Formula Used

The auto loan calculator uses 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 (APR/12)
  • n = Number of payments (Loan term × 12)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term.

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 Payment = $25,000 × (0.05/12 × (1 + 0.05/12)^60) / ((1 + 0.05/12)^60 - 1)

Calculating this gives you a monthly payment of approximately $465.24.

Over the 5-year term, you would pay a total of $27,914.40, with $2,914.40 going to interest.
