I am trying to create a rolling budget vs actual file using the information attached. I want to spread the difference on a per month basis throughout the remaining months. For example the budget in January 2013 is 19415 which is 1618 per month. With that, there is a 721 undercharge versus budget (2339 - 1618 = 721). I want the 721 to spread out through the remaining 11 months on top of per month budget in the remaining months. Is there a way to do this? I tried making a variance column and spreading it but I was curious if there was a better way. Budget.xlsx
