I’ve developed a method of tracking those quarterly/yearly bills that don’t neatly fit into You Need A Budget’s focus on monthly scheduling. It’s really simple.
As you can see in the above screenshot, I list each of these quarterly/yearly bills in YNAB. In their title, I put when they come do (Yr for Year, Q for Quarterly) and then how much per month I need to set aside.
This makes it incredibly simple to budget every month. Glance at the Car Registration line, know it is $13 a month, and budget that amount. Done.
