How Much Money Do I Need to Start Trading Stocks?

How much money do I need to start trading stocks? If you've been holding off because you assume it takes thousands of dollars, you're not alone. The real number is usually smaller, but the answer changes with how you plan to trade.

It depends on how you trade, but there's no one set amount. Where fractional shares are offered, you can start with $100 or less, subject to your broker's minimums. Day trading and borrowing through margin come with extra rules and bigger risks. Only use money you can afford to lose.

Educational only. Not financial advice. Here's how we research our guides.

Your starting amount mostly depends on what you mean by "trading":

• Buying with your own cash and holding: a small amount can work if your broker offers fractional shares. Otherwise, you need the price of one share.
• Trading often with your own cash: there's no special amount, but costs bite harder on a small account.
• Day trading or borrowing on margin: extra rules apply, your broker's requirements matter most, and losses can be larger.

If you're also weighing crypto, our crypto for beginners guide walks through that side.

Yes, $100 can be enough if your broker offers fractional shares. A fractional share means you own less than one full share. The SEC's bulletin on fractional shares gives this example: if a stock trades at $1,000 and you have $100, you could buy 0.1 shares.

The bulletin also lists catches to ask your broker about:

• Not every firm offers fractional shares, and some limit which stocks and funds qualify.
• Some firms set minimum order sizes or allow only certain order types.
• You may not have voting rights on a fractional share.

So $100 can get you started, but it can still lose value, especially if it's all in one company.

It's harder because small costs add up quickly against a small balance. One of those costs is the spread, the gap between the buying and selling price.

Made-up example, with a bid of $10.00 and an ask of $10.05:

• You buy 9 shares at $10.05, which costs $90.45.
• The prices don't move, and you sell at $10.00, which brings in $90.00.
• You're down $0.45, though nothing changed.

Repeat that 20 times and $9.00 is gone, about 10% of the $90 you started with. See also why you can lose money in stocks even when the price goes up.

The answer depends on your brokerage firm right now, because the rule is changing. For years, FINRA rules required anyone labeled a "pattern day trader" to keep at least $25,000 in a margin account. That label generally applied to four or more day trades within five business days.

The SEC's pattern day trader page says FINRA has adopted new intraday margin requirements to replace those rules. They took effect June 4, 2026, but firms that need more time have until October 20, 2027. Your firm might still be using the old rules, so ask which ones apply to your account.

A rule change doesn't make day trading safer. Investor.gov's day trading page calls it extremely risky and warns of substantial losses in a very short time.

Yes, through a margin account, but it isn't a shortcut around having a small balance. Margin means your broker lends you money, with your account as collateral. Investor.gov says this raises your purchasing power but also exposes you to potentially larger losses.

Made-up example: you put in $500 and borrow $500 to buy $1,000 of stock. If the stock falls 30%, it's worth $700. You still owe the $500, so your $500 has shrunk to $200, before interest. Without the loan, the same drop would have left you with $350.

While you're learning, a cash-only account keeps the most you can lose to what you put in.

A good amount is one you could lose without it affecting your bills, and there's no universal number. Before you pick a figure, check these:

• Bills and debt: rent, food and expensive debt come first.
• Emergency savings: keep them out of the market, so a surprise bill doesn't force you to sell at a bad time.
• Your timeline: money you'll need soon has less time to recover from a drop.
• Your reaction to a loss: picture the amount down 30%. If that would keep you up at night, start smaller.

You can also add small amounts on a schedule. Our dollar-cost averaging guide shows the idea with crypto, and the math works the same way. It doesn't prevent losses.

No. A single fund can hold many companies, which is hard to do with a small account buying one stock at a time. Funds can still lose value and charge fees.

Try your plan on paper first. For a month, write down each trade you would have made, your reason and the result, including the spread. It costs nothing and shows how often you'd really trade.

Be careful of anyone promising to grow a small account quickly. Guaranteed returns and pressure to deposit more are classic warning signs, as we explain in 7 crypto scams that target beginners. The same tricks show up on fake stock trading sites.

1. Decide what you mean by trading: holding, trading often or day trading.
2. Cover bills, expensive debt and emergency savings first.
3. Ask your broker about fractional shares, order minimums, fees and which margin rules it uses.
4. Skip margin while you're learning.
5. Try the plan on paper, then start with an amount you could lose.

Can you start trading stocks with no money?
No. You need money in your account to buy shares, though you can practice on paper for free. Be wary of offers to fund you in exchange for an upfront fee or personal details.

Can I start trading stocks with $10?
Possibly, if your broker offers fractional shares and its minimum order is $10 or less. Minimums differ by firm, so check first.

How much money do I need to open a brokerage account?
It depends on the firm and the account type, so check its current terms. Margin accounts can have their own requirements, separate from a basic cash account.

Can you get rich trading stocks with $100?
Nobody can promise that, and we won't. Chasing fast growth usually means taking bigger risks, as our guide on whether you can lose money in crypto shows for that market too.

Do I pay taxes when I trade stocks?
Generally, a profit from selling in a taxable account is a capital gain, and rules differ for losses and holding periods. Check with a tax professional about your situation.
