A 1% annual fee does not mean an investor simply loses 1% once. When an ongoing fee is based on portfolio assets, part of the account is removed year after year. Those dollars also stop participating in future compounding.
The Investment Fee Calculator compares a projected portfolio with and without an annual fee so the long-term difference can be seen in dollars.
The short answer
A 1% ongoing annual fee can consume far more than 1% of the final portfolio value over a long period because the fee reduces the amount left to earn future returns.
The Securities and Exchange Commission's Investor.gov says investment fees may appear small but can have a major long-term impact. Its current fee bulletin illustrates this with a $100,000 portfolio growing at 4% for 20 years: a 0.25% annual fee leaves about $208,000, while a 1% annual fee leaves about $179,000.
Compare fees in dollars as well as percentages. A fee that looks small on a disclosure can represent a large difference after years of compounding.
A 20-year example
Consider the default assumptions from Sunset Guardian's Investment Fee Calculator, but change the annual fee to 1%:
- Starting balance: $100,000
- Monthly contribution: $500
- Annual return before fees: 7%
- Annual investment fee: 1%
- Time: 20 years
Under the calculator's constant-return assumptions:
- Projected balance without fees: about $640,737
- Projected balance after the 1% fee: about $541,456
- Estimated long-term fee impact: about $99,281
$640,737 - $541,456 = about $99,281
of modeled fee impact
The estimated difference is about 15.5% of the projected no-fee balance. The result includes both amounts removed for fees and growth those dollars might otherwise have earned.
This is an illustration, not a return forecast. Actual returns, fee schedules, taxes, contributions, and investment values change over time.
Compare 0.25%, 0.50%, and 1%
Keeping the same $100,000 starting balance, $500 monthly contribution, 7% assumed return, and 20-year period shows how different ongoing fees change the modeled result:
About $614,264 ending balance
· $26,472 modeled fee impact
About $588,925 ending balance
· $51,812 modeled fee impact
About $541,456 ending balance
· $99,281 modeled fee impact
The percentages differ by less than one percentage point, but the long-term dollar differences are substantial under these assumptions.
Why the cost grows over time
An ongoing fee reduces the amount remaining in the portfolio. When the next period begins, the account has fewer dollars available to earn a return.
That creates two parts to the long-term cost:
- The actual fees removed from the portfolio
- The future returns those removed dollars no longer earn
Investor.gov makes the same point: fees and expenses reduce the money in a portfolio that is able to earn a return.

What the 1% may be charged on
A percentage shown as an annual fee can describe different costs. An investment adviser may charge an asset-based fee as a percentage of assets under management. A mutual fund or exchange-traded fund (ETF) can have annual operating expenses expressed as an expense ratio.
The dollar amount of an asset-based fee can rise as the account grows. A 1% fee on $50,000 is $500 for a year before considering the exact billing method. A 1% fee on $500,000 is $5,000.
Confirm what the percentage applies to, how often it is assessed, and whether other costs are charged separately.
Watch for more than one layer of fees
One account can contain more than one type of cost. Investor.gov identifies ongoing advisory fees, fund operating expenses, retirement-plan fees, and several transaction-based charges.
For example, an investor could pay an advisory fee while also holding funds that have their own expense ratios. A retirement plan may add administrative expenses. Trading or account fees may apply separately.
Do not assume the largest percentage shown on one document is the entire cost. Identify each layer and determine whether it applies to the account, the investment product, particular transactions, or a separate service.
Where to find investment fees
Investor.gov recommends reviewing the disclosures that apply to the investment or service. Useful places to look include:
- Mutual fund and ETF prospectuses
- Standardized fund fee tables
- Customer Relationship Summary (Form CRS) for an investment professional
- Form ADV, the investment adviser registration and disclosure form
- Account-opening documents and fee schedules
- Retirement-plan disclosures
- Account statements and trade confirmations
If the cost is unclear, ask for the fees to be explained in dollars and percentages. Also ask which costs are ongoing and which apply only to particular transactions.
A higher fee is not automatically a bad investment
Cost matters, but a fee comparison should not pretend that every investment or service is identical. Advice, planning, portfolio management, tax services, specialized strategies, insurance features, or other services can have value.
The useful question is whether the services and investment characteristics justify the cost for the investor's needs. When two products provide similar exposure and performance, Investor.gov notes that higher costs require better performance to produce the same return to the investor.
How to test your own fee
Enter the current balance, planned monthly contribution, expected annual return before fees, annual fee, and time period into the Investment Fee Calculator .
Then rerun the same assumptions at several fee levels. Keeping the other inputs unchanged isolates how much the fee changes the modeled ending balance.
Use conservative and moderate return assumptions rather than relying on a single optimistic projection. The calculator assumes a constant fee and return, which real markets do not provide.
Frequently asked questions
Is a 1% investment fee high?
The percentage alone does not describe the service or product. Compare the total costs with similar alternatives and identify what is being provided for the fee.
Is a 1% fee charged on profits?
An asset-based fee is commonly stated as a percentage of assets in the account, not only the year's profit. Fund expense ratios are also based on fund assets. Check the actual disclosure for the fee being evaluated.
Does a 1% fee reduce a 7% return to exactly 6%?
Subtracting the fee gives a useful quick approximation. Sunset Guardian's calculator applies the annual return factor and fee factor separately, so a 7% return and 1% fee produce a modeled annual factor slightly different from simple subtraction.
Do investment fees matter if the account is small?
Yes. The immediate dollar amount is smaller on a smaller balance, but recurring fees still reduce money available for future growth. Fixed monthly or annual fees can also represent a large percentage of a small account.
Where should I compare my actual numbers?
Use the Investment Fee Calculator and test the fee shown in your prospectus, advisory agreement, retirement-plan disclosure, or other account documents.
