Most high yield savings accounts have no minimum deposit requirement
You can open a high yield savings account with $0 to $1 in most cases. Banks like Marcus, Ally, American Express Personal Savings, and Discover have no stated minimum balance to open an account. Some regional banks and credit unions may require $25 to $500 to start, but the majority of online banks that offer competitive rates do not.
The catch is not the opening deposit — it is what happens after. Some accounts charge monthly fees if your balance falls below a certain threshold, usually $500 to $2,500. Others waive fees regardless of balance. A few accounts offer higher APY rates only if you maintain a minimum balance, though this is less common than it used to be.
Before you open an account, check the bank's fee schedule and rate terms. The difference between "no minimum to open" and "no monthly fees ever" matters if you plan to start small and build the account over time.
Key Takeaways
- Most online banks with high yield savings accounts charge no minimum deposit to open, but some regional banks require $25 to $500.
- Monthly maintenance fees may apply if your balance drops below a threshold, typically $500 to $2,500, so read the fee schedule before opening.
- A few banks offer higher APY only to accounts with balances above a certain amount, so compare rate tiers if you are starting with a small deposit.
- The APY rate itself does not depend on your opening deposit — you earn the same percentage whether you start with $1 or $10,000.
When banks charge fees based on your balance
Some high yield savings accounts waive their monthly maintenance fee only if you keep a minimum balance. For example, a bank might charge $5 per month unless your balance stays at $1,000 or above. If your balance dips below that threshold, the fee kicks in the following month.
This matters most if you are saving gradually. If you open an account with $100 and plan to add $50 per month, you could trigger fees for several months before reaching the minimum. Over a year, those fees can eat into the interest you earn. Check whether the bank waives fees for all customers or only for those who meet the balance requirement.
How your opening deposit affects your interest earnings
Your opening deposit does not change the interest rate you receive. If a bank advertises 4.50% APY, you earn that rate on every dollar in the account, whether you opened with $1 or $5,000. The APY is the same for all customers at that bank (though some banks offer different rates for different account types).
What matters is the total balance and how long it sits in the account. A $100 deposit earning 4.50% APY for one year generates about $4.50 in interest. A $1,000 deposit earns about $45. The rate is identical; the earnings scale with the balance.
Banks that require a deposit to open
Most online banks have no opening deposit requirement, but some do. Credit unions often require a small deposit to establish membership — typically $25 to $100. Some regional banks require $500 to $2,500 to open a savings account. A few specialty banks require $10,000 or more, though these are rare and usually not marketed as high yield savings accounts.
If you are comparing accounts and one requires a deposit you do not have, move on. Dozens of banks offer high yield rates with no opening deposit, so there is no reason to wait or scrape together money you need elsewhere.
What to do if you want to start with a very small amount
If you have only $10 or $50 to deposit, choose a bank with no opening minimum and no monthly fees. Marcus, Ally, and American Express Personal Savings all fit this profile. Open the account, make your initial deposit, and set up automatic transfers from your checking account if you want to add money regularly.
Some people worry that opening an account with a tiny balance looks odd or will trigger scrutiny. It does not. Banks process millions of small deposits every day. Your opening balance has no bearing on your account's standing or the rate you receive.

Frequently Asked Questions
Do I need to keep a minimum balance after I open the account?
Only if the bank charges a monthly fee for balances below a certain amount. Many banks do not — they let you keep any balance, even $0, without charging fees. Read the fee schedule. If a bank waives fees for all customers regardless of balance, you never have to worry about a minimum.
Will opening with a small deposit hurt my credit score?
No. Opening a savings account does not affect your credit score at all. Banks do not report savings account activity to credit bureaus. Your credit score only changes when you borrow money (loans, credit cards) and make or miss payments.
Can I earn the advertised APY on a small balance?
Yes. The APY applies to every dollar in the account. If you have $50 and the rate is 4.50%, you earn interest on that $50 at 4.50%. The rate does not change based on how much you have.
What if I want to move money out after I open the account?
You can withdraw your deposit anytime. There are no penalties for withdrawing from a savings account. Some banks limit the number of withdrawals per month (usually six), but opening and closing transfers do not count against that limit in most cases.
Should I wait until I have more money to open an account?
No. Open the account now if you have found a bank with no opening minimum and no monthly fees. You start earning interest immediately, even on a small balance. Waiting means you miss out on interest during the months you could have had money in the account.
