Calculer Pret Auto

Calculating your auto loan is essential for understanding your monthly payments, total interest, and repayment schedule. This calculator helps you estimate these figures based on your loan amount, interest rate, and term.

How to Use This Calculator

To calculate your auto loan:

Enter the loan amount you're requesting
Input the annual interest rate (APR)
Select the loan term in years
Click "Calculate" to see your results

The calculator will display your monthly payment, total interest paid over the life of the loan, and an amortization schedule showing how your payments break down.

Formula Used

The monthly payment for an auto loan 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 divided by 12)
n = Number of payments (loan term in years × 12)

Total interest is calculated by subtracting the principal from the total amount paid over the life of the loan.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $25,000
Annual interest rate: 5%
Loan term: 5 years

Using the formula:

Monthly rate = 5% ÷ 12 = 0.0041667

Number of payments = 5 × 12 = 60

Monthly payment = $25,000 × (0.0041667(1 + 0.0041667)^60) / ((1 + 0.0041667)^60 - 1)

Monthly payment ≈ $456.25

Total interest = ($456.25 × 60) - $25,000 = $1,175

This means you would pay approximately $456.25 per month with a total interest cost of $1,175 over the life of the loan.

Frequently Asked Questions

What is the difference between APR and interest rate?: The annual percentage rate (APR) is the total cost of credit, including all fees and interest, while the interest rate is just the interest portion of the APR.
How does loan term affect my monthly payment?: A longer loan term means lower monthly payments but more total interest paid. A shorter term results in higher monthly payments but less total interest.
What is the amortization schedule?: The amortization schedule shows how each payment is applied to principal and interest over the life of the loan, with a breakdown of each payment's components.
Can I pay extra toward my loan?: Yes, paying extra principal can reduce your total interest and pay off your loan faster. The calculator can show you the impact of additional payments.
