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.

Employer-agreed and personal voluntary contributions; the personal route needs no employer involvement, debits your bank account directly, and offers more flexible withdrawals.
