Robo-Advisors vs Buying ETFs Directly: Which Is Better?

The Complete Answer

A robo-advisor (Betterment, Wealthfront, Schwab Intelligent Portfolios) builds and manages a diversified ETF portfolio for you automatically — choosing the funds, rebalancing, and often harvesting tax losses — in exchange for a management fee, typically about 0.25% a year on top of the underlying ETF fees. Buying ETFs directly skips that fee but puts the work on you.

The math is straightforward. On a $10,000 balance a 0.25% robo fee is about $25 a year; on $100,000 it is $250. Buying VTI, VXUS, and BND yourself costs essentially nothing beyond their ~0.03-0.08% expense ratios. Over decades that fee difference compounds into real money — but only if you actually do the maintenance the robo would have handled.

Robos earn their fee mainly through behavior and automation. They keep you diversified, rebalance without you forgetting, and discourage panic selling. For many beginners, "set it and never touch it" is genuinely worth 0.25%, because the biggest risk to a DIY investor is not fund selection — it is inertia and emotion.

A reasonable path: if you will reliably automate contributions and rebalance once a year, buy three broad ETFs directly and pocket the savings. If you know you will procrastinate or get nervous in a downturn, a robo's hand-holding is cheap insurance. Many people start with a robo to build the habit, then move to DIY once they are comfortable.
