<prompt> Human: Took a look at my budget today and really felt like there wasnt much leftover after bills and necessary expenses are paid and a little is put back monthly for car repairs and Christmas gifts say, a few hundred per month. Is there an amount or percentage thats a proper amount to have left over after necessary expenses are taken care of? This would be before contributing to any type of savings account, etc.  <response>: 100 is ideal.0 is not good.Somewhere in the middle is preferable.
