What is an Expense Ratio?

An expense ratio is a metric used to assess the costs associated with investing in mutual funds and exchange-traded funds (ETFs). These fees, which are calculated annually as a percentage of the fund’s total assets, help fund the operating costs associated with running a mutual fund or ETF. Knowing the expense ratio of the funds you’re investing in can help you make decisions on where to put your money.

How is an Expense Ratio Calculated?

An expense ratio is calculated by taking a fund’s annual expenses and dividing it by its average assets under management. This will generate an expense ratio in the form of a percentage. For example, if the fund has total annual operating costs of $100,000 and average assets of $10 million, the expense ratio would be 1% ($100,000 / $10 million = 0.01 = 1%).

Benefits of Low Expense Ratios

Low expense ratios are key to turning a profit for investors. A fund with a higher expense ratio will have lower returns, since a large portion of the assets are being taken away in fees. That’s why it’s important to do your research and look for funds with low expense ratios when making investment decisions. If you can find a fund with an expense ratio of 0.1%, or 1/10th of the expense ratio in the aforementioned example, you’ll have more money to invest instead of giving it away to expensive fees.

Currency Misalignment and Financial Instability

In the 1980s and 1990s, financial instability in emerging markets (EMEs) was largely due to insufficient flexibility in the exchange rate. Poorly pegged exchange rates left these markets exposed to rapid currency misalignment and financial markets experienced larger losses than expected due to currency devaluation. This is why it is imperative to choose an ETF with a low expense ratio; if the fund takes a hit due to currency move, you want to at least have the lowest cost to mitigate losses.


As an investor, it’s important to understand the implications of all investments your broker or investment fund managers make on your behalf. One such important factor is the ‘Expense Ratio’, which is a measure of what it costs to internalize your investments. This ratio takes into account various aspects like operating costs, trading commissions, overhead, and more to calculate the cost of investing in a fund. The lower this number is, the better it is for you as it means you are paying less for the services provided.

In essence, the expense ratio is a way for investors to measure the costs associated with owning and operating a mutual fund. As such, knowing the expense ratio of a fund can help an investor assess how expensive the fund is relative to similar funds. This can provide important context for a particular investment decision. Additionally, understanding the expense ratio can help investors decide if certain funds are worth their cost.


The expense ratio of a fund is calculated by adding up all operating costs plus trading commissions, then dividing that number by the total amount of money in the fund. The percentage this figure represents is the expense ratio. For example, if a fund’s expense ratio is 0.5%, then investors will pay a fee of $5 for every $1000 invested in that fund. It is important to take into account annual fees and other associated costs when calculating an expense ratio.

The cost associated with an expense ratio can vary from fund to fund. Generally, index funds have lower expense ratios than actively-managed funds. A traditional index fund, in particular, has an average expense ratio of 0.3%, whereas an actively-managed fund usually charges a slightly higher expense ratio because of the higher cost associated with trading and research.


Although expense ratios are sometimes unavoidable when investing, there are ways to reduce the impact of them. For instance, an investor should look for funds with lower expense ratios, such as those that are passively managed. Moreover, they should shop around and compare fees from different fund managers before settling on one. Doing so could potentially result in a better return on investment and less out-of-pocket expenses.

For those who want to further reduce their expense ratio costs, they can opt for investing in exchange-traded funds (ETFs). ETFs are typically offered with much lower expense ratios since they are constructed using a portfolio of stocks and bonds. This means they do not require the same kind of active management as actively-managed funds, thus leading to lower fees.

Overall, it is important to remember that expense ratios matter when it comes to investing. Hence, investors should understand what expense ratios are, how to calculate them, and how to minimize them for better returns. Doing so can make a huge difference in the amount of money an investor can earn from their investments.
