A beginner’s guide, with a side-by-side look at Fidelity, Schwab and Robinhood. Details are current as of early November 2026.
There’s a stubborn myth that investing is for people with thousands of dollars to spare. A few years ago, that was partly true: if you wanted a share of a company trading at $300, you needed $300. Today, that barrier is gone. With fractional shares, $50 a month is enough to build a real, diversified portfolio from your phone.
The tricky part isn’t getting started anymore. It’s choosing where to start and what to buy, because the app you pick shapes your costs, your options and even how likely you are to stick with it. This guide walks through how fractional investing works, what to buy with a small budget, and how Fidelity, Schwab and Robinhood compare for someone putting in $50 a month.
This article is for general education, not personalized financial advice. Investing involves risk, including the possible loss of money.
Can $50 a Month Really Make a Difference?
It can, mostly because of time. Small, regular contributions benefit from compounding, which means your earnings start earning their own returns.
Here’s a hypothetical example. If you invest $50 every month and your portfolio grows at an average of 7% a year (an assumption, not a promise, and actual returns will vary year to year), you would end up with roughly:
| Years | You contribute | Approximate value |
|---|---|---|
| 10 | $6,000 | $8,700 |
| 20 | $12,000 | $26,000 |
| 30 | $18,000 | $61,000 |
| 40 | $24,000 | $131,000 |
Notice how most of the growth shows up late. The first ten years feel slow, and the last ten feel dramatic. That’s why the single most valuable thing a beginner can do is start early and keep going, even with a modest amount. You can always raise your contribution later when your income grows.
What Are Fractional Shares?
A fractional share is simply a slice of one share. If a stock costs $400 and you invest $20, you own 0.05 of a share. You still get your proportional part of any price gains, and you receive your proportional part of any dividends.
This matters for small investors in two ways:
- You invest in dollars, not share counts. You tell the app “invest $50,” and it buys whatever fraction that amount covers, down to several decimal places.
- Your whole contribution goes to work. Without fractions, a $50 deposit might sit idle because it can’t buy a whole share of anything you want.
Limits to know about:
- Not every stock or fund is eligible at every broker.
- Fractional orders are often handled differently than whole-share orders. Some brokers only accept market orders for fractions, and execution may happen at set times of day.
- If you later move your account to another broker, fractional shares may not transfer in kind and might have to be sold first. Check the broker’s transfer rules if you think you might switch.
Before You Invest Your First $50
A few quick checks will save you headaches later.
1. Build a small emergency cushion. Money you might need within a few years shouldn’t be in the stock market. Aim for at least a starter emergency fund, even a few hundred dollars, in a high-yield savings account, and grow it toward three to six months of expenses over time.
2. Deal with expensive debt. If you’re carrying credit card balances at 20% or more, paying those down beats almost any investment return you can reasonably expect.
3. Grab any employer match first. If your job offers a 401(k) match, contributing enough to earn it is effectively free money and usually comes before anything in a regular brokerage account.
Once those boxes are checked, you’re ready.
Choose the Right Account Type
There are two main choices for a beginner:
- A Roth or traditional IRA. These are retirement accounts with tax advantages. The 2026 IRA contribution limit is $7,500 for people under 50, and $50 a month ($600 a year) fits comfortably inside it. Roth IRAs have income limits and rules about withdrawals, so check eligibility.
- A regular taxable brokerage account. No contribution limits and you can withdraw anytime, but there are no special tax breaks.
A good rule of thumb: if the money is for retirement, start with an IRA. If you want flexibility for goals in the next five to ten years, use a taxable account. Fidelity, Schwab and Robinhood all offer both.
What Should You Actually Buy?
This is where beginners often go wrong. Fractional shares make it easy to buy slices of individual stocks, and that’s tempting, but with $50 a month, spreading your money thin across a few hot names is risky and rarely smart.
For most beginners, the better move is a broad index fund or ETF. These hold hundreds or thousands of companies in one purchase, so you’re not betting on any single one. Examples of categories (not recommendations for specific products):
- Total U.S. stock market funds, which own nearly every publicly traded U.S. company.
