Formula Explained

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 multiplied by 12)

This formula accounts for the interest on the loan balance each month, which is why the monthly payment remains constant throughout the loan 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:

i = 5%/12 = 0.0041667 n = 5*12 = 60 M = 25000 [ 0.0041667(1 + 0.0041667)^60 ] / [ (1 + 0.0041667)^60 - 1 ] M ≈ $472.82

Over 5 years, you would pay $2,836.80 in interest and a total of $27,836.80.
