Formula Used

The auto loan payment calculator uses the standard amortization formula to calculate your monthly payments:

Amortization 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 required to fully amortize the loan over the specified term.

Worked Example

Let's calculate the monthly payment for a $25,000 auto loan with a 5% annual interest rate over 5 years.

Example Calculation

Principal (P) = $25,000

Annual Interest Rate = 5% (0.05)

Monthly Interest Rate (r) = 0.05 / 12 ≈ 0.004167

Loan Term in Months (n) = 5 × 12 = 60

Monthly Payment = $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Monthly Payment ≈ $464.69

For this example, the monthly payment would be approximately $464.69, with a total interest paid of $1,949.40 over the life of the loan.
