<prompt> Human: Im new to using mint.com to track my expenses. I try to re-visit my budget at the end of the month to see where I can save some money. Each month, though, I find myself setting aside a pretty large amount of money 200 - 250 just to cover everything else. For me, this generally includes gifts, lyftuber to the airport, or other things that only happen or twice a year. I know that mint has some features to set a budget only for that month, or to rollover your budget, but I havent been so good at forecasting these expenses. I also feel like the money isnt well budgeted if I dont end up using the rollover... its a little irrational, I know... Does anyone have advice on how to handle everything else? What do you do?  <response>: I had the same issue, so I left a buffer of 200month in my budget. But I didnt like that, because I felt like it wasnt being tracked. So I have started giving myself a 200month allowance, and I budget that out. I allow myself X amount for things I know Ill need haircut, personal hygiene, oil change, etc and then I can use the leftover for whatever I want a night out, a new shirt, savings.Now I just leave a buffer of about 15-20 due to some things varying in cost. For example, electric bill, gas usage, I didnt realize we were out of cat food, etc.
