<prompt> Human: Im on a 30 year fixed loan. 130,000 remaining balance. 3.75 interest. Monthly payments are about 1,050. We pay approximately 2,100 per month. Weve made 33 payments so far. This Serbs easy enough to figure out, but I cant.  <response>: Bankrate.com has some really good calculators. You can enter your initial loan amount and rate, add your extra payments and it will show you how fast it will pay off. I tried for you guessing an initial balance of 165K and adding 1000 per month. I got that it would pay off in a little over 9 years. Try the amortization calculator, it will show you exactly when you will pay it off if you keep up your payments.
