If you're worried about your financial future and are interested in low-fee investment management help, there's likely a robo-advisor or computerized financial advisor that’s right for you.

Here's a minimized list of available robo-providers—a manageable few that you can sort through based on what type of service you're looking for—as well as what you need to do before selecting one.

Jot Down What You're Looking For

Before deciding upon the right robo-advisor, consider your answers to these questions:

  • How much money do you have to invest? Each robo-advisor has its own minimum investment amounts. A few have low entry thresholds of $100 or less. Others require much greater amounts of investable assets. The answer to this question will automatically winnow down your choices.
  • Are there certain asset classes you want included in your investment portfolio? The number of available investment choices varies by robo-advisor. If investing in a real estate investment trust (REIT) or a diverse number of bond ETFs is crucial for you, then certain robos will meet your needs better than others. Although most have a fixed number of ETFs or mutual funds, there are other robos with access to groups of stocks.
  • Do you want access to a human financial advisor as well? If it’s important for you to talk to a real person on occasion, then you may want a robo-advisor with access to a financial professional.

Although the robo-advisors in general tend to get lumped together as a whole, there are many differences with each one. Here are some more guidelines to help you find the right service. (For more, see: Can You Really Trust a Robo-Advisor?)

You Want Even More

Most robo-advisors will give you a diversified portfolio of stock, bonds and international ETFs. If you’re looking for more, then you may want to check out these:
