Over the past couple of weeks I’ve spent some time making this auto loan calculator template for you. Well, I guess its not really a template, but a tool! What you do is put in your information about your car loan on the first page like the purchase price and the sales tax. On the second page you’ll add details like the loan amount, and the frequency of payments. It will then amortize the loan and give you payment details. It will also allow you to add in additional payments and it calculates how much interest you’ll save because of your additional payments. Overall its a pretty useful tool and I hope that you find it so. Please feel free to tell me what you think of it. Also if you find any bugs let me know. I’m pretty sure that a 2.0 will be necessary!
