HK$2,120 at 25: A Fresh Starter’s 40-Year DCA Sandbox — Starting Five Years Late Costs HK$1.79 Million

The MPFA released its latest provisional figures yesterday (6 October): for the 12 months to end-September, MPF equity funds averaged 10.3%, mixed-asset funds 8.5%, and the Default Investment Strategy’s Core Accumulation Fund 9.5% — while bond funds lost 1.5% on average, the worst of the lot (i-CABLE, citing the MPFA). Career starters tend to react in one of two ways: chase the equity number, or shrug that a HK$20,000–30,000 balance makes fund choice irrelevant.

Both reactions are wrong, and for the same reason: they treat MPF as a fund-picking contest instead of a time contest.

Reframing: your biggest asset is not stock-picking skill — it is your age

A 25-year-old earning HK$21,200 a month (Hong Kong’s median monthly employment earnings, May 2026) contributes 5% as employee plus 5% as employer: HK$1,060 + HK$1,060 = HK$2,120 a month, HK$25,440 a year. After year one the account holds roughly HK$25,000. An equity fund’s 10.3% on that is HK$2,600; a bond fund’s -1.5% is a HK$380 loss — the gap barely covers a nice dinner. First-year return gaps are peanuts; the allocation choices of the first five years are the watermelon.

Fresh starters carry two fatal cognitive traps:

First, “too small to bother” — the balance is tiny, so the allocation is random, and seriousness can wait a few years. The sandbox below prices that wait at HK$1.79 million.

Second, “chase last year’s champion” — 10.3% flashes on screen and the instinct is to go all-in on equities; -1.5% flashes and bonds get blacklisted for life. But a 12-month figure is weather, not climate. Bond funds lost money this past year precisely because the Fed hiked 25bp in September and the 30-year Treasury yield climbed to 5.6%, a 24-year high — when yields rise, bond prices fall; they are two sides of one coin. Setting a 40-year allocation off one year’s weather is the market timer’s most expensive habit.

The sandbox: HK$2,120 a month, three endings over 40 years

Same 25-year-old, same HK$2,120 monthly contribution, contributing to age 65 (40 years). Total contributions: HK$1.018 million. Three annualised-return scenarios, all illustrative:

Scenario A — growth tilt (7.3% p.a.): HK$5.67 million. This is not fantasy: 7.3% is the Core Accumulation Fund’s actual annualised net return since its April 2017 launch (MPFA Chairwoman Ayesha Macpherson Lau’s August 2026 blog). Net of contributions, compounding contributes about HK$4.65 million.

Scenario B — balanced (5% p.a.): HK$3.14 million. Close to the long-run annualised returns of equity and mixed-asset funds since the system’s inception (MPFA statistics: equities ~5%, mixed ~4.5%).

Scenario C — conservative (1.3% p.a.): HK$1.33 million. Conservative funds have delivered ~1.2–1.5% annualised over ten years — and with August underlying inflation at 1.9% (Census and Statistics Department), the real return is negative.

The gap between A and C: HK$4.34 million — 12.6 times the average MPF balance of HK$343,242 (MPF Ratings, September), or 45 years of HK$8,000-a-month living expenses. Contributions were identical in all three; only the allocation differed.

Now the price of starting late: same Scenario A, but starting at 30 instead of 25 (35 years), ends at HK$3.88 million — HK$1.79 million less, a 46% smaller terminal balance. Waiting five years does not cost five years of contributions (HK$127,000); it costs those five years’ contributions compounding for the next 35. Time is the one asset a fresh starter holds that money cannot buy.

Three levers a fresh starter actually holds

Lever one: voluntary contributions, added early. eMPF’s consolidated data shows nearly half of employees aged 30–59 make voluntary contributions; among 40–49-year-olds who do, the voluntary pot averages about half their cohort’s average mandatory pot (Chairwoman’s blog) — equivalent to adding 5% of salary on top of the 10% mandatory. In our sandbox: an extra HK$1,060 a month of voluntary contributions adds HK$2.83 million over 40 years under Scenario A. For a median earner, tax-deductible voluntary contributions (TVC) save roughly HK$3,974 a year in salaries tax — a day-one return on the contribution.

Lever two: DIS de-risking only starts at 50. The statutory glide path (about 6.7 percentage points a year shifting from the Core Accumulation Fund into the Age 65 Plus Fund from age 50) is 25 years away for a 25-year-old — the growth-tilt window is at its longest right now. No need to worry about de-risking today, but know it exists: when it arrives, do not exit DIS to go all-in on equities “for one last push” — the sequence-risk maths on that move has been done before, and it is ugly.

Lever three: forward pricing — don’t chase the 10.3% by switching. MPF fund switches execute at unknown T+1/T+2 prices: today’s instruction settles at tomorrow’s or the day after’s NAV. Switching frequently to chase last year’s champion means buying and selling blind every time. A BCT programme disclosed a member who switched funds 110 times in half a year — that is not investing, it is paying an unknown-price tax.

This week’s action list

1. Log into eMPF and look at your actual fund allocation once. Your account may still sit in whatever HR ticked on your first day, or in DIS by default if you never gave instructions. Knowing what you own is step one of taking the helm.
2. Check the FER (fund expense ratio) of each fund you hold. The market average is 1.36%; the DIS cap is 0.85% (actual average ~0.77%). A 0.5-point fee gap in the same account can be hundreds of thousands over 30 years.
3. Set an annual review reminder — not a monthly one. MPF is a 40-year race; watching the 10.3%/-1.5% headlines every month only trains the urge to fiddle. Once a year, in your birthday month, is enough.

The MPFA’s old refrain is right: MPF is long-term investing; don’t buy high and sell low. But for a 25-year-old, the sharper version is this: you don’t need to beat the market — you just need not to lose to time. And the only way to lose to time is to start late.

Illustrative calculations assume a monthly contribution of HK$2,120 (10% mandatory on HK$21,200 monthly income), compounded monthly, before fee changes and cap adjustments. The 7.3% figure is the Core Accumulation Fund’s actual annualised net return from April 2017 to August 2026 (MPFA Chairwoman’s blog); 5% and 1.3% are illustrative assumptions. Past performance is not indicative of future results.
