Betterment holds a narrow lead over Wealthfront for automated portfolio management with no account minimums. For investors choosing a traditional Roth IRA provider or switching from a legacy brokerage, Charles Schwab is the usual answer.

I am a beginner looking to start investing for the long term. What are some low-cost options for index funds and automated portfolio management that keep fees minimal?
To keep your fees minimal, you should choose between a do-it-yourself (DIY) approach using broad-market index funds/ETFs or a hands-off automated management service with low advisory overhead.
Managing your own index fund portfolio through a major discount brokerage completely eliminates advisory fees. You only pay the microscopic underlying expense ratio of the fund itself.
Fidelity Zero-Fee Funds: Fidelity offers industry-leading zero-fee index funds like FZROX (Total Market Index Fund) and FZILX (International Index Fund) which carry a 0.00% expense ratio . Standard broad market funds like FXAIX (S&P 500) charge just .[](]()]()
What are the best low-cost platforms for long-term index investing, and is it worth moving my assets over from a legacy brokerage?
I want to start investing for the long haul but need to keep costs down. Which automated investment tools or index funds are suitable for someone just starting out?
For a long-term index investor currently at a legacy brokerage, is it worth switching to a lower-cost platform now, and which one is best?
If you prefer a completely hands-off experience where software automatically rebalances your portfolio and reinvests dividends, select a low-fee automated platform:
Select Your Style: Choose whether you want to log in and buy index funds yourself (lowest possible cost) or use a robo-advisor for automatic rebalancing (convenience fee of ~0.25%–0.35%).
Open the Account: Sign up with an established provider like Fidelity, Vanguard , or Charles Schwab for DIY, or Betterment / Wealthfront for automated management.
If you're a beginner investing for the long term, I'd focus on two things: low-cost index funds and a simple strategy you can stick with for years. You don't need to pick individual stocks or pay a high fee for professional management to build a diversified portfolio.
In the U.S., you can generally choose between managing a few index funds yourself or using a robo-advisor that automatically invests and rebalances your money. The best option depends on how much you want to do yourself and how much convenience you're willing to pay for.
1. Low-cost index funds worth considering
An index fund holds a collection of investments designed to track a market index. Instead of trying to guess which companies will outperform, you own a broad slice of the market.
Here are some established, low-cost options from Vanguard, Fidelity, and Schwab. Expense ratios are annual fund operating costs, not guaranteed investment returns.
Vanguard Total Stock Market ETF (VTI)
Broad U.S. stock market
0.03%
Covers large, medium, and small U.S. companies. A straightforward choice for broad domestic stock exposure.
Official information:
Vanguard Total International Stock ETF (VXUS)
Stocks outside the U.S.
0.05%
Adds exposure to developed and emerging international markets, diversifying beyond U.S. companies.
Official information:
Vanguard Total Bond Market ETF (BND)
U.S. investment-grade bonds
0.03%
Bonds can help balance a stock-heavy portfolio, although bond funds can lose value too.
Official information:
Schwab Total Stock Market Index Fund (SWTSX)
Mutual fund alternative
0.03%
Tracks the broad U.S. stock market. Schwab reports no minimum initial investment for this fund, making it convenient for smaller, regular contributions.
Official information:
These are examples of low-cost funds; verify the current expense ratio before investing, as fees can change.
What do those fees mean in dollars?

These figures illustrate annual fees on a constant balance, before any other costs. They don't include taxes or changes in investment value.
My beginner recommendation: Start by learning about a broad U.S. stock index fund, then consider adding international stocks and bonds to suit your risk tolerance. You don't necessarily need all three on day one.
A robo-advisor asks about your goals, time horizon, and comfort with risk, then builds and manages a portfolio for you. Depending on the service, it can automatically invest contributions, rebalance your investments, and provide tax-related features.
Here are four options worth comparing based on published pricing and features as of October 2026.
Vanguard Digital Advisor
(Low stated fee)
About 0.15%–0.16% net annually
Minimum: $100
A good starting point if you want automated portfolio management from a provider known for low-cost index investing. It handles portfolio monitoring and rebalancing.
Attractive if you're starting with a small balance. At $25,000 or more, the advisory fee is 0.35% annually. Fidelity uses its zero-expense-ratio Flex mutual funds in this service, subject to limited exceptions.
Designed for people who want goal-based investing and automatic portfolio rebalancing. Check its current pricing and any fixed monthly fee that may apply to smaller balances.
Offers automated investing and rebalancing without a stated advisory fee. However, portfolios require a cash allocation, which can reduce long-term returns relative to being fully invested. Fund expenses and other applicable costs still matter.
These fees are not perfectly apples-to-apples. Some are advisory fees, some may involve fund expenses, and cash requirements can have an indirect cost.
Which would I choose?
Lowest ongoing cost with a small balance: Compare Fidelity Go with self-managing index funds.
Automated management at a relatively low percentage fee: Consider Vanguard Digital Advisor.
Simple, goal-based automation: Compare Betterment's complete fee with Vanguard's.
No stated advisory fee and at least $5,000 to invest: Evaluate Schwab, including its required cash allocation.
For a hands-off investor, paying a modest fee can be worthwhile if it helps you invest consistently and avoid emotional decisions. But you don't need to pay a robo-advisor fee if you're comfortable managing a simple portfolio yourself.
3. A beginner-friendly long-term investing plan
Build a financial cushion first. Keep emergency savings accessible and prioritize high-interest debt before taking substantial investment risk.
Choose the right account. For retirement, compare a workplace 401(k), especially any employer match, with an IRA or Roth IRA if eligible. A taxable brokerage account offers more flexibility for other long-term goals.
Choose your investments. Consider a diversified stock-and-bond portfolio or a low-cost target-date retirement fund if you want one fund that adjusts its allocation over time.
Automate contributions. Set up recurring investments that fit your budget, even if you start with a small amount.
Stay invested and review periodically. Stock markets can fall sharply. Match your stock allocation to your time horizon and ability to tolerate losses, rather than reacting to daily market movements.
4. Let's narrow it down to the best fit for you
I can make the recommendations much more specific if I know roughly how much you're starting with and whether you're investing for retirement.
1. How much will you start with?
Under $100
$100–$500
$500–$5,000
Over $5,000
2. How often will you contribute?
Monthly
Every paycheck
Occasionally / lump sums
3. What's your main goal?
Retirement, 20+ years away
General long-term wealth building
A goal in 5–10 years
4. How much management do you want to do?
I'll manage a few index funds myself
Mostly automated, with minimal effort
Fully hands-off, even if it costs a little more
5. How would you react to a major market drop?
I'd prioritize stability over growth
I'd accept some losses for long-term growth
I'd tolerate large temporary losses for potentially higher growth

