Not trying to hijack or supersede anyone's topics here, just figured I'd try to be helpful - this is inspired by "Managing Your Money, Building a Personal Financial Model" and "I Can't Save Money".
This is a budget template I built that I think works pretty well. You can enter your budget by month and expense category, and then track your expenses and income in the "Income & Expenses" tab. Pretty straightforward and dynamic. I generally try to take 10-15 minutes at the end of every week to enter in the appropriate line items and have found it helpful in terms of seeing where I spend more than I'd like.
Hope some people find this helpful.
