How to Use This Calculator

Using this auto loan calculator is simple:

The calculator uses standard auto loan formulas to provide accurate estimates. Remember that actual loan terms may vary based on your creditworthiness and the specific loan program you qualify for.

Formula Used

The calculator uses the standard auto loan payment formula:

Monthly Payment Formula

M = P [ i(1 + i)n ] / [ (1 + i)n - 1 ]

Where:

  • M = monthly payment
  • P = principal loan amount
  • i = monthly interest rate (annual rate divided by 12)
  • n = number of payments (loan term in years × 12)

Total interest is calculated by subtracting the original loan amount from the sum of all monthly payments.

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% annual interest rate over 5 years:

  1. Monthly interest rate = 4.5% ÷ 12 = 0.375% or 0.00375
  2. Number of payments = 5 × 12 = 60
  3. Using the formula: M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ]
  4. This calculates to approximately $472.50 per month
  5. Total payments = $472.50 × 60 = $28,350
  6. Total interest = $28,350 - $25,000 = $3,350

This example shows you'll pay about $472.50 per month with $3,350 in total interest over the life of the loan.
