What Every ETF Investor Pays, Seen and Unseen

ETF fees reduce your returns every single year, and because that money is no longer invested, you also lose everything it would have earned. The main fee is the expense ratio, charged as a percentage of your investment, but bid-ask spreads, premiums, trading costs inside the fund and taxes all affect what you keep. Over decades, the gap between a low-cost and a high-cost ETF can run into tens or even hundreds of thousands of dollars.

The difference looks tiny on paper. A fee of 0.03% and a fee of 1% are both less than one percent. But on $100,000 invested for 30 years, that gap could cost you more than $180,000, as the example below shows.

The most expensive investment mistake may be the one you never realised you were making. FRC’s three ETF programmes, ETF Investing for Beginners, ETF Investing Strategies and Advanced ETF Investing, show you how to read an ETF’s true costs, compare funds properly and stop fees quietly eating into your wealth. They are written in plain English, need no finance degree, and are open to everyone.

This guide is part of FRC’s complete step-by-step guide to investing in ETFs. It explains every cost an ETF investor pays, how to find each one and how to tell when a higher fee might be worth it.

How an ETF Fee Is Taken Without You Ever Seeing a Bill

The expense ratio is the annual fee a fund charges to cover management, administration, index licensing and other running costs. It is shown as a percentage of the money you have invested. A 0.20% expense ratio means $20 a year for every $10,000 you hold. Outside the US, you may see the same cost called the total expense ratio (TER), the ongoing charge or, in Canada, the management expense ratio (MER).

Fees are often quoted in basis points, where one basis point is 0.01%, so a 0.20% fee is 20 basis points. The fund calculates its expense ratio by dividing its total operating costs by its total assets.

You never receive an invoice. The annual fee is divided across the days of the year, accrues daily and is deducted from the fund’s assets in tiny increments, which reduces the fund’s net asset value. The performance figures you see are already after fees, so the cost is easy to forget.

That invisibility is the problem. Because nothing leaves your account, many investors have no idea what they pay, and a fund charging ten or twenty times more than a comparable one can sit in a portfolio for years unnoticed.

The Real Cost of Fees Over Time

Fees compound in the same way returns do, only in reverse. Every dollar taken in fees is a dollar that no longer earns returns for you, year after year. Take $100,000 invested for 30 years, with the investments earning 7% a year before fees.

At a 0.03% expense ratio, the investment grows to about $754,849. At 0.20%, it reaches about $719,677. At 0.50%, it reaches about $661,437. At 1.00%, it reaches about $574,349, roughly $180,500 less than the lowest-cost fund.

Regular investors see the same effect. Investing $500 a month for 30 years, a total of $180,000, grows to about $606,387 at 0.03% but about $502,258 at 1.00%. That is a difference of more than $104,000, from a fee gap that looks like less than one percentage point.

These figures are illustrative and assume a steady return, which real markets never deliver. But the principle holds in every market: the higher the fee, the less of the market’s return reaches you. FRC’s guide to how compound interest builds wealth in ETFs explains the compounding that fees work against.

Don’t start investing and then start learning how investing works. ETF Investing for Beginners explains expense ratios, compounding and the real cost of ownership before you commit a single dollar.

How to Calculate What an Expense Ratio Costs You

The annual cost is simple to work out: multiply the value of your investment by the expense ratio. On $25,000 in an ETF charging 0.15%, that is $25,000 × 0.0015, or $37.50 a year. As your investment grows, the dollar cost grows with it.

The long-term cost takes one more step. Subtract the fee from the return you expect, then compound the result over your holding period, and compare it with the same calculation for a cheaper fund. The gap between the two figures is what the higher fee costs you, including the growth you lose on every dollar paid.

Online expense ratio calculators, including the free FINRA Fund Analyzer, do this for you. Running your own funds through one is one of the quickest ways to see what you really pay.

What Is a Good Expense Ratio? A Guide by Fund Type

Broad index ETFs tracking major US stock markets are among the cheapest investments ever offered to ordinary investors. For S&P 500 and total US market funds, around 0.03% to 0.09% a year is typical, which is just $3 to $9 a year on $10,000.

Broad international funds investing in developed markets often charge around 0.05% to 0.20%, while emerging-market funds can run higher. Core bond ETFs tracking the broad investment-grade bond market are often in the 0.03% to 0.15% range.

