Why this page exists

Fees can look small in percentage terms and still take a much larger bite out of long-term growth than most people expect. This calculator helps visitors compare an ending balance before fees with an ending balance after fees so the long-term drag becomes easier to understand.

How it works

What the calculator is doing

Enter the starting balance, annual contribution, expected return, annual fee percentage, and number of years.

The calculator projects one ending balance without fees and another ending balance with the annual fee assumption applied each year.

It shows the estimated dollars lost to fees over time so the comparison feels more practical.

Understanding your result

The fee impact is not only the dollars paid directly. It also includes the growth those dollars no longer get to earn later, which is why the long-term difference can grow faster than people expect.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Compare two account options

Use one fee level for a lower-cost account and another for a higher-cost option to see how the long-term difference builds.

Check the drag on retirement investing

This can be useful when you want a cleaner picture of how fees may affect a long retirement horizon.

Put a small percentage into dollar terms

A fee that looks minor on paper often feels more real once it is turned into a long-term dollar estimate.

FAQ

Common questions

Why can a small annual fee matter so much over time?

Because the fee reduces the balance that keeps compounding in later years, so the long-term impact can be much larger than the fee percentage first suggests.

Does the dollars-lost figure include lost growth?

Yes. It reflects the ending-balance gap between the no-fee estimate and the fee-adjusted estimate, so it includes both direct fees and missed compounding.

Is this a guaranteed projection?

No. It is a planning estimate based on one steady return and fee assumption, while real returns and fee structures can change over time.
