Managed Fund vs ETF Cost Calculator

How to Use This Tool

Follow these steps to generate an accurate cost comparison between managed funds and ETFs:

1. Enter your initial investment amount (the lump sum you plan to invest upfront).
2. Add any annual additional contributions you expect to make to the investment.
3. Input the expected annual return for your investments before fees (use a realistic average, e.g., 7% for broad market index funds).
4. Set your investment time horizon in years (how long you plan to hold the investment).
5. Enter the annual expense ratio for the managed fund you are considering (check the fund’s prospectus for this value).
6. Enter the annual expense ratio for the comparable ETF (typically listed on the ETF provider’s website).
7. Select your preferred compounding frequency (monthly is standard for most investment accounts).
8. Click “Calculate Comparison” to view detailed results, or “Reset Form” to clear all inputs.

Use the “Copy Results to Clipboard” button to save your comparison for records or sharing with a financial planner.

Formula and Logic

This calculator uses standard future value formulas adjusted for investment fees to compare managed fund and ETF performance:

• Gross future value (no fees) is calculated first using your expected annual return, initial investment, annual contributions, compounding frequency, and time horizon.
• For each investment type, the net annual return is calculated by subtracting the annual expense ratio from your expected gross return.
• Future value for each investment is calculated using the net return, with compounding applied at your selected frequency.
• Total fees paid for each investment are the difference between the gross future value (no fees) and the net future value after fees.

The comparison highlights both the total final value difference and total fee savings of choosing an ETF over a managed fund.

Practical Notes

Keep these finance-specific factors in mind when interpreting your results:

• Expense ratios are not the only fee: Managed funds may charge additional sales loads, redemption fees, or 12b-1 fees not captured here. Always review a fund’s full fee schedule.
• Tax efficiency: ETFs are generally more tax-efficient than managed funds due to lower portfolio turnover, which can reduce capital gains tax liabilities. This calculator does not account for tax differences.
• Return assumptions: Expected returns are not guaranteed. Past performance does not predict future results, so use conservative estimates if unsure.
• Compounding frequency: Most brokerage accounts compound returns daily or monthly. Monthly compounding is the most realistic default for long-term projections.
• Inflation: This calculator does not adjust for inflation. To calculate real returns, subtract your expected average inflation rate from your expected annual return before inputting.

Why This Tool Is Useful

Managed funds often charge 1% or more in annual fees, while comparable ETFs may charge less than 0.1%. Over long time horizons, these small percentage differences add up to tens of thousands of dollars in lost returns for investors.

This tool helps you:

• Quantify exactly how much you will lose to fees with a managed fund compared to an ETF.
• Make data-driven decisions when choosing between actively managed and passive investment options.
• Show clients or family members the long-term impact of investment fees on wealth building.
• Adjust inputs to test different scenarios, such as higher annual contributions or longer time horizons.

Frequently Asked Questions

What is the difference between a managed fund and an ETF?

Managed funds (also called mutual funds) are actively managed by a professional portfolio manager who buys and sells assets to try to beat the market. ETFs (exchange-traded funds) are typically passively managed, tracking a specific market index, which allows them to charge much lower fees.

Are managed funds ever worth the higher fees?

Very few managed funds consistently outperform their benchmark index after fees over long time horizons. If a managed fund has a strong long-term track record of beating its benchmark by more than its expense ratio, it may be worth considering, but this is rare.

Does this calculator account for dividend reinvestment?

Yes, the future value formula assumes all returns (including dividends) are reinvested automatically, which is standard for most retirement and brokerage accounts.

Additional Guidance

When using this calculator for financial planning:

• Always use the most recent expense ratio data from official fund documents, as fees can change year to year.
• For retirement accounts, consider increasing your annual contribution input to match expected salary growth over time.
• If comparing multiple managed funds or ETFs, run separate calculations for each pair to get accurate comparisons.
• Consult a certified financial planner if you have complex investment goals or need help interpreting results for your specific tax situation.
