How Deferring Works
CPF LIFE payouts can start at any time from 65 to 70. CPF says that for each year you wait, your monthly payout rises by up to 7%, and by up to 35% if you wait until 70. The savings stay in your Retirement Account in the meantime and keep earning interest, which is what pays for the higher amount.
Waiting means giving up the payouts you would have had in those years. The break-even age is when the bigger later payouts have made up for that. Live past it and the later start pays more in total; die before it and starting at 65 would have paid more. At the full 7% a year, starting at 70 on the Standard Plan catches up at about 84.
Total dollars are not the whole story. A larger monthly payout protects more against a long life and rising prices, while an earlier start helps if you need the income at 65 or have no other savings. Your health, your other income and whether you are still working all matter, and this tool shows only the arithmetic.
