How much do financial advisors cost?
Last updated August 2026
Short answer
The number that matters is not the headline percentage. It is the percentage plus fund costs, applied to a balance that grows, for as long as the relationship lasts.
The four models
Assets under management: a percentage of the portfolio, frequently around 1%, sometimes tiered downward as the balance grows.
Flat fee: a fixed annual or project amount for planning, independent of portfolio size.
Hourly: charged for time on a defined question. Commission: paid through the products sold, so the cost is embedded rather than invoiced.
What a percentage fee compounds into
On $500,000, a 1% fee is $5,000 a year, and the amount rises with the balance rather than with the work.
Because the fee is deducted from money that would otherwise have compounded, its long-run cost is considerably larger than the sum of the annual charges.
Over a working life, a percentage point of annual cost consumes a meaningful share of the final balance, which is the same arithmetic that makes fund fees matter.
The fee is not the whole cost
Fund expense ratios are charged inside the funds and are additional to the advisory fee.
Some arrangements add platform or custody charges, and commission-based products can carry their own internal costs.
Adding all of it together is the only comparison that means anything, and it is the one most rarely made.

When each model fits
A percentage fee suits somebody who wants ongoing management and does not want to think about it, and it is the most expensive way to buy a portfolio of index funds.
A flat fee suits a large balance with a straightforward situation, where the percentage would pay for the size rather than the complexity.
Hourly suits a specific question with a defined answer, implemented by you afterwards.
How to find out what you are paying
Form ADV Part 2 states the fee schedule in plain language, and Form CRS summarises it in two pages.
Ask for the total annual cost in dollars, including fund expenses, for a portfolio of your size.
A firm that cannot produce that figure quickly has answered a different and more useful question than the one you asked.
A comparison worth running
Take your current balance, multiply by the advisory fee, and add the weighted expense ratio of the funds held.
Compare that annual figure against what a flat-fee planner would charge for a review every few years, plus the cost of holding the same funds yourself.
For a straightforward portfolio the gap is frequently large. For a genuinely complex situation it frequently is not, and knowing which case you are in is the whole point of the exercise.

FAQ
How much do financial advisors charge?
+
The common model is a percentage of assets under management, frequently around 1% a year and often on a sliding scale for larger balances. Flat annual fees, hourly rates and commission-based compensation are the alternatives.
What does 1% actually cost?
+
On a $500,000 portfolio, $5,000 a year, and it rises with the balance whether or not the work does. Over decades the compounded cost of the fee is a large multiple of the annual figure.
Is the fee on top of fund costs?
+
Yes. The advisory fee is charged in addition to the expense ratios of the funds held, so the total annual cost is both together. Comparing only the advisory fee understates what you pay.
What is a flat-fee advisor?
+
One charging a fixed annual or project fee for planning, independent of the portfolio size. It suits people with a large balance and a straightforward situation, where a percentage fee would be paying for the balance rather than the work.
What about hourly advice?
+
Hourly advisers charge for time and are well suited to a defined question: a retirement plan, an equity compensation decision, a second opinion. You implement the result yourself, which is what keeps the cost contained.
How does commission-based compensation work?
+
The adviser is paid through the products sold, so the cost is embedded rather than billed. It is not automatically bad and it does create an incentive worth understanding, which the Form ADV or Form CRS will describe.
How do robo-advisors compare?
+
Typically a fraction of a percent, plus the underlying fund costs. They deliver allocation and rebalancing rather than planning, so the comparison is only fair for people who wanted allocation and rebalancing.
Is it worth it?
+
For a straightforward portfolio, a percentage fee is expensive for what it delivers. For genuine complexity, equity compensation, a business sale, estate planning, the advice can be worth many times the cost, and an hourly or flat fee frequently delivers it more cheaply.
How do I compare two arrangements fairly?
+
Convert both to an annual dollar figure including fund expenses. Then compare that against what a flat-fee planner would charge for a periodic review plus holding the same funds yourself. For a simple portfolio the gap is usually large, and for genuine complexity it usually is not.
