Formula Used

The calculator uses the standard auto 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 (APR/12/100) n = Number of payments (Loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off a loan with compound interest.

Worked Example

Let's calculate an example auto loan payment:

Loan amount: $25,000
Loan term: 5 years
Annual interest rate: 4.5%

Using the formula:

i = 4.5%/12/100 = 0.00375 n = 5 × 12 = 60 M = 25000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ] M ≈ $452.34

For this example, the estimated monthly payment would be $452.34.
