Where Your Money Actually Earns Interest

Interest is paid to you when a bank or financial institution borrows your money. You deposit cash into an account, they lend it out, and they pay you a percentage of what you deposited as compensation. The rate they pay depends on the account type, the bank, current economic conditions, and how long you agree to leave the money untouched.

The most common places to earn interest are savings accounts, money market accounts, certificates of deposit (CDs), and bonds. Each one pays a different rate and has different rules about when you can withdraw your money without penalty. The trade-off is simple: the longer you lock your money away or the less access you have to it, the higher the interest rate usually is.

Right now, interest rates are higher than they have been in years, which means the money sitting in your account can actually work for you. But rates change, and different banks pay very different amounts for the same type of account. Shopping around matters.

Key Takeaways

  • High-yield savings accounts currently pay 4% to 5% annual interest, compared to 0.01% at many traditional banks, so moving your money can add hundreds of dollars per year with no extra work.
  • Certificates of deposit (CDs) lock your money for a set period—usually three months to five years—and pay higher rates the longer you commit, but you pay a penalty if you withdraw early.
  • Money market accounts combine features of savings and checking accounts, often with higher interest rates than regular savings, but usually require a larger opening deposit.
  • Interest rates change constantly, so the best account today may not be the best next month; check rates at multiple banks before moving your money.
  • Interest earned in a savings account is taxable income, so you will receive a 1099-INT form at tax time if you earn $10 or more in interest during the year.

High-Yield Savings Accounts: The Easiest Starting Point

A high-yield savings account is a regular savings account that pays significantly more interest than a traditional bank account. As of now, high-yield accounts pay between 4% and 5% annually, while many brick-and-mortar banks pay 0.01% or less. That difference means $10,000 in a high-yield account earns $400 to $500 per year, while the same amount in a traditional account earns just $1.

High-yield accounts are offered by online banks and some credit unions. They work exactly like a regular savings account—you deposit money, watch it grow, and withdraw whenever you need it. There are no penalties for taking your money out, though some banks limit how many withdrawals you can make per month (though this rule is less common now). The catch is that rates are variable, meaning the bank can lower the rate at any time, though they rarely do so suddenly.

To open one, you need a Social Security number, proof of identity, and an initial deposit (usually $0 to $25, depending on the bank). Popular options include Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank, but rates and features vary, so compare a few before choosing. You can move money between your high-yield account and a checking account at the same bank instantly, or transfer to accounts at other banks in one to three business days.

Certificates of Deposit: Higher Rates for Locked-In Money

A certificate of deposit (CD) is an agreement where you give a bank your money for a fixed period—three months, six months, one year, three years, or five years—and they pay you a set interest rate for the entire term. In exchange for locking your money away, CDs currently pay 4.5% to 5.5% annually, which is higher than high-yield savings accounts.

The trade-off is access. If you withdraw your money before the CD matures (reaches its end date), you pay an early withdrawal penalty. The penalty is usually three to six months of interest, though it varies by bank and CD term. A one-year CD might cost you $50 in penalties if you pull the money out after six months; a five-year CD might cost you several hundred dollars. You need to be confident you will not need the money for the full term.

CDs are useful if you have money you know you will not touch—a tax refund, a bonus, money you are saving for something specific that is still months away. You can also build a CD ladder by buying multiple CDs with different maturity dates. For example, you might buy five one-year CDs, each maturing in a different month. As each one matures, you can withdraw the money or roll it into a new CD at whatever the current rate is. This strategy gives you regular access to portions of your money while keeping most of it locked in at higher rates.

Money Market Accounts: A Middle Ground

A money market account combines features of a savings account and a checking account. It typically pays higher interest than a regular savings account (currently 4% to 5%), allows you to write checks or use a debit card, and lets you withdraw money whenever you want without penalty. The trade-off is that most money market accounts require a larger opening deposit—often $2,500 to $10,000—and may charge monthly fees if your balance drops below a minimum.

Money market accounts make sense if you want higher interest than a regular savings account but need more flexibility than a CD offers. They are less common than high-yield savings accounts, and rates vary widely between banks. Some credit unions offer competitive money market rates, so it is worth checking both online banks and your local credit union.

