competitive, but Singapore's long-term inflation rate has historically averaged around 2 to 3 percent per annum. This means your real return (after inflation) on the OA is modest, while the SA offers a more comfortable real return.
For younger members with a longer investment horizon, it may make sense to invest a portion of your OA savings through CPFIS in diversified, low-cost index funds or ETFs. However, this approach carries investment risk and should be undertaken only after careful consideration of your risk tolerance and financial goals.
For most members, especially those closer to retirement, the guaranteed CPF interest rates provide the best balance of return and safety. The risk-free nature of CPF interest, combined with the government backing, makes it an excellent foundation for any retirement portfolio.
Final Thoughts on CPF Interest Rates in 2026
The CPF interest rates in 2026 continue to offer Singaporeans an attractive and risk-free way to grow their savings. The OA rate of 2.5 percent, the SA, MA, and RA rates of 4 percent, and the extra 1 percent on the first $60,000 combine to make CPF one of the best savings vehicles available in Singapore.
By understanding how these rates work and implementing strategies to maximize your interest earnings, you can significantly boost your retirement savings over time. Whether you are just starting your career or approaching retirement, the CPF system provides a powerful tool for building long-term financial security. Take the time to review your CPF balances, consider making voluntary contributions, and consult a financial advisor if you need help optimizing your CPF strategy for your specific circumstances.