Sector, thematic and smart beta ETFs commonly charge around 0.20% to 0.75%, and actively managed ETFs often 0.50% to 0.75% or more. Leveraged, inverse, commodity and option-income ETFs can charge from around 0.50% to more than 1.50%, before their other costs.

As a rough rule of thumb, a plain index fund tracking a major market should cost well under 0.15% a year. Anything approaching 0.50% to 1% for a basic index fund is expensive, unless there is a clear reason for the extra cost.

Some fund providers have gone further. A small number of index funds and ETFs charge no expense ratio at all, as FRC’s guide to Fidelity’s index funds explains. Zero-fee funds can come with conditions, such as only being available through one broker. And a zero expense ratio removes only one cost: spreads, trading costs and taxes still apply.

The Costs You Pay When You Buy and Sell

The expense ratio is not the only cost. Every time you trade an ETF, you pay the bid-ask spread, the gap between the highest price a buyer will pay and the lowest price a seller will accept. You buy at the higher ask price and sell at the lower bid price.

For the largest ETFs, the spread is often just a cent or two per share, around 0.01% of the price on a $100 share. For smaller, thinly traded or specialist ETFs, it can be much wider, sometimes costing more in a single trade than a year of expense ratio. If you trade often, spreads can easily become your biggest cost.

That can change which fund is really cheapest. A fund with a 0.02% expense ratio but a 0.10% spread can cost more than a fund with a 0.06% expense ratio and a 0.01% spread, if you trade it regularly or buy in small monthly amounts. For a long-term holder who rarely trades, the expense ratio matters more; for a frequent trader, the spread often does.

Most major US brokers no longer charge commissions on online ETF trades, but some still do for certain accounts, funds or phone orders. Check your broker’s fee schedule before assuming a trade is free, including any account, transfer or inactivity charges.

Premiums and Discounts: Paying More Than the Fund Is Worth

An ETF’s market price usually stays very close to the value of its holdings, its net asset value. But during volatile markets, or for funds holding hard-to-trade assets such as some bonds or international stocks, the price can move above or below that value.

Buy at a premium and you pay more than the underlying holdings are worth. Sell at a discount and you receive less. These gaps are usually small, but they can widen sharply during market stress, exactly when many investors rush to sell.

Using limit orders rather than market orders helps control the price you pay. Avoiding trades in the first and last few minutes of the trading day, when spreads are often wider, can also help.

Understand the risks, costs and mechanics before making your investment decisions. ETF Investing Strategies teaches you how to judge an ETF’s liquidity, spreads and premiums, so you trade at a fair price every time.

How Fees Reduce the Income You Receive

Fees matter just as much for income investors. An ETF’s expenses are paid out of the income its holdings generate, so the dividends and interest you receive are what is left after the fund has taken its fee.

Take two funds holding similar bonds that earn 4.5% a year in interest. One charges 0.05% and the other 0.60%. Before any other costs, the first can pass on about 4.45% to investors, while the second passes on about 3.90%.

On a $200,000 income portfolio, that gap is about $1,100 a year of income, every year, for as long as you hold the fund. For someone living off their portfolio, a high fee is a permanent cut in their pay. FRC’s guide on why a high ETF dividend yield can be misleading covers the other factors to check before chasing income.

The Hidden Costs Inside the Fund

Some costs never appear in the expense ratio. When an ETF buys and sells holdings, it pays its own trading costs, including spreads and commissions in the underlying market. These costs reduce the fund’s returns but are not included in the headline fee.

Funds with high turnover, those that replace a large share of their holdings each year, tend to carry higher hidden trading costs. A fund’s turnover ratio, shown in its prospectus, gives you a guide.

Some costs work in your favour. Many ETFs lend out their holdings through securities lending and keep part of the income, which can partly offset the expense ratio. That is one reason a fund’s real performance can differ from what its fee alone would suggest.

Tracking Difference: The Truest Measure of Cost

The best way to see what an ETF really costs is to compare its return with the index it tracks. That gap is called tracking difference. If an index returns 10% in a year and the ETF returns 9.95%, the tracking difference is 0.05%.

