Yes, and mostly. I budget/track with Mint. I've gotten really good recently setting budgets in Mint and even manipulating them throughout the month when needed. It helps that I love numbers and analyzing data. The reason I do it to help my wife and I understand where the money goes. I'm not sure how well it works though. My DW has trouble with the concept of spending only to the budget. For example, if she overspends on groceries she doesn't understand that we may need to take that money out of the new tires fund.
We are trying out something new this month. The account is only to be used for categories that we agree on such as groceries, gas, medical. Anything outside of those categories we either need to discuss before purchase or it can come out of cash funds (discretionary). I'm hoping the cash helps us realize that we only have a finite amount of money to spend and if we spend it all in the first week we won't have any more.
Tracking helps us understand where we can and cannot cut expenses. For example, if we spend $300 on fuel every month and we group errands and only drive to work, soccer practice, etc.. then we cannot go lower than $300. And if fuel costs spike 10% we will need to add 10% to that budget. Same goes for food. We've been trying to get our spending down in this category but we can't do that by under budgeting. Instead, we need to actively create meal plans and stick to the grocery lists. So gas and food I try to over budget for. Any extra at the end of the month we then place that in one of our goals categories (vacation, pool (I know face punch me), newsed car, etc...)
What taught me the most about budgets is the book All Your Worth. I really like the 50/20/30 rule that they lay out. It's a simple set it and forget it budget. However, as a budding mustachian I do more than the 20% for savings. But the simple idea that I go by is pay your bills, then pay your future you (savings), then have fun with the rest. My bills are autopay, my 401k and IRA are auto funded.
