Starting MPF early pays: a 10-year head start was worth HK$1.11 million

This article is a rewrite of a report from July 2012.

The greatest force in long-term investing is not picking the right fund — it is time. MPF is a long-term investment, and the earlier you start managing it, the bigger the time advantage. The numbers show how much five late years can cost.

What is the MPF contribution rate?

Employers and employees each pay 5% of relevant income; the self-employed pay 5% of income. Under the revised 2012 ceiling, the monthly maximum was HK$1,250:

How much does a five-year delay cost?

Assuming HK$25,000 monthly income and 5% annual returns, starting at 20 and contributing to 65 built about HK$2.53 million; starting at 25 yielded only HK$1.91 million — HK$75,000 less in contributions, HK$620,000 less in balance. Starting at 30 meant HK$1.42 million at 65, a HK$1.11 million gap versus starting at 20.

Why does time matter so much?

Compounding plus dollar-cost averaging. Interest folds back into principal and reinvests; fixed monthly contributions buy fewer units when prices are high and more when low, smoothing costs over time. Time is MPF’s best partner — and since the system does not let you stop contributing when markets sour, that enforced discipline is itself an advantage.
