Why are CPF LIFE monthly payouts lower for women than men?

CPF LIFE Payouts and Gender Differences

CPF LIFE monthly payouts are generally lower for women than for men primarily due to differences in life expectancy, as mandated by the CPF Board. CPF LIFE is designed to provide payouts for as long as you live, pooling longevity risk across cohorts. Since women in Singapore, on average, have a longer life expectancy than men, the same retirement sum in the Retirement Account (RA) must be spread over a longer expected payout period, resulting in lower monthly payouts.

Mechanism of Payout Calculation

The monthly payout amount is calculated based on the balance in your RA when you start your payouts (from age 65) and the prevailing CPF LIFE plan chosen. A larger accumulated sum leads to higher payouts. However, for the same RA balance, the payout formula inherently accounts for the longer expected lifespan of women.

Impact of SA Closure and Interest Rates

While the SA closure in 2025 standardizes the system (OA at 2.5%, RA at 4%), and interest rates like the guaranteed 4% floor on the RA remain the same regardless of gender, these factors do not override the fundamental actuarial difference based on life expectancy used in the CPF LIFE payout calculation tables. For example, money in the RA earns 4% interest, and this balance forms the basis of the payout calculation starting at age 65.

Withdrawal at Age 65

It is important to note that at age 65, individuals can withdraw up to 20% of their RA balance (excluding top-ups, grants, etc.). The remaining balance is used for CPF LIFE. The lower payout for women is a direct consequence of actuarial science applied to ensure the monthly income lasts for their entire lifetime, aligning with the principle of providing lifelong income (CPF Board information).
