Financial Advisor Fee Calculator: Annual Cost and Compounding

Updated September 26, 2026.

To estimate an annual AUM fee, multiply the billable assets by the applicable rate. A complete fee calculator also needs the contract's tier rules, billing basis and additional expenses. Your total net worth is not necessarily the amount subject to the fee.

This guide gives formulas and a worksheet you can reproduce. It does not estimate the value of a service by assuming every advisor or self-directed investor earns the same actual return.

Calculate a simple annual charge

For a flat percentage applied to a constant balance:

Annual charge = billable balance × annual rate

A hypothetical $750,000 balance at 1% produces $7,500 annually. At 0.75%, it produces $5,625. At 0.25%, it produces $1,875. Dividing by 12 gives a monthly equivalent, not necessarily the billing schedule in the agreement.

Actual charges can vary with balances, minimums and the provider's calculation method. Ask whether billing uses an average balance, a period-end balance or another defined method.

Handle tiers correctly

Suppose an invented schedule charges 1% on the first $500,000 and 0.75% on the next $500,000. A $1 million account would pay $5,000 plus $3,750, totaling $8,750. The blended rate is 0.875%.

That differs from a breakpoint schedule that applies a new rate to the whole balance once a threshold is reached. Do not apply the lowest marginal rate to all assets unless the agreement says to do so.

Record the tiers as separate rows. Multiply each slice by its rate, add the charges and divide by total billable assets to find the blended rate.

Model compounding with explicit timing

For a simplified model with a constant gross return and a fee charged at year-end after growth:

Next year's balance = this year's balance × (1 + gross return) × (1 − fee rate)

Starting with $100,000, assuming a constant 5% gross return and a 1% year-end fee, the first year's balance is $103,950. Without that fee it would be $105,000. The difference is $1,050 because the fee is applied after growth in this particular model.

A model that subtracts one percentage point from the assumed return produces a different result. Neither should be used without stating the convention. Actual billing can occur more frequently and on a different balance basis.

The SEC's fee guide explains why ongoing expenses affect the assets available to compound. It does not make a constant-return illustration a prediction. Investor.gov fee guide

Fixed annual subscriptions use a different formula

If a hypothetical fixed fee is paid from the portfolio after annual growth:

Next year's balance = this year's balance × (1 + gross return) − fixed annual fee

With the same $100,000 and 5% assumption, subtracting $399 leaves $104,601. That reflects Mezzi Advisory's current annual price, but it does not compare equivalent service or actual investment results. Mezzi pricing

A fixed fee paid from outside the investment account changes the displayed account balance, but the household still bears the expense. Keep that funding assumption consistent across comparisons.

For a longer worked model, see the 1% fee on a $1 million portfolio.

Include the costs the headline misses

Do not subtract fund expenses twice from a return already reported net of those expenses. Do not add a professional task as an extra charge if the quoted engagement already includes it. The goal is a complete, non-overlapping total.

A fee comparison is not a value comparison by itself

Two services can have different prices because they do different work. A managed relationship may implement decisions; a self-directed tool may help you analyze while leaving implementation to you.

Mezzi connects supported investments, banking, other assets and liabilities. AI Personalization adds goals and rules; Exposure X-Ray helps investigate supported fund exposure. It does not execute trades. Mezzi account groups

Free includes aggregation and limited AI. Advisory is $399 annually and Concierge $999 annually. If you retain an advisor and add a subscription, add both costs. If you replace part of the relationship, identify who performs the remaining work.

Use a tiered test case to catch formula errors

Suppose a hypothetical schedule charges 1% on the first $1 million and 0.75% on the next $500,000. At a constant $1.5 million covered balance, the annual fee is $10,000 plus $3,750, or $13,750. The blended rate is approximately 0.9167%.

These are invented terms for checking a worksheet, not a provider quote. Use the actual agreement to determine whether tiers are marginal or apply differently and how billing balances are measured.

Then test the comparison's scope: if the advisor manages only $1 million of a $1.5 million household portfolio, do not bill the other $500,000 in the model. A correct spreadsheet with the wrong covered balance still gives the wrong answer. Save the fee schedule and balance date alongside the calculation so another person can reproduce it.

Validate your worksheet

Check the first year manually, then compare the model with the actual agreement. Change one assumption at a time to see which inputs drive the result. Keep taxes, inflation, contributions and withdrawals visible as included or omitted.

A useful calculator makes the cost understandable. The final decision also needs a clear description of the service, your willingness to implement and the value of work you would otherwise need to replace.

Frequently asked questions

How do I calculate a 1% annual fee?

Multiply the billable balance by 0.01, subject to the agreement’s billing basis, tiers and minimums.

Is a marginal tier the same as a blended rate?

No. A marginal rate applies to a slice of assets; the blended rate is the total charge divided by the total billable balance.

Why do fee calculators produce different results?

They may use different fee timing, balance definitions, return assumptions, contributions or expense treatment. Compare the assumptions.

Does a lower fee prove a service is better?

No. Compare the work included, implementation responsibility and complete costs alongside the fee arithmetic.
