How Much Am I Paying in Investment Fees? Build a Checkable Total

Updated September 26, 2026.

To estimate investment fees, separate fund expenses, advisory charges, account costs and subscriptions. Calculate each from its own documents and balance, then combine compatible amounts without double counting. Mezzi can help frame the review using supported accounts, but a connected portfolio is not proof that every charge has been captured.

The useful question is not only “How much?” It is also “For which service, over which period, and based on which evidence?” This guide builds a reproducible worksheet. It does not present member savings, question-volume statistics or conversion results.

Start with the cost layers

The SEC identifies both ongoing and transaction costs and recommends checking documents and statements. A charge does not need to appear as a separate debit to affect your investment result. SEC fee guidance

Calculate a weighted fund estimate

Consider a hypothetical portfolio with these holdings and current expense ratios:

Multiply each holding value by its expense ratio, then add the dollar estimates. Divide $900 by $350,000 to obtain approximately 0.257%. A simple average of the three percentages would incorrectly give each fund equal weight despite the different balances.

This is an annualized snapshot, not the exact amount paid during a year of changing values. Confirm the applicable share class and current expense ratio. Fund A, B and C are invented examples, not recommendations.

Add other charges on the correct base

Suppose only $250,000 of that hypothetical portfolio is subject to a 0.80% annual advisory fee. At a constant billable balance, that charge is $2,000. Add a hypothetical $100 account charge and a $399 annual software subscription, and the combined illustration is:

The total is approximately 0.971% of the $350,000 portfolio, but that blended ratio should not obscure the different billing bases. The subscription does not increase automatically with that portfolio value, while the example advisory charge does.

This scenario is not a statement about your fees or an assertion that each charge applies to every account. Replace every row with actual documents and identify anything excluded, such as transaction costs or outside professional work.

Avoid three common counting errors

Do not subtract fund expenses twice from reported performance. Fund operating expenses are generally reflected in fund returns. A cost inventory and a performance calculation serve different purposes. SEC fund-expense guidance

Do not apply an advisor's rate to assets outside the agreement. Ask which accounts and cash balances are billable, how tiers work and whether the invoice uses beginning, ending or another valuation method.

Do not call every price difference a saving. A new arrangement may replace only part of the old service or add another subscription. Include the work you would retain or take on.

What a Mezzi conversation should help clarify

Mezzi's supported account view and AI Personalization can help connect a fee question with your goals and existing arrangement. Investments can be reviewed alongside banking, liabilities and manual assets. Mezzi account groups

Ask: “Which costs are visible, which require documents, and what assumptions are being used in this estimate?” A useful answer distinguishes known holding information from missing invoices, plan charges or share-class details.

Do not assume the application has detected every fee or verified every billing term. Reconcile the result with source documents. Mezzi's own subscription belongs in the cost inventory if you choose a paid plan; Advisory is currently $399 annually and Concierge $999 annually. Mezzi pricing

Decide what is worth investigating

A high-cost holding is a prompt to understand its role and available alternatives. Compare exposure, risks, service and any consequences of changing it. An appreciated taxable holding may create a separate decision about whether and how to make a transition.

For an advisory charge, compare the deliverables with the agreement: implementation, planning, coordination, access and the responsibilities you want delegated. A cheaper service that does different work is not an identical replacement.

Use the advisor cost breakdown for the broader engagement comparison. Keep the current fee inventory as the evidence behind that discussion.

Keep the worksheet current

Record the document date beside each line. Revisit it when you change providers, move assets, change share classes or receive a new fee schedule. Compare estimated charges with actual invoices where available.

The first success is a total you can explain. The next is a considered decision about any cost that does not fit the service or investment you want—not an automatic trade based on the largest percentage in a table.

Frequently asked questions

How do I calculate my weighted fund expense ratio?

Multiply each holding’s value by its expense ratio, add those dollar estimates, and divide by the total included value. A simple average of ratios is incorrect when holdings have different weights.

Does Mezzi automatically see every investment fee?

Do not assume complete coverage. Advisory invoices, plan costs, account terms and share-class details may require separate documents. Reconcile any estimate with the sources.

Are fund expenses already included in returns?

They are generally reflected in fund returns. Avoid subtracting them again from a reported return that already includes those expenses.

Is a lower fee always a reason to switch?

No. Compare the investment or service, transition consequences, taxes and the work you would take on. A price difference is an input to the decision, not the decision itself.