Tracking difference captures the expense ratio, hidden trading costs, securities lending income and how well the fund follows its index. It also reflects cash drag, the effect of holding uninvested cash such as dividends waiting to be paid out, and sampling, where a fund holds only some of an index’s securities rather than all of them. Two ETFs with the same expense ratio can have quite different tracking differences.

Tracking difference is not the same as tracking error, although the terms are often confused. Tracking error measures how much that gap varies from day to day or month to month. A fund can have a small, steady tracking difference and low tracking error, which is what most investors want.

Look at tracking difference over several years, not just one. A fund that consistently trails its index by more than its expense ratio may have hidden costs or a weaker tracking process.

Roll Costs and Daily Resets in Commodity and Leveraged ETFs

Commodity ETFs that hold futures contracts face a cost most investors never see. As each contract nears expiry, the fund must sell it and buy a later one, a process called rolling. When later contracts cost more than nearer ones, a market condition called contango, the fund repeatedly sells low and buys high, which can drag returns well below the spot price of the commodity.

Leveraged and inverse ETFs reset their exposure every day. Over longer periods, especially in volatile markets, that daily reset can cause returns to drift far from the multiple of the index you might expect. Add their higher expense ratios and financing costs, and these funds are built for short-term use, not long-term holding.

Tax Drag and Foreign Withholding Taxes

Tax is a cost too. Capital gains distributions and income taxed at ordinary rates reduce what you keep in a taxable account, even if the fund’s headline fee is low. A fund that distributes gains regularly can cost you more after tax than a slightly more expensive but more tax-efficient alternative.

International ETFs face an extra layer. Many countries deduct withholding tax from the dividends the fund receives, which lowers the fund’s return before you see it. In some cases you can claim a foreign tax credit, but the cost is real and is not part of the expense ratio.

Fees on Top of the ETF: Advisers, Platforms and Wrappers

The fund’s fees may not be the only ones you pay. If you use a financial adviser or robo-adviser, you may pay an advisory fee, often charged as a percentage of the assets they manage. A 1% advisory fee on top of a 0.10% ETF means total costs of 1.10% a year.

Some platforms and model portfolios add their own charges, and funds that invest in other funds can include acquired fund fees, the costs of the underlying funds. These appear in the prospectus fee table and are easy to miss.

Professional advice can be valuable, and a good adviser may earn their fee many times over. The point is to know the total you pay, so you can judge whether you are getting value for it.

ETF Fees vs Mutual Fund Fees

ETFs are usually cheaper to own than comparable mutual funds. Many mutual funds charge sales loads, such as a front-end load taken from your investment when you buy, and some charge 12b-1 marketing and distribution fees each year. ETFs do not charge sales loads.

ETFs also tend to be more tax-efficient, which reduces another cost: the tax paid on capital gains distributions. FRC’s guide to how ETFs are taxed in the United States explains why.

Low-cost index mutual funds can be just as cheap as ETFs, and some charge nothing at all. The structure matters less than the actual fees, so always compare the numbers rather than assuming one type is cheaper.

Is the Cheapest ETF Always the Best?

Not always. Cost is one of the most reliable predictors of long-term returns among funds tracking the same market, so when two ETFs follow the same index, the cheaper one usually comes out ahead.

But a lower fee does not make a fund suitable for you. An ETF tracking a different index, holding different assets or taking different risks cannot be judged on cost alone. A cheap fund that does not fit your goals is still the wrong fund.

The right approach is to decide what you want to own first, then find the lowest-cost, well-run way to own it. FRC’s guide to how to choose an ETF walks through every factor to weigh alongside the fee.

When a Higher Fee Can Make Sense

Some strategies simply cost more to run. Funds that hold international or emerging-market stocks, harder-to-trade bonds or options strategies carry higher operating costs, and no ultra-cheap version may exist.

Active ETFs charge more because they pay managers to try to beat a benchmark. Some do, many do not, and past success does not guarantee future results. If you pay for active management, check whether the fund has delivered after fees over a long period.

The question to ask is not whether a fund is expensive, but whether you are getting something for the extra cost that you could not get more cheaply elsewhere.

How to Find an ETF’s Fees

Every ETF must disclose its fees in its prospectus, in a standard fee table near the front. It shows the management fee, other expenses, any acquired fund fees, the total annual operating expenses and any fee waivers, along with an example of costs over one, three, five and ten years.

