Understanding Auto Loan Calculations
The auto loan calculator uses a standard amortization formula to determine the monthly payment.
Amortization Formula
The formula considers the principal loan amount, interest rate, and loan term to arrive at the monthly payment.
- 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 months)
