Without SA interest or shielding, my projected retirement income will be depleted earlier and at around age 90 I will have nothing left except for CPF life payouts which obviously is not enough even at ERS level.
I'm going to push back on this a bit. The 2025 ERS will be $426,000. You're also allowed to add more funds to your Retirement Account every time the ERS is raised. These added funds still earn the same interest rate SA does (did) and feed into life annuity income on that basis (not for profit, low overheads, fair actuarial curves).
Let's assume a female (to model the lower payouts) turns 55 next year (2025) and somehow (cash, OA) puts $426,000 in her Retirement Account within her 55th birthday month. Then she does nothing else (no further top ups or transfers into RA, which she could do) except start CPF LIFE Escalating Plan payouts at age 70 (the default starting payout age). That'll generate $3,240 dollars (2040 dollars) per month for life, escalating at 2%/year to fight inflation. If you pull that $3,240/month back to 2024 dollars (at 2%/year inflation) that's like $2,360/month in today's dollars. If you have a paid-up HDB flat with a leasehold that runs to age 105+ then $2,360/month isn't too bad, is it? It's not luxurious, but I think it's enough for a basic and dignified lifestyle.
However, if that's not enough, no problem. Just buy more than $426,000 (2025) worth of CPF LIFE. During the 15 year period from age 55 to age 70 you should get 14 more opportunities to add funds to a Retirement Account. Assuming a 3% increase each year that's $12,780 you can add in the first year alone. Moreover, you could extend that window and only spend part of you CPF LIFE payouts from age 70 to 75 (for example), plowing some dollars back into RA (tracking the ERS) to keep boosting payouts.
In other words, if you're concerned about savings exhaustion — and you should be! — just buy more CPF LIFE at age 55 and in some number of years thereafter, and "backload" the payout stream as much as you can (via the Escalating Plan mainly). Bridge to this CPF LIFE package using other assets, invested prudently.
I'm single and will definitely need to be in a nursing home at that age. Can last abit longer if there is SA. Too bad, hope I don't live so long.
CareShield Life payouts would help "top up" your CPF LIFE income in this event. I think that'd make the nursing home math work at least with a modest subsidy (not even the most aggressive subsidies).
My opinion is there shouldn't be any CPF for PRs. However as a concession they can make voluntary contribution to CPF or SRS for tax deductions.
Do that and you make SPRs much more attractive as employees compared to Singaporean citizens. You also increase the burdens on general taxpayers in the future. That's because a big majority of those SPRs become citizens, and those naturalized citizens will have that many more problems with underfunded retirements since they wouldn't have as many years of contributions.
The government has already hugely bifurcated CPF between SPRs and Singaporean citizens. Singaporean citizens routinely get free money deposited into their CPF accounts periodically. SPRs don't. Elderly Singaporean citizens often qualify for matching funds. SPRs don't. SPRs have much greater difficulties using OA dollars for housing. They can't buy HDB BTOs at all (not without a Singaporean citizen in the household) and resale flats only after 3 years, and with lots of other restrictions (like a separate quota hurdle and marriage requirement). They also pay higher ABSD than Singporean citizens. On top of all that their compulsory CPF contribution rates are lower for the first two years.
Also, a lot of SPRs (probably most of them) are the spouses of Singaporean citizens. Whack SPRs and you hurt gobs of Singaporean citizen-based households, too.
In short, CPF is already a fundamentally different (and somewhat less attractive) arrangement for SPRs than it is for otherwise similarly situated Singaporean citizens. There's no repair required here. It's already bifurcated, with more benefits going to Singaporean citizens.
