Most savings accounts do earn interest, but the rate depends on the bank and the account type

A savings account at a bank or credit union will pay you interest on the money you deposit — meaning the bank pays you a percentage of your balance each month or year. The amount you earn depends on the interest rate the bank offers, which changes based on what the Federal Reserve does with its benchmark rate and how much competition exists in your area.

Not every savings product earns the same rate. A traditional savings account at a big national bank might pay 0.01% annually, while a high-yield savings account at an online bank might pay 4% or 5%. The difference between these two is real money: on $10,000, you'd earn $1 per year at 0.01%, or $400 to $500 per year at 4.5%. Over time, that gap compounds.

The bank pays you interest because they lend out the money you deposit to other customers. They charge those borrowers a higher rate than they pay you, and keep the difference as profit. Your interest is the price they pay for the use of your money.

Key Takeaways

  • All FDIC-insured savings accounts earn interest, but rates vary widely — from under 0.1% at large national banks to 4% or higher at online banks.
  • Interest rates change based on Federal Reserve policy and bank competition, so the rate you see today may be different in six months.
  • High-yield savings accounts earn significantly more than traditional savings accounts at the same bank, even though both are equally safe.
  • Interest compounds, meaning you earn interest on your interest, so the longer money sits in an account, the more it grows.
  • Money market accounts and certificates of deposit (CDs) often pay higher rates than savings accounts, but with different rules about when you can withdraw.

How interest rates are set and why they change

Banks set their own interest rates, but they follow the lead of the Federal Reserve, which controls a benchmark rate that influences borrowing costs across the economy. When the Fed raises its rate, banks typically raise the rates they pay on savings accounts. When the Fed lowers its rate, banks usually lower savings rates too — sometimes within days, sometimes within weeks.

Banks also compete with each other. An online bank with low overhead costs can afford to pay higher rates than a brick-and-mortar bank with expensive branch locations. If you shop around, you'll find that rates differ significantly even when the Fed's rate is the same everywhere. Some banks raise rates quickly to attract new customers; others keep rates low because they have enough deposits already.

This means the interest rate you lock in today won't stay the same forever. Banks can change rates without notice, and they often do. If you want to know what your account will earn next month, you have to check back with your bank or compare rates across different institutions.

The difference between savings accounts, money market accounts, and CDs

A savings account lets you deposit and withdraw money whenever you want, with no penalty. Interest rates are typically lower because the bank can't count on keeping your money for any set period.

A money market account is a hybrid between a savings account and a checking account. It usually pays a higher interest rate than a savings account, but it may limit how many withdrawals you can make per month, and it often requires a higher minimum balance to open.

A certificate of deposit (CD) is an agreement where you give the bank a fixed amount of money for a fixed period — usually three months to five years. In exchange, the bank pays you a higher interest rate than a savings account. The catch: if you withdraw the money before the term ends, you pay a penalty that eats into your earnings. CDs are best for money you won't need to touch.

All three are insured by the FDIC up to $250,000 per account holder per bank, so your money is safe in any of them.

How compound interest works in a savings account

When a bank pays you interest, that interest gets added to your balance. The next time interest is calculated, you earn interest on the original amount plus the interest you already earned. This is called compounding, and it's how small interest rates turn into real money over time.

For example: if you deposit $5,000 in an account earning 4% annually, you'll earn $200 in the first year. If you don't withdraw that $200, your new balance is $5,200. In the second year, you earn 4% on $5,200, which is $208 — not $200. The extra $8 is interest on your interest. After 10 years at 4%, your $5,000 grows to about $7,400, even though you never added another dollar.

The longer your money sits in the account, the more compounding works in your favor. This is why starting early with even a small amount matters more than waiting to deposit a large amount later.

Why some banks pay much more interest than others

Online banks typically pay higher interest rates than traditional banks because they have lower operating costs. They don't maintain physical branches, don't employ as many staff, and don't spend money on advertising in the same way. Those savings get passed to customers in the form of higher rates.

Large national banks often pay lower rates because they have expensive branch networks and don't need to compete aggressively for deposits — many people keep money there out of habit or convenience. A regional bank might pay rates somewhere in the middle.

Credit unions, which are member-owned rather than shareholder-owned, sometimes pay competitive rates because they return profits to members rather than shareholders. However, not all credit unions pay high rates, and not all online banks do either. You have to compare specific accounts, not just categories.

The safest way to find the highest rate is to check rate-comparison websites that track current rates across multiple banks, or to visit bank websites directly. Rates change frequently, so a rate that was best last month might not be best this month.

What happens if you move your money or close the account

If you move money from one savings account to another, you don't lose the interest you've already earned — it stays in your account and moves with you. However, you do lose the future interest that account would have paid. If you close an account mid-month, you typically receive interest only through the day you close it.

Some banks calculate interest daily but pay it monthly, so the exact amount you receive depends on how many days your money was in the account. If you're moving money to a higher-rate account, the sooner you move it, the sooner you start earning the better rate.

Switching accounts is free and doesn't hurt your credit. Many online banks make it easy by offering to transfer money from your old account automatically, so you don't have to do it manually.

Frequently Asked Questions

How often does a bank pay interest on a savings account?

Most banks calculate interest daily but deposit it monthly. Some deposit quarterly or annually. Check your account agreement or ask your bank how often interest posts. The more frequently interest compounds, the more you earn, though the difference is usually small if the rate is the same.

Can I lose money in a savings account?

No, as long as your balance stays under $250,000 and the bank is FDIC-insured. Your money is protected even if the bank fails. However, if inflation rises faster than your interest rate, the purchasing power of your money decreases — you can buy less with it — even though the dollar amount stays the same.

Is a high-yield savings account safe?

Yes, if the bank is FDIC-insured. High-yield accounts are just regular savings accounts with higher interest rates. The safety is the same; only the rate is different. Check the bank's website or the FDIC's bank search tool to confirm it's insured.

What's the highest interest rate I can find right now?

Rates change constantly and vary by bank. As of early 2024, some online banks offered rates between 4% and 5%, but this will change as the Federal Reserve adjusts its policy. Check rate-comparison websites or bank websites directly to see current rates in your area.

Do I have to pay taxes on savings account interest?

Yes, interest earned on a savings account is taxable income. Banks report interest over $10 on a 1099-INT form. The amount you owe in taxes depends on your tax bracket. Keep records of interest earned so you can report it accurately when you file your taxes.
