Before we invest our CPF OA in T-bills, we should maximise the returns on our combined CPF balances first. CPF members below 55 years old can earn an extra 1% interest or up to 5% on the first $60,000 of their combined balances (capped at $20,000 for OA).
Similarly, CPF members aged 55 and above can earn up to 6% interest on the first $30,000 of their combined CPF balances and up to 5% on the next $30,000.
