Acorns has an agreement with some of the major banks, where if a deposit is attempted that may put your Primary Checking account under a certain amount (usually around $25), our system will flag it as a deposit that may not complete and it is automatically canceled.
For example, if there is $30 in the Funding Source and you try to invest $15, the deposit will be canceled. Keep in mind that this is only at the exact time the system tries to make the investment, and if you have a pending deposit to your checking account it may not register quite yet. This doesn’t actually put a suspension on your account, it just cancels that single investment. If a recent deposit was made into your checking account, it can take Acorns anywhere from 24-48 hours to read the accurate balance and release the pause.
However, keep in mind this is not 100% effective protection against overdrafts due to deposit processing times (which takes 1-3 business days). If there is an investment triggered on Tuesday and it is not identified as a problem, it might not be pulled from the checking account until Thursday. If there are numerous other transactions within your checking account between that Tuesday and Thursday, this may cause an overdraft.
