Student loan Numbers Through December 2015

I tracked my student loan payoff amounts (somewhat) for 2015.  The total amount owed at the end of each month is shown below.

December 2014: $23,650
February 2015 $22,226 
April 2015: $19,408
May 2015: $18,939
June 2015: $16,632
July 2015: $14,824
August 2015: $12,392
September 2015: $9,999
October 2015: $8,019
November 2015: $5,692
December 2015: $3,844

I paid a total of $20,317.22 to my student loans in 2015, of that amount $506.26 went to interest.  I made my final goal of paying $20,000 to my student loan in 2015!! I'm so excited that I accomplished that goal.  It was a great year for student loan payoff.  My next payment is not due for over 8 years! 

Coming soon, an analysis of how I did on my 2015 goals!
