Understanding ETF Fees and Fee Drag

ETF fees matter because they reduce the return that remains for the investor. Even small annual cost differences can become meaningful over long time periods.

One common ETF cost is the total expense ratio, often called the TER or ongoing charge. This is the fund-level cost charged by the ETF provider. Investors may also face broker fees, platform custody fees, foreign exchange charges, spreads and transaction costs.

Fee drag refers to the long-term effect of these costs on portfolio growth. A fee that looks small in one year can have a larger effect over decades because the money paid in fees no longer remains invested and cannot compound.

For example, a portfolio with lower total costs does not automatically perform better, but it has a lower hurdle to overcome. Higher costs require stronger gross returns just to reach the same net outcome.

ETF Compass includes fee assumptions so users can see how costs may affect projected long-term values. The calculator does not judge whether a fee is acceptable. It simply shows the possible impact based on the user's inputs.
