Always do your own due diligence, dun rely on what others assume they know the rules or try to put assumptions into your mind/thinking. It is always best to double confirm your understanding of the rules and the ultimate outcome for your case with CPF Board.
Are the calculators able to simulate the results of various scenarios?
Double or triple confirm your own understanding, what others say, what is written at be website (but is quite a useless website now compared to the old one).
How much will you get as payout RSS vs CPF Life?
What happens if you continue to topup RA after payout starts?
How long will payout last (under RSS per the new rules it is age 90, what if you continue to topup, can u request to extend the duration, can u request to increase or reduce the payout, etc) ( I cannot find much info at the website cos it is all to steer you towards CPF Life!
Under CPF LIfe, RA payouts (net of 10-20% premium) will last till age 90, thereafter payout comes from the pool from the premium plus interest). If she die at 90, she lose her interest on the premium (cost of insurance) in the pool, if she continues to topup after payout start, she lose more interest (cost of insurance) on additional premium in the pool.
Do some homework, calculate the estimated total payout under RSS and CPF Life by age 90, compare! Dun forget the cost of insurance! Calculate the estimated cost of insurance. Be prepared before you meet up with CPFB, as this is the most crucial meeting before she decides to kill her golden goose!
This is what I will do if it is my money.
Of course if you do not think you can support her (financially) till her last day, then kill the golden goose! But your family still need to give her emotional and other support, dun leave her alone with CPF Life.
Good luck to you!
