A stockbroker is paid to buy and sell investments for you, usually through a commission or charges built into what you buy, and owes you a best-interest duty when they recommend something. A financial advisor registered as an investment adviser is paid to advise you, usually by a fee you can see, and owes a fiduciary duty for the whole relationship. The catch is that the title “financial advisor” doesn’t tell you which one you’ve got. At the end of 2025, 331,802 people were registered as both, and only 94,562 were registered as advisers alone. So the question to ask isn’t “advisor or broker?” but “which role are you in, and how are you paid?”
This guide is about the person across the table. For how the two kinds of firm are regulated, see RIA vs broker-dealer.

Who you’re actually talking to
“Stockbroker” covers three different experiences today:
- An online brokerage account. No person at all. You place your own trades, often for nothing.
- A broker who calls you with ideas. A registered representative paid when you buy, sell or hold certain products.
- A “financial advisor” at a brokerage firm. Usually registered as both, so they can open an advisory account for a fee or a brokerage account for commissions, and recommend moving money between them.
That third group is the largest, and it’s where people get confused. A dual registrant is a fiduciary on the advisory account and a broker on the brokerage account. The dual registrant entry explains how that works.
The one rule about the title
Brokers can’t simply call themselves advisors. Under Regulation Best Interest, the SEC presumes it’s a violation for “a broker-dealer that is not also registered as an investment adviser” or “an associated person that is not also a supervised person of an investment adviser” to use “adviser” or “advisor” in a name or title.
So a broker with “advisor” on the card should also be registered with an investment adviser. (People who sell only insurance aren’t covered by this rule.) It doesn’t tell you whether they’re acting as one for your account, or whether they also earn commissions. Our guide to financial planner vs financial advisor covers the other titles.
How each is paid, and what you see
Online, you often pay nothing per trade. Fidelity, for example, charges $0 for online US stock and ETF trades and $0.65 per options contract, with a minimum $19.95 markup on bonds traded through a representative. The firm earns money in other ways, but there’s no advice to pay for.
With a broker, the pay is in the transaction. A full-service firm’s Form CRS has to say how that works. Edward Jones, a large dual registrant, puts it plainly in its own: “The more trades in your account, the more you pay us. As a result, we have an incentive to encourage you to trade more often in your account.” It also says it doesn’t provide investment monitoring for those brokerage accounts. Funds and annuities can carry sales charges and trail commissions on top of their running costs.
With an advisor, the pay is a fee. Among fee-only firms that publish prices, the median is 1% of assets a year (middle half 0.95% to 1%), $4,500 a year for flat ongoing planning, $2,000 for a one-time plan or $300 an hour. The Edward Jones summary sums up the trade-off well: “You will typically pay more in upfront fees and commissions through brokerage services and more over time through investment advisory services.”
Which costs less depends on what you do. A few trades a year in funds you hold for a decade can cost less through a broker. Ongoing advice on your whole situation usually costs less, and is easier to see, through a fee. Our guide to fee-only vs fee-based vs commission goes through each way of paying.
When a stockbroker is the better choice
- You make your own decisions. A self-directed online account is cheaper than any advisor.
- You want one purchase, then to hold. A single fund, bond or annuity you’ve already decided on, where paying once costs less than paying every year.
- You trade often and want execution, not advice. Speed and price per trade matter more than planning.
If a broker recommends something large or hard to undo, like an annuity, paying a fee-only planner for an hour to review it first is cheap insurance.
When a financial advisor is the better choice
- You want advice on more than investments. Retirement income, taxes, Social Security, estate planning. See retirement planning advisors in the public graph.
- You want someone watching. An advisor who agrees to monitor your accounts has to keep doing it.
- You want the price in dollars. A fee-only advisor shows the whole cost and earns nothing from what you buy. Flat-fee advisors take that one step further and don’t charge by the size of your account.
How to check which one you’re talking to
- Search the person on BrokerCheck and on the SEC’s adviser search. A broker shows on the first, an adviser representative on the second, and someone on both can act in either role. The CRD number links the records.
- Read the first lines of the firm’s Form CRS. It has to say whether the firm is a broker-dealer, an investment adviser or both, and how you’ll pay.
- Ask for each account: “Is this a brokerage account or an advisory account, and are you acting as my broker or my adviser?” The answer should match your account agreement and statements.
- Ask how they’re paid on what they recommend. “Do you or your firm earn anything if I buy this?” A fee-only advisor’s answer is no.
