1. Food/restaurants : $424 per month, or $14 per day ($4 per day for restaurant, $10 per day for foodcourt/hawker/coffee shops)
2. Utilities bill: $50 per month for my share, so it's about $100 household (subsidies included)
3. Clothes/shoes: $30 per month
4. Gifts/ang bao for others: $126 per month
5. Mobile phone: $42 per month
6. Household internet: $45 per month
