CPF Allocation by Age
What is CPF Allocation Ratio by Age?
▾
Ever wondered where your hard-earned money goes after it leaves your payslip? If you live and work in Singapore, a chunk of your salary goes straight into your Central Provident Fund (CPF). But here is the twist: it does not just sit in one big pile. Instead, the government automatically splits your monthly contributions into three separate buckets: your Ordinary Account (OA), Special Account (SA), and MediSave Account (MA). How they split this money depends entirely on how old you are. Think of these accounts like a smart savings strategy designed for different stages of your life. When you are younger, say in your 20s or early 30s, the system channels more of your money into your OA. Why? Because that is the time you are most likely planning to buy your first home or pay off university loans. As you blow out more birthday candles, the focus shifts. The system starts redirecting a larger slice of your pie into your SA and MA to build up your retirement nest egg and cover healthcare costs. This calculator is your personal financial roadmap. By showing you exactly how your monthly CPF contributions are sliced and diced, it helps you answer the big questions in life. Can I comfortably afford that new BTO flat's monthly mortgage? How fast is my retirement fund growing? Do I have enough in my healthcare account to cover insurance premiums? Instead of guessing or digging through complicated government tables, you can instantly see where every single dollar is going and plan your future with absolute confidence.

How to CPF Allocation Ratio by Age

- 1Grab your current age and your total monthly CPF contribution (this is the combined amount from both your own salary and your boss's matching contribution).
- 2Locate your age bracket on the official CPF allocation ladder to find your specific percentage split.
- 3Multiply your total monthly CPF cash by your Ordinary Account (OA) rate to see your housing and investment budget.
- 4Multiply the total by your Special Account (SA) rate to find out what is going directly into your retirement fund.
- 5Multiply the total by your MediSave Account (MA) rate to see how much is set aside for healthcare and insurance premiums.
- 6Watch how these balances grow over time as they compound monthly with guaranteed interest rates (2.5% for OA and 4% for SA and MA).
- 7Add in the extra 1% bonus interest that the government pays on your first $60,000 of combined savings to get your true total growth.
Worked Examples
▾
Age ≤35 allocation: OA 23%, SA 6%, MA 8% of ordinary wages
At 26, you're likely thinking about buying a home soon. The system puts the lion's share ($805) into your OA to help with down payments, while starting your retirement and healthcare pots with $210 and $280.
Age 36–45 allocation: OA 21%, SA 7%, MA 9% of ordinary wages
As you hit your late 30s, the system starts gently shifting focus. Your housing account gets a slightly smaller piece, while your retirement (SA) and healthcare (MA) pots get a boost to prep you for the future.
Age 46–55 allocation: OA 13%, SA 11.5%, MA 12.5% of ordinary wages
In your 50s, the game changes. Since your house is likely paid off or close to it, your OA drops to $780. Meanwhile, your retirement and medical accounts get a massive injection of $690 and $750 to secure your golden years.
Age 55–60 allocation: OA 10.5%, SA 3.5%, MA 2.5% of ordinary wages
Once you pass 55, the total contribution rates drop. With a lower overall rate, your money is split to keep your housing payments stable while ensuring your healthcare pot ($100) and retirement pot ($140) continue to tick upward.

Special Cases
▾
Crossing the Age Threshold Mid-Year
When you celebrate a milestone birthday that pushes you into a new age band, your allocation rates change starting from the month after your birthday. Don't worry if your payslip looks slightly different; the system updates your rates automatically.
Reaching the Basic Healthcare Sum (BHS)
If you've been diligently saving and your MediSave hits the BHS cap, your MA contributions will overflow into your SA (or RA if you are over 55). This is a fantastic milestone because it accelerates your retirement compounding.
Self-Employed Contribution Rules
If you run your own business or do freelance work, you aren't required to contribute to OA or SA, but you must contribute to your MediSave. The allocation rules here are different and depend on your net trade income.
Reaching Age 55 and the RA Creation
At age 55, a brand-new account called the Retirement Account (RA) is born. The CPF Board automatically sweeps savings from your SA, then your OA, to fill this new bucket up to your retirement sum, which changes your allocation landscape completely.

| 60 – 65 | 3.5% | 2.5% | 2.5% | 8.5% approx |
| 65 – 70 | 1% | 1% | 2.5% | 4.5% approx |

Frequently Asked Questions
▾
Why does my housing account (OA) get smaller as I get older?
Think of it as the system adapting to your life stages. When you are young, you need housing cash to buy your first home. As you grow older, you are likely settling your mortgage, so the government automatically redirects more of your hard-earned money to your retirement and medical accounts. This ensures you aren't house-rich but cash-poor when you stop working.
Can I manually change how my monthly CPF money is split?
Unfortunately, no. The allocation percentages are fixed by the CPF Board based on your age bracket. However, you can manually transfer money from your OA to your SA if you want to speed up your retirement savings. Just remember that this transfer is a one-way street and cannot be undone!
What happens to my MediSave contributions once it hits the limit?
This is a great problem to have! Once your MediSave Account reaches the Basic Healthcare Sum (BHS), it stops accepting new funds. Any extra money that would have gone into your MediSave overflows automatically. If you are under 55, it goes into your Special Account; if you are 55 or older, it flows into your Retirement Account, boosting your retirement nest egg.
Why does my total CPF contribution rate drop after I turn 55?
The drop is designed to make older workers more attractive to employers by lowering the cost of hiring them. While it means less money goes into your accounts monthly, it helps keep senior workers employable. To make up for this, the interest rates on your remaining balances are highly optimized to keep your savings growing.
Is it a good idea to move my OA savings to my SA?
It depends on your immediate goals. Moving money from OA (earning 2.5%) to SA (earning 4%) gives you a guaranteed interest boost. However, once that money moves, you can never use it for housing or education again. If you have already paid off your home and have cash to spare, it is an amazing way to supercharge your retirement fund.
What is this 'extra 1%' interest everyone talks about?
To help middle- and lower-income earners, the government pays an extra 1% interest on the first $60,000 of your combined CPF balances (with a cap of $20,000 from your OA). If you are 55 or older, they even pay an extra 2% on your first $30,000! It is essentially free money, so keeping your balances healthy pays off big time.
How is the interest calculated and when do I actually see it?
Your CPF interest is calculated monthly, based on the lowest balance in your account for that month. However, you won't see it drop into your account every 30 days. Instead, the interest is credited to your accounts in one lump sum in December of every year, making for a very nice year-end bonus!
Common Mistakes to Avoid
▾
- !Thinking your monthly CPF is just one big pool of money instead of three uniquely restricted accounts.
- !Moving funds from OA to SA to get higher interest without realizing you might need that OA money for a home downpayment next year.
- !Forgetting that your employer's contribution is already factored into your total CPF allocation, leading to double-counting your budget.
- !Assuming your MediSave contributions keep building forever without realizing they cap out and overflow once you hit the Basic Healthcare Sum.
Pro Tip
If you have already secured your home and do not need your OA for mortgage payments, consider transferring your OA funds to your SA. Moving your money from 2.5% to 4% interest might not sound like much, but over 20 years, compounding can easily turn a small transfer into an extra five-figure sum for your retirement!
