    Are you thinking Net Present Value and related concepts such as discounted cash flow?

    You are the type of what the age is searching for, and what it is afraid it has found. I am so glad that you have never done anything, never carved a statue, or painted a picture, or produced anything outside of yourself! Life has been your art. You have set yourself to music. Your days are your sonnets.

    right here how it goes?

    a homeowner spends €5000 on a new solar panel for there house
    In the first year they see a saving of €400
    the saving increases by 5% each year as fuel prices increase
    What is the payback period on the solar Panel?
