Formula Used

The calculator uses the standard auto loan payment formula:

Auto 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)

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

Worked Example

Let's calculate a loan with these terms:

  • Loan Amount: $25,000
  • Loan Term: 5 years
  • Annual Interest Rate: 4.5%

Using the formula:

Calculation Steps

1. Convert annual rate to monthly: 4.5% ÷ 12 = 0.375% or 0.00375

2. Calculate number of payments: 5 × 12 = 60

3. Plug values into formula: $25,000 × [0.00375(1 + 0.00375)^60] / [(1 + 0.00375)^60 - 1]

4. Calculate monthly payment: $25,000 × [0.00375 × 1.00375^60] / [1.00375^60 - 1] ≈ $452.34

Total interest paid over 5 years: $452.34 × 60 - $25,000 = $1,120.20

Interpreting Results

When you use the Landmark Auto Loan Calculator, you'll see several key results:

  • Monthly Payment: The fixed amount you'll pay each month.
  • Total Interest: The total amount of interest you'll pay over the life of the loan.
  • Total Amount Paid: The sum of the principal and total interest.

The chart visualization helps you see how much of each payment goes toward principal versus interest over time.
