User Defined Function to work as calculator

Hi,
In my actual workbook, resulting output cells when through lots of calculation, user defined functions, selection, and optimization. And it has become complex to compare iterations.
One thing I can do is, I can put input parameter to so called calculator, and take output. The same I did using micro, I want to make out the same by using function.
I had attached a file in which micro selects input (Select Range) and result range (Where I will put function).
Thanks for your valuable efforts.
