Formula Used

The auto payment calculator uses the standard mortgage payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount (loan amount - down payment)
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.

Worked Example

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

Principal (P) = $25,000
Annual interest rate = 5% or 0.05
Monthly interest rate (r) = 0.05 / 12 ≈ 0.004167
Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $25,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)

Monthly Payment ≈ $453.24

So, the estimated monthly payment would be $453.24.
