Ten years ago I was a student in Osaka. I didn’t have a consistent job on the side so my monthly budget was very limited. But I still wanted to enjoy small luxuries like the Korean BBQ joints and bars the city had to offer so I had to devise a way to amass personal allowances on a consistent basis.
I set up an Excel spreadsheet where I had cells for each day of the month that would be filled with daily subtotals. I also wanted to set weekly budgets (mostly because I needed the extra money for weekend parties) so I appended a column that automatically calculated and showed the amount of money I had saved, or exceeded, relative to the weekly budget. I figured the most realistic way would be to start tracking every single expense because then I’d know exactly how much I was spending.
