Ally has no minimum balance requirement for its online savings account

You can open an Ally savings account and maintain it with any balance, including zero dollars. There is no threshold you must keep in the account to avoid fees or account closure. This applies whether you open the account online or over the phone.

The account does charge a monthly maintenance fee of zero dollars — meaning you pay nothing to hold the account open, regardless of how much money sits in it. This is different from many brick-and-mortar banks, which often require $500, $1,000, or more to avoid monthly fees.

Because there is no minimum balance rule, you can use an Ally savings account as a temporary holding place for money in transit, a backup account for emergencies, or a long-term savings vehicle without worrying about falling below a threshold.

Key Takeaways

  • Ally savings accounts have no minimum opening balance and no minimum balance to keep the account open.
  • You will not be charged a monthly maintenance fee, so the account costs nothing to hold even if it sits empty.
  • Interest accrues on whatever balance you maintain, so even small amounts earn money over time.
  • You can withdraw your full balance at any time without penalty, leaving the account at zero if you choose.

How interest works with any balance

Ally pays interest on savings account balances daily and deposits it monthly. The interest rate varies based on market conditions and changes at Ally's discretion — it is not locked in. You earn interest on whatever amount you have in the account, whether that is $1 or $10,000.

Because there is no minimum balance requirement, you benefit from interest even on small deposits. If you keep $50 in the account for a month, you will earn a small amount of interest on that $50. The interest rate is the same whether your balance is $50 or $50,000.

Interest compounds monthly, meaning interest you earn gets added to your balance and then earns interest itself in the following month. Over time, this compounds into a larger amount, but only if you leave the money untouched.

Withdrawals and account activity with low balances

You can withdraw money from your Ally savings account at any time without a penalty, even if you withdraw everything and leave the account empty. Ally does not charge withdrawal fees or restrict how many times you withdraw per month, unlike some savings accounts that limit withdrawals to six per month.

You can also transfer money into the account from an external bank account at any time. Transfers typically take one to two business days to arrive. Because there is no minimum balance, you can transfer in $1 if you want to test the process or move money gradually.

The account stays open as long as you want it open, even if the balance reaches zero and stays there. You do not need to close it or move money elsewhere to avoid fees.

Comparing Ally to other online savings accounts

Most online banks, including Marcus by Goldman Sachs, American Express Personal Savings, and Discover Bank, also have no minimum balance requirement. This is standard for online savings accounts because they have lower overhead costs than physical branches.

Traditional banks with physical locations are more likely to require a minimum balance — often $500 to $2,500 — to waive monthly maintenance fees. Credit unions vary widely; some have no minimum, while others require $25 to $500.

The main difference between Ally and competitors is the interest rate, not the minimum balance rule. Interest rates change frequently and vary by bank, so comparing rates across several banks before opening an account makes sense if you are saving a larger amount.

What happens if you do not use the account

If you open an Ally savings account and never deposit money, the account simply sits empty. Ally will not close it, charge you, or contact you about inactivity. The account remains yours to use whenever you want.

If you deposit money and then do not touch it for months or years, the same applies — no fees, no penalties, no forced closure. The money stays in the account and continues to earn interest at whatever the current rate is.

Some banks close accounts after a period of inactivity, but Ally does not have a stated inactivity policy that results in account closure. However, if you have not logged in or made any transaction in several years, it is worth logging in to confirm the account is still active.

How to open an Ally savings account with no minimum

You can open an Ally savings account online through their website or by calling 1-877-247-2559. The online process takes about 10 minutes and requires your Social Security number, date of birth, address, and employment information.

You do not need to fund the account immediately. You can open it with zero dollars and transfer money in later. If you want to start earning interest right away, you can link an external bank account and transfer funds during the opening process.

Ally will verify your identity and may place a temporary hold on your account while they confirm your information. This usually resolves within one business day, after which you can deposit and withdraw freely.
