My guess is that you have a python data structure that contains the items and the interest. I would extend this data structure to contain the result of the computation, pass it to the view, render it as you did in PHP. If you choose to compute the "current value" in the view, I would not see anything wrong with it, although it is more likely the current value is needed in other places in the program and therefore it should belong to the data structure.
