What a 1% advisory fee actually costs

Percentage-of-assets pricing is the standard way financial advice is sold in the United States, and it is remarkably easy to underestimate. The fee is quoted as a small number, deducted quietly from the account, and never arrives as a bill. Here is what it actually amounts to.

The arithmetic

Take a $1,000,000 portfolio earning 6% per year before fees, and an advisor charging 1% of assets per year. The fee reduces your compounding rate from 6% to roughly 5%. That single percentage point compounds against you exactly the way returns compound for you:

Over 30 years, the 1% fee consumes about a quarter of the wealth the portfolio would otherwise have produced. This is simple compounding, not a claim about any particular advisor, and you can verify it with any calculator.

The fee rarely travels alone

The advisory fee sits on top of the expense ratios of the funds the advisor selects. A portfolio of funds averaging 0.6% per year under a 1% advisory fee has an all-in cost around 1.6%, before any trading costs or cash drag. The SEC's investor guidance makes the same point in its own examples: seemingly small ongoing fees compound into large differences in final wealth.

What you get for it, and the real question

This is not an argument that advisors do nothing. The research on advisor value, including Vanguard's Advisor's Alpha work, finds that good advisors earn their keep mostly through behavioral coaching, tax awareness, and planning discipline rather than investment selection. Persistent outperformance through fund picking is rare, as the SPIVA scorecards document year after year.

The real question is whether that value should be priced as a percentage of your assets. The work involved in advising a $2 million household is not four times the work of advising a $500,000 household, but the fee is. Three questions expose the economics of any advisory relationship:

• What is my all-in cost in dollars per year, counting fund expenses as well as the advisory fee?
• What specific work is done for that amount in a normal year?
• Which parts of that work require a person, and which are computation and monitoring that software can do continuously?

Asking them is not rude. It is exactly the diligence a good advisor would tell you to apply to everything else you buy.
