The main choice is between a bank branch, a credit union, or an online bank

You can open a savings account at a traditional bank with physical branches, a credit union, or an online-only bank. Each route has different trade-offs: branch banks offer in-person service and ATM networks; credit unions often charge lower fees and pay higher interest rates but have smaller networks; online banks typically pay the highest interest rates but have no branches or phone support. Your choice depends on whether you value convenience, low fees, high returns, or some combination of the three.

The account itself works the same way regardless of where you open it. You deposit money, earn interest on your balance, and can withdraw funds. The differences lie in how much interest you earn, what fees you pay, how you access your money, and what customer service looks like.

Key Takeaways

  • Online banks typically offer the highest interest rates because they have no branch costs, but they have no physical locations and limited phone support.
  • Traditional banks offer ATM access and in-person service but often charge monthly fees and pay lower interest rates than online competitors.
  • Credit unions usually charge fewer fees and pay competitive interest rates, but membership is limited to specific groups and their ATM networks are smaller.
  • You will need a government ID, proof of address, and an initial deposit amount (which varies by institution, often $0 to $25).
  • Opening an account takes 10 to 30 minutes online or in person, and your account is usually active the same day or within one business day.

Online banks: highest interest rates, no branches

Online banks pay the highest savings account interest rates because they operate no physical branches and have lower overhead costs. Banks like Marcus, Ally, and American Express Personal Savings are examples. You open an account entirely online, deposit money by electronic transfer from another bank account, and manage everything through a website or mobile app. There are no ATMs, no tellers, and no local branch to visit.

The trade-off is customer service. Most online banks offer email support and limited phone lines, but no in-person help. If you need to deposit cash, you cannot do it at an online bank—you must transfer money electronically from another account. Interest rates at online banks change frequently and vary by institution; you should compare current rates before opening an account because the highest-paying bank today may not be the highest-paying bank in three months.

Online banks are best if you rarely need cash, prefer managing money on your phone, and want to maximize interest earnings. They are less suitable if you deposit cash regularly or need same-day help with account problems.

Traditional banks: ATM access and in-person service

Traditional banks like Bank of America, Wells Fargo, and Chase have physical branches where you can walk in, speak to a teller, and deposit cash. They offer ATM networks (sometimes nationwide, sometimes regional), paper statements, and phone support during business hours. You can open an account in person or online, and many let you start with $0 down, though some require $25 to $100.

The cost of this convenience is lower interest rates and higher fees. Many traditional banks charge monthly maintenance fees ($5 to $15) unless you meet conditions like maintaining a minimum balance or setting up direct deposit. Interest rates are typically much lower than online banks—sometimes 0.01% or less. If you keep a small balance and do not earn much interest anyway, the fee may matter more than the rate. If you keep a large balance, the lower rate costs you real money over time.

Traditional banks work well if you deposit cash frequently, need same-day help, or prefer face-to-face banking. They are less efficient if you want to maximize interest or minimize fees.

Credit unions: lower fees and competitive rates for members

Credit unions are member-owned financial institutions that often charge lower fees and pay higher interest rates than traditional banks. Examples include Navy Federal Credit Union, Connexus Credit Union, and Alliant Credit Union. The catch is membership: you can only join a credit union if you meet their membership criteria, which might be working for a specific employer, living in a certain area, belonging to a particular organization, or having a family member who is already a member.

Once you are a member, you can open a savings account with no monthly fee at many credit unions, and interest rates are often competitive with online banks. Credit unions typically offer ATM access through shared branching networks, though the network is smaller than a major bank's. You can open an account in person at a branch or online if the credit union offers it.

Credit unions are worth exploring if you meet their membership requirements and want a middle ground between online banks and traditional banks—lower fees than big banks, higher rates than most branches, and some in-person service. If you do not meet membership criteria, you cannot open an account there.

What you need to open an account

Regardless of where you open a savings account, you will need a government-issued photo ID (driver's license, passport, or state ID), proof of your current address (utility bill, lease, or bank statement dated within the last 60 days), and your Social Security number. Some institutions also ask for your employment information or a phone number.

Most banks and credit unions require an initial deposit to open the account. This amount varies: some online banks and credit unions require $0, while traditional banks often require $25 to $100. A few institutions waive the minimum if you set up automatic transfers or direct deposit. Check the specific institution's requirements before you start the process.

If you do not have a government ID, some banks will accept alternative documents like a passport card, tribal ID, or consular ID. Call ahead to ask what they accept. If you do not have a Social Security number, some banks and credit unions offer accounts for non-citizens using an ITIN (Individual Taxpayer Identification Number) instead.

How to compare accounts before you open one

Before opening an account, compare three things: the interest rate (called APY, or Annual Percentage Yield), monthly fees, and how you will access your money. The APY tells you how much interest you will earn in a year; a higher rate means more money in your account over time. Monthly fees reduce your balance every month, so a $10 fee on a $500 account costs you 2% of your balance annually.

Use a calculator to see the real difference. If you plan to keep $5,000 in the account for a year, an online bank paying 4.5% APY with no fees will earn you $225. A traditional bank paying 0.01% APY with a $10 monthly fee will cost you $120 in fees and earn you $0.50, for a net loss of $119.50. The difference compounds over years.

Write down the APY, monthly fees, minimum balance requirements, and ATM access for three to five institutions you are considering. Then decide which matters most to you: the highest rate, the lowest fees, the best access, or a balance of all three.

Opening an account online versus in person

Opening an account online takes 10 to 20 minutes. You enter your personal information, upload a photo of your ID and proof of address, agree to the terms, and choose a username and password. The bank verifies your identity (usually instantly or within one business day) and your account is ready to use. You can then transfer money from another bank account to fund it.

Opening an account in person takes 15 to 30 minutes. You bring your ID and proof of address, speak with a banker or teller, sign documents, and make your initial deposit in cash or check. Your account is usually active the same day. In-person opening is useful if you want to deposit cash immediately or prefer to ask questions face-to-face.

Both routes are equally safe. Online banks use encryption and identity verification to prevent fraud. Traditional banks verify your identity in person. Either way, your deposits are insured by the FDIC (Federal Deposit Insurance Corporation) up to $250,000 per account, per bank, so your money is protected if the bank fails.

Frequently Asked Questions

Can I open a savings account if I do not have a Social Security number?

Yes. Some banks and credit unions accept an ITIN (Individual Taxpayer Identification Number) instead. Call the institution first to confirm they accept ITINs, because not all do. You will still need a government ID and proof of address.

What is the difference between a savings account and a checking account?

A savings account is designed for storing money and earning interest; you can usually make only a limited number of withdrawals per month. A checking account is designed for frequent transactions; you get a debit card and checks and can withdraw as much as you want. Most people have both.

Do I have to keep a minimum balance in my savings account?

It depends on the bank. Some accounts require you to maintain a minimum balance (often $500 to $2,500) to avoid a monthly fee or to earn interest. Others have no minimum. Read the account terms before you open it, because falling below the minimum can trigger fees.

How long does it take to transfer money into my new savings account?

Electronic transfers between banks usually take one to three business days. If you open an account in person and deposit cash or a check, the funds are available immediately (for cash) or within one to two business days (for checks). Online banks cannot accept cash deposits, so you must transfer money electronically.

Is my money safe in an online bank?

Yes. Online banks are regulated by the same federal agencies as traditional banks and your deposits are insured by the FDIC up to $250,000. Online banks use encryption and security measures to protect your account. The main risk is user error—using a weak password or falling for a phishing email—not the bank itself.
