What Do Financial Advisors Do and How Do You Choose One?

A financial advisor helps you plan and manage your money — typically covering retirement planning, investment selection, and other long-term goals. You likely need one if your situation involves multiple accounts, tax considerations, or decisions you don't feel equipped to make alone; you may not need one if your finances are simple and you're comfortable managing a basic portfolio yourself. The sections below explain what advisors actually do, how they're paid, and what to check before hiring one.

What financial advisors typically do

The scope varies widely by firm and by the individual advisor's credentials. Common services include:

• Financial planning — building a strategy around goals like retirement, education savings, or major purchases.
• Investment management — selecting and rebalancing funds, ETFs, or individual securities on your behalf.
• Retirement guidance — projecting income needs, coordinating accounts, and planning withdrawals.
• Tax-aware advice — structuring accounts and timing decisions with tax consequences in mind (though advisors generally are not tax preparers unless separately licensed).
• Estate planning coordination — working alongside attorneys on wills, trusts, and beneficiary designations.

Vanguard, for example, describes its advisory services as support "at every step — from your first investment through retirement," and notes that some services are tiered by asset level: its estate planning offering is described as "exclusively available to investors with $5 million in Vanguard funds or ETFs." That tiering is a useful illustration of a broader point — what an advisor will do for you often depends on how much you're investing.

Types of advisors and how they're paid

The fee model matters as much as the service list, because it directly affects your net returns over time.

Vanguard's site references both human advisory services and robo-advisor options, and points users to a "Review fees and commissions" page — a reminder that fee details are published and worth reading before you commit, not after.

Fiduciary vs. suitability standard

This distinction is one of the most important things to understand before choosing an advisor.

• Fiduciary standard: The advisor is legally required to act in your best interest. Registered Investment Advisers (RIAs) generally operate under this standard.
• Suitability standard: The advisor must recommend products that are suitable for you — but not necessarily the cheapest or best available. Some broker-dealers operate under this standard.

How to check: Ask directly, "Are you a fiduciary at all times, for all advice you give me?" Get the answer in writing. You can also verify credentials and disciplinary history through regulatory databases like the SEC's Investment Adviser Public Disclosure (IAPD) and FINRA's BrokerCheck.

Do you need an advisor?

There's no universal threshold, but these questions help:

• Is your situation complex? Multiple income sources, business ownership, stock options, or estate concerns push toward professional help.
• Do you have the time and interest? Managing a portfolio isn't hard, but it requires attention and emotional discipline during downturns.
• What's the cost relative to the benefit? A 1% annual fee compounds significantly over decades. For a simple index-fund portfolio, that fee may not be justified.
• Are you close to retirement? Withdrawal sequencing and tax planning get more consequential as you approach and enter retirement.

Vanguard's own framing centers on four principles — "goals, balance, costs, and discipline" — which is a reasonable checklist for evaluating whether any advisor (including a robo-advisor) is delivering value on each dimension.

Questions to ask before hiring

1. What are your credentials? (CFP®, CFA, CPA/PFS, etc.)
2. Are you a fiduciary 100% of the time?
3. How exactly are you paid — and do you receive commissions on any products you recommend?
4. What's included in the fee, and what costs extra?
5. Who holds my assets? (A third-party custodian is generally a good sign.)
6. What's your investment philosophy, and how do you handle market downturns?
7. Can I see a sample plan and a written fee schedule?

Red flags

• Vague or evasive answers about fees or compensation.
• Pressure to move assets quickly or to a specific product.
• No third-party custodian holding your assets.
• Promises of guaranteed returns.
• Reluctance to put fiduciary status in writing.

Where to start

Vanguard's site offers a "Compare services" entry point for its advisory offerings, alongside fund, ETF, and cash management products, and states that over 50 million investors use the platform (as of December 31, 2025). If you're evaluating any provider, use the same process: confirm the fee model, verify fiduciary status, check regulatory records, and make sure the service level matches your actual complexity — not more than you need, and not less.
