I don't need all contribution goes to RA (if below FRS), like that those still have housing loan to pay how?
For members age 55+ but below 60 who have not yet met the Full Retirement Sum (with money, or with a combination of money and up to half in qualifying property), 35.3% of compulsory contributions (and VC3As) flows into their OAs.
For example, in 2026 if you're in that age bracket, employed, earning S$5,000 per month, and haven't met the FRS yet, you should see about S$600 per month flow into your OA. That contrasts to about S$750 per month in the age bracket before 55, with the same assumptions.
However, this hypothetical employee's monthly gross take home pay would increase by S$100 at age 55 in 2026. This part is going to be phased out, so next year (2027) it'll be S$50 higher gross monthly income with this hypothetical worker.
If the reduction in OA inflow (net of the higher take home pay in 2026 and 2027) means that the mortgage payment cannot be met, the same basic choice that everyone has is available: sell the home, find less expensive housing. Then the tepid RA "guardrail" makes perfect sense in this situation: "mortgage/house too big, pension too small." There are competing financial priorities, and the pension priority ought to prevail at some basic level, at some point.
