How much do you spend each month on your household budget?I'm relying on a spreadsheet to keep track of my monthly costs - rent, food, utilities, and miscellaneous expenses.For just me in one month, my monthly budget comes to about Y150,000. I cook three meals a day, eat out once a week, and buy clothes and treats (coffee, snacks, presents for people etc.) on that amount. For reference the rent (1LDK apartment built 15 years ago) is Y60,000. What's it like for other solo people? For couples?
