Tip. A 0.85% fee looks trivial in a year and severe over twenty-five.

Assumptions

  • Compares monthly compounding at the gross return against the same schedule at gross minus fee.
  • The fee is charged on the whole balance every year, which is how expense ratios and most advisory fees work.
  • Fee drag = the gap between the two ending balances. It is larger than the fees paid because the fees never compound for you.
  • Ignores taxes and any performance difference between the two options.

Example 3

Fund plus advisor fee

What this calculates

Shows how an annual fee compounds against the same gross return. The gap is usually far larger than the fees paid, because every dollar taken in fees also stops compounding for you.

How to use it

  1. Start with starting balance and work down the form, or load an example to begin from a realistic case.
  2. Read the headline result alongside the supporting rows, which show the intermediate figures behind it.
  3. Check the assumptions. They decide what the number includes and, more importantly, what it leaves out.
  4. Sweep annual fee on the response curve to see how much it actually moves the answer.
  5. Run a cautious case as well as an optimistic one before using the estimate in a decision.

Common mistakes

  • Comparing funds on past returns while ignoring the fee difference.
  • Counting only the fund's expense ratio when an advisor fee sits on top.
  • Assuming a fee is fine because it is charged quietly rather than billed.

Formula

Compare ending balances at the gross return against (gross − fee), both compounded monthly

Inputs

  • Starting balance
  • Monthly contribution

FAQ

Are expense ratios the only fee?

No. Advisory fees, platform or wrap fees, trading costs, and fund-level transaction costs all stack. Enter the all-in annual drag you want to test.

Why is the drag so much larger than the fees I pay?

Because the fee is charged on the whole balance every year, and the money taken never earns anything afterwards. Over decades the lost compounding dwarfs the fees themselves.

Is a higher fee ever worth it?

It has to be paid for with reliably higher returns or with a service you value, such as planning or tax work. The bar is high: this page shows exactly how much extra return the fee needs to earn back.

Are these numbers financial advice?

No. They are educational estimates based on the inputs and assumptions on this page. Confirm important decisions with a qualified professional and your own documents.
