I budget for three types of expenses:
(1) the usual, recurring expenses like utilities, cable TV, gym membership, food, and so on.
(2) padding to cover unexpected expenses such as major A/C work, a root canal, a broken TV.
(3) Fun stuff.
I allow $800/mo for (1). That was $600/mo before Katrina, but inflation has been rampant here what with carpetbaggers and opportunists. If I don't use the allotted amount on (1), I will consider something in category (3) or else save the extra.
Category (2) has been running about $650/mo historically, so I allot that much for it. If nothing occurs, I let that pile up. If too much occurs, then any excess from the $800/mo for (1) goes to this fund rather than to (3).
After many years of credit card use, I decided that I prefer to have none.
Every morning over coffee I log into my online bank account. All my bills are on automatic bill pay, so I check them, check the amounts, and think about any that are excessive ("hmm, wonder if I should nudge the thermostat a little?" and so on). I check to see how I am doing at meeting that $800 goal, both for this month and in the long term. If I am behind, guess what? Cut back on (3). I just tell myself that I can get whatever-it-is later, when I have the slack in my budget. Waiting a month or two is no big deal and just allows me to anticipate the desired purchase much more. If the problem continues in the long term, I have to check price increases and consider increasing my budget as I did after Katrina.
Actually, this is all kind of fun for me.
I get a big charge out of making a plan and watching it actually happen right before my eyes!!
I agree so much with those who say the recurring expenses make more difference than you might think.
