Yes, you earn money in a savings account through interest, but the amount depends on the rate your bank offers and how much you keep deposited

A savings account pays you interest on the money you hold in it. The bank takes deposits from many customers, lends that money out at higher rates, and shares a portion of what it earns back to you as interest. The amount you earn is calculated as a percentage of your balance — called the annual percentage yield, or APY. A $10,000 balance at 4.5% APY earns roughly $450 per year, paid in monthly or daily increments depending on how the bank compounds interest.

The catch is that interest rates vary widely. A large national bank might offer 0.01% APY on a basic savings account, meaning $10,000 earns $1 per year. An online bank or credit union might offer 4% to 5% APY on the same $10,000, earning $400 to $500 annually. The difference between these two scenarios is real money — and it compounds over time if you leave the balance untouched.

Key Takeaways

  • Interest rates on savings accounts range from near zero at large national banks to 4% to 5% at online banks and credit unions, so the bank you choose determines most of what you earn.
  • APY is the annual percentage yield — the percentage of your balance the bank pays you each year, usually divided into monthly or daily deposits.
  • Interest compounds, meaning you earn interest on your interest, so leaving money untouched for years increases your total earnings significantly.
  • Your balance must stay in the account to earn interest; withdrawals reduce the amount the bank calculates interest on for that period.

How banks calculate and pay interest

Banks calculate interest one of two ways: straightforward interest or compound interest. straightforward interest is rare in savings accounts. It means the bank pays you a percentage of your original balance only, so $10,000 at 5% straightforward interest earns $500 per year, every year, with no growth.

Most savings accounts use compound interest, which means you earn interest on your interest. If your account compounds daily, the bank divides your APY by 365, calculates interest on your current balance (including previously earned interest), and adds it to your account. After one month, you might have $10,041.67. The next month, interest is calculated on $10,041.67, not the original $10,000. Over years, this difference becomes substantial. A $10,000 balance at 4.5% APY compounded daily grows to roughly $14,918 after ten years without any additional deposits.

The bank deposits interest into your account on a schedule — usually monthly, sometimes daily. You can withdraw it when ready or leave it to compound further. Many people leave it untouched so it continues earning interest on a larger balance.

Why interest rates differ so much between banks

The rate your bank offers depends on its business model and the current economic environment. Large national banks with thousands of branches have high overhead costs — they pay for buildings, staff, and advertising. They pass some of that cost to customers by offering lower interest rates. Online banks have no physical branches, so their costs are lower, and they pass savings to customers through higher rates.

Credit unions, which are member-owned rather than shareholder-owned, often offer competitive rates because they return profits to members instead of shareholders. They may also offer higher rates to members who meet certain conditions — maintaining a minimum balance, setting up direct deposit, or using their debit card a certain number of times per month.

The Federal Reserve also influences rates. When the Fed raises its benchmark interest rate, banks typically raise the rates they offer on savings accounts. When the Fed cuts rates, bank rates fall. This means the rate you see today may not be the rate you see in six months. Some banks adjust rates weekly; others hold them steady for months.

The difference between APY and APR

You will see two terms: APY (annual percentage yield) and APR (annual percentage rate). For savings accounts, APY is what matters. APY includes the effect of compounding — it shows you the actual percentage you will earn over a year if you leave the money untouched. APR does not include compounding and is used mainly for loans and credit cards.

A bank might advertise "4.5% APY" on a savings account. That means if you deposit $10,000 and make no withdrawals or additional deposits, you will have $10,450 after one year (before taxes). If the same bank advertised "4.5% APR" on a savings account — which would be misleading — the actual earnings would be slightly less because it does not account for compounding.

What reduces or stops your earnings

Withdrawals reduce the amount of money earning interest. If you deposit $10,000 and withdraw $5,000 after six months, interest for the second half of the year is calculated on $5,000, not $10,000. Some accounts also charge monthly maintenance fees, which are deducted from your balance and reduce both your principal and future interest earnings.

Certain savings accounts limit how many withdrawals you can make per month without penalty. Federal rules previously capped withdrawals at six per month, though that rule was suspended in 2020 and has not been reinstated. Individual banks may still enforce limits. If you exceed the limit, the bank may charge a fee or close the account. Check your bank's withdrawal policy before opening an account if you plan to access the money frequently.

Inflation also reduces what your earnings are worth in real terms. If your savings account earns 1% APY but inflation is 3%, your money is losing purchasing power even though the balance is growing. This is why comparing your account's rate to current inflation matters — a 4.5% APY account in a 3% inflation environment is genuinely earning you 1.5% in real value.

How to find accounts with higher interest rates

Online banks and credit unions publish their current rates on their websites. You can compare rates across multiple institutions using financial websites that track savings account rates, though rates change frequently so the information may be a few days old. Call or visit the bank's website directly to confirm the current rate before opening an account.

Some accounts offer higher rates only if you meet conditions. A bank might offer 4.5% APY on balances up to $25,000 and 3.5% on anything above that. Another might require you to set up direct deposit or maintain a minimum balance. Read the terms carefully — the advertised rate may not explore to your situation.

Money market accounts and certificates of deposit (CDs) often pay higher rates than standard savings accounts. A money market account functions like a savings account but may require a higher minimum balance and limit withdrawals. A CD locks your money away for a set term — three months, one year, five years — and pays a fixed rate. You cannot withdraw the money early without paying a penalty, but the rate is may provide not to change during the term.

How taxes affect your savings account earnings

Interest earned in a savings account is taxable income. If your account earns $500 in interest during a calendar year, that $500 is reported to the IRS and you owe income tax on it at your regular tax rate. The bank sends you a 1099-INT form in January showing how much interest you earned the previous year.

The tax impact is small on low balances or low rates — $500 in interest might cost you $100 to $150 in taxes depending on your tax bracket — but it reduces your actual take-home earnings. This is why the difference between a 0.01% account and a 4.5% account matters even more after taxes. At a 24% tax rate, a $10,000 balance earning 4.5% nets you roughly $342 after taxes. The same balance at 0.01% nets you less than $1.

Frequently Asked Questions

Can I lose money in a savings account?

Your balance cannot go below zero due to interest calculations — interest only adds to your account. However, fees can reduce your balance if they exceed the interest you earn. Inflation can also reduce the purchasing power of your money even though the dollar amount grows. Your deposits are also protected by FDIC insurance up to $250,000 per account at most banks.

How often is interest added to my account?

Banks add interest on different schedules — some daily, some monthly. The frequency does not change your annual earnings much, but daily compounding is slightly better than monthly because interest accrues more often. Check your bank's disclosure documents or website to see how often interest is credited to your account.

What happens to my interest if I close the account?

You keep all interest earned up to the day you close the account. The bank calculates interest through your closing date and deposits it into the account before closing it, or you can withdraw it. No interest is lost by closing early.

Is a savings account the best place to earn money on my deposits?

Savings accounts are safe and liquid, but they earn less than stocks, bonds, or other investments over long periods. For money you need to access within a few years, a high-yield savings account or CD is reasonable. For money you will not need for ten years or more, other investments may earn more, though they carry more risk.
