MPF voluntary contributions invest in the scheme’s constituent funds with lower fees than retail funds — no initial or redemption charges, and monthly amounts from a few hundred dollars. With Hong Kong inflation averaging 5% over 20 years, HK$20,000 of purchasing power needs HK$53,000 two decades later; voluntary top-ups help you keep up.
Employer-agreed and personal voluntary contributions; the personal route needs no employer involvement, debits your bank account directly, and offers more flexible withdrawals.
