Trouble sticking to a budget when using credit cards for day to day transactions?
First of all, I have to recognize up front that my "spending personality" is frugal. I don't recreational shop, and I save a lot of my total income. Building a budget and sticking to it is difficult, especially for people who are closer to living paycheck to paycheck than I. Theoretically, it should be easy to stick to a budget by overestimating expenses, but for many people planning to spend more than necessary isn't a luxury available. That said, I have a system that works for me, maybe it can work for you. This system lets me see how much I have to spend, and close to optimally arranges assets. As you can see, this system relies on some pretty strong upfront planning and adherence to the plan. And what you might not realize is that you can deviate from the plan in two ways: by spending variations and by timing variations. Credit should really help with a lot of the timing variations; it takes a series of expenses and translates them into one lump payment every month.  As for spending variations, like spending 20 dollars for lunch when you only budgeted 5, it turns out this technique helps a lot. Some academic work suggests that spending with plastic is more likely to blow your budget than cash, unless you make detailed plans. But it sounds like your main problem is knowing whether you can afford to splurge. And the future minimum balance of your checking account can be your splurge number.
