What Is the Total Expense Ratio (TER)?
The total expense ratio (TER), known in Turkish as toplam gider oranı (TGO), is a measure that sums all the operating costs of holding an investment fund for a year into a single percentage. It expresses the total of management fee, custody, audit, brokerage commissions and registration/announcement costs as a ratio to the average fund size over the control period. Its value to an investor is this: when comparing two funds' returns, it shows at a glance how much of the return is 'eaten' by cost. 'Fon gider oranı' is a common alternative name for the same concept, and it is disclosed in the fund's information documents.
What does the total expense ratio cover?
The TER brings together all the fixed and variable costs incurred to run the fund day to day. The main items are:
| Cost item | What it pays for |
|---|---|
| Management fee | The service of the firm managing the portfolio (usually the largest item) |
| Custody fee | Safekeeping of fund assets at Takasbank |
| Audit fee | Independent audit |
| Brokerage commission | Trading execution costs |
| Registration & announcement | Legal notification and publication costs |
The largest of these is typically the management fee; the ratio is not a charitable cost but the price of having the portfolio managed professionally. A separate, success-based performance fee exists in some funds and is usually disclosed separately; the exact scope of the TER is defined in each fund's own information document. As a result, two funds of the same type can differ in expense ratio because of different management approaches.
Effect on return: a daily deduction from NAV
You do not pay the TER as a separate bill. The costs are deducted in small slices from the fund's total assets every trading day, which pulls the unit share value slightly lower that day. As a result, the return figures you see on TEFAS are the value after the TER has been deducted; that is, published returns are already net. So when you buy a fund you do not need to add a further commission on top: the cost is already inside the price. Lower cost means a higher net return for the same gross performance, and this gap matters because it compounds over the long run.
Maximum total expense ratio (the SPK cap)
In Turkey the TER is not left open-ended; it is subject to the maximum total expense ratio system in the annex of the SPK Communiqué III-52.1 (Principles Regarding Investment Funds). This system sets tiered upper limits by fund type:
- For the 'other funds' group the annual maximum expense ratio is 3.65%, corresponding to a daily deduction of roughly 10 per hundred thousand.
- For money market and short-term debt instrument funds the limit is lower, because their low-return, low-risk structure cannot bear a high cost.
These figures are legal upper limits, not current market fees; a fund's actual TER may sit well below the ceiling. The limit is monitored both daily and cumulatively over the control period. If realized costs exceed the limit at the end of the control period, the excess is returned to the fund through a correction mechanism, so the over-deduction flows back to investors. Funds' expense ratios and their compliance with the cap are disclosed to the public periodically via KAP, and these disclosures are subject to audit.
What the TER should not be confused with
- Withholding tax (stopaj): This is a tax on your gain when you sell the fund, not a fund operating expense. The TER is deducted daily from fund size; withholding is taken only at the moment of sale and from your profit. See the withholding tax page for detail.
- ETFs and trading costs: The broker commission you pay when buying and selling exchange-traded funds on the exchange, and the entry/exit commissions in some funds, are separate from the TER; they arise on your transaction, not inside the fund.
To see costs side by side, you can review different funds' expense and return data on category pages such as money market funds or in the comparison tool.
Frequently asked questions
is the total expense ratio deducted separately from the return?
No. The costs are deducted automatically from the fund's assets every day, lowering the unit share value. That is why the return figures published on TEFAS are already net of the total expense ratio; you make no separate payment.
are the total expense ratio and withholding tax the same thing?
No. The total expense ratio is the cost of running the fund and is deducted from fund size. Withholding tax is a tax taken from your gain when you sell the fund. One is a fund expense, the other is a tax.
is there an upper limit on the fund expense ratio in Turkey?
Yes. The SPK Communiqué III-52.1 sets a maximum total expense ratio by fund type. For the 'other funds' group the annual ceiling is 3.65%; for money market and short-term debt funds the limit is lower. These are legal caps, and the actual fee may be below them.
what is the largest item in the total expense ratio?
Usually the management fee, paid to the firm managing the portfolio. Alongside it, smaller items such as custody, audit, brokerage and registration/announcement costs are also included in the total expense ratio.
In short
The total expense ratio shows a fund's total annual holding cost as a single percentage, and because it is deducted from fund assets every day, published return figures already include this cost. In Turkey the SPK sets a maximum expense ratio by fund type, and any excess over the limit is returned to the fund. This ratio should not be confused with withholding tax, which is a separate tax, or with exchange trading commissions.
