TER (Total Expense Ratio)

What TER measures

The total expense ratio (TER) is a standardised metric expressing an investment fund's ongoing annual running costs as a percentage of average fund assets. It was originally established by the US Securities and Exchange Commission as the "expense ratio", and was made a mandatory disclosure in Europe under the UCITS Directive and the PRIIPs Regulation, where it has to be shown in the Key Information Document (KID).

The TER bundles together: the management fee (the asset manager's fee, often 70% to 90% of the total cost block), the custody and depositary fee, index licensing fees (paid to MSCI, S&P Dow Jones or Bloomberg, for example), audit and publication costs, and regulatory levies.

Crucially, the TER is not the full cost an investor bears. It excludes a fund's internal transaction costs (spreads, broker fees on rebalancing), performance fees on active funds, taxes on income, and the trading costs of buying the fund itself (front-end load, exchange spread, broker order fees).

Typical ranges in 2025

TERs vary significantly by fund type:

• Passive ETFs on large standard indices (MSCI World, S&P 500, MSCI Emerging Markets): typically 0.07% to 0.25% per year. The Vanguard FTSE All-World UCITS ETF charges 0.22%, the iShares Core S&P 500 0.07%.
• Passive ETFs on niche indices (thematic, factor, ESG, small caps): typically 0.25% to 0.75%.
• Actively managed equity funds: typically 1.2% to 2.0%, often plus a 15% to 20% performance fee.
• Mixed and fund-of-funds: typically 1.5% to 2.5% because of layered cost structures.

Since 2023, EU PRIIPs KIDs have additionally disclosed the more comprehensive "ongoing charges" figure, which includes implicit transaction costs and on active funds typically sits 0.1 to 0.5 percentage points above the pure TER. Methodologically almost identical is the Ongoing Charges Figure (OCF), which has been the European headline metric since MiFID II and PRIIPs; it diverges from the TER only slightly in fund-of-funds structures, because it incorporates a pro-rata share of the costs of underlying target funds. In everyday usage TER and OCF are treated as synonyms.

In numbers

An investor puts €50,000 into an actively managed equity fund with a TER of 1.75% as a lump sum. Over ten years at a gross return of 7% per year, the running costs amount to about €9,300 of forgone wealth versus a comparable ETF charging 0.20%. Over a 30-year horizon, compounding stretches that gap to roughly €75,000 — a terminal value of about €232,000 instead of €307,000. That mechanic is the economic heart of the active-vs-passive debate. Empirically — see S&P's annual SPIVA studies — very few active funds manage to beat their benchmark consistently after costs.

Related concepts

To read the TER correctly, look at it together with adjacent concepts: the OCF as Europe's equivalent metric, the tracking difference as the real-world return gap between an ETF and its index, the front-end load on traditional mutual funds, and the performance fee as the success-linked surcharge on active strategies. Only taken together do they give a realistic picture of what a fund investment actually costs.
