$2 a day or $60 a month for a working individual is comfort life, for a family one needs more.
Rent: Urban - $20 + $5-8 (other expenses). In a rural setting $20 would be fairly comfortable housing.
Food: (rice/wheat bread(roti) + vegetables/dal) - this is considerably 'good' food, 1 person would need ~6 kilo of rice + 2-3 kilo of dal + misc items, cheaper options: $6-7 + cooking gas etc $2
Urban setting would mean travel and other expenses of $10-$15.
So effective a urban individual would hardly have $5 as saving. In a rural setting one can save upto $20.
People buy clothes or other items occasionally. Twice in a year is considered fairly lucky. And you can buy clothing for as less as $1-$2 these days.
