Here’s what you should consider:
Management fees. This is what you’ll pay annually to have an account at a robo-advisor.
Expense ratios. These are like management fees, only they’re paid not to the robo-advisor, but to the investments the robo-advisor uses. Mutual funds, index funds and exchange-traded funds all charge this annual fee to cover the costs of running the fund.
Account types. Investment accounts fall into two general categories: Retirement accounts, such as IRAs and 401(k)s, that offer tax advantages while adhering to certain rules; and taxable accounts, where there are no specific tax advantages but also no limits on contributions or distributions.
Investments. Most robo-advisors use low-cost index funds and ETFs.
Rebalancing. Portfolios are fluid, and market fluctuations can cause the mix of investments you hold to get out of sync with your goals. Rebalancing brings that allocation back to its original mix.
Access to human advisors. Many robo-advisors have merged computer-driven portfolio management with access to human financial advisors. Some services offer a dedicated advisor to individual clients; others offer only email or online chat with a team of advisors.
