THREAD UPDATE:
I recently finished my first month's data dump and processing. It probably took about 30 minutes to copy/paste/process data from 3 credit cards and my checkbook register spreadsheet, including labeling each expense with a spending category number (4 for Home Maintenance, 7 for gasoline, 12 for groceries, etc). That 30 minutes includes figuring out how to do what I was trying to do, doing it, then reviewing the data. Outside of the 30 minutes at month end, I spent maybe another 15-30 minutes during the month manually entering a few transactions in the "cash" category, as well as breaking out certain expenses from the walmart receipt (like lawncare stuff = home maintenance, and shoes/clothes = clothing, not groceries/household). Splitting the walmart receipt out wasn't too hard, since it was usually 90% groceries/household stuff and 10% other miscellaneous stuff that fit into a particular category. I'm not sure if I will continue doing the monthly data dump or go to quarterly. I would get a slight economy of scale by doing a larger batch of data less frequently. Although I might just create a macro to do the majority of the data manipulation.
Cash tracking went well. We had $6 unaccounted for. I recall there was something smallish of a few dollars that DW told me about (breakfast??), and I told DW not to worry about keeping track of purchases that small. And a $5 parking fee that I charged to a CC and then received cash reimbursement for a couple bucks more than the $5. And last night DW reminded me of a $10 bill she slid to our nephew for his bday that she swears she told me about before (she didn't!
). Not a lot of slippage at this point, and April was a fairly typical month in terms of spending. DW has bought into the expense tracking, mainly because it requires her to do very little other than tell me about the handful of cash transactions she has each month. Again, if we miss one or two small ones, it won't really matter and gets reconciled and recorded as a "cash" expense on a monthly basis.
As usual, some expenses were larger than normal (dental and home maintenance/repaid/lawncare) and some smaller than normal (car maintenance and dining out). It probably balanced out to an average month.
Basic spending just over $1700 or $21,000 on an annualized basis. That doesn't include the mortgage or student loans or a 1 time prepayment of a beach house rental (vacation category). And it doesn't include around $2500 a year in
lumpy expenses like property tax and insurance.
For FIRE projection purposes, that $21,000 would be closer to $24,000 a year, minus some spending in the gas category, plus a lot more spending in the health insurance and particularly travel/vacation category.
So we are feeling pretty good about our current basic spending and it is not way out of line from what I was expecting it to be based on when I last looked at it years ago. It will be interesting to get a whole year of data in.
I'll have to post the expense tracking spreadsheet I built some time (it is at home right now).
