    Using jQuery, I made this. Easy.

    Type in the amount, get the answer (85% of the amount) and get the remainder (left over, 15%).

    I would go through the whole isNaN process with you (type a character in to the input…) but it’s a tricky explanation for my brain at this time of night.

    :)
