Formula Used

The calculator uses the standard auto loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount i = Monthly interest rate (annual rate divided by 12) n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate.

Worked Example

Let's calculate a $25,000 loan with a 4.5% annual interest rate over 5 years:

Principal (P) = $25,000
Annual interest rate = 4.5% or 0.045
Monthly interest rate (i) = 0.045 / 12 = 0.00375
Number of payments (n) = 5 × 12 = 60
Plugging into the formula:
M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] M ≈ $472.87
Total interest paid = (Monthly payment × 60) - Principal = ($472.87 × 60) - $25,000 = $1,224.20

This example shows that a $25,000 loan at 4.5% over 5 years would have a monthly payment of approximately $472.87 with $1,224.20 in total interest.

Frequently Asked Questions

What is the difference between APR and interest rate?

The interest rate is the cost of borrowing, while the APR (Annual Percentage Rate) includes all fees and costs associated with the loan. Navy Federal's APR will typically be higher than the stated interest rate.

Can I get a lower interest rate with Navy Federal?

Navy Federal offers competitive rates, but your actual rate may vary based on your credit score, loan amount, and other factors. Members with excellent credit may qualify for lower rates.

How does down payment affect my loan?

A larger down payment reduces your loan amount and can lower your monthly payments and total interest. Navy Federal typically requires a minimum down payment of 3.5% for conventional loans.

What fees are associated with a Navy Federal auto loan?

Common fees include origination fees (typically 1% of the loan amount), appraisal fees, and title fees. These fees are included in the APR calculation.
