The bank offering the best rate today won't be the same bank next month
Interest rates move constantly. A savings account paying 4.5% this week might drop to 4.25% next week, and a competitor might jump from 3.8% to 5.1%. There is no single "best bank" — there is only the best rate available right now for the specific account type you need.
Online banks almost always beat brick-and-mortar banks because they have lower overhead costs. As of late 2024, online savings accounts routinely offer rates between 4% and 5.35%, while traditional banks like Chase, Bank of America, and Wells Fargo typically offer 0.01% to 0.5%. Credit unions sometimes match online rates, but not always. The gap between the highest and lowest rates can mean hundreds of dollars per year on a $10,000 deposit.
The catch: you cannot lock in a rate forever on a savings account. Banks can lower rates whenever they want. Certificates of Deposit (CDs) do lock in a rate for a fixed term — 3 months, 6 months, 1 year, 5 years — but you pay a penalty if you withdraw early. Knowing which account type fits your timeline matters more than chasing the single highest number today.
Key Takeaways
- Online banks offer savings rates 4 to 10 times higher than traditional banks because they have fewer physical branches and lower costs.
- The highest rates change weekly, so comparing rates on the day you open an account is more useful than remembering a rate from last month.
- CDs lock in a rate for a set period (3 months to 5 years), but you lose money if you withdraw early, so use them only for money you will not need.
- Money market accounts and high-yield savings accounts work the same way for rate purposes — the rate can drop at any time, but you keep full access to your money.
- Credit unions sometimes offer competitive rates, but you must be a member, and membership rules vary by location and employer.
Online banks versus traditional banks: why the gap exists
A Chase branch in your town costs money to staff, heat, and maintain. Chase passes that cost to customers by paying lower interest rates. An online bank like Marcus, Ally, or Wealthfront has no branches, no tellers, and no lease payments. They pass the savings to depositors in the form of higher rates.
This is not a temporary advantage. As long as online banks exist, they will pay more than traditional banks on savings accounts. The only exception is when the Federal Reserve raises or lowers its benchmark rate so sharply that all banks scramble to adjust — but even then, online banks move faster and higher.
Traditional banks do offer one real advantage: a physical location. If you need to deposit cash, withdraw large amounts in person, or talk to someone face-to-face, a branch matters. But if you are comfortable with mobile deposits and ATM networks, the rate difference is worth switching.
How to find the current highest rates
Do not rely on a website's list of "best banks" because those lists are often outdated within days. Instead, check rates directly on the bank's website or use a rate aggregator that updates multiple times per day. Bankrate, DepositAccounts, and DepositAccounts.com pull rates from hundreds of banks and update them frequently.
When you find a rate you like, open the account that same day if possible. Rates can drop overnight, and you want to lock in the rate you saw. Most online banks let you open an account in 10 to 15 minutes using your phone.
Pay attention to the account type, not just the number. A 5.2% rate on a CD that locks your money for 5 years is very different from a 5.2% rate on a savings account where the bank can drop it to 2% next month. Read the fine print to see whether the rate is fixed or variable.
Savings accounts: rates that can change anytime
A high-yield savings account (HYSA) is a regular savings account that pays a much higher rate than a traditional bank. The rate is variable, meaning the bank can lower it without warning. You keep full access to your money — no penalties, no waiting period.
Online banks offering competitive HYSA rates include Marcus (by Goldman Sachs), Ally Bank, American Express Personal Savings, and Wealthfront. Rates typically range from 4% to 5.35% depending on the week. Some credit unions also offer rates in this range, but you must be a member.
Use a HYSA for money you might need within the next year or two — an emergency fund, a down payment you are saving for, or money set aside for a known expense. Do not expect the rate to stay the same. If rates drop to 2%, you can move your money to a different bank, but you will have already earned less interest by then.
