While it is a good plan, I think that CPF LIFE provides too little as the cost of living in Singapore is too high. One should just regard CPF LIFE as a baseline for a retirement target, and work towards 1M65 so that your retirement life can be worry-free. Even if you are unable to hit 1M65, hitting 500k at 65 years old will also help greatly.
I feel that our Government has done their best given the constraints of the FRS that we can put into the retirement account . WE have to help ourselves and work towards a great wealthy retirement.
