In the comments on my December 2009 net worth post, someone asked about the change in my net worth since 2003 and whether I’d gotten a higher paying job or had changed any of my spending habits to enable my net worth to grow as it did. It prompted me to tackle a project I’d been thinking about for a while: a long-term analysis of my income vs. expenses.
2003 is the first year for which I have full data in Quicken so I looked at that seven year window, and the results were quite interesting! First, let’s just look at after-tax income vs. expenses (click on image for larger view):
I thought it would be easiest to take taxes totally out of the picture, so my income is net after all those deductions, and the taxes paid are also taken out of my expenses. (I also backed out my tax refunds from the previous year’s taxes paid.) Income includes salary, bonus, gifts received and interest earned on bank accounts. It does not include dividends and investment gains as those are reinvested into my investment accounts.
As the graph shows, my income has been gradually increasing, and my expenses have been much more flat, and tending to increase in proportion to my income– just what I wanted to see!
So what made up my expenses? First of all, let me explain the category definitions here, as I’ve grouped things slightly differently than in previous expense breakdowns.
In the chart below, I’m including taxes again just to get the full picture, though again the refunds have been backed out of the previous year’s taxes paid. The next largest expense is housing.
I then did another chart of the expenses without housing or taxes, so you could get a larger view of all the types of expenses that are more variable and controllable. Here, I tried to order the different expense categories so that the bottom of each bar is the stuff that stayed really steady from year to year, with the things that changed the most on the top. It’s amazing how consistent some things are!
But here’s the best part: the bottom line. That differential between income and expenses is all savings that went into my 401k and other savings and investments accounts (and this time I DID back out all the the one-time condo purchase expenses, including about $75,000 that went into home equity, so I still “have” some of that money in a different way).
It’s great to be able to say that I saved more in 2009 than I ever have before:
| 2003 | $27,558 |
| 2004 | $34,664 |
| 2005 | $5,210 |
| 2006 | $-13,429 |
| 2007 | $29,699 |
| 2008 | $35,559 |
| 2009 | $43,214 |
I’m sure I’ll keep staring at all this data and digging into individual years and categories to see more detail– it is weirdly fascinating! The whole thing was fun to pull together and I highly recommend that you try it for yourself!
