<< Thanks for the replies yet once again.
But forgive my ignorance... what does "per diem" mean?
Anyway, judging from the numbers and factors. It seems biweekly payments don't really save me much yet adds to the hassle. Hmmm. >>
Per diem is the amount of interest you're paying every day, for instance if your per diem is $2.05 per day and you make a payment once a month your monthly interest charges are $61.50 ($2.05 per day x 30 days), the per diem changes after every payment you make, gradually it goes down a few cents, then more and more until you're paying 1 cent a day then your loan is paid off one day.
Also when you call your bank, ask them of your last 2-3 payments of $400 how much was applied to interest and how much was applied to principal?
So here's a run down of the questions you should ask them:
1) What is my per diem (interest per day)?
2) Of my last 2-3 payments how much was applied to interest and how much to principal?
3) What is my current balance (not payoff), how many payments are left, when does my loan mature?
After asking them these questions, you can plug these figures into a loan calculator, here's the really spiffy part. They have loan calculators which let you run "what if scenarios", for instance, "what if I paid an extra $50 per month or $75 per month, how much interest would that save me and how many months would it reduce the term of my loan by".
Financial calculators are fun!
