Housing vs Retirement

Using CPF for your home is convenient — but you owe it back, with accrued interest. (CPF Board.)

Most Singaporeans use their Ordinary Account (OA) to help pay for a home. It is allowed and often sensible — but it carries a rule worth understanding: the accrued-interest rule. Any OA money you use for property must, when you sell, be refunded to your CPF together with the interest it would have earned had you left it there — 2.5% a year, compounded.

That "interest you owe yourself" grows quietly over decades. Use S$100,000 of OA towards a home and, twenty-five years later, you must return well over S$100,000 to your CPF on sale — money that then funds your retirement, not your next purchase. It is not a penalty; it is your own retirement saving being made whole. But it means a large CPF-funded home can leave less for retirement than the purchase price alone suggested.

The lesson is balance. Housing and retirement draw on the same pot, so leaning heavily on your OA for property trades future retirement income for present housing — a fair trade only when made with eyes open.

Illustrative example: the interest you owe back

The chart shows the accrued interest building up on S$100,000 of OA used for a home. Planning around it — rather than being surprised by it at sale — keeps the housing decision and the retirement plan in step.

Accrued interest is based on the OA floor rate (2.5% in 2026), which is reviewed periodically. Confirm current rules at cpf.gov.sg.
