Hi all,
Just started using YNAB and trying to wrap my head around how to use it. Right now, I’ve created categories and assigned money to all the bills I’ll need to pay this month. However, some of these bills won’t be paid until my second paycheck of the month. Because of this, my ready to assign is in the negative. I know YNAB is meant to account for the money you have on hand, so how do you all budget for the entire month using your expected monthly income? Am I going about this wrong?
Thanks!
