630/mth x 17 years (RSS) equivalent is 560/mth x 19years (cpf life).It depends a little on the payout plan chosen, but the residual for his nominee(s) is guaranteed to be at least equal to this amount: the principal (at the start of CPF LIFE) less CPF LIFE payouts. For example, if he enters CPF LIFE at age 70 with $70,000 in his CPF Retirement Account, lives for 10 years, and receives $560/month, then that's $67,200 of CPF LIFE payouts. His CPF nominee(s) are guaranteed to receive at least $2,800 ($70,000 minus $67,200) in this example. (Adjust the numbers for real numbers -- $70K is most probably substantially wrong for the payout figure you cited.) Plus remaining OA, SA, and MA balances of course.
No, the interest helps pay for the (important!) lifetime payout guarantee, subject to a little variation depending on payout plan chosen. "There's no free lunch." Of course with both the classic RSS and CPF LIFE the residual falls every month, and there's no guarantee there will be any residual from RA/CPF LIFE. If he merely lives long enough there's no residual from that source. The key difference is that CPF LIFE payouts don't end until he does, and classic RSS payouts end on a fixed date even if he doesn't.
If he's in average or better health there are rather high odds he will outlive a 17 year classic RSS payout. Singstat publishes national life tables that give some idea, although they're too conservative for forward projections since they're based on past mortality experiences.
which will be 87yo and 89 yo. ignoring this longevity thingy
the clarity i need for the "remaining" if pass on earlier.
RSS: cpf balance + interests earned - disbursed amount.
Is this correct?
CPF:
cpf balance + interest earned + (cpf-life premium balance + cpf-life premium balance interest earned ) - disbursed amount ?
your response is : cpf balance + interest earned (OA/SA/RA) + (cpf-life premium balance ) - disbursed amount
Is this correct?
