What you can and cannot invest through a savings account
A regular savings account at a bank is not an investment account, and most banks will not let you buy stocks, bonds, mutual funds, or exchange-traded funds (ETFs) directly from it. Your savings account is designed to hold cash and earn a small amount of interest — typically between 4% and 5% annually right now, depending on the bank. If you want to invest in securities, you need a separate brokerage account or investment account, which is a different product entirely.
That said, some banks do offer investment services alongside savings accounts. If your bank is also a brokerage — or if it partners with one — you may be able to open an investment account through the same institution and link it to your savings account. This makes it easier to move money between the two, but they remain separate accounts with different rules, protections, and tax treatment.
The core limitation is this: your savings account itself cannot hold stocks or bonds. Money sitting in a savings account is FDIC-insured up to $250,000, which protects you if the bank fails. Money in a brokerage account is not FDIC-insured; it is protected by SIPC (Securities Investor Protection Corporation) up to $500,000, but only against broker failure, not market losses.
Key Takeaways
- A savings account cannot directly hold stocks, bonds, or mutual funds — you need a separate brokerage or investment account to buy those.
- Money in a savings account earns interest and is FDIC-insured; money in an investment account is exposed to market risk but can grow faster over time.
- Many banks offer both savings and investment accounts, and you can link them so money moves easily between the two.
- If you want to invest, you will need to open a brokerage account at your bank, at an online broker, or at an investment firm.
How to move money from savings into investments
The process is straightforward once you have both accounts open. You transfer money from your savings account to your brokerage account, then use that money to buy investments. The transfer itself usually takes one to three business days if both accounts are at the same bank, or up to five business days if they are at different institutions.
Most online brokers and banks make this simple: you link your savings account as a funding source, then initiate a transfer from your brokerage dashboard. You can set up recurring transfers if you want to invest a fixed amount each month — a common strategy called dollar-cost averaging. Once the money lands in your brokerage account, it sits as cash until you decide what to buy.
Keep in mind that moving money out of your savings account reduces the amount earning interest. If you have $10,000 in savings and you move $5,000 to invest, only the remaining $5,000 continues to earn that 4% or 5% rate. This is one reason many people keep a smaller emergency fund in savings and invest the rest — the interest on a smaller balance is less important than the potential growth from investing.
Why a savings account alone will not build wealth over time
A savings account earns interest, but that interest is modest. At 5% annually, $10,000 grows to $10,500 in a year. Over ten years, assuming you add nothing more, it becomes roughly $16,289. That is real growth, but it does not keep pace with inflation or with what you might earn from investing in stocks or bonds over the same period.
Historically, the stock market has returned an average of about 10% per year over long periods, though individual years vary widely and losses do happen. A bond fund might return 4% to 6% depending on interest rates and the type of bonds. These are not guarantees — markets go down as well as up — but over decades, investing tends to outpace savings-account interest.
The trade-off is risk. Your savings account balance will never drop. An investment account can lose value in the short term. For money you need within a year or two, a savings account makes sense. For money you will not touch for five, ten, or twenty years, investing is usually the better choice, even though it involves risk.
Types of investments you can buy once you have a brokerage account
Once your money is in a brokerage account, you can buy individual stocks (shares of a single company), bonds (loans you make to companies or governments), mutual funds (baskets of many stocks or bonds managed by a professional), or ETFs (similar to mutual funds but traded like stocks). You can also buy options, futures, or other complex securities, though most beginners start with stocks, bonds, and funds.
For someone new to investing, a low-cost index fund or ETF is often a sensible starting point. An index fund tracks a broad market index like the S&P 500, which means you own a small piece of 500 large U.S. companies. This spreads your risk across many companies rather than betting on one. The fees are typically very low — often under 0.1% per year — which means more of your money stays invested and working for you.
Your brokerage account will also have a cash balance, just like a savings account. Money you have not yet invested sits there earning little or no interest. Some brokerages sweep this cash into a money-market fund or a high-yield savings account automatically, which earns you a bit more, but you should check your broker's policy.
Tax differences between savings and investment accounts
Interest earned in a savings account is taxed as ordinary income at your regular tax rate. If you earn $200 in interest and you are in the 22% tax bracket, you owe about $44 in federal tax on that interest.
Investment accounts have more complex tax rules. If you hold a stock or fund for more than one year and then sell it for a profit, that profit is taxed as a long-term capital gain, which is usually taxed at a lower rate than ordinary income — 0%, 15%, or 20% depending on your income level. If you sell within one year, it is taxed as a short-term capital gain at your regular rate. Dividends from stocks and funds can also be taxed differently depending on whether they are may have access to or non-may have access to.
This tax advantage is one reason investing makes sense for long-term money. You can also use tax-advantaged accounts like a 401(k) or IRA to invest, which offer even better tax treatment. A regular brokerage account does not have these tax breaks, but it also has no contribution limits or withdrawal restrictions.
When to keep money in savings instead of investing
Not all money should be invested. Financial advisors typically recommend keeping three to six months of expenses in an easily accessible savings account as an emergency fund. This money should not be invested because you might need it suddenly, and you cannot predict when the stock market will be up or down.
Money you plan to spend within one to two years should also stay in savings or a money-market account. If you are saving for a car you will buy next year or a vacation in six months, investing that money exposes you to the risk that the market will be down when you need to withdraw it. A savings account guarantees your balance will be there.
Similarly, if you are uncomfortable with the idea of your money losing value in the short term, or if you do not have the time or interest to learn about investing, a high-yield savings account is a reasonable place to keep money. The interest rates are competitive right now, and you avoid the stress and complexity of managing investments.
Opening a brokerage account to start investing
Most banks offer brokerage accounts, and so do online brokers like Fidelity, Schwab, E-Trade, and many others. The process is similar everywhere: you provide your name, address, Social Security number, and employment information. You choose what type of account you want — a regular taxable brokerage account, or a tax-advantaged account like an IRA. You link a bank account to fund it, and you are ready to start.
There are no fees to open a brokerage account at most firms. You only pay when you trade — and many brokers now charge zero commission on stock and ETF trades, meaning you pay nothing to buy or sell. You may pay a small fee for certain mutual funds or for advisory services, but basic investing costs almost nothing to start.
If you already have a savings account at a bank, ask whether they offer brokerage services. If they do, opening an investment account there takes minutes and you can link it directly to your savings account. If they do not, you can open an account at any online broker — the process is just as fast and often simpler.
Frequently Asked Questions
Can I invest money directly from my savings account without opening a separate brokerage account?
No. A savings account cannot hold stocks, bonds, or funds. You must open a brokerage or investment account, transfer money there, and then buy investments. The transfer takes one to five business days depending on whether the accounts are at the same bank.
Will I lose my FDIC insurance if I move money to invest?
Yes. Money in a brokerage account is not FDIC-insured. It is protected by SIPC insurance against broker failure, but not against market losses. This is why you should only invest money you will not need for several years.
What is the minimum amount I need to start investing?
Most brokers have no minimum to open an account. Some index funds or ETFs have minimums of $1 to $100, but many have none. You can start with whatever amount you can afford, even $50 or $100.
Should I invest all my savings or keep some in the savings account?
Keep three to six months of expenses in savings as an emergency fund, plus money you will need within one to two years. Invest money you will not touch for at least five years. This balance protects you if an emergency happens while still giving your long-term money a chance to grow.
Can I move money back from my brokerage account to my savings account?
Yes. You can sell your investments and transfer the cash back to your savings account anytime. The sale takes one to three business days to settle, then the transfer takes another one to five business days. There are no restrictions on moving money between your own accounts.
