The best rate depends on what you're willing to trade for it

There is no single "best" savings account interest rate because the highest rate available to you depends on the type of account you open and the bank or credit union you choose. Online banks typically offer higher rates than brick-and-mortar banks because they have lower overhead costs. Credit unions sometimes offer competitive rates to their members. The trade-off is usually convenience: online banks have no physical branches, and credit unions require membership.

As of early 2024, online savings accounts pay between 4.5% and 5.35% APY, while traditional banks often pay 0.01% to 0.5% APY on the same type of account. That difference matters: on $10,000, the gap between 0.5% and 5% is $450 per year. The highest rates change weekly as banks adjust their offerings, so the specific number that was highest last month may not be highest this week.

Key Takeaways

  • Online banks pay significantly higher interest rates than traditional banks because they operate without physical branches and pass the savings to depositors.
  • The highest rates are not always at the same institution month to month, so comparing current offers before opening an account matters.
  • Money market accounts and high-yield savings accounts offer similar rates, but money market accounts may include a debit card and check-writing ability.
  • Credit unions sometimes match or exceed online bank rates for members, but membership requirements vary by location and employer.
  • FDIC insurance covers up to $250,000 per account type per bank, so splitting money across institutions protects larger balances.

How online banks offer higher rates than traditional banks

Online banks have no tellers, no building leases, and no regional branch networks. Those costs add up: a traditional bank's overhead can run 2% to 3% of its total expenses. Online banks cut that to less than 1%. They pass some of that savings to customers through higher interest rates on deposits.

The money you deposit still gets lent out—that's how banks make profit—but online banks can afford to pay you more of what they earn because they spend less to keep the lights on. A bank paying 5% APY is not being generous; it is competing for deposits by offering a rate that still leaves room for profit after paying its staff and systems.

Where the highest rates actually live

The institutions offering the highest rates change frequently, but the categories stay consistent. Online savings banks (Marcus by Goldman Sachs, Ally, American Express Personal Savings, Wealthfront Cash Account) and online credit unions (Pentagon Federal Credit Union, Connexus Credit Union) are where you find the top rates. Some traditional banks offer competitive rates on specific products—Discover Bank, for instance, is an online division of a traditional bank and pays rates comparable to pure online competitors.

Rate comparison sites like Bankrate, DepositAccounts, and DepositAccounts track current rates across hundreds of institutions and update daily. These sites let you filter by account type, minimum balance, and whether you need a physical location nearby. The rates shown are current as of the date listed, but you should verify the rate on the bank's own website before opening an account, because banks can change rates without notice.

High-yield savings accounts versus money market accounts

Both account types pay similar interest rates at the same institution, but they differ in how you access your money. A high-yield savings account is a savings account: you can withdraw funds, but there is no debit card and no check-writing. A money market account functions like a hybrid—it pays savings-account interest rates but may include a debit card, checks, or limited check-writing (often capped at three checks per month).

If you need to write checks or use a debit card regularly, a money market account offers that flexibility at the same rate as a high-yield savings account. If you want to keep the money separate and untouched, a high-yield savings account removes the temptation to spend it. The interest rate is what matters most; the account structure is secondary.

Credit unions and membership-based rates

Credit unions are member-owned cooperatives, not shareholder-owned banks. Some credit unions offer rates that match or exceed online banks, particularly on savings accounts. Pentagon Federal Credit Union and Connexus Credit Union, for example, both offer rates in the 4.5% to 5% range and accept members nationwide.

The catch is membership. Pentagon Federal requires military service or employment in certain federal agencies, or membership in a sponsoring organization. Connexus is open to anyone in participating states. Other credit unions are restricted to employees of a specific company, residents of a specific county, or members of a specific profession. Before comparing rates, check whether you meet the membership requirements. If you do, credit unions are worth comparing because their rates are often competitive and their customer service tends to be more personal than online banks.

What happens to your rate when the Federal Reserve changes course

Bank interest rates follow the Federal Reserve's benchmark rate, which is the interest rate at which banks lend to each other overnight. When the Fed raises its rate, banks raise the rates they pay on deposits. When the Fed cuts its rate, banks cut deposit rates. The lag is usually one to four weeks.

This matters because the highest rate you see today may not be the highest rate next month. If the Fed is cutting rates (as it did in late 2023 and early 2024), rates on savings accounts will fall across the board. If the Fed is holding steady or raising, rates tend to stay put. You cannot predict what the Fed will do, but you can lock in a rate by opening an account when rates are high. The rate you open with is the rate you keep, even if the bank lowers its rate for new customers later.

How FDIC insurance affects where you should split your money

The Federal Deposit Insurance Corporation (FDIC) insures deposits up to $250,000 per account type per bank. That means if you have $250,000 in a savings account at Bank A and $250,000 in a savings account at Bank B, both are fully insured. If you have $500,000 in a savings account at Bank A, only $250,000 is insured.

This is relevant to rate-chasing because it means you may need to split large balances across multiple banks to stay fully insured. If you have $500,000 to deposit and want the highest rate, you might put $250,000 at the bank with the absolute highest rate and $250,000 at the bank with the second-highest rate. You lose a small amount of interest on the second portion, but you keep both portions insured. Credit unions have a similar insurance structure through the National Credit Union Administration (NCUA).

Frequently Asked Questions

Do I have to keep a minimum balance to get the advertised rate?

Most online banks do not require a minimum balance to open an account or earn the advertised rate. Some traditional banks require $500 to $2,500 to avoid a monthly fee or to earn the full rate. Check the bank's account terms before opening. If a minimum balance is required and you cannot meet it, the account may cost you money in fees rather than earn you interest.

Can I move my money out whenever I want?

Yes. Savings accounts and money market accounts have no lock-in period. You can withdraw your money the same day you deposit it. The only limit is that federal rules once capped withdrawals at six per month, but that rule was suspended in 2020 and has not been reinstated. Your bank may have its own limits, so check the account agreement, but most online banks allow unlimited withdrawals.

What if the bank lowers its rate after I open an account?

Banks can lower rates for new customers at any time, but they cannot lower the rate on your existing balance without notice. You will receive notification (usually 30 days in advance) if your rate is being lowered. At that point, you can move your money to a different bank if you want. Many people do this when rates drop significantly, which is why banks sometimes raise rates to attract new deposits—they are competing for your money.

Is an online bank safe if it has no physical location?

Online banks are regulated by the same federal agencies as traditional banks and are FDIC-insured the same way. The lack of a physical branch does not make them less safe; it makes them cheaper to operate. Your money is just as protected at an online bank as it is at a bank with a building on Main Street.

Should I move my money every time a new bank offers a higher rate?

Moving money frequently costs time and carries a small risk of error during the transfer. If a rate difference is 0.1% or 0.2%, the extra interest you earn may not be worth the effort. If the difference is 0.5% or more and you have a large balance, moving makes sense. Use a rate comparison site to check the landscape once every three to six months rather than chasing every small change.