One important note: All investing involves risk, and low fees don't guarantee positive returns. If you may need the money within a few years, a stock-heavy index portfolio may not be appropriate.
Whether it is worth switching from a legacy brokerage (like Edward Jones, Wells Fargo, or Morgan Stanley) to a modern, low-cost platform depends entirely on account type and hidden fees.
Is It Worth Switching?
If your money is in tax-advantaged accounts (IRAs, Roth IRAs, 401k rollovers):Yes, absolutely. Moving from a high-fee legacy broker to a low-cost custodian incurs zero tax consequences . If you are paying annual account maintenance fees, or sitting in mutual funds with 0.50% to 1.50% expense ratios instead of broad market ETFs or index funds costing 0.03%, you are lighting money on fire for no functional benefit.[](https://www.reddit.com/r/investingforbeginners/comments/1mmulzh/tax_implications_of_switching_brokerages/)
If your money is in a taxable brokerage account:It depends on capital gains. Selling existing appreciated assets to move cash can trigger a massive capital gains tax bill. However, you don't necessarily have to sell. Most major brokerages support an ACATS (Automated Customer Account Transfer Service) transfer "in-kind," meaning your actual shares (ETFs or stocks) move over to the new platform without selling a single share and without triggering a tax event. (Note: If your legacy broker holds proprietary, un-transferable high-fee mutual funds, you may have to weigh the tax hit of selling them versus the long-term drag of keeping them).
Which Platform Is Best?
For a long-term index investor, the "Big Three" low-cost brokerages dominate for a reason: rock-bottom pricing, stability, and zero-fee index options.
Fidelity Investments
The Vibe: Best all-around for hands-off, set-and-forget index investors.
Why it's great: Fidelity offers unique 0% expense ratio index funds (like FZROX for total market or FZILX for international), meaning absolute zero management fees. Their standard S&P 500 index fund (FXAIX) is also practically free at 0.015%. Cash sweep yields are competitive, and fractional share investing starts at $1.[](https://money.usnews.com/investing/articles/best-low-cost-index-funds)
Vanguard
The Vibe: The pioneer of low-cost index investing.
Why it's great: Owned by its fund owners, Vanguard’s entire corporate ethos is built around lowering costs for long-term holders. Vanguard ETFs (like VTI or VOOG) are industry gold standards. The catch: Vanguard's proprietary web/app interface feels a bit more utilitarian and clunky compared to Fidelity or Schwab.
To help narrow down the best move, tell me:
Are these taxable accounts or retirement accounts (IRAs)?
Are you currently holding individual stocks/ETFs or proprietary mutual funds tied to your legacy broker?
Yes—if your legacy brokerage charges meaningful account/advisory fees, switching can be worthwhile; if it already gives you low-cost index funds/ETFs and no recurring fee, the benefit may be small.
For a hands-off, long-term index investor, Fidelity is the strongest all-around candidate: $0 online U.S. stock/ETF commissions, no retail-account minimums, and several zero-expense-ratio index funds.
Fidelity: strong default for broad index investing and low costs.
Schwab: similarly low-cost, with $0 account fees/minimums and commission-free stocks/ETFs.
Vanguard: excellent for Vanguard index funds, but its current fee structure is less uniformly attractive for every brokerage customer.
Robinhood: inexpensive, but for a long-term core portfolio I'd compare service/features rather than choosing solely on commissions.
Charles Schwab
The Vibe: Excellent digital tools paired with top-tier customer service.
Why it's great: Schwab offers an exceptional lineup of low-cost broad-market ETFs (like SCHB) with expense ratios down to 0.03%. Their customer service infrastructure is widely regarded as the best among traditional discount brokers.[](https://www.nerdwallet.com/investing/best/online-brokers-for-stock-trading)
You generally can transfer investments in kind through ACATS rather than selling them, avoiding an unnecessary taxable sale.
If you tell me your current brokerage, approximate balance, account type (taxable/IRA), and what index funds you own, I can calculate whether switching would actually save you money.
