Formula Used

The Ally Auto Payment is calculated using the standard loan payment formula:

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

Where:

P = Principal loan amount
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Number of payments (Loan term in years × 12)

This formula accounts for both the principal amount and the interest charged over the life of the loan.

Worked Example

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

Principal (P) = $25,000
Annual interest rate = 4.5%
Monthly interest rate (r) = 4.5% ÷ 12 ÷ 100 = 0.00375
Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Monthly Payment ≈ $462.50

Your estimated monthly payment would be $462.50, with a total interest paid of $3,750 over the life of the loan.
