CPF Ordinary Account (OA)

The CPF account used for housing, education, investments, and insurance. Earns 2.5% guaranteed interest (with an extra 1% on the first S$20,000). Most HDB and bank-loan mortgages are paid from OA.

What CPF OA is

The Ordinary Account is the most-used of your four CPF accounts. It funds housing, education, approved investments, and selected insurance premiums.

OA earns a guaranteed 2.5% interest per annum, with an extra 1% on the first S$20,000 (combined with other CPF balances). The rate is reviewed quarterly but has been stable since the 1990s.

Contribution flow

For employees under 35, ~62% of each month's CPF contribution flows into OA. This share steps down with age — by 50, OA receives ~37% while SA and MA take larger shares.

The Ordinary Wage ceiling caps monthly contributions on the first S$7,400 of wages (S$8,000 from 2026). Annual contributions are also capped via the Additional Wage ceiling.

What you can use OA for

Housing: downpayment and monthly instalments for HDB flats or private property. Both HDB concessionary and bank loans can be paid from OA.

Education: pay your own, your child's, or your spouse's tuition fees at approved institutions. Must be repaid into CPF with interest after graduation.

Investments: CPF Investment Scheme (CPFIS-OA) allows investing OA above the first S$20,000 into approved unit trusts, ETFs, shares, and gold.

Insurance: Dependants' Protection Scheme, MediShield Life (top-up only), Home Protection Scheme premiums.

OA strategy choices

Use it for property: most Singaporeans tap OA aggressively for housing. The trade-off is forgoing 2.5% guaranteed compounding and triggering 'accrued interest' that must be returned to CPF on sale.

Transfer to SA: irreversible. Moves money from 2.5% to 4% guaranteed. Smart for those building retirement income who don't need OA for housing.

Invest via CPFIS: historically, most CPFIS-OA investors underperformed the 2.5% benchmark after fees. The bar is higher than it looks; broad ETFs with low expense ratios are the safer choice.

Frequently asked questions

What is the CPF Ordinary Account (OA)?

The CPF account used for housing, education, investments, and selected insurance premiums. It earns 2.5% guaranteed interest (with an extra 1% on the first S$20,000 combined balance). Most working Singaporeans tap OA heavily for HDB or condo mortgage payments.

What can I use CPF OA for?

Housing (downpayment and monthly mortgage), education at approved institutions (subject to repayment with interest), CPFIS-approved investments after the first S$20k, and certain insurance premiums (Dependants' Protection, Home Protection, MediShield Life top-up).

Should I transfer OA to SA?

It's irreversible but immediately upgrades the return from 2.5% to 4%. Best done in your 30s – 40s if you don't need that OA for housing. The trade-off is permanent lockup in retirement-account land.

What share of monthly CPF contributions goes to OA?

About 62% for employees under 35. The share steps down with age — by 50 it's ~37%. The remainder goes to SA and MA, with allocation tilting toward retirement saving as you age.
