What is Auto Loan Refinancing?

Auto loan refinancing is the process of replacing your current auto loan with a new one, typically with better terms. This can lead to lower monthly payments, reduced interest rates, or a shorter loan term. The goal is to save money over the life of the loan.

How to Use the Cost per Auto Loan Refinancing Calculator?

To use the calculator, you need to input the following details:

  1. Current Loan Amount: The total amount you owe on your existing auto loan.
  2. Current Interest Rate: The annual interest rate of your current loan.
  3. New Interest Rate: The annual interest rate of the new loan you are considering.
  4. New Loan Term: The duration of the new loan in months.

Once you have entered these values, click the “Calculate” button to see your results.

How to Calculate Monthly Payments and Savings?

The monthly payment for an auto loan can be calculated using the formula:

Monthly Payment (PMT):

§§ PMT = \frac{P \times r}{1 - (1 + r)^{-n}} §§

where:

  • § PMT § — monthly payment
  • § P § — principal amount (loan amount)
  • § r § — monthly interest rate (annual interest rate divided by 12)
  • § n § — total number of payments (loan term in months)

Total Savings can be calculated by comparing the total payments of the current loan and the new loan:

§§ \text{Total Savings} = (\text{Current Monthly Payment} \times \text{Current Loan Term}) - (\text{New Monthly Payment} \times \text{New Loan Term}) §§

Example Calculation

Current Loan Details:

  • Current Loan Amount (§ P §): $20,000
  • Current Interest Rate (§ r §): 5%
  • New Interest Rate (§ r’ §): 3%
  • New Loan Term (§ n’ §): 60 months

  1. Calculate the current monthly payment:

    • Current Monthly Payment = §§ \frac{20000 \times \frac{0.05}{12}}{1 - (1 + \frac{0.05}{12})^{-60}} = 377.42 §§

  2. Calculate the new monthly payment:

    • New Monthly Payment = §§ \frac{20000 \times \frac{0.03}{12}}{1 - (1 + \frac{0.03}{12})^{-60}} = 359.37 §§

  3. Calculate total savings:

    • Total Savings = §§ (377.42 \times 60) - (359.37 \times 60) = 108.30 §§

When to Use the Cost per Auto Loan Refinancing Calculator?

  1. Assessing Loan Options: Determine if refinancing your auto loan is beneficial based on current market rates.
  2. Budgeting: Understand how refinancing can impact your monthly budget and overall financial health.
  3. Financial Planning: Evaluate long-term savings and costs associated with different loan terms and interest rates.

Key Terms Defined

  • Principal Amount (P): The original sum of money borrowed in a loan.
  • Interest Rate (r): The percentage of the principal charged as interest over a specific period.
  • Loan Term (n): The duration over which the loan must be repaid, typically expressed in months.
  • Monthly Payment (PMT): The amount paid each month towards the loan, including both principal and interest.

Practical Examples

  • Refinancing for Lower Payments: A borrower may refinance to take advantage of lower interest rates, resulting in reduced monthly payments.
  • Shortening Loan Terms: Some may choose to refinance to a shorter loan term, which can save on interest costs over the life of the loan, even if the monthly payment is higher.
