Investment Fee Calculator
A 1% fee does not cost you 1%. Enter your balance, your expected return, and the fee you pay — the chart puts fee and no-fee growth side by side, and the number at the top is what the fee removes from your portfolio before you ever see it.

Fee vs. No-Fee Growth
The gap between the bars is the fee. It looks like a rounding error in year 1 and a wing of the house by year 30.
What Fees Cost at Each Milestone
| Year | With Fees | Without Fees | Lost to Fees |
|---|---|---|---|
| 5 | $133,412 | $140,255 | $6,843 |
| 10 | $177,988 | $196,715 | $18,727 |
| 15 | $237,457 | $275,903 | $38,446 |
| 20 | $316,797 | $386,968 | $70,172 |
| 25 | $422,645 | $542,743 | $120,098 |
| 30 | $563,859 | $761,226 | $197,366 |
Fees accrue monthly against your balance, the way a real expense ratio is netted out of a fund's share price. At these inputs, a 1.00% fee turns a 7.00% gross return into 5.93% net.
The 1% Fee That Takes 26% of Your Money
Start with $100,000, earn 7% a year, wait 30 years, and pay a 1% annual fee. You end with $563,859. Pay no fee and you end with $761,226. The fee cost you $197,366 — 25.9% of everything you could have had, extracted by a number that sounds like a rounding error.
One percent sounds small because we hear it as a slice of the balance, once. It is actually a slice of the growth rate, every year, forever. In the compound interest formula, the rate sits in the exponent. Reduce it and you are not shaving the answer, you are bending the curve. At these inputs a 1.00% fee turns a 7% gross return into a 5.94% net return — a drag of about 1.07 points, slightly more than the headline fee, because the fee is charged on the balance after it grows.
Another way to feel the same fact: to reach the balance that the fee-free portfolio hits in year 30, the fee-paying portfolio needs until year 36. The fee costs six years of your life at work.
The Fees You Pay Are Not What Fees Cost
Across those 30 years, the actual dollars skimmed from the account total $80,716. But you finished $197,366 behind. The missing $116,651 is the return those fee dollars would have earned had they stayed invested — growth that never happened, and therefore never appeared on any statement as a loss.
This is why fees get worse with time rather than merely adding up. Each dollar removed early is a dollar that cannot compound for the remaining decades:
| After | Fees paid | Actually lost | Cost per $1 of fees |
|---|---|---|---|
| 10 years | $13,571 | $18,727 | $1.38 |
| 20 years | $37,725 | $70,172 | $1.86 |
| 30 years | $80,716 | $197,366 | $2.45 |
By year 24, the cumulative damage exceeds the $100,000 you originally invested. The fee has, at that point, quietly cost you more than the entire portfolio you started with. Stretch the horizon to 40 years and the fee takes $493,845 — a full 33% of the $1,497,446 you would otherwise have held.
What Each Fee Level Costs
Same $100,000, same 7% return, same 30 years. Only the fee changes:
| Annual fee | Typical of | Ending balance | Lost to fees |
|---|---|---|---|
| 0.03% | Broad index fund | $754,405 | $6,820 |
| 0.25% | Robo-advisor | $706,216 | $55,009 |
| 0.50% | Actively managed fund | $655,172 | $106,053 |
| 1.00% | Advisor AUM fee | $563,859 | $197,366 |
| 1.50% | Advisor plus active funds | $485,242 | $275,983 |
| 2.00% | Legacy annuity or insurance product | $417,560 | $343,665 |
Read the first and fourth rows together. The gap between a 0.03% index fund and a 1% advisor is $190,546 on a $100,000 portfolio — more than the portfolio itself. Nothing about the underlying investment changed; the market delivered 7% in both rows. The only difference is who kept the money.
Fees Stack, and They Hide
The reason fees are so easy to ignore is that you never write a check for them. An expense ratio is netted out of the fund's share price before the return is reported. An advisory fee is usually debited straight from the account. Your statement shows a number that is already net of both, so the cost is invisible by construction.
