In the beginning, for me it was cents, then when I really began working hard with making the time to write daily as a commitment, it turned into over a dollar. Last month it was just under $6, so it's slowly growing. It takes patience and time and a lot of work and research and knowledge of SEOs. I had an email from a student from the UK thanking me for some of my hubs because they helped him with his studies. Can't put a price on that.
