Most high yield savings accounts have no minimum deposit requirement
You can open a high yield savings account with $0 to $1 in many cases. Banks like Marcus, Ally, and American Express Personal Savings have no stated minimum balance to open an account or keep it open. Some online banks will let you fund the account after you've created it, meaning you can complete the signup process and deposit money later.
The catch is not the opening deposit—it's what happens after. Once your account is open, the interest rate you see advertised applies only to the balance you actually hold. If you deposit $100, you earn interest on $100. If you deposit $10,000, you earn interest on $10,000. There is no threshold you have to cross to unlock the rate.
A few banks do impose minimum balances, usually between $500 and $2,500, but these are less common among online banks. If a bank requires a minimum, they will tell you before you finish opening the account. You can compare options and choose one with no minimum if that matters to your situation.
Key Takeaways
- Most online banks let you open a high yield savings account with no money down, though you'll need to fund it before you can earn interest.
- The interest rate applies to whatever balance you hold, so you don't need a large deposit to benefit from the rate.
- Some banks charge monthly fees if your balance falls below a certain amount, so read the fee schedule before you open.
- You can start with $1 or $100 and add more over time without penalty or rate changes at most institutions.
What happens if you don't meet a minimum balance requirement
If a bank does require a minimum balance and your account drops below it, the most common consequence is a monthly maintenance fee—usually $5 to $10. Some banks waive the fee if you maintain the minimum for just one day of the month, while others require it for the entire statement period. A few banks will close your account if the balance stays too low for too long, though this is rare with savings accounts.
The fee erodes your interest earnings quickly. If you're earning 4% APY on $500 but paying a $10 monthly fee, you're losing money. Before opening an account at a bank with a minimum balance requirement, calculate whether the interest rate is high enough to offset the fee if you can't maintain the minimum.
Banks with no minimum deposit and competitive rates
Several large online banks currently offer high yield rates with no minimum balance requirement. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank are examples, though rates and terms change. Your credit union may also offer a high yield savings option with no minimum.
The rate you receive may depend on your account type, your relationship with the bank, or the amount you deposit, even if there's no stated minimum. Some banks offer a slightly higher rate if you maintain a larger balance, but this is usually disclosed upfront. Check the bank's website or call their customer service line to confirm the current rate and any conditions attached to it.
How to compare accounts when minimums vary
If you're choosing between accounts with different minimum balance requirements, list the minimum, the monthly fee if you fall below it, and the APY. Then calculate your annual earnings on the amount you plan to deposit.
Example: Account A has no minimum and pays 4.5% APY. Account B requires a $2,500 minimum, charges a $10 monthly fee if you fall below it, and pays 4.75% APY. If you plan to deposit $5,000, Account A earns you $225 per year. Account B earns you $237.50 per year but only if you keep $2,500 in it at all times. If you might dip below $2,500, Account B costs you $120 per year in fees, making Account A the better choice.
This comparison takes two minutes and often reveals that the account with the highest advertised rate is not the best choice for your situation.
Opening an account with a small initial deposit
If you want to start with a small amount—$10, $50, or $100—choose a bank with no minimum balance requirement and no monthly fees. You can fund the account through a bank transfer from your checking account, a wire transfer, or sometimes a check deposit. Most transfers take one to three business days to clear.
Once the money arrives, it begins earning interest when ready at the rate posted for your account type. You can add more money whenever you want, and your interest compounds daily or monthly depending on the bank's terms. There is no penalty for adding funds or for keeping a small balance.
When you might want to wait before opening
You don't need to wait for a specific amount to open an account, but you should wait until you have money to deposit. Opening an account with a $0 balance means you're not earning anything, and some banks may close inactive accounts after a period of time—usually six months to a year. If you plan to deposit money within a few weeks, opening now makes sense. If you're months away from having funds to deposit, wait until you're closer.
Also consider the current interest rate environment. Rates change frequently and can move up or down. If rates are rising, opening sooner captures the benefit of future rate increases. If rates are falling, the timing matters less. You can check current rates on bank websites or rate comparison sites to see what's available today.
Frequently Asked Questions
Do I have to keep a certain amount in the account to keep the interest rate?
No. The interest rate applies to whatever balance you hold. If you deposit $100 and the rate is 4.5% APY, you earn interest on that $100. You can withdraw money anytime without losing the rate, though your interest earnings will be lower because your balance is lower.
What if I want to open an account but don't have money to deposit yet?
You can open the account now and fund it later. Most banks let you complete the signup process online, and you have a set number of days (usually 30 to 60) to make your first deposit. After that, the account may be closed if it remains unfunded.
Can I move money between my checking and savings account without penalty?
Yes, at the same bank. You can transfer money between your own accounts as often as you want. Federal rules used to limit savings account transfers, but those limits were removed. Check your bank's terms to confirm, but most online banks allow unlimited transfers between your accounts.
Will opening a high yield 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 this does not show up on your credit report.
What's the difference between a high yield savings account and a money market account?
Both earn interest, but money market accounts sometimes come with a debit card or checkbook, while savings accounts typically don't. Money market accounts may have higher minimum balance requirements. For most people, a high yield savings account is simpler and has lower barriers to entry.
