Formula Used
Auto Loan Payment Formula
The monthly payment (P) for an auto loan is calculated using the formula:
P = (A × r × (1 + r)^n) / ((1 + r)^n - 1)
Where:
- A = Loan amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest on the remaining balance each month, providing an accurate estimate of your monthly payments.
Worked Example
Let's calculate a $25,000 loan at 4.5% annual interest for 5 years:
- Monthly interest rate = 4.5% ÷ 12 ÷ 100 = 0.00375
- Number of payments = 5 × 12 = 60
- Monthly payment = (25000 × 0.00375 × (1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $452.34
- Total interest = (Monthly payment × 60) - Loan amount = $1,352.20
This example shows that your total cost would be $26,352.20, with $1,352.20 paid in interest.
