Formula Used
The calculation uses the standard auto loan payment formula:
Auto 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 divided by 12)
- n = Number of payments (loan term in years × 12)
This formula calculates the fixed monthly payment required to pay off the loan in the specified term.
Worked Example
Let's calculate a PenFed auto loan with these parameters:
- Loan amount: $25,000
- Annual interest rate: 4.5%
- Loan term: 5 years
Using the formula:
Calculation Steps
1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375
2. Calculate number of payments: 5 × 12 = 60
3. Plug values into formula:
Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
4. Calculate the result: $452.34 per month
Over 5 years, you would pay a total of $27,140.40, with $2,140.40 going toward interest.

How does the interest rate affect my monthly payment?
A higher interest rate will increase your monthly payment because more of each payment goes toward interest. Conversely, a lower rate will reduce your monthly payment.
Can I pay extra toward my loan?