CDs: rates locked in for a set period
A Certificate of Deposit (CD) is a contract: you give the bank a sum of money, the bank pays you a fixed interest rate, and you agree not to touch the money until the term ends. Terms range from 3 months to 5 years. When the term ends, you get your principal plus interest, and the bank offers you a new rate for a new term.
CD rates are usually higher than savings account rates because the bank knows your money will stay put. As of late 2024, online banks offer CD rates between 4.5% and 5.5% depending on the term. Shorter terms (3 to 6 months) often pay less than longer terms (2 to 5 years), but this varies week to week.
The penalty for early withdrawal is real. If you open a 1-year CD at 5.2% and need the money after 6 months, the bank will charge you a penalty — often 3 to 6 months of interest. You will get your principal back, but you will lose some or all of the interest you earned. Only put money in a CD if you are certain you will not need it before the term ends.
Credit unions: membership required, rates sometimes competitive
Credit unions are member-owned financial institutions that sometimes offer rates as high as online banks. However, you must be a member to open an account, and membership rules vary. Some credit unions are open to anyone in a geographic area; others require you to work for a specific employer, belong to a specific organization, or have a family member who is already a member.
If you are already a credit union member, check their rates against online banks. Some credit unions offer excellent rates on savings accounts and CDs. Others do not. There is no way to know without asking or checking their website.
The advantage of a credit union is personal service and sometimes lower fees. The disadvantage is that you cannot join most credit unions without meeting their membership criteria, and their rates are not may provide to beat online banks.
Money market accounts: similar to savings, with check-writing
A money market account (MMA) is a hybrid between a savings account and a checking account. It pays interest like a savings account but lets you write checks or use a debit card like a checking account. The interest rate is variable, just like a savings account.
Online banks and some credit unions offer money market accounts with rates competitive to high-yield savings accounts — typically 4% to 5.2%. The main reason to choose an MMA over a savings account is if you want check-writing access. Otherwise, a savings account is simpler.
Money market accounts have the same risk as savings accounts: the rate can drop at any time. Use them for money you need access to, not for money you are trying to lock away.
What happens when rates drop
If you have money in a high-yield savings account or money market account and rates fall, your rate will fall too. The bank will notify you (usually by email) before the change takes effect. You can then move your money to a different bank offering a higher rate, or you can stay put.
If you have money in a CD, your rate is locked in until the term ends. When the term ends and the CD matures, the bank will offer you a new rate for a new term. That new rate might be higher or lower than what you earned before. You can accept the new rate, move the money to a different bank, or withdraw it.
This is why CDs are useful when rates are high: you lock in the good rate for a set period. If rates drop after you open the CD, you keep earning the higher rate while new CDs pay less.
Frequently Asked Questions
Can I move my money between banks if rates drop?
Yes. You can withdraw money from a savings account or money market account anytime without penalty and move it to a different bank. For CDs, you can only move the money without penalty after the term ends. If you withdraw early, you pay a penalty that typically equals 3 to 6 months of interest.
Is my money safe in an online bank?
Yes, as long as the bank is FDIC-insured. FDIC insurance protects up to $250,000 per account type per bank. Most online banks are FDIC-insured. Check the bank's website or call to confirm. Your money is just as safe in an online bank as in a traditional bank.
What if I need the money before my CD matures?
You can withdraw it, but you will pay an early withdrawal penalty. The penalty amount varies by bank and CD term — it might be 3 months of interest, 6 months of interest, or a flat fee. Before opening a CD, ask the bank what the penalty is. If there is any chance you will need the money, use a savings account instead.
Do I have to pay taxes on the interest I earn?
Yes. Interest earned on savings accounts, money market accounts, and CDs is taxable income. The bank will send you a 1099-INT form at the end of the year showing how much interest you earned. You report this on your tax return. This is true regardless of which bank you use.
Why do some banks offer promotional rates?
Banks sometimes offer higher rates for a limited time to attract new customers. These promotional rates usually last 3 to 12 months, then drop to the regular rate. Read the fine print to see when the promotional rate ends and what the regular rate will be.
