OA Interest Rate
The CPF Ordinary Account earns a minimum of 2.5% per annum, guaranteed by the Singapore government. The rate is reviewed quarterly, pegged to the 3-month average of major local banks’ savings rates with a 2.5% floor. As at Q1 2026, the OA rate remains at 2.5% p.a. OA funds can be used for housing (HDB/private property), education, investment via CPFIS-OA, and insurance premiums.
SA Interest Rate
The CPF Special Account earns a minimum of 4% per annum — 1.5 percentage points higher than OA. The rate is pegged to the 12-month average yield of 10-year Singapore Government Securities plus 1%, subject to a 4% floor. SA funds are earmarked for retirement with restricted uses (cannot be used for housing). Note: As of 1 January 2025, the SA is closed for members aged 55+. See CPF SA Closure 2025.

OA to SA Transfer
Members below 55 can voluntarily transfer OA funds to SA via the CPF Board portal. This transfer is one-way and irreversible. S0,000 in OA at 2.5% grows to ~S0,000 over 20 years; the same in SA at 4% grows to ~S10,000 — a S0,000 compounding difference. See CPF OA to SA Transfer Singapore for details.
Extra Interest on First S0,000
CPF members earn an extra 1% on the first S0,000 of combined CPF balances (capped at S0,000 for OA). Members aged 55+ earn an extra 2% on the first S0,000 and 1% on the next S0,000. This extra interest is credited to the SA or RA. See CPF OA Interest Rate for additional context.
