When doing the 15 year mortgage vs the 30 year mortgage spreadsheets I found that with the 15 year mortgage we are paying twice the amount monthly then we would pay with the 30 year mortgage, which I found to be interesting. With the 30 year mortgage we are still going to pay more overall then with the 15 year mortgage. The 15 year took 180 months to pay off while the 30 year took 360 months.
