The Big Bank Challenge is a way to test whether you can manage a checking account before you commit to one

The Big Bank Challenge is a short trial period — usually 30 to 90 days — that some banks offer to let you use a checking account without the full commitment or the risk of overdraft fees. During the challenge, the bank turns off overdraft protection and declines transactions that would put you in the negative, rather than charging you a fee. You get to see how the account works, whether the app is straightforward to use, and whether the bank's customer service works for you.

It is designed for people who are new to banking, returning to banking after a gap, or switching from a bank that did not work well for them. The idea is straightforward: you should not have to pay fees to find out whether an account is right for you.

Not all banks offer this. The banks that do — including Chime, LendingClub, and some credit unions — advertise it as a selling point because they know that once you have used an account successfully, you are more likely to stay.

Key Takeaways

  • During a Big Bank Challenge, your debit card transactions are declined if you do not have enough money, instead of charging you an overdraft fee.
  • The trial period usually lasts 30 to 90 days, and you can close the account without penalty if it does not work for you.
  • You still need to provide identification and proof of address to open the account, just as you would with any checking account.
  • Not every bank offers this feature, so you will need to ask or check the bank's website to see if they do.
  • After the trial ends, the account works like a regular checking account, and overdraft fees may explore if you go negative.

How the trial period protects you from overdraft fees

Overdraft fees are charges the bank takes when you spend more money than you have in your account. A typical overdraft fee is $30 to $35 per transaction, and they can add up quickly if you make several purchases in one day.

During the Big Bank Challenge, the bank does not charge these fees. Instead, when you try to spend money you do not have, the transaction is straightforward declined — like when a store's card reader says "declined" and you have to use a different payment method or put something back. You see the decline happen in real time, usually on your phone, so you know when ready that you have run out of money.

This matters because it lets you learn how to manage your balance without the financial shock of unexpected fees. Many people new to banking do not realize how quickly overdraft fees can turn a small mistake into a big problem.

What happens when the challenge period ends

When your trial period is over — whether that is 30, 60, or 90 days depending on the bank — the account converts to a regular checking account. Overdraft protection is turned back on, which means the bank will now charge you a fee if you go negative.

You do not have to do anything to make this happen. It is automatic. If you do not want the account after the trial, you can close it before the conversion date. Most banks that offer the challenge let you close without penalty, but check the terms to be sure.

If you decide to keep the account, you now know how it works and whether you trust the bank. The goal is that by then, you have built the habit of checking your balance before you spend, so overdraft fees become unlikely.

Which banks offer the Big Bank Challenge

Chime, a digital bank, popularized this feature and still offers it. LendingClub also runs a version of it. Some credit unions and smaller regional banks have introduced similar programs, though they may call it by a different name.

The feature is not standard across all banks. Large traditional banks like Chase, Bank of America, and Wells Fargo do not typically offer a trial period without overdraft fees. If you are interested in this option, you will need to check the bank's website or call and ask whether they offer it.

When you are comparing banks, this is one question worth asking — especially if you are new to banking or have had trouble with overdraft fees in the past.

What you still need to provide to open an account

The Big Bank Challenge removes the risk of overdraft fees, but it does not remove the standard requirements for opening a checking account. You will still need to provide a government-issued photo ID (a driver's license, passport, or state ID card) and proof of your address.

Proof of address can be a utility bill, a lease, a mortgage statement, or a piece of mail from a government agency — something dated within the last 60 days that shows your name and current address. Some banks accept a bank statement or credit card statement instead.

You will also need to provide your Social Security number so the bank can run a background check. This is standard for all checking accounts, not just those with a trial period.

How the challenge differs from a regular checking account

The main difference is what happens when you run out of money. In a regular checking account, the bank covers the transaction and charges you a fee. In the Big Bank Challenge, the bank declines the transaction instead, and you pay nothing.

Everything else works the same: you get a debit card, online banking, direct deposit, the ability to write checks (if the bank offers them), and access to customer service. You can deposit money, withdraw money, and transfer between accounts just as you would in any other account.

The challenge is not a limited version of banking. It is full banking with one safety feature turned on: the bank will not let you go negative.

Why banks offer this and what they get out of it

Banks offer the Big Bank Challenge because they want you to become a customer. If you have a good experience during the trial, you are likely to keep the account open and use it for years. That is worth more to the bank than the overdraft fees they would have charged you during those first 30 to 90 days.

It is also good business for the bank because customers who successfully manage their accounts during the trial are less likely to overdraft later. They have learned the habit of checking their balance, and they are more confident using the bank's app and services.

For you, the benefit is clear: you get to test-drive the account without financial risk.

Frequently Asked Questions

Can I use my debit card during the challenge period?

Yes. You can use your debit card for purchases and ATM withdrawals just as you normally would. The only difference is that if you do not have enough money, the transaction will be declined instead of charging you a fee.

What if I close the account during the trial?

Most banks that offer the Big Bank Challenge let you close without penalty during the trial period. Check the terms when you open the account to confirm, but this is standard practice. You can withdraw any remaining balance and close the account online or by calling customer service.

Do I have to pay anything to open an account with the Big Bank Challenge?

No. The account itself is free, and the challenge period is free. Some banks charge monthly maintenance fees after the trial ends, but many do not. Check the bank's fee schedule before you open the account.

What happens to my money if I close the account?

Your money stays yours. When you close the account, you can transfer the balance to another bank account or withdraw it as cash. The bank does not keep any of it.

Can I extend the challenge period if I need more time?

Most banks do not extend the trial period. Once the set time is up, the account converts to a regular checking account with overdraft fees. If you are not ready, you can close the account before the conversion date and open a new one elsewhere.
