I've used Quicken for Mac for decades and certainly since our last mortgage was refinanced, about 10 years ago. The program has always properly tracked the division between principal and interest perfectly. Now, in the last two or three months, the split is off and it's driving me nuts to have to correct this calculation when it should be, you know, MATH. I can see in my payment schedule that my final payment is scheduled to be a bizarre amount — namely, that my usual payment is $2,166.24 but that final payment (due in 11/42) is $2.31. That's weird in and of itself. But the principal/interest split is getting off more and more with each month. I see no way to adjust any of this in Quicken. Help?
