The Basic Retirement Sum (BRS) takes reference from a person's expenditure from a lower-middle retiree household, according to the latest
Household Expenditure Survey (HES). It assumes that the member owns a property that lasts him up to 95 and he does not need to pay rent in retirement.
The Full Retirement Sum (FRS) is set at two times of the BRS.
The
BRS or
FRS you need to set aside depends on when you turn 55 and is fixed for the rest of your life.
