Use this Navy Federal Credit Union Auto Loan Calculator to estimate your monthly payments, total interest, and loan cost before applying for a car loan. The calculator uses current Navy Federal rates and terms to provide an accurate estimate.
How to Use This Calculator
To get an estimate of your auto loan payments:
- Enter the loan amount you're requesting
- Select your loan term (36-84 months)
- Choose your interest rate (current Navy Federal rates apply)
- Click "Calculate" to see your estimated monthly payment
The calculator will display your estimated monthly payment, total interest paid, and total cost of the loan. You can also view a breakdown of how your payments are allocated between principal and interest.
Formula Used
The auto loan payment is calculated using the standard loan payment formula:
Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Number of payments (loan term in months)
Total interest paid is calculated by subtracting the loan amount from the total of all monthly payments.
Worked Example
Let's calculate a $25,000 loan with a 4.5% annual interest rate over 60 months (5 years):
- Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
- Number of payments = 60
- Monthly payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $460.42
- Total payments = $460.42 × 60 ≈ $27,625.20
- Total interest = $27,625.20 - $25,000 ≈ $2,625.20
This example shows you would pay approximately $460.42 per month with a total interest cost of about $2,625.20.
