You are right. The annual top ups will never have as great an ROI as the initial ERS you put in. But likely the ROI will still be very good compared to other annuities.I plan to top up ers (once) when I reach 55 to max the compounding effect since it is a 'large' sum compounded over 10 years.
I would like to ask if it is worth it to top up the 'smaller' sum yearly (from 56 yo onwards) since the quantum is smaller and duration is also shorter (to 65 yo), as such it wouldn't have made such a great difference from the ROI point of view. Since I will likely not see the entire top up amount in my life time, I thought I would just top up once max at 55 yo.
If one were to top up ers at 55, what would be the best time to do so? Immediately when RA is formed or wait till early of the year?
And I guess the impt question is what you think of the additional payout.
I.E. If the additional payout is impt to you or not.
I did some calculations for payouts that start from 70, and ERS at 55 is actually very comparable to FRS at 55 + annual top up to FRS.
Another advantage of keeping at FRS is also the available tax relief for yourself or your family when you top it up every year.
As for which plan, you don't have to decide on that until you want your payout to start.
