<prompt> Human: Im asking more for things like gas and electric, which change every month. Sometimes the bill will be a drastic change, such as going from warm weather to cold weather. So how do you effectively budget for that? I searched for it on here, and did a Google search as well, and didnt really find a response that answered it. I am trying to put together a budget for my SO and I, and I always seem to budget for the utilities wrong and its starting to frustrate me. Thanks in advance guys.  <response>: Always put away a certain amount. Our bill varies between 150-400 so we always assume its going to be about 350. That way if its less theres a little more cushion in your wallet, if its more you should have cushion left over from a previous low month.
