ETF fee drag in plain English
An ETF expense ratio reduces fund returns by covering operating costs. If two funds track similar exposures but one costs more, the higher fee can create a drag on long-term results.
The drag compounds because each dollar paid in costs is no longer invested. Over decades, that lost growth can become more noticeable.
When to use the ETF Fee Drag Calculator
Use the ETF Fee Drag Calculator when comparing two funds with different expense ratios. Enter starting balance, contributions, assumed return, time horizon, and both fee levels to estimate the difference.
The calculator is most useful when funds are otherwise similar. If two ETFs have different exposures, tax behavior, liquidity, or risk, the fee comparison is only one part of the decision.
What fee drag leaves out
Expense ratio comparisons do not capture tracking error, bid-ask spreads, taxes, securities lending, fund closure risk, or how well the ETF matches the investor’s desired asset allocation.
Use the fee result as a screening tool, then review the broader investment fit.
