Robo-Advisor vs. Financial Adviser: Which One Fits You?

Short answer: The main robo-advisor vs. financial adviser difference is who builds your plan. A robo-advisor is an automated program: you answer an online questionnaire and it builds and manages a portfolio for you, often at a lower cost. A human financial adviser gives ongoing advice and may also help with financial planning. Robo-advisors follow the same securities laws as registered investment advisers, and you can check either one on Investor.gov before you sign up.

You'll see both spellings, "advisor" and "adviser." The SEC uses "robo-adviser," and that's the term in the government sources quoted below. Either way, you're choosing how much of your investing you hand to software and how much to a person.

What Is a Robo-Advisor?

The SEC describes a robo-adviser as an automated digital investment advisory program. In its 2017 investor bulletin on robo-advisers, it explains the basic process:

1. You fill out an online questionnaire about yourself, such as your goals and how comfortable you are with risk.
2. The program uses your answers to create an investment portfolio for you.
3. It then manages that portfolio, and you manage the account online.

Robo-advisers don't all invest the same way. The SEC notes that different robo-advisers have different approaches; some, for example, focus on a limited range of investment products, such as broad-based exchange-traded funds (ETFs). It also cautions that some of these services may not have been tested in stressed market conditions.

What Does a Human Financial Adviser Do?

According to Investor.gov, investment advisers typically provide ongoing advice about buying, selling and holding investments, and they monitor how your investments perform. Some also give advice on market trends or asset allocation, or offer financial planning services.

Investment advisers are required to act in your best interest and not put their interest ahead of yours. The way an adviser is paid can still create conflicts of interest, so the SEC suggests asking about them. Our guide to fiduciary vs. non-fiduciary advisers explains how that duty compares with the rules for brokers.

Robo-Advisor vs. Human Adviser: How Do They Compare?

	Robo-advisor	Human financial adviser
How advice is created	Automated program, based on your questionnaire answers	A person reviews your situation and gives ongoing advice
Access to a person	Varies: some offer an investment professional, others only technical support	A person gives the advice
Typical pricing	Often aims to cost less than traditional advisory programs	Typically a fee based on the value of the assets in your account; may charge other fees
What it considers	Limited to the information it asks for; some collect only limited details	Can be broader, such as financial planning, if that's part of the service
Regulation	Must follow securities laws for SEC- or state-registered advisers	Generally must register with the SEC or state securities authorities
Where to check it	Investor.gov and the firm's Form ADV	Investor.gov and the firm's Form ADV

Which Costs Less: A Robo-Advisor or a Financial Adviser?

The SEC says robo-advisers often seek to offer investment advice for lower costs and fees than traditional advisory programs. With a human investment adviser, Investor.gov says the fee for advice is typically based on the value of all the assets in your account, and you may pay other fees and costs for servicing the account.

Don't stop at the advisory fee. The SEC's robo-adviser bulletin warns that the investments a robo-adviser picks can carry their own costs, so a low advisory fee doesn't guarantee a low total cost. Ask any provider, automated or human, to explain all the fees you'll pay.

Small differences add up. In a 2025 SEC investor bulletin example, $100,000 invested for 20 years with a 4% annual return grows to about $208,000 with a 0.25% annual fee, about $198,000 with a 0.50% fee and about $179,000 with a 1.00% fee. Those rates are for illustration only, not quotes from any provider. You can run your own numbers in our adviser fee calculator, and our guide to how much a financial adviser costs explains the common fee types.

What Are the Limits of a Robo-Advisor?

The biggest limit is what the program knows about you. The SEC says a robo-adviser's recommendation is limited by the information it requests and receives from you, and that some robo-advisers may obtain and consider only limited information. If it doesn't ask about your debts, savings or other assets, its portfolio may not account for them. Keeping your answers up to date often falls to you.

A 2015 joint alert from the SEC and FINRA on automated investment tools adds a few more cautions:

• A tool may rely on assumptions that are wrong or don't apply to you.
• It may not assess all of your circumstances.
• Its output depends directly on what it asks and what you tell it.
• It may be designed to fit you into a set of predetermined options, or consider only investments offered by an affiliated firm.

The same alert says to be wary of tools that promise better portfolio performance.

When Might a Human Adviser Make More Sense?

Neither option is right for everyone. These questions can help you decide:

• How complicated is your situation? If you want advice that weighs several accounts, debts or goals together, check whether a robo-advisor asks about them. A human adviser who offers financial planning may cover more.
• Do you want to talk to someone? If you'd like a person to call when markets drop or life changes, confirm what human access a robo-advisor offers before you sign up.
• What will you pay in total? Compare the advisory fee and the cost of the underlying investments for each option.
• Do you mostly want a managed portfolio? If you're comfortable answering a questionnaire and letting software handle the investing, a robo-advisor may be enough.

What Should You Ask Before Choosing Either One?

The SEC suggests asking a robo-adviser how it handles risk tolerance, how often it rebalances accounts, what fees apply and whether it has conflicts of interest. For automated tools, the SEC and FINRA also suggest asking whether the sponsor receives any form of compensation for recommending services or investments. For a human adviser, Investor.gov suggests asking for the firm's latest Form ADV, including the brochure, and about its hourly rate, flat fee or commissions.

The SEC and FINRA's tips for any automated tool also apply here:

1. Read the terms and conditions, including fees, how to end the service and how long it takes to cash out.
2. Understand the tool's methods and key assumptions.
3. Make sure you understand each question and answer it accurately.
4. Remember that the tool's output may not be right for your needs or goals.
5. Protect your personal information and know how it may be shared.

How Do You Check a Robo-Advisor or Adviser?

Robo-advisers must file Form ADV, just like other registered investment advisers, and you can read the firm's Form ADV Part 1 and Part 2 brochure to learn about its services, approach to investing and features. The SEC's Investment Adviser Public Disclosure database shows registration and any disciplinary history. Our step-by-step guide to checking a financial adviser walks through the free searches.

The Bottom Line

A robo-advisor automates the investing: a questionnaire in, a managed portfolio out, often at a lower cost. A human adviser offers ongoing advice from a person and may cover broader planning. Whichever you lean toward, ask for every fee, find out what information the advice is based on and check the firm's registration before you hand over money. If you're also choosing what to invest in, our guide to mutual funds vs. index funds explains two common building blocks.

Frequently asked questions

What is a robo-advisor?

The SEC describes a robo-adviser as an automated digital investment advisory program. It typically collects information through an online questionnaire, then creates and manages an investment portfolio for you based on your answers.

Are robo-advisors cheaper than financial advisers?

Often, but not always. The SEC says robo-advisers often seek to offer investment advice for lower costs and fees than traditional advisory programs. Your total cost also includes the expenses of the funds in your portfolio, so ask for every fee before you compare.

Are robo-advisors regulated?

Yes. The SEC says robo-advisers in the U.S. must comply with the securities laws that apply to SEC- or state-registered investment advisers. You can look up a robo-adviser's registration and disciplinary history the same way you would a human adviser's.

Can I talk to a person if I use a robo-advisor?

It depends on the service. The SEC notes that some robo-advisers give you access to an investment professional, while others offer only technical support. Ask before you open an account.

Are robo-advisors worth it?

It depends on what you need. If you mainly want a low-cost portfolio managed for you, a robo-advisor may fit. If your situation involves several accounts, debts or goals you want someone to weigh together, check whether the robo-advisor considers that information, or whether a human adviser would serve you better.
