Formula Used

The car payment calculation uses the standard loan payment formula:

Monthly Payment Formula

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

Where:

  • M = Monthly payment
  • P = Loan principal (amount)
  • i = Monthly interest rate (annual rate divided by 12)
  • n = Number of payments (loan term in years multiplied by 12)

This formula accounts for the interest on the loan and provides an accurate estimate of your monthly payments.

Worked Example

Let's calculate the monthly payment for a $25,000 car loan with a 4.5% annual interest rate over 5 years.

Example Calculation

Loan amount: $25,000

Annual interest rate: 4.5%

Loan term: 5 years

Monthly interest rate: 4.5% ÷ 12 = 0.375% or 0.00375

Number of payments: 5 × 12 = 60

Using the formula: M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]

Calculated monthly payment: $478.89

This example shows that with these loan terms, your monthly payment would be approximately $478.89.