They also add together. If you pay an advisor 1% to put you in funds that charge 0.03%, your real drag is 1.03%. That combination ends 30 years at $558,803 against $754,405 for the index fund held directly — a $195,602 difference. Add the two percentages together and put the total in the fee field above.
Where to look for yours:
- Fund expense ratio.Listed on every fund's page and in the prospectus, as an annual percentage of assets.
- Advisory or AUM fee. Usually quoted as a percentage of assets per year, billed quarterly. Ask for it as a percentage, not a dollar amount.
- 401(k) plan administration fees.Disclosed separately from fund expenses in your plan's annual fee notice, and layered on top of them.
- Wrappers. Variable annuities and insurance-linked investment products can carry mortality and expense charges on top of the fund fees inside them.
A tax shelter does not protect you from any of this. Inside a Roth IRA, growth is permanently tax-free — which means every dollar a fee removes is a dollar of tax-free growth you never get back. The wrapper protects you from the IRS, not from your fund. And if you are still deciding which vehicle the money belongs in at all, the HYSA vs CD vs index fund comparison is the step before this one — a low-fee index fund only wins if the money can stay invested long enough for the fees on this page to be the thing that matters.

Frequently Asked Questions
How much do investment fees cost over time?
Far more than the fee percentage suggests. On $100,000 growing at 7% for 30 years, a 1% annual fee leaves you with $563,859 instead of $761,226 — a loss of $197,366, or 25.9% of the balance you would otherwise have had. The reason a 1% fee costs 26% is that it is charged every year, on a balance that keeps getting bigger, and the money it removes stops compounding.
Why is the amount I lose bigger than the fees I paid?
Because each dollar taken as a fee also stops earning returns for every year that follows. In the $100,000 example above, you hand over $80,716 in actual fees across 30 years — but you end up $197,366 poorer. The missing $116,651 is growth those fee dollars would have produced had they stayed invested. The gap widens the longer you hold: at year 10 each $1 of fees has cost you $1.38, by year 20 it is $1.86, and by year 30 it is $2.45.
How do I calculate the impact of an expense ratio?
A quick estimate is to subtract the expense ratio from your expected return and run a normal compound-interest projection — a 7% return with a 0.50% expense ratio behaves roughly like a 6.5% return. That shortcut is slightly optimistic, because the fee is charged on the balance after growth rather than before it. The calculator on this page does the exact version: it grows the balance each month, then removes one-twelfth of the annual fee, the way a fund nets its expense ratio out of the share price.
What is a good expense ratio?
Broad-market index funds are commonly available in the range of a few hundredths of a percent — 0.03% to 0.10% is typical for a total-market or S&P 500 index fund at a major brokerage. Anything approaching 1% deserves a hard look, because at that level the fee is no longer a rounding error on your return; it is a quarter of your 30-year wealth. Compare any fund you own against the cheapest index fund tracking the same market, and treat the difference as the price of whatever the expensive fund promises.
Is a 1% advisor fee worth it?
Sometimes — but you should know the price. On $100,000 over 30 years at a 7% return, a 1% assets-under-management fee costs $197,366. An advisor who keeps you from panic-selling in a crash, or who saves you more than that in tax planning, can be worth it. An advisor who simply puts you in index funds you could have bought yourself is charging you a wing of your house for paperwork. The question is never 'is 1% a small number' — it is 'is this service worth a quarter of my final balance.'
Do fees matter inside a Roth IRA or 401(k)?
Yes, and arguably more. A Roth IRA shelters your growth from taxes entirely, which means every dollar a fee removes is a dollar of permanently tax-free growth you never get back. The tax wrapper protects you from the IRS, not from your fund. Many 401(k) plans layer an administrative or advisory fee on top of each fund's expense ratio, so check both — the plan's fee disclosure lists them separately.
What happens if I pay both an expense ratio and an advisor fee?
They stack, and you should add them together before running any projection. A 1% advisor fee on top of a fund charging 0.03% is a 1.03% total drag. Over 30 years on $100,000 at 7%, that combination ends at $558,803 versus $754,405 in the index fund alone — a $195,602 difference produced by a fee you might never see on a statement, because both come out silently before the return is reported to you.