- S&P 500 funds, which hold 500 of the largest U.S. companies.
- Target-date funds, which automatically shift from stocks to bonds as your retirement year approaches. These are a simple one-fund solution.
Watch the expense ratio, the annual fee a fund charges. Broad index funds can cost a few hundredths of a percent, and some are even free. On a small balance the dollar difference seems tiny, but fees compound over decades just like returns do.
If you do enjoy picking individual stocks, a common approach is to keep most of your money, say 80% or more, in index funds, and use a small slice for stocks you like.
The Big Three Compared
All three brokers below charge $0 account minimums and $0 commissions on U.S. stocks and ETFs, and all three support fractional shares. The differences come down to what you can buy in fractions, how much help they give you, and extras.
Fidelity: The Best All-Rounder
Fractional minimum: $1. Eligible investments: thousands of U.S. stocks and ETFs.
Fidelity regularly lands at or near the top of beginner roundups, and it’s easy to see why. You can start with a dollar, buy fractional shares of a wide range of stocks and ETFs, and use Fidelity’s mutual funds, including its “ZERO” index funds that carry no expense ratio at all. It also has deep research tools and educational content, and you can reach customer support by phone around the clock.
Pros:
- Fractional shares across a very wide selection of stocks and ETFs
- Zero-expense-ratio index funds, which are ideal for a small, steady investor
- Strong education, research and customer service
- No account fees or minimums
Watch out for:
- No retirement-account match
- The sheer number of tools and menus can feel overwhelming at first
Best for: Beginners who want one long-term home for their money, with room to grow into more advanced features.
Charles Schwab: Great Support and Low-Cost Funds, but a Narrower Fractional Menu
Fractional minimum: $5 per “Stock Slice.” Eligible investments: stocks in the S&P 500.
Schwab’s fractional program, called Stock Slices, lets you buy a piece of any S&P 500 company for as little as $5, with no commission, and you can build a basket of several stocks at once. It’s a clean way to own a handful of big companies.
The catch is the scope. Stock Slices cover S&P 500 stocks, not ETFs. That matters for a $50-a-month investor, because ETFs are usually the best building blocks. Schwab’s answer is its low-cost index mutual funds, which can be bought in small dollar amounts and carry very low expense ratios. So at Schwab, your $50 would typically go into an index fund rather than into fractional ETFs.
Pros:
- Well regarded for customer service and in-person branch support
- Low-cost index mutual funds that accept small purchases
- Easy multi-stock Stock Slices orders for building a mini portfolio
Watch out for:
- Fractional shares limited to S&P 500 stocks, not ETFs
- The $5 minimum is a bit higher than Fidelity’s and Robinhood’s
- The mobile app is described by some reviewers as less polished
- Confirm whether automatic recurring purchases are available for the specific investment you want before relying on them
Best for: People who value strong support and plan to hold low-cost index funds, or who want to own slices of individual large companies.
Robinhood: The Simplest Experience, With a Unique Retirement Perk
Fractional minimum: $1. Eligible investments: thousands of U.S. stocks and ETFs.
Robinhood built its name on a clean, mobile-first design, and it remains the easiest of the three to pick up. You can buy fractions of stocks and ETFs, set up recurring investments with a dollar amount of your choice, and be up and running in minutes.
Its standout feature for retirement savers is the IRA match. Robinhood adds 1% to eligible contributions in a self-directed IRA, or 3% if you subscribe to Robinhood Gold. You must keep the matched money in the account for at least five years, and Gold members need to stay subscribed for a year to keep the full match.
Here’s the math that matters for you, though. At $50 a month, you’d contribute $600 a year. A 1% match is about $6, and a 3% match is about $18. Gold costs $5 a month, or $60 a year, so the paid Gold tier doesn’t pay for itself on this match at a $50-a-month contribution level. The free 1% match is a nice bonus, but not a reason to pick a platform by itself. (Gold may make sense for other reasons, such as a higher rate on idle cash, but weigh that separately.)
