As robo advisers grow in assets under management, more people are beginning to ask if using one is the right strategy. My last podcast on robo-advisors brought this email from a reader named Steve:

“The other timely podcast was the robo-advisor one. I’m in the process of helping my mom move her accounts from Morgan Stanley over to Vanguard where I’ll be managing them for her. Meanwhile, my IRA and taxable accounts are all at Betterment. It’s always in the back of my mind whether I should be paying the 15 basis points or moving my money to Vanguard. The end of your podcast reassured me a little. I’ll be really interested to hear your follow up podcast. Betterment just makes it so dang easy to automate my deposits into my taxable accounts. I feel like I’m getting more value for the taxable accounts and less for my IRA accounts. The reason being that my IRA is static. I’m not adding to it. It seems like it would be simple enough for me to balance it myself once or twice a year. On the other hand, my taxable investments I automatically invest into every time I get paid. Betterment is able to balance them easily with the new money.”

The biggest issue with robo advisors is cost. Sure, their fees are lower than what you would pay for traditional investment management services. But any fee is significant given the multiplying affects over decades of investing.

For example, an annual robo adviser cost of .25% will reduce an 8% annual rate of return to 7.75%. While that may not make much difference in any single year, it can have a major impact over a period of ten, 20 or 30 years of investing.

Here is a sampling of the costs of four automated investment advisors:

Obviously, the higher the costs, the greater the impact will be on future investment returns.

But that’s not the whole story on robo adviser costs – not by a long shot.  While these services add costs on top of the fees charged by the underlying ETFs, they also provide automated tools that make up for these costs (and in some cases even exceed the costs).

My Epiphany on Robo Adviser Costs

The more research I do on robo advisers, the more I am becoming convinced that cost is not the negative I initially thought it to be.

Whenever we look at costs for anything, we always need to balance it against the benefits that we’re receiving in exchange for those fees. My position is now that the cost associated with robo advisers is actually reasonable.

There are five reasons for my change of thinking on this front…

1. The Cost is Reasonable Compared to the Alternatives

As described above, the costs associated with using a robo advisor do reduce future return on investment.  While the costs are reasonable, in my opinion, we shouldn’t be dismissive of them.  Let’s look at some examples.

We’ll assume an 8% return before robo advisor fees, and a 7.75% return after the fees are taken out.  Over the course of just one year, the results seem insignificant.  A $100,000 investment, for example, would be worth $108,000 a year later at an 8% return (I’m ignoring taxes for now).  With an automated service charging 25 basis points, the return drops to $107,750.  A fee of $250 to let somebody else deal with asset allocation and rebalancing seems like a small price to pay.

But what happens if we multiply this “small” fee over 40 years of investing?  The numbers get really big.  If you do the math, you find that an annual cost of .25% reduces your nest egg over an investment lifetime by enough to buy a home.

For example, if you invest $1,500 per month in a 401(k) (that’s $18,000 per year, which is the 401(k) maximum contribution beginning in 2015) at a rate of 8% per year, you’ll have something approaching $5.2 million after 40 years. But if you reduce your return to 7.75%, after removing the cost of a robo adviser, you’ll end up with something just over $4.8 million.

Thus, while 25 basis points may not seem like a lot, it can add up to about $364,000 over a lifetime of investing.

Now it may sound like I’m arguing against these investing services.  I’m not.  Rather, we just need to dispel any notion that a “small” investment fee doesn’t matter.  All investing fees matter.

With that said, there are two reasons why this fee is reasonable.  First, while the difference may add up to $364,000 over 40 years, in today’s dollars it’s much smaller–roughly $50,000.  That’s still a lot of money, which brings me to the second reason.

Robo advisors offer technology that can increase our returns.  Through automated rebalancing and tax loss harvesting in taxable accounts, services like Betterment and WealthFront can offset these costs.  In some cases, they may even produce excess returns that exceed their fees.

2. Rebalancing

Even for a seasoned DIY investor, rebalancing can be an arduous task. I’ve been doing this for more than 20 years and still find rebalancing to be a pain in the neck.  You can see my approach to rebalancing in Podcast 51 and Podcast 52. Because it can be such a hassle, many investors fail to rebalance their portfolios for extended periods of time.

