Most high yield savings accounts have no minimum balance to open or maintain, but some banks set minimums between $1 and $25,000
Whether you face a minimum depends entirely on which bank you choose. Online banks—the ones offering the highest rates—almost never require a minimum. Traditional banks and credit unions that offer high yield savings accounts often do, and the amount varies widely. Some set the bar at $1 (which is effectively no barrier). Others require $500, $1,000, $2,500, or even $25,000 to earn the advertised rate.
The minimum matters because it determines whether you can actually use the account. If you have $300 and the account requires $1,000 to open, you cannot use it. If you meet the minimum but fall below it later, the bank may freeze your rate, charge a monthly fee, or close the account. The account terms spell out what happens—and it varies by institution.
Key Takeaways
- Online banks offering the highest rates typically have zero minimum balance requirements to open or maintain an account.
- Traditional banks and credit unions may require $500 to $25,000 to open a high yield savings account or to earn the advertised rate.
- Some banks allow you to open an account with any amount but only pay the high rate if you maintain the stated minimum.
- If your balance drops below the minimum, the bank may reduce your rate, charge a fee, or close the account—check the terms before opening.
- Comparing minimums across banks takes five minutes and can mean the difference between using an account and being locked out of it.
How minimums work in practice
A bank's minimum balance requirement usually applies in one of two ways. The first is a minimum to open: you cannot fund the account unless you deposit at least that amount on day one. The second is a minimum to earn the rate: you can open with $1, but if your balance falls below the stated minimum, the bank drops your interest rate to something much lower—often 0.01% or less.
Some banks use both. They may require $2,500 to open and another $2,500 minimum to keep earning their advertised rate. If you drop to $2,499, you lose the rate. If you drop to $0, the account closes automatically after a set period of inactivity.
A few banks have no minimum at all—not to open, not to earn the rate. These are usually online-only institutions like Marcus, Ally, or American Express Personal Savings. They compete on rate and convenience, not on who can afford the highest barrier to entry.
Where minimums are highest
Credit unions and regional banks are more likely to impose minimums than national online banks. Credit unions often require $500 to $1,000 to open a savings account of any kind, and their high yield versions may be higher. Some require membership in the credit union first, which itself may have a minimum deposit.
Larger traditional banks—Chase, Bank of America, Wells Fargo—offer high yield savings accounts but usually only to customers who already have other accounts with them or who meet wealth thresholds. Their minimums tend to be $10,000 or more. If you do not already bank there, opening a high yield account alone is often not possible.
Online banks and fintech platforms almost never have minimums. If you are shopping for the highest rate and have less than $1,000 to deposit, an online bank is your only realistic option.
What happens if you fall below the minimum
The consequences depend on the bank's terms. Most commonly, the bank reduces your rate to a standard savings rate—often 0.01% or lower—while you remain below the minimum. Your money stays in the account, but you stop earning the high yield rate you signed up for.
Some banks charge a monthly maintenance fee if your balance drops below the minimum. This fee is usually $5 to $10 per month and can wipe out any interest you earn. A few banks will close the account if you fall below the minimum for a set period, usually 30 to 90 days of inactivity or low balance.
Before opening an account, read the fee schedule and account agreement. Search for the words "minimum balance," "below minimum," and "maintenance fee." If the terms are unclear, contact the bank and ask directly: "What happens if my balance drops below the minimum?"
Comparing minimums across banks
| Bank Type | Typical Minimum to Open | Typical Minimum to Earn Rate | Fee if Below Minimum |
|---|---|---|---|
| Online banks | $0 | $0 | None |
| Credit unions | $500–$1,000 | $500–$1,000 | $5–$10/month or rate reduction |
| Regional banks | $1,000–$5,000 | $1,000–$5,000 | $5–$10/month or rate reduction |
| National banks | $10,000–$25,000 | $10,000–$25,000 | $10–$15/month or rate reduction |
These ranges reflect what you will typically encounter, but individual banks vary. The only way to know for certain is to visit the bank's website or call and ask. Most banks list their minimum on the account details page, but some bury it in the full account agreement.
Strategies if you cannot meet the minimum
If you have found a high yield account you like but cannot meet its minimum, you have three options. First, open an account with a bank that has no minimum. This is the simplest path and usually gets you the highest rate anyway, since online banks compete on rate rather than on who can afford the highest barrier.
Second, deposit enough to meet the minimum and keep it there. If the minimum is $1,000 and you have $2,000 total, you can put $1,000 in the high yield account and keep $1,000 in a checking account or another savings account. This locks in the high rate on the portion that meets the minimum.
Third, wait. If you are building savings over time, you may reach the minimum in a few months. In the meantime, keep your money in a no-minimum high yield account. Once you hit the minimum, you can move it to the account you prefer—though you should check whether the rate is still competitive by then, since rates change frequently.
Frequently Asked Questions
Can I open a high yield savings account with $100?
Yes, if you choose an online bank with no minimum. Marcus, Ally, American Express Personal Savings, and many others let you open with any amount. Traditional banks and credit unions usually require at least $500 to $1,000.
What if I meet the minimum when I open but my balance drops later?
Most banks will reduce your interest rate to their standard savings rate, which is much lower. Some charge a monthly fee instead. A few will close the account if you stay below the minimum for 30 to 90 days. Check your account agreement to know which applies to you.
Do I have to keep the minimum in the account forever?
No. Once you open the account, you can withdraw money whenever you want. If you fall below the minimum, the bank may reduce your rate or charge a fee, but you can still access your money. You are not locked in.
Is a high yield account with a $5,000 minimum worth it?
Only if the rate is significantly higher than what you can get with no minimum. Compare the rate at a bank with a $5,000 minimum to the rate at an online bank with no minimum. If the difference is 0.5% or more, the higher rate may justify keeping $5,000 there. If the difference is 0.1%, it probably is not.
Can I use multiple high yield accounts to avoid minimums?
Yes. You can open a no-minimum account at one bank and a minimum-based account at another. This lets you use whichever account makes sense for your balance at any given time. There is no limit to how many savings accounts you can have.
