Cheapest robo-advisors in 2026 (ranked for low fees)
Robo-advisors can make investing fairly hands-off, especially if you don’t want to manage portfolios yourself. The tricky part is that “low fee” doesn’t always mean what it seems. Advisory charges, ETF expense ratios, and minimum balance rules can quietly change the real cost.
This guide looks at some of the cheapest options in 2026, focusing on total cost, transparency, portfolio design, and how easy they are to actually use day to day. Platforms like Betterment, Wealthfront, Schwab Intelligent Portfolios, along with newer low-cost options like SoFi and M1 Finance, all show up here.

How the selection was made
The focus here is on total cost rather than just the headline advisory fee. That includes:
- Advisory fees plus fund expense ratios
- Minimum deposit requirements
- Tax-loss harvesting features
- Portfolio diversification
- Automation quality (rebalancing, goal tracking)
- Ease of use
- Fee transparency
A platform that looks free can still cost more once ETF expenses or constraints are included.
