What you earn depends on the bank, the account type, and the current rate environment

The amount of interest a savings account earns varies widely. A high-yield savings account at an online bank might pay 4.00% to 5.35% annual percentage yield (APY) right now, while a traditional savings account at a brick-and-mortar bank might pay 0.01% to 0.05%. The difference between these two is enormous: on $10,000, you'd earn roughly $400 to $535 per year at a high-yield rate, or $1 to $5 per year at a traditional rate.

The rate you see advertised is the APY — the amount you earn in a year if you leave the money untouched and the rate stays the same. Banks set their own rates based on what the Federal Reserve does with its benchmark rate, how much competition exists in their market, and how badly they need deposits. When the Fed raises its benchmark rate, banks usually raise savings rates within weeks. When the Fed cuts rates, banks often cut savings rates faster than they raised them.

Your actual earnings also depend on how often interest compounds — daily, monthly, or quarterly. Daily compounding means you earn interest on your interest more frequently, which adds up slightly faster. Most online banks compound daily, which is why they tend to offer higher effective returns than banks that compound monthly.

Key Takeaways

  • High-yield savings accounts currently pay 4.00% to 5.35% APY, while traditional bank savings accounts typically pay 0.01% to 0.05% APY.
  • The rate you earn is set by the individual bank, not by the government, and changes when the Federal Reserve adjusts its benchmark rate.
  • Daily compounding produces slightly higher returns than monthly or quarterly compounding because you earn interest on your interest more often.
  • Your earnings are insured up to $250,000 per account by the FDIC at banks or the NCUA at credit unions, regardless of the rate.
  • Rates change frequently, so comparing banks before you open an account matters more than locking in a rate today.

How banks decide what rate to offer you

Banks don't set savings rates based on what they think is fair. They set them based on what they need to do to attract deposits and what they can afford to pay while still making a profit on loans.

When the Federal Reserve raises its benchmark interest rate, banks have to pay more to borrow money from each other. They pass some of that cost to depositors by raising savings rates. When the Fed cuts rates, banks can borrow more cheaply, so they cut what they pay you — often faster and deeper than rates rose. This is why your savings rate can drop 0.50% or more in a few months when the Fed starts cutting, even though it took months for rates to climb that high.

Online banks tend to offer higher rates than traditional banks because they have lower overhead costs (no branches, fewer employees) and they compete aggressively for deposits. A traditional bank might offer 0.03% APY while an online bank offers 4.50% APY on the same type of account. The online bank can afford to pay more because it spends less on operations.

The difference between APY and interest rate

APY and interest rate sound like the same thing, but they're not. The interest rate is the percentage the bank pays on your balance. The APY is what you actually earn in a year when compounding is included.

If a bank offers a 4.80% interest rate compounded daily, the APY might be 4.92% because you're earning interest on your interest every single day. The difference is small but real — over a year on $50,000, that 0.12% difference adds up to about $60. Banks are required to show you the APY, not just the interest rate, so you can compare accounts fairly.

When you see a rate advertised, it's almost always the APY. That's the number to use when you compare one bank to another.

How to calculate what you'll actually earn

The math is straightforward. Multiply your balance by the APY, then divide by 12 to get your monthly earnings (assuming the rate doesn't change).

Example: You have $25,000 in a savings account earning 4.50% APY. Multiply $25,000 × 0.045 = $1,125 per year. Divide by 12 = $93.75 per month. If you leave the money untouched and the rate stays the same, you'll earn about $94 per month.

In reality, rates change. If your bank cuts the rate to 4.00% midway through the year, you'll earn less. If they raise it to 5.00%, you'll earn more. Most banks show you the interest you've earned so far in your account statement or online dashboard, so you can see the actual number rather than calculating it yourself.

Why rates change and what to watch for

Savings rates move when the Federal Reserve changes its benchmark rate, which it does roughly every six to eight weeks during active rate-setting periods. The Fed doesn't set your savings rate directly — it sets the rate that banks charge each other to borrow overnight. Banks use that as a reference point for what they'll pay you.

The Fed raises rates when inflation is too high and cuts rates when the economy is slowing. These decisions happen months or years apart, so your savings rate can stay flat for long stretches. From 2020 to 2021, rates were near zero. From 2022 to 2023, they climbed rapidly. Rates have stabilized in 2024, but they could move again depending on economic conditions.

You don't need to predict what the Fed will do. You just need to know that if you're earning 4.50% today and rates start falling, your bank will cut your rate within a few weeks. If you want to lock in a higher rate, you can move your money to a bank offering a better rate at any time — there's no penalty for moving savings between banks.

High-yield savings accounts versus money market accounts

High-yield savings accounts and money market accounts often pay similar rates, but they work differently. A high-yield savings account is a basic savings account with no check-writing or debit card. A money market account usually comes with a debit card and check-writing privileges, but limits how many withdrawals you can make per month (often six).

Both are FDIC-insured up to $250,000 and both pay interest daily or monthly. The rate difference between them is usually small — sometimes the money market account pays slightly more, sometimes slightly less. The choice comes down to whether you need the ability to write checks or use a debit card. If you're parking money you won't touch for months, a high-yield savings account is simpler. If you want the flexibility to withdraw by check, a money market account gives you that option.

Certificates of deposit (CDs) are a different product entirely. They lock your money away for a set term (three months to five years) in exchange for a may provide rate, usually higher than savings accounts. You can't withdraw early without a penalty, so they're only worth it if you know you won't need the money during the term.

FDIC insurance and what it means for your earnings

Your savings account interest is insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account, per bank. This means if the bank fails, the FDIC will pay you back your balance plus all interest earned, up to $250,000 total.

The insurance covers the principal and the interest together, not separately. If you have $240,000 in a savings account and earn $10,000 in interest, the FDIC covers all $250,000. If you have $245,000 and earn $10,000, the FDIC covers only $250,000 — you lose $5,000.

This is why people with large balances sometimes split their money across multiple banks. Each bank account is insured separately, so $250,000 at Bank A and $250,000 at Bank B are both fully covered. Credit unions use the same system through the NCUA (National Credit Union Administration) instead of the FDIC, but the coverage limit is identical.

Frequently Asked Questions

Is the interest I earn on a savings account taxable?

Yes. The IRS treats savings account interest as ordinary income. If you earn $500 in interest, you owe income tax on that $500 at your regular tax rate. Banks send you a 1099-INT form in January if you earned $10 or more in interest during the year. You report this on your tax return.

Can a bank lower my interest rate without warning?

Yes. Banks can change savings rates at any time without notice. They usually announce the change on their website or in your account dashboard, but they're not required to give you advance warning. If your rate drops and you don't like it, you can move your money to another bank that offers a higher rate.

Why do some banks offer much higher rates than others?

Online banks have lower costs than traditional banks, so they can afford to pay more. They also compete aggressively for deposits because they can't rely on foot traffic or existing customer relationships. A traditional bank might pay 0.05% because most of its customers won't move their money, while an online bank pays 4.50% to attract new customers from competitors.

What happens to my interest if I withdraw money mid-month?

Most banks calculate interest daily based on your balance each day. If you withdraw money on the 15th of the month, you earn interest on the full balance for the first 14 days, then on the lower balance for the remaining days. You don't lose interest you've already earned, but you earn less going forward because your balance is smaller.

Is there a minimum balance to earn interest?

It depends on the bank. Some banks pay interest on any balance, even $1. Others require a minimum balance like $500 or $1,000 to earn the advertised rate. If your balance falls below the minimum, you might earn a lower rate or no interest at all. Check the bank's terms before you open an account.
