Detailed statutory analysis & overview
CPF is often described as a savings rate, but it is really four accounts with different interest rates, different permitted uses, and a split between them that changes as you age. Every dollar contributed is allocated across the Ordinary Account, which funds housing, education, insurance, and investment, the Special Account for retirement, and MediSave for approved medical costs and health insurance premiums. The allocation is not fixed: the Ordinary Account share is largest in your twenties and shrinks steadily as the MediSave share grows, so two employees on identical salaries twenty years apart build very different balances. At 55 a Retirement Account is created and, following a change effective from January 2025, the Special Account is closed for members who have turned 55, with its savings moved to the Retirement Account up to the Full Retirement Sum and any excess to the Ordinary Account. This tracker models the monthly split, the account allocation, and the tiered interest that quietly does most of the compounding work.
