Auto Loan Calculation Formula

The auto loan calculator uses the standard loan payment formula:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ] Where: M = Monthly payment P = Principal loan amount (Loan amount - Down payment) i = Monthly interest rate (Annual rate / 12 / 100) n = Number of payments (Loan term in years × 12)

This formula calculates the fixed monthly payment for a loan with a fixed interest rate.

Worked Example

Let's calculate a loan for a $25,000 vehicle with these terms:

Loan amount: $25,000
Down payment: $5,000
Loan term: 5 years
Annual interest rate: 4.5%

The principal loan amount is $20,000 ($25,000 - $5,000 down payment).

Monthly interest rate = 4.5% / 12 / 100 = 0.00375

Number of payments = 5 × 12 = 60

Using the formula:

M = 20000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] M ≈ $362.50

Total interest paid = ($362.50 × 60) - $20,000 = $735

Total loan cost = $25,000 + $735 = $25,735

Frequently Asked Questions

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total cost of credit, including fees and interest, while the interest rate is just the interest portion. APR is always higher than the interest rate.

How does a down payment affect my loan?

A larger down payment reduces your loan amount and monthly payments, but it also means you pay more upfront. It can also improve your credit score and qualify you for better loan terms.

What happens if I miss a payment?

Missing payments can result in late fees, higher interest charges, and potential damage to your credit score. It's important to make payments on time to avoid these consequences.
