Investment fee calculator guide
Small annual fees can create large long-term differences because the money lost to fees also loses future compounding potential.
How to use it
- Enter your starting balance and monthly contribution.
- Use the expected return before annual fund fees.
- Enter the annual fee or expense ratio you want to test.
- Compare the selected fee with common fee levels in the table.
Calculation method
Fee-adjusted return = annual return − annual fee
The calculator compounds monthly and compares the projected value with and without the selected annual fee.
Example scenario
A 1% annual fee can look small in year one, but over 30 years it can remove tens or hundreds of thousands of dollars from a long-term portfolio.

FAQ
Is an expense ratio the same as a fee?
For this calculator, yes. It treats the annual fee as a drag on the portfolio return.
Does this include trading costs?
No. It focuses on recurring annual fees and expense ratios.
Why compare 0.25%, 0.5%, 1%, and 2%?
Those levels show how quickly long-term cost rises as fees move from low-cost index funds to higher-cost products.
