PenFed Auto Loan Formula

The auto loan payment is calculated using the standard loan 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)

This formula accounts for the interest on the loan balance each month, which is why the monthly payment decreases over time as the principal balance is paid down.

Example Calculation

Let's calculate a $25,000 auto loan with a 4.5% annual interest rate over 5 years (60 months):

Monthly payment = $25,000 [ (0.045/12)(1 + 0.045/12)^60 ] / [ (1 + 0.045/12)^60 - 1 ]

Monthly payment = $25,000 [ 0.00375 × 1.00375^60 ] / [ 1.00375^60 - 1 ]

Monthly payment = $25,000 [ 0.00375 × 1.2607 ] / [ 0.2607 ]

Monthly payment = $25,000 [ 0.00465 ] / 0.2607

Monthly payment = $25,000 × 0.01784 = $446.00

In this example, your monthly payment would be $446.00, with a total interest of $3,120.00 and a total loan cost of $28,120.00.
