The wife and I plus three Labradors seem to use about 25,000 a month over the last few years. We live quietly and modestly by choice. We shop at Makro, Lotus's and Big C in the main and the only eating out is a local restaurant 2-4 times a week. We cook our own bread, bakery, majority of meals and eat a mainly western diet. If we lived closer to where quality beef/lamb, decent cheese, and burgers/pizza were available I could see a 5,000-8,000 a month increase would likely happen. (Plus an increase in my already excessive weight.) We own our own home and car, don't drink/smoke/gamble/lend to family and have been debt free for a decade.
