What do investment fees really cost over 20 or 30 years?
Far more than the percentage suggests. A fee of 1% a year sounds like 1% — but it is charged on the whole pot, every year, and every rand it takes stops compounding for you from that day on.
Over a 30-year saving life, one extra percentage point of annual fees removes roughly a fifth of the final pot. Over 40 years, roughly a quarter. The percentage is small; the compounding is not.
Why 1% is not 1%
Fees are charged on your balance, not your growth. In a year the market returns 10%, a 1% fee takes a tenth of your entire return. In a flat year it takes the fee anyway. And the rand it took this year would have earned returns next year, and the year after — the loss compounds exactly the way growth does, just against you.
The same savings, four fee levels
R2,000 a month, invested for 30 years, growing at 10% a year before fees. The only thing that changes below is the annual fee:
- No fees (the benchmark): about R4.52 million
- 1% a year: about R3.66 million — 19% less
- 2% a year: about R2.98 million — 34% less
- 3% a year: about R2.44 million — 46% less, nearly half the pot gone
Stretch it to 40 years and the same 1% difference costs 26% of the final pot — on these numbers, a gap of about R3.3 million. Nobody writes a cheque for that amount; it leaves a few rands at a time, which is why almost nobody notices.
What the fees actually are
South African investors usually pay several layers at once, and the layers live in different documents:
- Fund management — the TER (total expense ratio) of each fund, covering the manager and fund running costs
- Administration — the platform or LISP that hosts the investment
- Advice — an initial and/or ongoing fee where a financial planner is engaged
- Other costs — trading costs inside the fund, performance fees where they apply
To stop the layers hiding from each other, South Africa has a disclosure standard: the EAC (effective annual cost), which every provider must show on request as one comparable number split into those four parts. It is the single most useful number on any fund document — and it appears on the fund fact sheet (the minimum disclosure document) or on request from the provider.
The honest version: fees buy things
This is not a story about all fees being bad. Fund management is real work; platforms are real infrastructure; and good financial advice — tax structuring, behaviour in a crash, estate planning — can be worth multiples of what it costs. Some of the most expensive investing mistakes are made by people saving 1% in fees.
The point is narrower: the cost is large, compounding, and mostly invisible — so it should be known, not guessed. What is being paid, what is received for it, and what the same investment costs elsewhere are three questions with factual answers.
Finding your own number
- Ask any provider for the EAC of each product — disclosure of it is a South African standard, not a favour
- Read the TER on each fund's minimum disclosure document (the fact sheet)
- Add the layers: fund + platform + advice = the real annual cost
- Compare against the pot, not the gain — that is how the fee is actually charged
Terms used on this page
- EAC (effective annual cost)
- South Africa’s standard for disclosing what an investment really costs: one comparable yearly percentage, split into fund management, administration, advice and other costs.
- TER (total expense ratio)
- The yearly running cost of a fund — management and operating costs — shown as a percentage of your investment on the fund’s fact sheet.
- compounding
- Growth on growth: returns earn their own returns. It is why time in the market matters more than the size of any single deposit.
