Car Loan Amortization Calculator








A car loan amortization calculator helps you understand the monthly payment, total repayment, and interest paid for your car loan. By providing the loan amount, interest rate, and loan term, you can plan your finances effectively and avoid surprises.

Car Loan Amortization Formula

The formula to calculate the monthly payment for a car loan is:


Monthly Payment = P × r × ( 1 + r ) n ( 1 + r ) n 1

Where:

  • P: Loan Amount
  • r: Monthly interest rate (annual rate / 12)
  • n: Total number of payments (loan term in years × 12)

Real-Life Example

Let’s say you take a car loan with the following terms:

  • Loan Amount (P): $20,000
  • Annual Interest Rate: 6%
  • Loan Term: 5 years

Step 1: Convert the annual interest rate to a monthly rate:
Monthly Interest Rate (r) = 6% / 12 = 0.005

Step 2: Calculate the total number of payments:
n = 5 years × 12 = 60 payments

Step 3: Apply the formula:

Monthly Payment = (20000 × 0.005 × (1 + 0.005)^60) / ((1 + 0.005)^60 – 1) ≈ $386.66

In this example, the monthly payment would be $386.66.

Benchmark Indicators

Understanding typical car loan terms can help you evaluate your options:

Low Rate: 2% – 5% – Common for excellent credit

Average Rate: 6% – 10% – Standard for most borrowers

High Rate: Above 10% – Typical for subprime credit or short loans

Short Loan Term: Less than 36 months – Higher monthly payments

Long Loan Term: 48-72 months – Lower monthly payments, but higher total interest

Frequently Asked Questions

What is car loan amortization?

Car loan amortization refers to the process of spreading loan payments over a fixed term, where each payment includes a portion of the principal and interest.

How do interest rates affect monthly payments?

Higher interest rates increase your monthly payment, while lower rates reduce it. The term length also plays a crucial role in determining payment size.

Can I pay off my car loan early?

Many lenders allow early repayments, but some may charge prepayment penalties. Check your loan terms for details.

What is the ideal loan term for a car?

The ideal loan term depends on your budget. Shorter terms have higher payments but less interest, while longer terms have lower payments but more interest.

What happens if I miss a payment?

Missing a payment can lead to late fees, credit score impact, or repossession. Contact your lender immediately to discuss options if you’re unable to pay.
