Definition of Iteration:-
It is the repeated calculation of a worksheet until a specific numeric condition is met. Excel cannot automatically calculate a formula that refers to the cell — either directly or indirectly — that contains the formula. This is called a circular reference. If a formula refers back to one of its cells, you must determine how many times the formula should recalculate. Circular references can iterate indefinitely. However, you can control the maximum number of iterations and the amount of acceptable change.
The Enable Iterative calculations option allows us to do so.
This video will help you to do iterations in excel. Its pretty easy. To enable the management of iterative calculations, the Formulas tab in the Excel Options dialog box offers two controls: Maximum Iterations This value is the number of iterations after which Excel must stop the calculation if it hasn’t yet converged to a solution. The default value is 100. Options, check the Iteration box, and press OK. In column A, next to your original formula, enter either TRUE to enable automatic recalculation or FALSE to disable it. In place of your original formula in B3 (=NOW), use the IF and NOW functions as shown in the following formula.
Go to File > Options.
Excel Options dialog box will appear. Click Formula and tick the checkbox enable iterative calculations and click OK.
Now perform the Iterative option in Excel.
Use the formula in A1 cell
Use the formula in A2 cell
As you can see the blue arrow pointing towards each other shows that the values of both cells depend on each other’s value.
Hope you will be performing more and more functions now. Please state that your query down in the comment box. We will help you.

How To Do Calculations In Excel
I was thinking that I could mark the vital 'calculation' worksheets (e.g. with a '1' in cell A1), then I could develop a procedure to first turns calculations to 'manual', then goes through each worksheet of the workbook and only enables calculations in those worksheets marked with a '1'. Then after performing all the solving, I could turn calculations back to 'automatic'. I am not sure if my idea is the best way to go about this, nor exactly how I would write this code (I am still a novice, but learning every day!).
Any help would be appreciated.
Thanks.
