How this calculator works

What it does
Compare how two ETF expense ratios can affect long-term investment growth and the ending value of regular contributions.
Inputs used
The estimate uses investment amount, monthly contribution, etf a expense ratio (%), etf b expense ratio (%), expected annual return (%), and number of years.
Calculation approach
The calculator applies the relationships defined for the etf fee drag calculator to those inputs and updates etf a ending balance, etf b ending balance, difference between etfs, and higher-cost etf drag.
How to read the result
Treat the result as a scenario based on the values entered. Compare a few reasonable inputs and consider costs, taxes, timing, or risks that the calculator does not include.

How to Use This Calculator

  1. Enter Investment amount and Monthly contribution using values that match the scenario you want to evaluate.
  2. Enter ETF A expense ratio (%) and ETF B expense ratio (%) using values that match the scenario you want to evaluate.
  3. Enter Expected annual return (%) and Number of years using values that match the scenario you want to evaluate.
  4. Review the assumptions for the etf fee drag calculator, especially rates, time periods, and optional amounts.
  5. Select Calculate to update the results, then adjust one input at a time to compare scenarios.

Understanding the Results

ETF A ending balance
The estimated value at the end of the selected period after applying the entered contributions, rates, and timing assumptions.
ETF B ending balance
The estimated value at the end of the selected period after applying the entered contributions, rates, and timing assumptions.
Difference between ETFs
The difference between the current position and the calculated target or comparison value.
Higher-cost ETF drag
The higher-cost etf drag estimated by the ETF Fee Drag Calculator using investment amount, monthly contribution, and etf a expense ratio (%) and the other values entered.

Example inputs

Investment amount
$100,000
Monthly contribution
$500
ETF A expense ratio (%)
0.03%
ETF B expense ratio (%)
0.75%
Expected annual return (%)
7%

Example results

ETF A ending balance
$1,410,806.57
ETF B ending balance
$1,175,876.61
Difference between ETFs
$234,929.96
Higher-cost ETF drag
$234,929.96

With these illustrative inputs, the etf a ending balance is $1,410,806.57. The result shows how the example assumptions interact and is not a prediction of future performance.

Frequently asked questions

What is ETF fee drag?

ETF fee drag is the reduction in long-term portfolio value caused by expense ratios. It includes both fees paid and the compound growth those dollars no longer earn.

How does an ETF expense ratio work?

An expense ratio is an annual percentage deducted from fund assets to cover operating costs. It reduces the investment return retained by shareholders.

Why can a small fee difference matter?

A small annual difference can compound over decades, affecting the growth of the starting investment and every monthly contribution.

Does the lower-cost ETF always perform better?

Not necessarily. This calculator assumes both ETFs earn the same return before fees. Actual funds can differ in holdings, tracking, taxes, risk, and performance.

What assumptions does this comparison use?

It assumes constant expense ratios, monthly compounding, contributions at the end of each month, and the same constant pre-fee return for both ETFs.

What does the ETF Fee Drag Calculator calculate?

Compare how two ETF expense ratios can affect long-term investment growth and the ending value of regular contributions. The result is based only on the inputs and assumptions shown on the page.

How should I interpret the higher-cost etf drag from the ETF Fee Drag Calculator?

Use it as an estimate for the scenario entered, not as a guarantee or personal recommendation. Test changes to investment amount, monthly contribution, and etf a expense ratio (%) to see which assumptions have the greatest effect.
