Considering how I thought the month was going to go, I feel pretty good. I started out the month with a weekend in Boston, spent a weekend in NYC and finished the month in Hawaii, but still managed to keep my costs under control. My Miscellaneous category was a little high, but there were a number of gifts, with graduations, birthdays, father's day and a wedding. I am especially pleased with my food - dining in category. For less than $70 spent on food, I managed to provide myself with 22 days of food. Close to $3/day is very efficient eating. Other than that, I did actually get my prescription filled, but that only happens every few months, so hopefully things will generally be similar to this in months to come.
Even better, when I looked at how much I've spent over the last 4 months (since I started tracking my spending) and compared it to my net income, it came out to 44%. This is in addition to the 6% of pretax income going into my 401k, and the donations to my HSA. I'm feeling pretty good about my saving.
