Personally, I think it is interesting to see what people spend on various things, and we have had a few in the past. The trouble is everything is so subjective, and subject to regional costs, and whether you take a mortgage into retirement, pay your healthcare, etc. For example, this year I have flown halfway across US to Vegas 7times, Aspen skiing for a week,Tahoe, a trip to another lake for a week, and 2 jaunts to Minneapolis. To some that might sound like a jet setter life, but in reality I spent under 50k the last year, and have a house payment, college payment and child support. I just allocate my resources in the manner I want and enjoy.
For me, the best thing to do is analyze your income stream in retirement and make sure that is correct. Also, track your expenses in 2 categories: 1) the essential expenses such as healthcare, food, utilities, etc. 2) non essential expenses such as vacations, entertainment, etc.
There were certain things I had to make sure I had the income for before I retired. Once I was sure my standard of living was covered with $1000 extra a month, I retired. I tracked for 2 years, and felt pretty confident at that time. Plus knowing my child support and college expenses are nearing the end will provide even more bonus income.
