With today’s digital innovations, investors are no longer limited to the brick-and-mortar brokerage firms that their parents used.
Instead, online brokers have enabled investors to go outside the boundaries of traditional trading institutions. By circumventing the proverbial middle man, individual investors can start investing in the stock market all on their own.
But how do you find the best online brokerage firm? And should you tackle investing alone?
They’re important questions, and the answers to them will determine which is the best online broker for you.
What Is a Brokerage Account and Can I Use It to Buy Stocks?
A brokerage account, including many of the apps that allow you to set up accounts, are investment accounts that allow you to invest in the stock market. The returns your investments generate are a form of taxable income. Yes, that’s right — you will be taxed on any income you earn from online stock trading.
The way it works is simple. Start by opening and funding an account with a cash deposit or ACH transfer. After your deposit funds clear, you can immediately begin purchasing stocks. Many online brokers will charge you a fee to make trades, even if you are purchasing for the first time.
You can then monitor the stocks you’ve purchased until you are ready to sell. If you choose to sell, you’ll have the option to keep the funds in your brokerage account [for future purchases], or you can transfer the balance back into your primary funding account.
How to Find the Best Online Broker for You
Learning how to start investing, especially if you’re a total beginner, can be overwhelming. Taking your money and investing it into the stock market is something a majority of people haven’t done on their own. Complicating things further is the fact that you’ll be responsible for preventing mistakes, doing your own research, and avoiding trading-oriented fees.
Then again, there’s the legitimate appeal of not having to pay a steep management fee for someone to invest your money.
For investors looking to buy and sell stocks, there are many online brokers to choose from. Depending on what your specific needs are, a broker that’s a great fit for someone else might not be the best choice for you.
The DollarSprout team has spent dozens of hours compiling research on all of the top brokers. We’ve sifted through each company’s pricing models, functionalities, online reviews, and more, and came up with a list of what we feel are the best online brokerages for stock trading.
Below are the highlights of our findings, along with links to more in-depth reviews and additional resources.

What should you look for in an online broker?
Here are some questions you should always ask before deciding on an online brokerage for investing:
What are the account minimums?
Most brokers will allow you to start small, but be sure to check the account minimums to ensure you qualify.
Do the tools fit my needs?
If you need access to high-end tools for research and active trading, a platform designed for beginners won’t be right for you.
How much do trades cost?
This is especially important for smaller accounts and for people who trade often. Fees will always eat into your returns, so this is an important consideration.
How is the customer service?
Helpful customer service will never go out of style.
What About Online Investment Apps?
If you want to go further than just exploring the best online brokerages, and would like to explore an area where younger investors are flocking to, check out our research on the best investment apps.
At a glance:
- Acorns – Best overall
- Stash – Best for values-based investing
- Betterment – Best investing app for long term investors
- M1 Finance – Best commission free investing app
- Ally Invest – Best app for do-it-yourself investors
- Fundrise – Best real estate investment app
- Stockpile – Best for buying fractional shares
- Robinhood – Best for options and crypto trading
Each of these apps and services are specialized and meet the needs of a different kind of trader.
To get started with one, you’ll need a well-balanced investing strategy; one that considers your entire financial outlook.
If you do not have a sound fiscal budget in place, an area where many younger, inexperienced investors struggle, you’ll end up pouring too much money into rigid investment accounts (with penalized withdrawals), instead of servicing high interest debt or paying essential bills.
Some investors may find Betterment a great option because the app is a better fit for long term investment strategies. Patience is the name of the game here, and the robo-advisor is the best in the industry for long term investors.
Other investors, such as those who are looking to invest and utilize option and cryptocurrency trading, may prefer Robinhood. This commission-free, high tech app has all the bells and whistles needed to get started in the crypto and options markets.
Getting Started is the Most Important Step
If this is your first time investing, not to worry. With so many trading platforms available, including ones that require no minimum balance and no trading fees, you can learn on your own and use our resources to guide you every step of the way.
Investing with an online broker, even one of the best online brokers, doesn’t guarantee anything — the stock market is not an exact science. Instead, the stock market sways and shifts every single day and is deeply impacted by a myriad of factors that range from everything between politics, news, weather, and the actions of other traders.
The more time your investments must mature, the more money you will end up having in retirement. That means that the best time to start is now, even if you start small. The rise of mobile has made tracking and growing your money easier than ever.
With any one of the investment apps listed above, it’s easier than ever to get started with investing today.