The fund’s fact sheet and website also show the expense ratio, and many providers publish premium, discount and spread data. FINRA’s Fund Analyzer, a free online tool, lets you compare the costs of different funds over time.

Check for fee waivers. Some funds temporarily reduce their fee, and the waiver may end. The prospectus shows both the gross expense ratio and the net figure after waivers, so you can see what you could pay if a waiver expires.

Seven Ways to Cut the Cost of Investing in ETFs

First, compare expense ratios between funds tracking the same index before you buy. Second, check tracking difference over several years, not just the headline fee.

Third, favour liquid ETFs with narrow spreads, especially if you trade often. Fourth, use limit orders and avoid trading right at the open and close.

Fifth, trade less. Every unnecessary trade adds spread costs and, in a taxable account, potential tax. Sixth, check your broker’s commissions and any account or platform fees.

Seventh, add up every layer of cost, including adviser fees, and review them at least once a year. Knowing exactly what you pay is the first step to paying less. FRC’s guide to 25 ways to cut the cost of investing in ETFs goes through every saving in detail.

Don’t let ignorance become your biggest investment expense. Advanced ETF Investing goes deeper into total cost of ownership, tracking difference and portfolio efficiency, so more of every year’s return stays with you.

Common Questions

How do ETF fees affect returns? ETF fees reduce your return every year, and because the money paid in fees is no longer invested, you also lose the future growth it would have earned. Over decades, even a small difference in fees can add up to a large difference in wealth.

What is an expense ratio in an ETF, with an example? It is the fund’s annual fee as a percentage of your investment. On $10,000 in an ETF with a 0.10% expense ratio, you pay about $10 a year, deducted from the fund’s value rather than billed to you.

What is a good expense ratio for an ETF? For broad US stock index ETFs, many charge less than 0.10% a year. Specialist, international and active ETFs usually cost more, so compare each fund with others following a similar strategy.

When are ETF fees deducted? The expense ratio is quoted as an annual figure, but it accrues daily and is deducted from the fund’s assets in small amounts. You never receive a bill, and the cost is already reflected in the fund’s price and returns.

Do you pay ETF fees if the fund loses money? Yes. The expense ratio is charged on the value of your investment whether the fund rises or falls, so fees add to losses in a bad year.

Do all ETFs have expense ratios? Almost all do. A small number of funds charge no expense ratio, often as a promotion or only through one broker, but every ETF still carries trading costs such as the bid-ask spread.

What expense ratio is too high? It depends on the fund type. For a plain index fund tracking a major market, anything approaching 0.50% or more is expensive when similar funds charge under 0.10%. For specialist or active funds, compare with similar funds and ask what you get for the extra cost.

What is the 70/30 rule for ETFs? It usually refers to a portfolio of 70% stock ETFs and 30% bond ETFs, a slightly more growth-focused mix than the traditional 60/40 portfolio. Some investors also use it to describe splitting stock investments 70% to developed markets and 30% to emerging markets. Building it from low-cost broad funds keeps the overall cost low.

Is it better to own one ETF or several? One broad, low-cost fund can be enough, and every extra fund adds its own fee. Owning several overlapping funds can mean paying more for the same exposure. FRC’s guide on how many ETFs you should own explains how many you really need.

Are ETFs cheaper than mutual funds? Usually. ETFs do not charge sales loads, often have lower expense ratios and tend to be more tax-efficient. But some low-cost index mutual funds are just as cheap, so compare the actual fees.

What hidden fees do ETFs have? Beyond the expense ratio, you can pay bid-ask spreads, premiums over net asset value, trading costs inside the fund, roll costs, tax drag, broker commissions and any adviser fees. Tracking difference is the best guide to the fund’s all-in cost.

Your Portfolio Deserves an Educated Investor

Fees are one of the few parts of investing you can control. You cannot choose what the market returns, but you can choose how much of that return you give away.

Your hard-earned money represents years of work. Give it the respect it deserves. FRC’s three progressive ETF programmes take you from understanding what an ETF costs, through comparing funds and trading efficiently, to managing a portfolio built for long-term value. FRC’s programmes and memberships are open to everyone, whether you are investing $500 or $500,000.

Invest in understanding the market before investing in the market itself. The less you pay, the more you keep.
