Why does the interest fluctuate on a fixed-rate car loan?

Answered by Car Loans Expert Johnny on March 18, 2021

I have a car loan with a fixed rate, but the amount of interest charged varies month to month. Why does the interest amount fluctuate like this?

Interest is applied on the total principal owed on the loan. This amount changes as the loan goes on, so what you should see is a larger amount of your monthly payment going towards the principal and a smaller amount going towards the interest. Furthermore, some months have more days than others and that can affect the amount of interest paid, too.

This app is great, but the customer service is even better! Not to mention convenient! My husband and I got the lowest rate (much lower than the rates I was finding online through my own searches), quickly, and pretty much all through text message! Thank you so much for a hassle free experience👍
