Updating a group of cells on several sheets at the same time

Hello all,

On Google Sheets - I have a budget in calendar format with a separate sheet for each month, with 3 columns out to the side on each monthly sheet that reflect our regularly reoccurring bills that I can just copy and paste into the the calendar. From time to time those columns change as expenses change etc. Is there a way to be able to update those 3 columns from any sheet in the budget that will update each sheet after that one, including deleting cells, changing values etc.? Basically so that I don't have to go copy and paste on each subsequent sheet if say, our phone bill goes up, or I pay an item off, etc.

Done, and thank you!
