What Is a Car Loan?
A car loan is a financial agreement where a lender provides funds to purchase a vehicle, and the borrower repays it over time, usually with interest. Car loans make it possible for buyers to afford a car without paying the full amount upfront. However, understanding your monthly payments and total repayment is critical to avoid overextending your finances.
How the PenFed Car Loan Calculator Works
The calculator uses a standard auto loan formula:Monthly Payment=1−(1+r)−nPrincipal×r
Where:
- Principal = Car price – Down payment
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (loan term × 12)
This formula accounts for compounding interest, providing an accurate monthly payment and total loan amount over the loan term.
How To Use the Car Loan Calculator
Step 1: Enter the Car Price
Input the full cost of the car. This can be the dealer price or a negotiated amount.
Example: $25,000
Step 2: Enter Down Payment
Specify the amount you plan to pay upfront. A higher down payment reduces the loan principal, which lowers your monthly payment.
Example: $5,000
Step 3: Enter Interest Rate
Enter the annual interest rate offered by the lender. Lower rates reduce monthly payments and overall loan costs.
Example: 4.5%
Step 4: Enter Loan Term (Years)
Specify the number of years over which you want to repay the loan. Shorter terms have higher monthly payments but lower total interest costs.
Example: 5 years
Step 5: Click “Calculate”
The calculator instantly provides:
- Monthly Payment – What you pay each month
- Total Payment – Total cost of the loan over its term
Step 6: Reset for New Calculations
Click Reset to clear inputs and calculate a new scenario.
Example Calculation
Let’s say you want to buy a car with these parameters:
- Car Price: $30,000
- Down Payment: $5,000
- Interest Rate: 5%
- Loan Term: 5 years
Calculation steps:
- Principal = 30,000 – 5,000 = $25,000
- Monthly Interest Rate = 5 ÷ 12 ÷ 100 = 0.004167
- Number of Payments = 5 × 12 = 60 months
- Monthly Payment = 25,000 × 0.004167 ÷ (1 – (1 + 0.004167)^-60) ≈ $471.78
- Total Payment = 471.78 × 60 ≈ $28,306.80
This shows you how much you will pay monthly and over the life of the loan.
