Your bank probably lets you setup a "transfer trigger" that will transfer money automatically when certain conditions are met.

Most big banks offer a way for you to automatically transfer money from your checking account to your savings account whenever certain conditions are met. The specific details of this program vary from bank to bank, but most of them will at least transfer whenever your checking account goes above a certain amount.<br><br>The setup for this can be in the "transfers" tab in your bank's website or app. Mine lets me transfer whenever my balance goes above $1000.<br><br>The money in your savings account probably earns a tiny amount of interest, so you could also put it in a high-yield savings account (if you live in the US), or something like chime (I'm not sure what alternatives exist, outside of the US).<br><br>EDIT: Some people are saying this isn't a "transfer trigger", and I'm sure they're right. I just don't know of a better name for it. Can anyone help me with this?<br><br>EDIT: As mentioned in the comments, some banks will only make the transfer if they're profitable enough, which can often take a few months to happen. If you've set it up and haven't noticed any transfers happening, you might want to look into this.
