Just realized most people don't actually know how much money you can deposit in an ATM. I was trying to deposit some cash yesterday and got curious about the limits.

Turns out there's no universal rule—it's totally up to your bank. Some banks don't have a dollar limit at all, but they might cap how many individual bills you can deposit. Like, Wells Fargo lets you deposit up to 30 bills and checks combined in one transaction. Capital One has a one-time limit of $5,000. Pretty wild that they're different, right?

The process is pretty straightforward though. You just need to find an ATM that actually accepts deposits (not all do), insert your card, select deposit, and feed in your cash. Most modern ATMs don't even need envelopes anymore. The tricky part is figuring out how much money you can deposit in an atm at YOUR specific bank because the limits vary so much.

One thing I didn't expect—if you use an out-of-network ATM, it can take up to four business days for the money to show up. In-network deposits usually hit the same day or next day. And yeah, you might get charged a fee for using someone else's ATM too.

If you bank online, good luck. Most online banks don't have ATM deposit options at all. Some have workarounds like mobile check deposits, but cash deposits are pretty limited.

Before you go deposit anything, just check your bank's app or website to see which ATMs accept deposits and what your specific limits are. Saves a lot of headaches.