Bonds and Treasury Securities: Longer-Term Options

Bonds are loans you make to a government or corporation. You give them money, they pay you interest over time, and at the end of the bond's term, they return your principal. Treasury securities are bonds issued by the U.S. government and are considered very safe because the government backs them. Treasury bills mature in less than a year, Treasury notes mature in two to ten years, and Treasury bonds mature in 20 to 30 years. The longer the term, the higher the interest rate.

You can buy Treasury securities directly from the U.S. Department of the Treasury through TreasuryDirect.gov with no fees, or through a bank or brokerage (which may charge a small fee). Interest rates on Treasuries change daily based on market conditions. Right now, a one-year Treasury bill pays around 5%, while a ten-year Treasury note pays around 4%. The interest is taxable at the federal level but exempt from state and local taxes.

Bonds are less liquid than savings accounts—if you need your money before the bond matures, you have to sell it on the secondary market, and you might get less than you paid if interest rates have risen. For most people saving for the short term (under five years), a high-yield savings account or CD is simpler and more practical than bonds.

How Interest Rates Are Set and Why They Change

Banks set their own interest rates, but they are influenced by the federal funds rate, which is the interest rate the Federal Reserve charges banks when they borrow from each other. When the Fed raises its rate, banks typically raise the rates they pay on savings accounts and CDs. When the Fed lowers its rate, banks usually lower what they pay you. The Fed changes its rate based on inflation, employment, and economic growth.

This means the interest rate you see today may not be the rate you get next month. High-yield savings accounts have variable rates, so the bank can change them anytime (though they usually give you notice). CDs have fixed rates, so once you lock in a rate, it does not change for the life of the CD. If rates rise after you buy a CD, you are stuck with the lower rate. If rates fall, you benefit from having locked in the higher rate.

Checking rates across banks is important because even small differences add up. A 4.5% account earns $450 per year on $10,000, while a 5% account earns $500—a $50 difference for doing nothing but moving your money. Over five years, that is $250 in extra interest.

What Happens to Interest at Tax Time

Interest you earn is taxable income. If you earn $10 or more in interest during the calendar year, the bank will send you a Form 1099-INT by January 31 of the following year. You report this interest on your tax return, and you owe federal income tax on it at your regular tax rate. Some states also tax interest income.

This means a high-yield savings account earning $500 per year will add $500 to your taxable income. If you are in the 22% tax bracket, you will owe about $110 in federal tax on that interest. The interest is still worth earning—you are still ahead—but it is not quite $500 of assistance programs.

One exception: interest earned in a Roth IRA or traditional IRA is not taxed as it grows, though withdrawals from traditional IRAs are taxed as income. If you have money you are saving for retirement, putting it in an IRA and earning interest there is more tax-efficient than earning interest in a regular savings account.

Frequently Asked Questions

How much money do I need to start earning interest?

Most high-yield savings accounts require $0 to $25 to open. Money market accounts typically require $2,500 to $10,000. CDs usually have no minimum, though some banks require $500 or $1,000. Treasury securities can be bought in amounts as small as $100. Start with whatever you have; even small amounts earn interest.

Is my money safe in a high-yield savings account?

Yes, if the bank is FDIC-insured. The Federal Deposit Insurance Corporation protects up to $250,000 per account holder per bank. Check the bank's website or call to confirm FDIC insurance. Online banks are just as safe as traditional banks as long as they carry this insurance.

Can I move my money out of a CD early without losing money?

You can withdraw early, but you will pay an early withdrawal penalty, usually three to six months of interest. For example, if your CD pays $100 in interest and the penalty is three months, you lose $25. Some banks offer no-penalty CDs that let you withdraw without penalty, but they pay lower interest rates.

What is the difference between a high-yield savings account and a money market account?

High-yield savings accounts usually have lower opening deposits, no monthly fees, and simpler features. Money market accounts often require larger deposits and may charge fees, but they give you check-writing and debit card access. Both pay similar interest rates; choose based on whether you need checking features.

Should I put all my money in the highest-paying account?

Not necessarily. Keep money you need access to in a high-yield savings account. Lock away money you will not touch for months or years in a CD or Treasury security to earn a slightly higher rate. Diversifying across account types reduces the risk that you will need money and have to pay a penalty to access it.
