Hi Nderon Hiseni,
I suggest you should create calculated field in list.
You can apply formula to your field, whose result may or may not be dependent on other column in list.
My suggestion is
1. Create calculated column manually(possible with c# too) in list from advance setting of list.
2. Apply your formula
3. Add column in View
Work Done !!!!

Note : Out of box is always better than customization, it minimizes bug possibility.
