2010 Update

The CBO recently produced their Monthly Budget Review for 2010, so I decided to try to compare how close my estimates were. One thing that is evident is that the defition of Mandatory Spending v. Discretionary Spending isn't clear. It's still interesting to compare the actual v. estimates.

The 2010 extrap. column is the extrapolation from the first 9 months to the full 12 months. Spending is lower than the budgeted amount. I believe agencies have to spend the budgeted amount or they will lose out in future budgets, so spending is likely to increase in the last 3 months of FY 2010.

Category	2010 YTD	2010 extrap.	2010 Budget	My 2010 est.
Revenue	1597	2129	2381	2118
Mandatory	1051	1401	2020	2034
Discretionary	1379	1839	1368	1375
Interest	172	229	164	209
Total Spending	2602	3469	3552	3618
Deficit	-1005	-1340	-1171	-1500

Edit: Another source shows total spending for 2010 budgeted at $3,721B.