Pros:
- Very easy, intuitive app
- Fractional shares of stocks and ETFs from $1, with recurring investing
- Free 1% IRA match on contributions
Watch out for:
- Research and educational tools are thinner than Fidelity or Schwab
- No traditional mutual funds
- Customer support is generally less hands-on than the others
- The app’s design makes it easy to trade impulsively, which isn’t ideal for long-term investors
Best for: Mobile-first beginners who want simplicity and plan to automate a buy-and-hold ETF habit.

What About Other Apps?
A few other names come up often for small investors:
- Public, SoFi and Webull offer commission-free fractional investing and have their own followings. They’re worth a look if you like their interface or specific features.
- Acorns and similar “spare change” apps make investing effortless, but they typically charge a monthly fee, which can take a painful bite out of a small balance. A $3 monthly fee on a $500 account works out to over 7% a year. If you can use a no-fee broker instead, do.
- Robo-advisors build and rebalance a portfolio for you, which is helpful if you want a hands-off approach, though fees vary and some require minimums.
So Which One Should You Pick?
There is no universally correct answer, but here’s a practical way to decide:
- Want the best long-term home and the widest set of options? Choose Fidelity.
- Value in-person or phone support and plan to buy low-cost index funds? Schwab is a strong fit.
- Want the simplest app and a free IRA match? Robinhood works well, especially if you commit to a plain ETF strategy and ignore the trading noise.
If you genuinely can’t decide, Fidelity is the safest default for a $50-a-month beginner, since you can buy both fractional ETFs and zero-fee index funds in one place.
Also remember: you can switch brokers later. The habit of investing every month matters far more than which of these three you start with.
A Simple Step-by-Step Plan
- Pick a broker from the comparison above and open an account. Opening usually takes about 10 minutes and requires your Social Security number and a linked bank account.
- Choose the account type: a Roth IRA for retirement, or a taxable account for flexibility.
- Choose one or two broad funds. A total-market or S&P 500 index fund or ETF is plenty to start.
- Set up an automatic monthly investment of $50, timed for just after payday, so the decision is made once and you don’t have to think about it again.
- Turn on dividend reinvestment so any payouts buy more shares automatically.
- Check in a couple of times a year, not a couple of times a day. Raise your contribution whenever you get a raise.
This approach is called dollar-cost averaging: investing a fixed amount on a schedule regardless of market conditions. You buy more shares when prices are low and fewer when they’re high, and, more importantly, it removes the temptation to time the market.
Common Beginner Mistakes
- Chasing hot stocks. Fractional shares make it easy to throw $10 at whatever is trending. Most beginners are better served by boring, diversified funds.
- Checking the app constantly. Daily price swings are noise. Frequent checking tends to lead to emotional decisions.
- Ignoring fees. Fund expense ratios and monthly app subscriptions matter more on small balances than people expect.
- Stopping when the market drops. Downturns are when regular investors buy at a discount. Staying consistent through them is a big part of long-term success.
- Waiting until you have “enough.” Starting with $50 now beats starting with $500 in two years.
A Note on Safety
Brokerage accounts at SIPC-member firms, which include the major brokers above, are protected by the Securities Investor Protection Corporation if the firm fails, up to $500,000 per customer, including up to $250,000 in cash. That protection covers a broker’s collapse. It does not cover investment losses from the market going down, which is a real risk you take on whenever you buy stocks or funds.
The Bottom Line
You don’t need a lot of money to start investing. You need an account, a plan and the discipline to keep going. Fractional shares have removed the old price barrier, and with fee-free trading at Fidelity, Schwab and Robinhood, your $50 goes to work in full.
Fidelity is the strongest all-around pick for most beginners, Schwab suits support-minded investors who favor index funds, and Robinhood is the slickest app with a modest free IRA bonus. Whichever you choose, keep it simple: a broad, low-cost index fund, an automatic monthly contribution, and patience.
The best time to start was years ago. The second best time is this month.
