The Number That Decides What You Retire On: Understanding Effective Annual Cost
Almost nothing about a long-term investment is under your control. Not the returns, not the sequence in which they arrive, not the market you happen to retire into. One thing is: what you pay to hold it.
South Africa has a good tool for that, and hardly anyone asks for it. Under the ASISA Retail Standard on Effective Annual Cost, providers express what a product costs as a single annualised percentage — the EAC — built from four components and shown over four different holding periods.
The idea is that you can put two products side by side and compare one number instead of a brochure. It works, but only if you read the table the way it is built, and there are two traps in it that even careful people walk into.
The four components
Every charge is sorted into one of four buckets, calculated separately, and then added together to give the EAC for the product as a whole:
- Investment management charges — what it costs to run the underlying funds.
- Advice charges — what you pay an adviser, where the provider facilitates it.
- Administration charges — what it costs to run the product wrapper itself.
- Other charges — everything that does not fit the first three.
The investment management line is doing more work than it appears to. For a South African domiciled investment, it "would ordinarily include all costs and charges for all underlying investments", calculated under ASISA's separate standard on total expense ratios and transaction costs. So the fund's TER and its trading costs are already inside that number. You are not meant to add them again.
Trap one: a 0.0% advice line does not mean advice is free
This is the most common misreading, and the standard is explicit about why it happens.
Where the adviser charge is not facilitated by the provider, or where you have not engaged an adviser at all, "the advice charge is reflected as 0.0%" — and the provider must add a footnote explaining that no advice fee was supplied, so none could be included.
Read that carefully. A zero on the advice line can mean any of three quite different things: you genuinely pay nothing for advice; you pay an adviser directly, outside the product, so it does not appear here; or nobody told the provider what you pay.
Two products where one shows 0.0% advice and the other shows 0.6% are therefore not necessarily 0.6% apart. They may be identical in cost, with one of them simply not counting a fee you are still paying. Before you compare, confirm what the advice line represents in each case — and if you pay an adviser separately, add that in yourself.
Trap two: the one-year column is inflated by design
Here is the thing almost nobody explains, stated plainly in the standard's own consumer-facing note:
"Over the longer term, the reduction in return on your investment reflected in these numbers and the actual charges are similar. Over the shorter term, the reduction in return is higher than the actual charge. After 1 year, the reduction in return may be as high as double the actual charge incurred."
The EAC is a reduction-in-yield measure, not a simple fee total. Over a short period, front-loaded costs and exit charges get spread across very little time, so the annualised figure overstates what you are actually being charged. The standard says it may be as much as double.
The practical consequence is the opposite of most people's instinct. The one-year column is the one you should trust least for comparison. If you are investing for twenty years, the column that matters is term to maturity — and that is the one where the numbers converge on the real charge.
Why the "other" line jumps around
If you look at an EAC table and see the "other" component swing wildly between columns, or even go negative, that is the design working rather than an error.
Termination charges, exit penalties, loyalty bonuses and similar structures are deliberately excluded from the administration component. They land in "other" instead, and they are counted on the assumption that you terminate at the end of each period shown. So a product with a heavy early-exit penalty shows a large "other" figure at one year that shrinks as the penalty falls away, and a product with a loyalty bonus payable at maturity can show a negative number in the final column.
A negative "other" is not free money. It is a payment you only receive if you stay to the end — which is exactly the behaviour the structure is designed to buy.
What the fees actually cost you
Percentages this small do not feel dangerous, which is the problem. Here is what they do to a portfolio, assuming a 9% gross return a year.
The figures below are the share of your final pot consumed by fees — for a single amount left to grow, and for level monthly contributions, which is how most people actually save:
| Annual fee | 20 years (lump sum) | 30 years (lump sum) | 20 years (monthly) | 30 years (monthly) |
|---|---|---|---|---|
| 0.5% | 8.8% | 12.9% | 5.6% | 9.1% |
| 1.0% | 16.8% | 24.2% | 10.9% | 17.2% |
| 2.0% | 31.0% | 42.6% | 20.6% | 31.3% |
| 2.9% | 41.7% | 55.5% | 28.2% | 41.7% |
In rand: R2,000 a month for 30 years at 9% gross grows to about R3,404,000 with no fees at all. At 1.0% a year you end with roughly R2,817,000. At 2.9% — the figure used in the standard's own worked example — you end with about R1,985,000.
The gap between those last two is R832,000, on identical contributions and identical markets. That is the entire case for asking the question.
The claim that is overstated
You will often read that a 1% fee costs you a third of your retirement savings. That number is real, but it belongs to a specific and unusual case: a single amount, left untouched, for forty years. There the figure is 30.8%.
For the ordinary case — contributions paid in monthly over thirty years — a 1% fee costs 17.2% of the final pot. Still a very large number, and worth acting on. But roughly half what the familiar version claims, because money contributed in year twenty-eight has only been exposed to the fee for two years.
It is worth being accurate about this. The honest figure is more than persuasive enough, and quoting the inflated one invites the reasonable suspicion that the rest is exaggerated too.
What to actually do
- Ask for the EAC in writing, for the product you hold and any product being recommended to you. It is a disclosure standard that ASISA members adhere to; you do not need to justify the request.
- Compare the term column, not the one-year column, if you are investing for the long term.
- Establish what the advice line means in each quote before treating a difference as real, and add in anything you pay an adviser separately.
- Check whether "other" contains an exit penalty. If it does, you are looking at a product that charges you for leaving — which matters most precisely when you discover you want to.
- Separate the decision to pay for advice from the decision to pay without knowing. Good advice is worth paying for. The point is to see the number, not to assume it should be zero.
Low cost is not the same as good. A cheap product in the wrong asset allocation, or one you abandon in a downturn, will beat nothing. But cost is the only input here that is known in advance and guaranteed to occur, and it compounds in the same relentless way returns do — just in the wrong direction.

Frequently asked questions
What is the Effective Annual Cost? A single annualised percentage showing the estimated impact of charges on your investment return, built from four components — investment management, advice, administration and other — which are calculated separately and added together.
Over what periods is it shown? Four: the next 1 year, the next 3 years, the next 5 years, and term to maturity.
Which column should I compare? The one closest to how long you will actually hold the product. For long-term investing that is term to maturity. The standard itself notes that after one year the reduction in return "may be as high as double the actual charge incurred".
Does a 0.0% advice charge mean I am not paying for advice? Not necessarily. It is shown as 0.0% where the adviser charge is not facilitated by the provider or where you have not engaged an adviser, with a footnote to that effect. You may still be paying an adviser directly.
Why does the "other" line change so much between columns, or go negative? Termination charges, exit penalties and loyalty bonuses are excluded from administration and placed in "other", assessed on the assumption you exit at the end of each period. A loyalty bonus at maturity can make the final figure negative.
Is the fund's TER included, or must I add it? For a South African domiciled investment the investment management component ordinarily already includes the costs and charges of the underlying investments, calculated under ASISA's TER and transaction cost standard. Do not double count it.
How much does 1% a year really cost me? On monthly contributions over 30 years at a 9% gross return, about 17.2% of your final pot. On a single amount left for 40 years it is about 30.8% — which is where the widely quoted "a third of your savings" comes from.
Is the cheapest product the best one? No. Cost is the input you can know in advance and control, which makes it the right place to start — but asset allocation, suitability and whether you stay invested through a downturn all matter more to the outcome.
