I disagree. With a 30 year, you are paying more interest than in a 15 year. So, if you compare the total payment, P+I on a 15 yr, with P+I+extra for the same dollar amount, you end up paying more interest with the 30 year, not to mention that the interest amount per year drops faster with a 15 year than a 30 year.
Man, I'm turning into an accountant. Don't know if that's good or bad.
