I thought it was interesting that roboadvisors like Wealthfront also charge a percentage of assets, instead of a flat fee.  I have Vanguard funds already, and the free tier of Wealthfront.  If Wealthfront seems to be doing a better job, I would be tempted to just echo their  portfolio balance in my larger account, rather than paying them to do it.<p>Given how much fees can affect returns, I might pay for Wealthfront&#x27;s services, but I wouldn&#x27;t pay a lot, and &quot;$250&#x2F;year per $100k&quot; seems like too much.
