Well, let's start by ignoring Personal Capital, and ask the important question.
Do you need an advisor's help? Most Mustachians assume no. Some people do need that help. Managing a large portfolio can be intimidating for some. Some people can't handle the risk on their own, and having an advisor to talk to can help them avoid costly mistakes. You could have a complicated situation, especially from a tax perspective. If your portfolio includes a taxable account and you don't understand tax efficiency, what cost basis to use, tax loss harvesting, etc. then a 'good advisor' could save you more money in taxes then you pay the advisor. Use them until you feel comfortable doing it all yourself.
If you answered yes to needing an advisor then the next question is who your advisor should be. Here is an easy first rule. If they contacted you then they aren't worth your time. An advisor who is prospecting via cold calling has free time on their hands, and not enough referrals. They aren't established and they are probably inexperienced. 10 years from now they might be awesome, but right now they are a gamble. If you need an advisor do your own research and find the one that fits you. This will likely require scheduling appointments with a few different advisors so you can comparison shop.
Ask them how they are paid and if they are a fiduciary. If the answer doesn't make sense to you then you should leave. An experienced advisor has had ample opportunities to perfect how they answer these questions so it should be transparent and easy to understand.
What is their investment philosophy? Market timing = bad. Describing their investment philosophy is their chance to wow you, and your chance to make sure it is a good fit. Rule of thumb: Good advisors are goals/behavior driven. Bad advisors(salesmen) are product driven. How much time was spent talking about your goals/risk tolerance/etc. VS time spent talking about the products? This is another area where costs can come up. Index funds and ETFs are normally low cost, and active funds & annuities are expensive.
Ask tons of questions. If anything seems off, even a little, then ask. If something sounds interesting and you want to know more, ask. A good advisor wants questions. They are opportunities to show they know what they are talking about.
Costs: I would say in today's world anything over 0.5% AUM is excessive. If you can find an advisor that will charge a flat fee for the plan that also works. Consider the cost with Personal Capital. They charge 0.89% for a virtual(phone/video) relationship with an advisor. Vanguard charges 0.3% for a virtual relationship with a CFP.
