I also use spreadsheet. Once I got my salary, I make a plan for my expenses for the month. I always leave a buffer of 300 and transfer the remaining amount directly to my deposit account. Once a week or biweekly, I review the plan to check if my remaining balance will cover all upcoming expenses. If not, I use my buffer.
