The interest earned on yr RA Account doesn't go to yr beneficiaries....
OK, I think you're confused, misinformed, or both.
First of all, can we agree that your CPF nominee(s) receive all remaining funds in your Retirement Account (and other CPF subaccounts) if you were to die before starting CPF LIFE payouts, which could be as late as age 70 -- including all interest? Assuming you understand that part, let's continue....
only the principal minus the total monthly CPF life payouts that one has gotten from CPF Life. The interests earned will go to the pool to support those who will exceed the breakeven age which I believe must be more than 85 yrs old. Someone did the Maths - breakeven is 90+
Let's assume you choose the CPF LIFE Basic Plan. That's not a recommendation, but I'm using that plan as an example since it's quite easy to explain. Let's choose some "worst case" assumptions:
1. You start payouts at age 65.
2. CPF deducts 20% (the maximum possible) of your Retirement Account at age 65 and places it in the CPF Lifelong Income Fund as longevity insurance for age 90+.
3. You die at precisely the age that minimizes the net effective yield on your Retirement Account -- the "worst" time from a pure investment point of view.
OK, got all that? And what do you and your nominees end up with? You still end up earning 3.X% interest. (The exact X is a little hard to calculate, but it's well above zero.)
Yes, you could withdraw Retirement Account funds if you want to, if you fear the absolute worst case interest rate result for you and your nominees. But you'd be trading 3.X% interest for 2.5% interest, even if you could do that. That would not be smart.
For my case, $176K (FRS) will be deducted for the RA account, regardless of my intention to pledge the HDB.
With the CPF LIFE Escalating Plan and Standard Plan, yes. With the CPF LIFE Basic Plan, no. (Again, not a recommendation, just a point of fact.)
Once upon confirming the HDB pledge (between 55 - <65), the 50% of the FRS will be released to yr personal bank account- it will not be credited into Yr CPF OA which I would prefer.
You may prefer that, but that's not an option I'm afraid. Or at least it's no more of an option than it is for any other cash.
