CPF
CPF Ordinary Account (OA)
The CPF account you can use for housing, insurance, and approved investments, earning a guaranteed 2.5% floor.
What it is
In plain language.
The Ordinary Account is the most flexible of your three working-age CPF accounts. Each month a slice of your salary plus your employer's contribution flows in, and the balance earns a government-guaranteed minimum interest rate of 2.5% per year.
For most Singaporeans the OA is the workhorse account. It can pay your HDB or private property instalments, certain mortgage and home insurance, approved education fees, and it is the pool you can invest from under the CPF Investment Scheme.
Because the money is liquid for these approved uses while still earning a risk-free rate, the OA sits at the foundation of nearly every young Singaporean's balance sheet, whether or not they ever actively manage it.
How it works
In Singapore, in practice.
Contributions are automatic and split across OA, Special Account, and MediSave by an age-banded formula. Below age 55, the largest share of your CPF goes to the OA, with the proportion shrinking as you get older so more is steered toward retirement and healthcare.
The OA earns the higher of 2.5% or a pegged formula, and there is no tax on the interest. The first $60,000 of combined CPF balances earns an extra 1% (extra 2% on the first $30,000 from age 55), with the OA portion of that bonus capped at $20,000.
You do not buy the OA. It exists the moment you start working in Singapore as a citizen or PR. You can spend it only on CPF-approved purposes, or leave it to compound.

Leave it in CPF, or invest it?
Your CPF Ordinary Account earns a guaranteed 2.5% floor. Investing the same sum through CPFIS could earn more, or less. Projected, not guaranteed.
Where it sits
Its place in the instrument map.
A sound plan is built in layers, from a guaranteed base up to small, high-risk satellites. This is the role CPF Ordinary Account (OA) plays, and the layers around it.
Small, high-risk positions you could afford to lose entirely.
Direct stocks and REITs held for long-run growth.
Funds, ETFs, and bonds that spread risk across many holdings.
Government-backed income and the SRS tax wrapper.
Guaranteed and liquid: your CPF base and emergency cash sit here.
The trade-offs
What it does well, and what to watch.
Good for
- Every working citizen or PR, by default
- Funding a first home without draining cash savings
- People who want a guaranteed base return before taking market risk
Watch outs
- Money used for housing is no longer compounding at 2.5%, and you owe accrued interest back to your OA when you sell the property.
- OA cannot be freely withdrawn as cash before the withdrawal age and conditions are met.
- Investing OA only makes sense if you reasonably expect to beat 2.5% after fees, since you give up a guaranteed floor.
