<prompt> Human: My wife, family and I have decided to move into a larger home. Ive been in current home for 6 years on a 15 year mortgage. I expected more than a 13 of my principal to be paid down but its only down about 12. Is something wrong with my mortgage or do I not understand how this works?  <response>: Are you familiar with an amortization table? You can find one online on sites like bankrate.com or just google it and itll start to make sense. Enter all your info loan amount, interest rate, term, etc and look at the payment table. Youll see a majority of your payments in the early years go toward interest. Now compare this to a payment in Year 15. Most your interest has already been paid and now the majority of your payment is going toward the principal. Principal vs Interest Yes this sucks and is deflating but its how a mortgage works.
