Recently, my brother in law who is 68yo and under old RSS, was also given an amount to last 28 years when he started his payout.
This seems to be the default CPF option ie giving the minimum payout to last the maximum duration.
This is similar to recent case mentioned here :

What surprises me most is CPF's answer, that "we are unable to adjust monthly payout to last 20 years as it will deplete his RA prematurely" ...
Would appreciate if experts can explain or provide some insight .. thanks
My understanding is that for those on RSS, the payout amount shld last at least 20 years from the Payout Eligibility Age for that cohort ..
CPFB explained in their FB page, your RA (principle) will be paid over 20 years, the extra 8 years is for payout of interest earned on RA. Wow that is not bad, interest earned on RA can last u another 8 years wor!

). My guess is about 2 years or thereabout.
