Yes, you should open both if you have money to set aside
A checking account is for money you spend regularly. A savings account is for money you want to keep separate and grow. If you have any amount you're not planning to touch for a few months—even $100—a savings account makes sense alongside your checking account. The two work together: checking handles your daily expenses, and savings keeps money from being accidentally spent.
Many banks let you open both at the same time, often with no extra fees. Some accounts even link them so you can transfer money between them when ready if you need to. The real question isn't whether to open both—it's whether you have money worth protecting from yourself.
Key Takeaways
- A checking account covers bills and everyday purchases; a savings account holds money you want to keep separate and not spend.
- Linking the two accounts lets you move money between them when ready without visiting a branch or waiting for a transfer.
- Savings accounts earn interest, meaning the bank pays you a small percentage of your balance each month—checking accounts typically do not.
- You can open both accounts in the same visit, often with the same bank, and many banks charge no monthly fee for either.
- If you have irregular income or unexpected expenses, a linked savings account acts as a buffer so you don't overdraft your checking.
How checking and savings accounts work together
Your checking account is designed for movement: money comes in, you write checks or use a debit card, money goes out. Banks expect this. Your savings account is designed for stillness: money sits there, earning a small return, and you touch it only when you plan to.
When you link them at the same bank, you can move money from savings to checking in seconds using your phone or online banking. This matters when an unexpected bill hits and your checking balance is low. Instead of overdrafting (which costs $30 to $35 per incident), you transfer $50 from savings and cover it. You stay in control and avoid fees.
The separation also works psychologically. Money in a savings account feels different from money in checking—it's slightly harder to spend, which is the point. If all your money sits in one checking account, the temptation to spend it is constant.
Interest rates and how much you'll earn
Savings accounts earn interest, which is money the bank pays you for letting them hold your money. Checking accounts almost never do. The difference matters more than it sounds, especially if you're saving several hundred dollars or more.
Interest rates vary by bank and change monthly. As of now, some online banks offer savings rates between 4% and 5% annually, while traditional brick-and-mortar banks often offer less than 1%. On $1,000, that's the difference between earning $40 to $50 per year versus $5 or less. Over time, that compounds—your interest earns interest.
You won't get rich on savings account interest. But if you're keeping money parked somewhere anyway, you might as well let it earn something. A checking account earns you nothing, so there's no trade-off.
When you might skip a separate savings account
If you have no money to set aside—if every dollar that comes in goes right back out for rent, food, or debt payments—a savings account won't help you yet. Opening one won't hurt, but it won't serve a purpose either. Focus first on getting your checking account stable and your income ahead of your expenses.
If you're using a bank that charges monthly fees for savings accounts, the math changes. Some banks charge $5 to $10 per month to maintain a savings account, which eats the interest you earn. In that case, look for a bank with no monthly fees on savings, or skip the savings account until you have enough to make the interest outpace the fee.
How to open both accounts at the same time
Most banks let you open a checking and savings account in a single process, either online or in a branch. You'll need the same documents for both: a government ID, proof of address (a recent utility bill or lease), and your Social Security number. Some banks also ask for an initial deposit, though many now let you open with $0 and deposit later.
Online banks typically have the fastest process—you can complete the process on your phone in 10 minutes and have both accounts active the same day. Traditional banks may take a few business days to process, and you might need to visit a branch to verify your identity in person, depending on their policy.
When you open both, ask the bank to link them. This is usually automatic, but confirming takes 30 seconds and ensures you can transfer money between them when ready. Some banks call this "linking" or "connecting"; the terminology varies, but the function is the same.
What to watch for when choosing a bank
Compare banks on three things: monthly fees, interest rates on savings, and whether they charge for transfers between your own accounts. A bank that charges $10 per month for a savings account is worse than a bank that charges nothing, even if the interest rate is slightly higher.
Check whether the bank has a physical branch near you or whether it's online-only. Online banks usually have lower fees and higher interest rates because they have no branches to maintain. But if you need to deposit cash or speak to someone in person, an online-only bank won't work for you.
Read the fine print on overdraft protection. Some banks automatically transfer money from savings to checking if you overdraft, which saves you a fee but costs you a small transfer fee instead. Others let you opt in or out. Understand the bank's policy before you open the account.
How much to keep in each account
There's no magic number, but a common starting point is to keep one month of essential expenses in checking and everything else in savings. If your rent, utilities, and groceries total $1,500 per month, keep $1,500 to $2,000 in checking and move the rest to savings.
This prevents you from accidentally spending money meant for next month's rent. It also means you're earning interest on the larger balance in savings instead of letting it sit idle in checking.
As your savings grows, some people move to a different split: keeping two weeks of expenses in checking and the rest in savings. The exact split depends on how often you get paid and how predictable your expenses are. If you get paid weekly and your expenses are steady, you can keep less in checking. If you get paid once a month or have irregular expenses, keep more.
Frequently Asked Questions
Can I have a checking account without a savings account?
Yes. Many people use only a checking account. But if you ever want to set money aside without spending it, a savings account makes that easier. You can always open one later—there's no penalty for starting with just checking.
Will opening a savings account hurt my credit score?
No. Banks check your credit when you open a checking or savings account, but opening either one does not lower your score. The inquiry is soft and does not affect your creditworthiness the way explore for a loan does.
What happens if I don't use my savings account?
Nothing negative. The money sits there earning interest. Some banks close accounts that have had no activity for a year or more, but they'll contact you first and let you reactivate it. As long as you keep a small balance, most banks won't close it.
Can I transfer money from savings to checking when ready?
Yes, if the accounts are at the same bank and linked. The transfer happens in seconds through your phone or online banking. If the accounts are at different banks, the transfer usually takes one to three business days.
Do I need a minimum balance to keep a savings account open?
It depends on the bank. Many online banks have no minimum. Traditional banks often require $100 to $500 to open and maintain the account. Check the bank's requirements before you open—some waive the minimum if you set up direct deposit.
