Formula for CPFLIFE Payout calculator
I asked CHATGPT to provide a formula for female: * to compute the CPFLIFE monthly payout from age 65 to 70 * based on RA balance at $500k to $1,000k. * Assuming yearly topup to its yearly ERS limit, till age 70. * Basic Plan: The formula is: At 65: Monthly payout ≈ 0.51% of RA Each year delayed (with ERS top-ups): Multiply previous payout by ~1.10 ~~~ based on above true payout case at your 6% p.a. payout rate: CPFLIFE monthly Basic Plan payout: 0.51% of RA Balance @age 65 = Payout@65 . Each year delay in payout, which one continues to topup to its yearly ERS Limit: Payout@65 x 1.1 ~~~ Check: RA Balance @age 65: $535,000 CPFLIFE monthly payout = 0.51% of $535,000 = $2728.5 p.m. (= which matches the true payout of the 67yo female case)
