About this calculator
Compare the total interest paid on your current auto loan versus a new refinance offer, including amortization over the remaining term.
Frequently Asked Questions
Does this include fees?
Yes, any refinance fees you enter are added to the total cost of the new loan before comparing.
What if the new term is shorter or longer?
The calculator amortizes each loan independently over its own remaining term, so you can compare different term lengths directly.
Is this the same as APR comparison?
No — this compares actual total dollars of interest paid, which accounts for both rate and remaining term, giving a more complete picture than APR alone.
