Checking accounts earn almost nothing; mutual funds can earn significantly more, but with risk you don't take with a checking account

A checking account at a bank or credit union typically earns between 0.01% and 0.50% annual interest, depending on the institution and account type. A mutual fund — a pool of money invested in stocks, bonds, or other securities — has no may provide return, but historically has averaged 7% to 10% per year for stock-based funds over long periods. The trade-off is real: your checking account money is safe and available tomorrow; mutual fund money can lose value in the short term and is meant to stay invested for years.

The choice between them is not actually about which earns more. It is about what the money is for. A checking account holds money you need to spend soon. A mutual fund holds money you will not need for years and can afford to risk.

Key Takeaways

  • Checking accounts earn 0.01% to 0.50% per year; mutual funds historically average 7% to 10% per year for stock funds, but returns are not may provide.
  • Checking account interest is fixed and safe; mutual fund returns fluctuate daily and can be negative in any given year or month.
  • Money in a checking account is insured by the FDIC up to $250,000; mutual fund investments are not insured against loss.
  • Checking accounts are for money you need within months; mutual funds are for money you can leave untouched for five years or longer.
  • Many people use both: a checking account for living expenses and a mutual fund for long-term savings or retirement.

Why checking account interest is so low

Banks pay checking account interest from the money they lend out — mortgages, car loans, business loans. When interest rates are low, banks lend at lower rates, so they pay depositors less. When the Federal Reserve raised rates starting in 2022, some checking accounts began paying 0.40% to 0.50%, which was unusual. Most checking accounts still pay 0.01% to 0.05%.

The real purpose of a checking account is not to earn money. It is to hold money safely, keep it accessible, and let you pay bills and withdraw cash. The interest, when it exists, is a small bonus. If you put $10,000 in a checking account earning 0.05%, you earn $5 per year.

How mutual fund returns work and why they vary

A mutual fund pools money from many investors and buys a basket of securities — usually stocks, bonds, or a mix. The fund's value rises or falls based on what those securities are worth on any given day. If you own shares in a stock mutual fund and the stock market drops 20% in a year, your fund drops roughly 20% too. If the market rises 15%, your fund rises roughly 15%.

Historical data shows stock mutual funds have returned an average of about 10% per year over the past 50 years, but that average hides huge year-to-year swings. In 2022, many stock funds lost 15% to 20%. In 2023, they gained 20% to 30%. A bond mutual fund is less volatile but typically returns 3% to 5% per year. A balanced fund mixing stocks and bonds might return 6% to 8% on average.

These are historical averages, not promises. Past performance does not predict future results. A mutual fund could underperform for a decade or outperform for a decade. You could need the money during a down year and be forced to sell at a loss.

The safety difference: FDIC insurance versus market risk

Money in a checking account is insured by the Federal Deposit Insurance Corporation (FDIC) up to $250,000 per depositor per bank. If the bank fails, you get your money back. If you have $50,000 in a checking account earning 0.05%, you will have $50,000 plus interest when you need it.

Money in a mutual fund is not insured. If you invest $50,000 in a stock mutual fund and the market crashes, your $50,000 could become $40,000 or $30,000. The fund company does not owe you the original amount. You own shares of the fund, and those shares are worth whatever the market says they are worth on the day you sell.

This is why mutual funds are not suitable for money you might need in the next year or two. If you invest $50,000 for a down payment on a house and the market drops 25% six months later, you have lost $12,500. A checking account would have earned you $20 in interest instead, but you would still have $50,000.

When to use a checking account versus a mutual fund

Use a checking account for money you will spend within the next 12 months: rent, utilities, groceries, car payments, insurance, emergency cash. The interest is negligible, but the safety and access are essential. If you have $5,000 in an emergency fund, it belongs in a checking or savings account, not a mutual fund.

Use a mutual fund for money you will not need for at least five years and ideally longer. This includes retirement savings, money for a child's college fund years away, or long-term wealth building. Over a five-year or ten-year horizon, the higher average returns of a mutual fund outweigh the short-term volatility.

Many people use both. They keep three to six months of expenses in a checking or savings account, and invest additional savings in mutual funds through a retirement account like a 401(k) or IRA, or through a taxable brokerage account.

The cost of choosing wrong

If you put money meant for short-term spending into a mutual fund, you risk needing it during a market downturn and having to sell at a loss. If you put money meant for long-term growth into a checking account earning 0.05%, you lose the compounding power of higher returns over decades.

A concrete example: $10,000 invested in a checking account earning 0.05% for 30 years becomes $10,150. The same $10,000 in a mutual fund averaging 8% per year becomes $100,627. That is the difference between a checking account and a mutual fund over a long time horizon. But if you need that $10,000 in two years and the market is down, the mutual fund might be worth $8,500, and you have lost money.

How to compare specific checking accounts and mutual funds

For checking accounts, look at the annual percentage yield (APY) listed on the bank's website. Compare it across banks — some online banks pay 0.40% to 0.50%, while traditional brick-and-mortar banks often pay 0.01%. Also check for monthly fees, minimum balance requirements, and whether you can access your money without penalty.

For mutual funds, look at the fund's prospectus, which lists the fund's objective, holdings, historical returns, and fees. Pay attention to the expense ratio — the annual percentage you pay to own the fund, usually 0.05% to 1.00% depending on the fund type. A lower expense ratio means more of your money stays invested. Also note whether the fund is actively managed (a manager picks stocks) or passively managed (it tracks an index like the S&P 500). Passive funds usually have lower fees.

Frequently Asked Questions

Can I earn more in a savings account than a checking account?

Yes, often by a small amount. High-yield savings accounts at online banks currently pay 4% to 5% APY, compared to 0.01% to 0.50% for most checking accounts. The money is still FDIC insured and accessible, but there may be limits on how many withdrawals you can make per month. A high-yield savings account is a middle ground between a checking account and a mutual fund.

What if I invest in a mutual fund through my 401(k) or IRA?

The mutual fund itself works the same way — returns fluctuate, there is no may provide, and you should not need the money for years. The difference is the tax treatment. Money in a 401(k) or traditional IRA grows without being taxed each year, and you do not pay taxes until you withdraw it in retirement. This tax advantage makes long-term mutual fund investing even more powerful for retirement savings.

Is there a type of mutual fund that is safer than stocks?

Bond mutual funds and money market funds are less volatile than stock funds. A bond fund might return 3% to 5% per year with smaller ups and downs. A money market fund is very stable but returns only slightly more than a savings account. These are still not insured like a checking account, but they are less risky than stock funds if you have a medium-term time horizon of three to five years.

What happens to my checking account interest if the bank fails?

The FDIC takes over and pays you up to $250,000 of your balance, including any accrued interest. You do not lose money. This is why checking accounts are considered safe even though the interest is low — the safety is the point, not the earnings.

Can I move money between a checking account and a mutual fund easily?

Yes, but there are tax consequences if the mutual fund is in a taxable account. If you sell mutual fund shares that have gained value, you owe capital gains tax on the profit. If the fund has lost value, you can deduct the loss. Money in a checking account has no tax consequence when you move it. This is another reason to keep short-term money in a checking account and long-term money in mutual funds — you avoid unnecessary tax bills.