With computers, however, robo advisers can rebalance your investments more quickly and easily than you can. And because of that, they can do it much more frequently. These services use a trigger based rebalancing approach, which results in rebalancing when an asset class strays from the plan by a set percentage.

At a minimum, rebalancing insures that the risk level of a portfolio remains the same.  Beyond risk, there’s evidence indicating that regular rebalancing improves investment returns. An analysis by Yale University Chief Investment Officer, David Swenson, concluded that rebalancing earns an average of .40% more each year, over 10 years, than portfolios that are not rebalanced.

If that’s the case, then the benefits of automatic rebalancing that robo advisors provide may more than offset an average cost of .25% for using the service.

3. Tax Loss Harvesting

Like rebalancing, tax loss harvesting (TLH) is something that is much better accomplished by computers than it is by individual investors. It’s a strategy in which losing investments are sold in order to create tax losses to offset taxable gains elsewhere.

Should your capital losses exceed your realized capital gains, you can use up to $3,000 of the excess loss to reduce non-investment income. Any losses in excess of $3,000 can be carried forward into future years.

TLH will have no benefit with retirement accounts, since they are tax-deferred. But since TLH at the core is a tax deferral strategy, it can effectively give the benefit of tax-deferral to taxable accounts (by enabling you to defer taxes on capital gains almost continuously).

And again, like rebalancing, TLH may produce increased return on investment. The calculations are complicated, but here are some links that describe the process, as well as the increase in return from TLH indicated by each source:

Though the increase in annual return from TLH varies widely depending upon the source, it’s clear that there is some measurable increase. When an increase in return is combined with the increase in return from rebalancing, it most definitely appears that the tangible improvement in return more than offsets the costs of using robo advisor services.

4. Account Level Asset Allocation

For the person who doesn’t want to be hands-on with his or her investments, the asset allocation provided by robo advisers can be a godsend. And even if you don’t mind creating and managing your own asset allocation strategy, life is just easier when someone else takes care of it for you.

All of this is especially important if you have multiple investment accounts. While creating and maintaining an effective asset allocation can be fairly simple in a single investment account, it becomes geometrically more difficult as the number of accounts that you have increases.

As an example, I currently need to increase my exposure to commodities.  I own a commodity ETF (ticker: DBC) in my SEP IRA (yes, I know it should be in a taxable account; that’s a discussion for another article!).  The problem is that I don’t have the funds in my SEP IRA to buy more of the commodities ETF.  As a result, I’m forced to buy it in a different account if I want to maintain my planned asset allocation.  That presents a host of other problems, including (1) lack of a good commodities fund in my 401k, and (2) selling investments with unrealized gains in my taxable accounts to buy shares of DBC.  Robo Advisors element this problem.

5. Convenience

Finally, it is impossible to overlook the convenience factor as a benefit associated with robo advisers. Since investment activity in a robo adviser account is virtually automatic, you will have that much more time for your non-investment life.

Bonus Reason: Easy Socially Responsible Investing

What if your investments could change the world? Well it won’t happen overnight but, over time, socially responsible investing (SRI) could make a big impact. The purpose of SRI is to invest in companies that support clean energy, healthy living, and social equality. Companies are chosen based on their emphasis on the United Nations’ 17 Sustainable Development Goals.

An easy way to jump on board the SRI train is with Betterment . For as little as $50 you can begin your investment journey with a robo advisor with a strong socially responsible investing focus. Learn more about Betterment here.

Next Steps

I am still exploring Vanguard’s Advisor Service.  For 30 basis points Vanguard will manage your investments for you.  I suspect, however, I’ll end up moving a significant portion of my assets to Betterment and WealthFront.  I plan to use Betterment for my retirement accounts because it has the lowest fees (15 basis points for accounts over $100,000) and use Wealthfront for my taxable accounts because of its excellent TLH tools.

An Alternative to Consider

While I absolutely love robo advisors, I would be remiss to not consider the alternative of active portfolio management. The problem is, finding someone to do it can be expensive and arduous. Plus, you’re trusting an unknown person with your money.

But recently, I’ve learned about a company called Facet Wealth that vets and works with only the best CFPs around. They’re a flat-fee based service and you’ll have a dedicated CFP to work with you on your investment goals. Plus, you don’t even have to leave home to meet with your CFP–you’ll meet them via video conference from the comfort of your home.

Right now I’m loving Facet Wealth–so check out our full review to see if they’re a fit for you.

