@xstreetprowl 1. It would be surprising to see that in a 30 year mortgage, more than half is paid after 7 years. You may not have used the right formula. What was the yearly payment? If A=amount of mortgage (410350) P=monthly payment R=1+annual rate (1.065) n=number of years (periods) then using $$\Large AR^n=\frac{P(R^n-1)}{R-1}$$ from which you can solve for the payment P

n=30 (years) to solve for P (yearly payment) The left-hand side shows what is owing, and the right hand side what has been paid. They are equal at n=30 (paid off). At n<30, say 7 years, the difference (left - right) is the balance owing.
