So essentially I want to calculate this list with 1% interest compounding annually. Each number is the new balance after a deposit each year. I want 1% interest compounding annually; what is the formula to use to automatically compound the entire column 1% annually if there is one? I could do it slowly 1 cell at a time and re-add all 31 columns but that seems excessive.

Not working for some reason; idk

edit: These are the numbers im adding each year to an account (deposits); but i want to compound them as they accrue and are added; the top numbers were just the numbers added up each year.