Robert K says:

Hi, Rob,

I just listened to the latest podcasts and signed up for a Betterment account (via the affiliate link!) for taxable investment, BUT I have some concerns about the standard portfolio and am not sure I am going to pull the trigger.

What I like: The value tilt of the portfolio
What I don’t like: A heavier weighting in international equities than I prefer and the use of international bonds on the fixed income side.

I suppose that I can dilute the effect of the items that I do not like by going 100% equity and having separate accounts for fixed income and for US stocks, but then I lose the benefit of the automated features that make Betterment potentially useful to me.

I checked out Wealthfront and the heavy international weightings and the natural resources positions were deal killers over there.

In short, I am probably back to doing it all myself. 🙁

Best, Robert

Shane H says:

Almost all robo advisors charge a fee for their services, but there are other options. Hedgeable offers a 100% free service called the Basic Program that is virtually identical to what you would get at Betterment or WealthFront. This includes all of the benefits mentioned in the article: rebalancing, continuous tax loss harvesting, asset allocation, convenience, automated contributions for taxable accounts, and more – all at absolutely no cost ($5,000 minimum account size).

However, it is also our view that investors can and should do better than what basic passive portfolios offer. The Hedgeable Plus Program gives you something much more sophisticated at a reasonable price (0.30% – 0.75%). This includes everything in the Basic Program plus downside protection, risk management, dynamic asset allocation, access to both ETFs and stock-based portfolios, and more alternative asset classes. Hedgeable is the first retail asset manager to invest clients directly in bitcoin via an integration with Coinbase, at no additional cost.

While it is true that fees reduce returns over long periods, the added value can more than offset that. For example, missing out on 75% of the losses during the Dot-Com Bust and the 2008 Financial Crisis would have netted the average American over $1 million more for retirement. Passive index investing accepts those losses under the pretense that markets will rebound over the long-term.

Wealthy individuals do not invest with that mindset, and thus do not experience the devastating losses that most Americans do. It is Hedgeable’s goal to democratize the sophisticated kind of investing that the wealthy engage in, making it available to everyone at an affordable cost.

Rob Berger says:

Shane, isn’t your Plus Program just another form of market timing? Do you guarantee better returns after fees and taxes than a passive portfolio?

Shane H says:


The Hedgeable Plus Program is not based on market timing – it’s all reactionary. Our investing systems look at every security and market everyday and dynamically react.

Just as rebalancing can add value, intelligent active management can as well, especially over complete market cycles. There is no reason to invest in markets when they are significantly declining. High-net-worth people don’t do it, and you shouldn’t either.

As you might guess, we cannot guarantee anything. But we can show you why we think our investment philosophy has merit, and how we intend to improve the lives of millions of Americans.

Andrew Tannenbaum says:

“The Hedgeable Plus Program is not based on market timing – it’s all reactionary.”

That IS market timing.

Rob Berger says:

I don’t see the difference between market timing and “reactionary”.

Eric says:

To make sure I understand your math in Part 1, if the difference of 25 basis points is $364K (or the future value), isn’t the present value closer to $15K, not $50K? [$364K / (1+.08)^40]

Rob Berger says:

Eric, I used a different discount rate. Your point is a good one. The discount rate makes a huge difference!

Mary says:

I’m slowly starting to think that I might be served by at least putting some of my investments in the hands of the robo-advisors. However, I’m waiting for a little bit longer for this one reason: the upcoming Schwab Intelligent Portfolios with fees of ZERO bps. http://pressroom.aboutschwab.com/press-release/corporate-and-financial-news/schwab-announces-planned-launch-schwab-intelligent-portfo

Of course, the devil is in the details, but I’m very curious to see how this shakes out.

Rob Berger says:

Mary, I’m very curious, too. One thing to watch for are the specific investments they will use, which presumably will be Schwab ETFs. Schwab’s index ETFs tend to start at about 32 basis points and go up. So even if the new service is free, total costs could be the same as compared to a Betterment or WealthFront.

Chris B. says:

I know I’m super late on this one but was wondering if you ever decided to put your money into any of these?

The Schwab one is really tempting, but they put a larger amount of the account into Cash than the others, and they don’t offer some feature like tax loss harvesting. Still though, they know what they’re doing and I bet they’re seeing pretty good results either way.
