Calculating column/measure that is dependent on itself

I need help calculating starting/ending balances that are dependent on given inputs for the starting year, but use rates applied to previous year balances to form future year ending balances. Pasting in a table from excel, I am given column B's values and all of rows' 2, 3, and 8's values. My goal is to calculate 2023-2027 rows 5-7 and 9.

 

My PBI dataset has the years unpivoted so that I have one Year column instead of individual rows. I have tried to use a calculated column and measure, but I usually run into a circular reference because I cannot force the column/measure to calculate for each year and then use the previous year's value as a starting point. I would prefer to calculate inside the model using measures/columns, but can do a function in power query if needed.

Hi,

Share an MS Excel file with formulas so that your logic can be understood.  How did you arrive at 49,716 in cell B5?

I edited my original post to say that I am given column B's (2022) values, so I know my starting point. I am having difficulties calculating Column C (2023) rows 6,7,9. I included the formulas in the notes column on the far right of the table.
