Discover doesn't require a minimum balance to open or keep a savings account

You can open a Discover savings account with any amount of money — even $1 — and you won't lose the account if your balance drops to zero. There's no monthly fee, no penalty for low balances, and no requirement to maintain a certain amount to earn interest on what you do have.

This matters because many traditional banks require you to keep $500, $1,000, or more in savings to avoid monthly fees or to earn interest at all. Discover's approach is different: they make money from lending, not from charging you for having a small balance. That's why they can afford to let you start small.

Key Takeaways

  • Discover savings accounts have no minimum opening balance and no minimum balance requirement to keep the account open.
  • You earn interest on every dollar in the account, regardless of how much you have, as long as the account is open.
  • There are no monthly maintenance fees, and your account won't be closed for having a zero balance.
  • Interest rates change over time based on market conditions, so the rate you see today may be different in three months.

How interest works when you have a small balance

Interest is money the bank pays you for letting them use your money. Discover calculates interest based on your Annual Percentage Yield (APY) — the percentage rate they advertise — and applies it to whatever balance you have, even if it's $5.

If you have $100 in the account and the APY is 4.50%, you'll earn about $4.50 per year on that $100. If you have $10, you'll earn about $0.45 per year. The interest posts to your account monthly, so you see it grow over time. You don't have to do anything to earn it — it happens automatically as long as your account is open.

The APY changes based on what the Federal Reserve does with interest rates. When rates go up, Discover usually raises their APY. When rates fall, so does theirs. This is why the rate you see when you open the account may not be the rate you earn six months later.

When a zero balance might cause problems

Discover won't close your account for having $0, but there are two situations where a low or empty balance can affect you. First, if you have a debit card linked to the account and you try to withdraw more than you have, the transaction will be declined. Second, if you don't use the account for a very long time — typically several years — Discover may close it due to inactivity, though this is rare.

The best practice is to keep at least a small amount in the account if you plan to use it regularly. Even $25 or $50 keeps the account active and lets you earn a little interest while you're building your emergency fund.

How to open a Discover savings account with little money

You can open an account online in about 10 minutes. You'll need a Social Security number, a valid government ID, and a way to fund the account — usually a bank transfer from another bank or a debit card. You can start with whatever amount you want to deposit, even if it's just $1.

After you open the account, you can add money whenever you're ready through bank transfers, direct deposit, or by mailing a check. There's no rush to reach any particular balance, and no penalty if you add money slowly over time.

Comparing Discover to other banks' minimum balance rules

Many traditional banks and credit unions have minimum balance requirements. Some require $500 to avoid a monthly fee. Others require $1,000 or more to earn any interest at all. A few online banks, like Discover, have no minimum at all.

If you're choosing between banks and you don't have much money to start with, Discover's no-minimum approach means you can begin saving without worrying about fees eating into a small balance. You also won't lose money by keeping your account open while you save up.

What happens if you close the account

If you decide to close your Discover savings account, you'll receive any remaining balance — even if it's just a few dollars — either by check or by transfer to another bank account. There's no fee to close the account, and you can do it online or by phone.

Discover will also send you a 1099-INT form at tax time if you earned $10 or more in interest during the year. This is normal and expected; you'll report this interest as income on your tax return.

Frequently Asked Questions

Can I open a Discover savings account with $0?

You need to deposit at least some money to open the account — you can't create an empty account. However, you can deposit as little as $1, and many people do. After the account is open, you can let the balance drop to $0 without penalty.

Will Discover close my account if I don't use it?

Discover may close accounts that show no activity for several years, though this is uncommon. If you want to keep the account open, deposit or withdraw money at least once every year or two. Even a small transfer counts as activity.

Do I earn interest on a $0 balance?

No. Interest is only paid on the money you actually have in the account. If your balance is $0, you earn $0 in interest. Once you deposit money, you start earning interest when ready.

What if the interest rate drops after I open my account?

Your rate will change along with Discover's rates. You don't have to do anything — Discover adjusts the rate on all savings accounts automatically. You can check your current rate anytime by logging into your account online.

Can I use a debit card to withdraw from a $0 balance?

No. If you try to withdraw more than you have, the transaction will be declined. You'll need to deposit money first before you can withdraw it.
