This depends on the duration you choose – for all three duration options, the maximum age you can be at the end of the duration is 70 years old (i.e. the maximum end date is the day before your 71st birthday). Therefore the maximum ages for the three durations are as follows:
10-year plan: 60 years old
15-year plan: 55 years old
20-year plan: 50 years old
So if you are currently in your 50’s and don’t have any pension plan, at least you still have some time left to save for retirement – but you’re going to be working longer. If you’re young, start early! Then you can retire early… Anyone who is 18 or older can start a pension plan.
