Investment fees explained: How costs affect long-term returns

Key takeaways:

• Investment fees reduce the amount available to invest or remain invested, so even small annual costs can lower net returns over long periods through lost compounding.
• Types of investment fees include management fees, expense ratios, trading fees, load fees, advisory and account fees, performance fees, 12b-1 fees, and redemption or transfer fees.
• The long-term impact of fees can be meaningful: in the article’s simplified example, a USD 100,000 portfolio earning 8% before fees grows very differently over 30 years depending on annual costs.
• Ways to reduce investment fees include comparing low-cost products, checking for mutual fund load fees, reviewing trading costs and using fee comparison tools alongside risk and product features.
• Investment fees tax treatment varies by country, account type and personal circumstances, so costs and taxes are usually considered together when assessing net returns.

Investment fees are the costs you pay for accessing financial products and services. These fees cover everything from managing your portfolio to executing trades and maintaining your account. While they might seem small at first glance, their costs can add up over time, reducing net returns compared with returns before fees.

Every fee you pay reduces the money available to grow your portfolio. For example, a stock portfolio earning 8% annually before fees with 1% in fees would result in around a 7% return after fees (ignoring taxes and other costs). Over decades, this difference can translate into a large difference in final portfolio value, depending on the amount invested and time period.

Recognising these costs and understanding their impact can help investors make more informed choices about costs and trade-offs.

Types of investment fees

Fees can be applied in different ways depending on the product, platform and market. Understanding the different types of fees may help you identify costs that are relevant to your portfolio.

Management fees

Management fees compensate professionals who oversee your portfolio. Typically calculated as a percentage of assets under management (AUM)Ranges vary by region, product type and share class. For example, a 1% annual fee on a USD 100,000 portfolio would equal about USD 1,000 over a year, assuming the portfolio value stayed constant. Active management may seek to add value, but higher fees reduce net returns compared with a lower-fee version of the same return, all else equal. To outperform a benchmark after fees, an active strategy would need to deliver sufficient excess return to cover its total costs over the relevant period.

Expense ratios

Expense ratios are applied to mutual funds and ETFs to cover operational costs. These fees, expressed as a percentage of fund assets, often range from under 0.1% to over 1%, but ranges vary by region, product and share class. Even minor differences compound over time, making low-cost options more appealing for long-term portfolios. Generally speaking, passively managed funds (including some mutual funds and ETFs) can be less expensive than actively managed funds and ETFs) often have lower expense ratios than actively managed funds, although this is not always the case.

Trading fees

Trading fees are charges linked to buying or selling investments. A broker may charge a flat fee per trade, a percentage of the transaction, or other costs depending on the market and product. For frequent traders, these costs may add up over time. Platforms advertising zero-commission trading may still involve other costs, such as spreads, foreign exchange charges, custody fees or product-related costs. Reviewing the full fee schedule can help investors understand the total cost of trading rather than focusing only on commission.

Load fees

Load fees are sales charges tied to mutual funds. Front-end loads apply when you buy shares, while back-end loads are charged when selling. The level of these fees varies by fund, share class and market. These fees can reach up to 5.75%. Opting for no-load funds keeps your money working harder. No-load funds do not apply front-end or back-end sales loads, although they may still have other ongoing costs.

Advisory and account fees

Often associated with financial advisors, advisory fees cover portfolio management and planning services. These fees usually range from 0.25% to 1% annually, but they can vary by provider, service level, portfolio size and market. Some platforms may also charge account maintenance, custody or platform fees. Lower-cost platforms and robo-advisors may offer more limited or different services at lower cost.

Performance fees

Some funds charge performance fees when returns exceed a specified benchmark or hurdle rate. For example, a "2 and 20" structure charges 2% of assets annually and 20% of profits. These fees link manager compensation to performance, but they can also reduce investor returns when the performance-fee conditions are met. While these fees incentivise results, they can substantially reduce your net returns if they exceed the threshold amount. These funds are common in alternative investment assets such as hedge funds. Performance fees are often associated with alternative investment structures such as hedge funds and private equity funds, and can be controversial because incentives may influence risk-taking and time horizons, depending on the structure.

12b-1 fees

In the US, some mutual funds charge 12b-1 fees for distribution and, in some cases, shareholder services. These fees are paid from fund assets and form part of ongoing fund costs. They are more relevant to US mutual funds than to ETFs, so investors should check whether they apply to the specific fund and share class being reviewed.

Redemption and transfer fees

Redemption fees apply when you sell certain investments too quickly, discouraging short-term trading. Transfer fees, often charged when moving accounts between brokers, can vary by provider and market. Reviewing fee schedules before making changes may help avoid these costs.
