A 1% fee sounds tiny. See what it actually costs.
Fee disclosure is buried in fund documents for a reason. Compare a low-fee fund against a high-fee fund or advisor and see the real dollar gap over time.

Full breakdown
Fees paid is a simplified monthly estimate — actual fund and advisor fee structures vary (quarterly billing, average daily balance, etc.). Use this for comparison, not as an exact bill.
Investment returns shown are hypothetical. Past performance does not guarantee future results. Actual returns vary based on market conditions. This is not investment advice. Consult a licensed financial advisor.
How fees compound against you
An investment fee isn't charged once — it's charged every year, on your entire balance, including the portion of your balance that came from previous years' growth. That means a fee doesn't just take a small bite out of your returns each year; it takes a bite out of money that would otherwise have kept compounding for decades. A 1% annual fee on a balance that would have grown to $1,000,000 over 30 years doesn't cost you 1% of $1,000,000 — it costs you all the additional growth that 1% would have generated by compounding year after year, which is a dramatically larger number.
Expense ratios explained
An expense ratio is the annual fee a fund charges, expressed as a percentage of your investment, automatically deducted from the fund's returns before you ever see them. A 0.03% expense ratio (typical for a broad index fund) costs $3 a year per $10,000 invested. A 1% expense ratio (common for actively managed funds) costs $100 a year per $10,000 invested — over 33 times more for the same investment amount. That difference is invisible on any statement, since it's deducted before performance is reported, which is exactly why so few investors notice how much they're actually paying.
The difference 1% makes over decades
On a $100,000 portfolio with $500 monthly contributions over 30 years at a 7% assumed return, the difference between a 0.03% fee and a 1% fee is commonly well over $150,000 by the end — not because the fee itself is huge in any single year, but because that extra 1% compounds against you every single year for three decades. This calculator's signature number exists specifically to make that compounding effect visible, since it's almost impossible to feel intuitively from a single year's statement.
Index funds vs active management
Index funds track a market benchmark and charge very little because there's no active stock-picking involved — the fund simply holds what the index holds. Actively managed funds employ professional managers attempting to beat the market, and charge meaningfully more for that effort. The well-documented track record is that the large majority of actively managed funds fail to beat their benchmark index over long time horizons, after fees — which means investors are often paying significantly more for a result that, on average, underperforms the cheaper alternative. There are exceptions and reasonable arguments for active management in specific contexts, but the base case strongly favors starting with low-cost index funds unless you have a specific, well-considered reason to pay more.
Frequently asked questions
What's a reasonable expense ratio to look for?
Broad market index funds commonly charge 0.03-0.10%. Anything noticeably above that should have a clear justification — specialized strategy, strong track record, or specific exposure you can't get cheaply elsewhere — rather than being accepted by default.
Does a 1% advisor fee work the same way as a fund expense ratio?
Yes — an advisor's assets-under-management fee compounds against your balance the same way a fund's expense ratio does. If you're paying both a fund expense ratio and an advisor fee, the combined drag can be substantial over decades.
Are actively managed funds ever worth the higher fee?
Sometimes, in specific niches or for investors with particular needs, but the broad historical evidence shows most actively managed funds underperform low-cost index alternatives over long periods after fees. Any active fund should be justified by something specific, not assumed to be worth its higher cost by default.
Why don't I notice fees on my statement?
Expense ratios are deducted directly from fund performance before returns are reported to you, so they never appear as a separate line-item charge. That invisibility is exactly why fee impact is so easy to underestimate without a calculator like this one.
How much does the assumed return rate affect the result?
It affects the absolute dollar figures but not the core conclusion — a higher fee always compounds against you more over time regardless of the underlying return assumption. Adjust the return assumption to match your own expectations and the comparison will still hold directionally.
Is a 0.5% fee difference really worth worrying about?
Yes, especially over multi-decade horizons. Even a half-percent difference compounds into a substantial dollar amount on larger balances over 20-30 years — run your own numbers through this calculator to see the specific impact on your situation.
