If we take 2023 as the year when the member turns 55, topping up to ERS each year until 65 should take an extra 120k.
This is a rough figure. ERS for the next 5 years (I think) is known on the CPF website. The rest is assumed.
If you take the known figures, the increase is roughly by 3.5% each year. So you can work that out.
The final figure in your RA if you don't top-up, would be (($298,200 x 1.04) + 900) for however many years until you decide to start CPF Life.
Roughly $450k at 65. About $555k at 70.
If you do top-up annually,
Roughly $595k at 65. About $815k at 70.
Using Standard Plan as comparison.
No Top-Up & Start at 65 gives you roughly $2,410 / mth.
Top-Up & Start at 65 gives you roughly $3,160 / mth.
I'll just do that Start at 70 as well.
No Top-Up & Start at 70 gives you roughly $3,230 / mth.
Top-Up & Start at 70 gives you roughly $4,720 / mth.
(This last figure is an extrapolation. CPF Life calculator does not allow a figure in RA larger than $800k.)
