Yes, savings accounts collect interest, but the amount depends on the account type and the bank's rate

A savings account collects interest when the bank pays you a percentage of the money you keep deposited there. The bank uses your deposits to lend to other customers and invests that money; in return, it shares a portion of what it earns with you. The interest rate varies widely — from nearly nothing at some large national banks to rates that change monthly at online banks and credit unions. The rate your account earns is set by the bank, not by you, and it can go up or down without warning.

Interest is usually calculated daily but paid monthly or quarterly. If you have $5,000 in an account earning 4.5% annually, the bank divides that rate by 365 days, calculates what you've earned each day based on your balance, and deposits the total into your account at the end of the month. The longer your money sits there, the more interest accumulates — though the growth is slow at lower balances.

Key Takeaways

  • Most savings accounts at large national banks earn less than 0.5% annually, while online banks and credit unions often pay 4% to 5% or higher.
  • Interest is calculated on your daily balance and usually deposited monthly, so the exact amount you earn depends on how much you keep in the account and for how long.
  • High-yield savings accounts (HYSAs) at online banks are the fastest way to compare rates, since they publish rates publicly and change them frequently.
  • The interest you earn is taxable income and will be reported to you on a Form 1099-INT if you earn $10 or more in a year.

Why interest rates vary so much between banks

Large national banks like Chase, Bank of America, and Wells Fargo typically offer savings rates between 0.01% and 0.5% annually. These banks have high overhead costs — physical branches, staff, advertising — and they don't need to offer competitive rates because many customers stay for convenience rather than returns.

Online banks like Marcus, Ally, and Wealthfront have no physical branches, lower operating costs, and compete directly on rate. They often offer 4% to 5.35% annually on standard savings accounts. Credit unions, which are member-owned nonprofits, also tend to pay higher rates than national banks. The trade-off is that online banks and credit unions may have slower customer service or fewer features, though most offer the same federal deposit insurance as traditional banks.

How much interest you'll actually earn

The difference between a 0.1% rate and a 4.5% rate is dramatic. On $10,000 saved for one year, you'd earn roughly $10 at 0.1% but $450 at 4.5%. Over five years, that gap grows to $50 versus $2,432 — assuming rates stay the same and you don't add or withdraw money.

Interest compounds, meaning you earn interest on the interest you've already earned, but the effect is small in savings accounts. On $10,000 at 4.5% annually, compounding monthly adds only about $23 more per year than simple interest would. The real money comes from keeping a larger balance in the account for longer and choosing a bank with a higher rate.

When interest rates change and how to track yours

Banks can raise or lower their savings rates at any time without notice. When the Federal Reserve raises its benchmark interest rate, online banks and credit unions usually raise their savings rates within days or weeks. When the Fed cuts rates, banks drop theirs just as quickly. You won't see a notification — you have to check your bank's website or log into your account to see the current rate.

If you opened a high-yield savings account at 5% and rates drop to 3%, your rate drops with it. This is why it's worth checking rates every few months if you have a large balance. Some people move money between banks to chase the highest rate, though the effort is only worthwhile if you have $25,000 or more saved.

How interest is taxed

Interest earned in a savings account is ordinary income and is taxed at your regular tax rate. If you earn $100 in interest and you're in the 22% tax bracket, you owe roughly $22 in federal income tax on that interest. State income tax may apply as well, depending on where you live.

Banks report interest to the IRS on a Form 1099-INT if you earn $10 or more in a calendar year. You'll receive a copy in January and must report it on your tax return. This is one reason high-yield savings accounts are useful for emergency funds — the interest is modest enough that the tax burden is small, but it's still better than earning nothing.

Savings accounts versus other places to keep money

Certificates of deposit (CDs) often pay higher rates than savings accounts but lock your money away for a set term — three months, one year, five years. If you withdraw early, you pay a penalty. Money market accounts are a middle ground: they pay rates close to high-yield savings accounts but may require a higher minimum balance. Regular checking accounts almost never pay meaningful interest.

For money you need to access quickly, a high-yield savings account is usually the best choice. For money you won't touch for a year or more, a CD may pay more. The difference between a 4.5% savings rate and a 5.2% one-year CD is small on most balances, so choose based on whether you might need the money.

How to find the highest rate for your situation

Websites like Bankrate, DepositAccounts, and NerdWallet list current savings rates at hundreds of banks and credit unions, updated daily. You can filter by account type, minimum balance, and whether you want an online or local bank. Read the fine print: some banks offer a promotional rate for the first few months, then drop to a much lower rate. Others require a minimum balance of $25,000 or more to earn the advertised rate.

If you're part of a credit union, check their rate first — credit unions often pay more than online banks and you may already have access. If you bank with a large national bank, compare their rate to what online banks are offering; the difference is usually worth switching if you have more than $5,000 to save.

Frequently Asked Questions

Do I earn interest if I withdraw money during the month?

Yes. Interest is calculated on your daily balance, so you earn interest on whatever amount you have in the account each day. If you start the month with $10,000, withdraw $3,000 on day 15, and end with $7,000, the bank calculates interest based on the daily balance for each of those days. You'll earn less than if you'd kept the full $10,000 there the whole time, but you still earn something.

What's the difference between APY and APR on a savings account?

APY (annual percentage yield) is what matters for savings accounts. It includes the effect of compounding — interest earned on interest. APR (annual percentage rate) is used for loans and doesn't include compounding. Banks advertise savings rates as APY, so the number you see is what you'll actually earn.

Can I lose money in a savings account?

No, as long as the bank is insured by the FDIC (Federal Deposit Insurance Corporation) or your credit union is insured by the NCUA (National Credit Union Administration). These agencies protect up to $250,000 per depositor per bank. Your balance won't shrink, though inflation can reduce what your money can buy over time.

Is a high-yield savings account safe?

Yes, if the bank is FDIC-insured. Online banks like Marcus, Ally, and Wealthfront are all FDIC-insured, so your deposits are protected the same way they would be at a physical bank. The only risk is that the rate drops, not that you lose the money itself.

How often should I check my savings account rate?

If you have less than $10,000 saved, checking once or twice a year is enough. If you have $25,000 or more, checking every three months makes sense — if your rate drops significantly and another bank is paying more, moving the money takes about a week and could earn you hundreds more per year.
