The rates you'll see depend on the bank type and how you search

Savings account interest rates vary widely—from nearly 0% at some brick-and-mortar banks to 4% or higher at online banks and credit unions. The difference matters: on $10,000, the gap between 0.01% and 4.5% is roughly $450 per year. The highest rates are almost always at online banks (which have lower overhead costs) and credit unions (which are member-owned and often prioritize competitive rates). Traditional banks with physical branches typically offer lower rates because they spend more on real estate and staff.

Rate shopping requires checking multiple places because banks change their rates weekly or even daily. A rate that was highest last month may not be this week. You won't find one master list that stays current—you have to visit bank websites directly, use rate-comparison sites like Bankrate or DepositAccounts, or call credit unions in your area. Even then, the rate you see online may apply only to new customers or to balances above a certain threshold.

Key Takeaways

  • Online banks currently offer the highest savings rates, typically 4% to 5.35%, because they don't maintain physical branches.
  • Credit unions often match or beat online bank rates and may offer better terms if you're a member, so check your employer or community credit union first.
  • Traditional banks with branches usually offer rates below 1%, even for new customers, because their operating costs are higher.
  • Rates change frequently, so comparing three to five banks before opening an account takes 15 minutes and can add hundreds of dollars annually.
  • Some banks offer higher rates only on balances above $25,000 or $100,000, so confirm the rate applies to your deposit size before opening.

Online banks: where the highest rates live

Online-only banks consistently offer the top savings rates because they have no branch network to maintain. As of recent months, rates at major online banks range from roughly 4% to 5.35% APY on standard savings accounts. Names you may recognize include Marcus, Ally, American Express Personal Savings, and Discover Bank. Smaller online banks like Wealthfront, Betterment, and Vanguard Digital Advisor sometimes offer rates in the same range or slightly lower.

The catch: online banks have no tellers, no phone support at most, and no way to deposit cash directly. You transfer money in and out via ACH (which takes one to three business days) or mobile deposit if they offer it. If you need to hand someone cash or speak to a person on the phone, an online bank won't work for you. Also, the highest advertised rate often applies only to new customers or to your first deposit—existing customers may see a lower rate after a promotional period ends.

Before opening, check whether the rate is permanent or promotional. Some banks advertise a 5% rate for three months, then drop to 3.5%. Read the terms carefully or call to ask how long the rate lasts and what happens after.

Credit unions: competitive rates and member perks

Credit unions are nonprofit organizations owned by their members, and many use higher savings rates as a way to attract and reward members. Rates at credit unions vary widely—some offer 4% or more, while others match traditional banks at under 1%. The rate depends on the specific credit union and sometimes on your membership tier or account type.

You may already be a member through your employer, your school, your union, or your geographic location. Check your employer's benefits page or search the CO-OP network (which connects credit unions nationwide) to see what's available to you. If you're not a member, you may be able to join by opening a savings account or paying a small membership fee—often $5 to $25.

Credit unions offer a real advantage if you need in-person service: most have physical branches and ATM networks. Some also offer phone support during business hours. The tradeoff is that their online platforms are sometimes less polished than online banks, and rates can be harder to find on their websites. Call or visit in person to ask about current savings rates.

Traditional banks: lower rates, familiar names

Banks like Chase, Bank of America, Wells Fargo, and Citibank offer savings accounts, but their rates are typically well below 1% APY—often 0.01% to 0.05%. These banks maintain thousands of branches and offer 24/7 phone support, which costs money. They pass those costs on by paying depositors less interest.

You might use a traditional bank for checking and bill pay but keep your savings at an online bank or credit union. Many people do this: they maintain a small savings account at their main bank for convenience, then move money to a higher-rate account elsewhere. There's no penalty for having accounts at multiple banks, and the interest difference can be substantial over time.

Money market accounts and CDs: different rates for different terms

If you're willing to lock money away or accept limits on withdrawals, you may find higher rates. Money market accounts (which function like savings accounts but often pay more) and certificates of deposit (CDs, which lock your money for a set term) sometimes offer rates 0.5% to 1% higher than standard savings accounts.

CDs are straightforward: you deposit money for three months, six months, one year, or longer, and you receive a fixed rate for that entire period. If you withdraw early, you pay a penalty (usually a few months of interest). Money market accounts let you withdraw anytime, like a savings account, but they may require a higher minimum balance and limit the number of withdrawals per month.

These options make sense if you have money you won't need for several months or longer. If you might need the cash sooner, a regular savings account is safer because you can withdraw without penalty.

How to compare rates and avoid common traps

Start by listing three to five banks or credit unions you want to check. Visit their websites and look for the savings account rate—it's usually labeled "APY" or "Annual Percentage Yield." Write down the rate, the minimum balance required, and whether it's a promotional rate or permanent. Then compare.

Watch for these traps: a rate that applies only to balances above $100,000 when you have $10,000; a promotional rate that expires after three months; a rate that's only for new customers and drops when you make your second deposit; or a rate that requires you to set up direct deposit or make a certain number of transfers per month to may have access to.

Use a rate-comparison site like Bankrate, DepositAccounts, or NerdWallet to see what's available, but verify the rate by visiting the bank's website directly. Comparison sites update regularly but may lag by a day or two. The bank's own website is always the source of truth.

FDIC insurance and safety

All banks and credit unions covered by FDIC or NCUA insurance protect your deposits up to $250,000 per account holder per institution. This means if the bank fails, you don't lose your money. Online banks are FDIC-insured just like traditional banks. Credit unions are insured by the NCUA, which works the same way.

Before opening an account, confirm the bank or credit union is FDIC or NCUA-insured. You can search the FDIC's BankFind tool or the NCUA's credit union locator on their websites. If a bank or credit union isn't insured, your money is at risk.

Frequently Asked Questions

Can I move money between banks without losing interest?

Yes. When you transfer money from one bank to another via ACH, the interest accrues based on where the money sits. If you move $5,000 from a 0.5% bank to a 4.5% bank mid-month, you'll earn the lower rate on that money for the days it was at the first bank, then the higher rate once it arrives at the second bank. There's no penalty for moving money.

Why do some banks offer much higher rates than others?

Online banks have lower operating costs (no branches, fewer staff), so they can afford to pay more interest and still be profitable. Traditional banks spend heavily on physical locations and customer service, so they pay less interest to offset those costs. Credit unions are nonprofit, so they return profits to members through higher rates.

Is a promotional rate worth switching banks for?

Only if the promotional period is long enough to make the switch worthwhile. A 5% rate for three months on $10,000 earns about $125 in extra interest compared to a 1% permanent rate. If switching takes an hour of your time, that's reasonable. If the rate drops to 1% after three months, you'd then need to move your money again or accept the lower rate.

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

Banks can lower rates anytime without penalty to you. Your money stays in the account earning the new (lower) rate. You're free to move it to another bank at any time. This is why rate shopping is ongoing—you may need to switch banks every year or two to keep earning competitive rates.

Do I need a minimum balance to earn the advertised rate?

Many banks do require a minimum—often $0, $500, $2,500, or $25,000. Check the bank's terms before opening. Some banks pay the full rate on all balances; others pay a lower rate if you fall below the minimum. Read the fine print or call to confirm.
