I'm not sure why or to whom this would be interesting; I'm writing it up for me and future reference, but I don't have any good reason to lock it, so.
So my budget in Oakland looks like this: ~$12K a year on rent, food via cash or bank card of unknown amount (probably $3-4K), electric/phone bills paid via bank account ($1-2K?) and then various random more-or-less discretionary purchases via credit card. Figuring on discretionary purchases as being ~$5K, that works out to around $22K, which makes sense; I've often tired to target around $2K/month.
Anyway, rather than guess about the discretionary purchases, I took my credit card bills for the last couple of years and found the following info (summarized from a more detailed spreadsheet).
2005: $ 5000
I actually assigned purchases to the payment-date-due on the statement (rather than the date of the purchase), because that date was most visible on the statement; so the purchases are slightly time-shifted--2006 actually includes purchases made in December 2005.
Categorical breakdown of the last 27 months (missing one month):
$7200 computer hardware $4300 newegg $2895 dell $1847 audio recording hardware/software (protools etc.) $ 250 videogames $2380 professional $ 895 game developer's conference $ 705 licensed art assets $ 775 game/graphics programming books $2100 airfare for multiple trips $ 500 netflix $1265 dvds $ 919 deepdiscountdvd $ 345 amazon $1185 cds $ 663 deepdiscountcd $ 522 amazon $ 614 ipod + many headphones $ 350 archos $ 422 internet hosting, domains, etc. $ 288 webcomics books $ 225 amazon books ($100 for Calvin&Hobbes alone) $1800 misc uncategorized
Looking to the future, I hope to return to 2005 levels of expenditure. A certain amount of the excess in 2006 was 'money burning a hole in my pocket'; I knew I had a lot money and could afford stuff, so I splurged on CDs and DVDs; I'll have to be careful to rein that back in.
But most of the expenses should be fairly non-repeatable. A lot of this stuff was computer hardware, which I should be set with for a while (purchases in the last 27 months include 3 LCD monitors, 2 desktop computers, and a laptop). I don't need to buy more game programming books (I didn't really need to buy these, but I figured it would be nice to have them just in case, and there was no reason to wait--I splurged on amazon a ton during my three-month trial of Amazon prime, but only stuff I would have bought Amazon prime or not). I upgraded the ipod due to space issues, but now I have a 60GB ipod and 30GB of mp3s so size-wise it should last the rest of my life (though the battery won't).
