A savings account is worth opening if you have money sitting in checking that you're not spending month to month, or if you're building toward a specific goal

The main reason to open one is simple: a savings account pays you interest on the money you keep there, while a checking account usually does not. That interest is small—often less than 1% per year at most banks—but it adds up over time, especially if you have several thousand dollars sitting still. A savings account also creates a mental boundary between money you spend now and money you're keeping for later, which makes it harder to accidentally drain funds you meant to save.

You don't need a savings account if you have very little money, if you spend everything you earn, or if you already use a separate tool like a money market account or certificate of deposit. But if you have a few hundred dollars or more that you're not touching each month, opening one takes 15 minutes online and costs nothing.

Key Takeaways

  • A savings account pays interest on your balance, while checking accounts typically pay nothing, so the difference grows as your balance grows.
  • Interest rates vary widely between banks—from under 0.01% at large national banks to over 4% at online banks—so comparing before you open matters.
  • You can open a savings account at the same bank where you have checking, or at a different bank that offers better interest rates.
  • Savings accounts have withdrawal limits in some cases, though federal rules no longer cap how many times you can withdraw per month.
  • Moving money between checking and savings takes one to three business days if the banks are different, so plan ahead if you need the cash quickly.

How much interest you'll actually earn depends on the bank and the rate environment

The interest rate a bank offers on savings accounts changes based on what the Federal Reserve does with interest rates overall. When the Fed raises rates, banks raise savings rates. When the Fed lowers rates, banks lower savings rates. Right now, online banks typically offer rates between 4% and 5.35% per year, while large national banks like Chase and Bank of America often offer rates below 0.01%.

The difference is real money. On a $5,000 balance, you'd earn roughly $200 to $270 per year at an online bank, versus less than $1 per year at a national bank. Over five years, that's $1,000 versus $5. You don't need to chase the absolute highest rate, but comparing three or four banks before you open an account takes 10 minutes and can double or triple what you earn.

Some banks offer higher rates only on balances above a certain amount—say, $25,000—so read the fine print. Others offer a promotional rate for the first few months, then drop to a much lower rate. Check what the regular rate is, not just the promotional one.

Opening an account online is faster than going to a branch

Most banks let you open a savings account entirely online. You'll need a government ID, your Social Security number, and a way to fund the account—usually a debit card or a transfer from another bank account. The whole process takes 10 to 20 minutes, and your account is usually active the same day or the next business day.

If you already have checking at a bank, opening a savings account there is the fastest route—sometimes you can do it in the mobile app in under five minutes. But if you want a higher interest rate, you may need to open at a different bank. That's fine; you can have accounts at multiple banks with no penalty.

When you open at a new bank, you'll need to fund the account with an initial deposit. Most banks require between $0 and $25 to start, though some have no minimum. You can transfer money from your existing checking account, or deposit a check through the mobile app if the bank offers mobile deposit.

Moving money between checking and savings takes time if the banks are different

If your checking and savings are at the same bank, transfers between them are usually instant or take a few minutes. If they're at different banks, the transfer takes one to three business days because the banks have to process it through the Federal Reserve's system.

This matters if you're thinking of using savings as an emergency fund. If you need the money in a few hours, you won't be able to get it from a savings account at a different bank. Keep your emergency fund in checking, or at least in a savings account at the same bank as your checking so you can move it instantly.

Some online banks offer a linked checking account, which lets you transfer money between them instantly even though they're technically separate accounts. If you're opening a savings account at an online bank, ask whether they offer this.

Savings accounts have fewer restrictions than they used to, but some limits still exist

Federal rules used to cap how many times per month you could withdraw from a savings account—usually six times. Those rules were suspended in 2020 and have not come back, so most banks now allow unlimited withdrawals. However, some banks still impose their own limits, so check before you open.

What matters more is that most banks charge a fee if your balance drops below a certain amount—often $300 to $500. If you're opening a savings account with $100 and plan to leave it alone, you might get hit with a monthly fee that eats into your interest. Look for banks with no minimum balance requirement, or make sure you can keep the minimum they do require.

Some savings accounts are labeled "high-yield" or "money market" accounts. These are still savings accounts—they work the same way—but they usually offer higher interest rates in exchange for a higher minimum balance. If you have $10,000 or more to save, a high-yield account might pay more than a regular savings account at the same bank.

You might not need a savings account if you have other options

A certificate of deposit (CD) pays higher interest than a savings account, but you have to lock your money away for a set time—usually three months to five years. If you won't need the money for at least a year, a CD might pay more. If you might need it sooner, a savings account is more flexible.

A money market account is a hybrid: it works like a savings account but usually pays higher interest, though it often requires a higher minimum balance. Some people use money market accounts instead of savings accounts if they have enough money to meet the minimum.

If you're saving for a specific goal—a house down payment, a car, a vacation—some banks offer goal-based savings tools that let you create separate "buckets" within one account. These are just regular savings accounts with a different interface; they don't pay more interest, but they can help you organize your money psychologically.

Comparing banks before you open takes 15 minutes and can save you hundreds

Start by listing what matters to you: interest rate, minimum balance, fees, whether you want it at your current bank or elsewhere, and whether you need instant transfers. Then visit the websites of three to five banks and note their rates and requirements. Bankrate, NerdWallet, and DepositAccounts all list current rates across many banks, though you should verify the rate on the bank's own website before you open.

Pay attention to whether the rate is promotional or permanent. A bank advertising 5% might only offer that rate for the first three months, then drop to 0.5%. Read the terms, not just the headline number.

Once you've picked a bank, opening takes 15 minutes. You can close the account later with no penalty if you change your mind, so there's no risk in trying one out.

Frequently Asked Questions

Can I have a savings account at one bank and checking at another?

Yes. You can have accounts at as many banks as you want. Transfers between different banks take one to three business days, so if you need money quickly, keep your emergency fund in checking or at the same bank as your savings.

Will opening a savings account hurt my credit score?

No. Opening a savings account does not trigger a hard credit inquiry and does not affect your credit score. Banks may do a soft check to verify your identity, but that doesn't show up on your credit report.

What happens to my interest if I withdraw money?

Interest is calculated on your daily balance and paid out monthly or daily, depending on the bank. If you withdraw money mid-month, you earn interest only on the amount you had for the days you held it. You don't lose interest you've already earned.

Is my money safe in a savings account?

Yes, if the bank is FDIC-insured. The FDIC guarantees up to $250,000 per account holder per bank, so your money is protected even if the bank fails. All major banks are FDIC-insured; check the bank's website to confirm.

Should I open a savings account if I only have $100?

It depends on the bank's minimum balance requirement. If the bank charges a monthly fee for balances under $300, a $100 account will lose money to fees. Look for banks with no minimum balance requirement, or wait until you have more to save.
