How to Track Your Expenses
Date Posted: October 26th, 2009
The book, Your Money or Your Life (YMOYL), is great, but it doesn’t give you specific instructions on how to track your spending. The reason they give is that you need to come up with your own system, but it still helps to see exactly how people do this tracking without it eating their lives. This post will show you the how Aaron and I track our expenses for the YMOYL system. Chances are your system won’t work exactly like this one, but maybe you can get some ideas of how we do things.
Track all expenses for the Month
The way we do this is by:
- Keeping all our receipts
- Writing down non-receipt expenses (like farmer’s market, parking, etc.)
- Leave a voice note when I don’t have my planner
I take my planner most places, and put receipts inside a little pouch in the planner so that my wallet doesn’t get bulky. Sometimes I’ll put the receipts in the wallet temporarily and then transfer them to the planner later. Voice notes get transferred to the ledger in the planner.
Transfer to Spreadsheet
Aaron and I have a Google Docs spreadsheet we share for keeping track of our expenses. Google Docs is great for a few reasons:
- Easy collaboration — we can both update the file at the same time
- Online — don’t have to be on a specific computer; don’t have to merge two separate files
- Easy to import into mysql — Good for interpreting the data later
We update the spreadsheet about once a week. This is one of those nice tasks that doesn’t require a lot of mental effort.
Our spreadsheet has the following fields:
- Date The date the item(s) were bought.
- Store Where did we buy said item(s)?
- Item What did we buy? I don’t usually list every item individually unless it’s only a couple of items. If I buy a bunch of ingredients for a recipe I’ll just write “groceries” here.
- Tag What category does this fit into? Sometimes a single receipt will be in several categories. Each category gets its own row. If I bought shampoo and apples at the Kroger, there’ll be one line with shampoo (and its category) and another with apples (and its category)
- Subcategory Some categories can be further split. Wedding, for instance, is a big category. I want to know how much we’re spending total on the wedding. However, I also want to know how much we’re spending in different areas of the wedding (hall, favors, music, etc.). Not all categories have subcategories
- Amount How much did it cost? I include tax in this.
- Source Where did the money come from? The shared credit card? My personal credit card? Cash? The change we keep in the car? Useful for checking against our account statements.
- Cleared? Has it cleared yet? Have the checks been cashed? We only check this at the end of the month.
And that’s basically it for the initial expense tracking. Later this week I’ll show you how we use MySQL to get some insight into how we spend our money.
