Can You Deposit a $100 Bill in an ATM?

Yes, you can deposit a $100 bill in most ATM machines—no problem. While policies can vary slightly by bank, the majority of financial institutions allow cash deposits of any denomination through their ATMs, and there’s typically no upper limit on the amount you can deposit at once.

How does it work? Modern ATMs are equipped with advanced scanning technology that can recognize and validate higher-denomination bills like $100s just as easily as smaller ones. As long as the bill is in decent condition—meaning it’s not torn, folded beyond recognition, or heavily soiled—the machine should accept it without issue.

That said, not all ATMs are created equal. Some older models or third-party machines (like those in convenience stores or gas stations) might have restrictions or lack the capability to process larger bills. It’s always a good idea to use an ATM operated by your own bank, especially if you’re depositing a significant amount. These machines are more likely to support full deposit functionality, including cash acceptance and immediate balance updates.

Another thing to keep in mind: while the ATM may accept your $100 bill, some banks place temporary holds on large cash deposits as a fraud prevention measure. This means the funds might not be fully available right away, even if the deposit is processed instantly.

For frequent large deposits, it’s worth checking with your bank about any specific policies or preferred methods—some institutions encourage in-branch drops for very large sums. But for most everyday situations, dropping a $100 bill into your bank’s ATM is perfectly fine and a quick way to handle your deposit.
