States are different and even the trustee you get may not consider some things, but here is what I included for expenses in my BK7.
Rent or home mortage
Electricity and heating fuel
water and sewer
telephone (included cell phone here)
cable
garbage
internet
home maintence (repairs and upkeep)
food
clothing
laundry and dry cleaning
transportation (not including car payments)
medical and dental expenses
recreation, clubs and entertainment, newspapers, magazines, etc.
charitable contributions
insurance (not deducted from wages or included in home mortage payments)
installment payments (this is where my student loan payment went)
alimony, maintenance or support paid to others
payments for support of additional dependents not living at your home
regular payments from operation of business, profession, or farm
then there was a place for Other - my lawyer added personal care/hair cuts and school lunch here.
Amounts will be different depending on the area you live in. The trustee I had lived in the same area, so he questioned those people who had really high amounts. One couple was ordered to provide their heat/electric bills for the past year.
