Formula Used
The monthly payment for an auto loan 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 × 12)
This formula accounts for the interest charged on the outstanding loan balance each month, providing an accurate estimate of your monthly payment.
Worked Example
Let's calculate the monthly payment for a $20,000 loan with a 5-year term and 4.5% annual interest rate.
- Convert the annual interest rate to a monthly rate: 4.5% / 12 = 0.375% or 0.00375 in decimal.
- Calculate the number of payments: 5 years × 12 = 60 payments.
- Apply the loan payment formula:
Monthly Payment = $20,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
= $20,000 × (0.00375 × 1.00375^60) / (1.00375^60 - 1)
= $20,000 × (0.00375 × 1.247) / (1.247 - 1)
= $20,000 × 0.004605 / 0.247
= $20,000 × 0.01868 ≈ $373.60
Your monthly payment would be approximately $373.60, with a total interest of $1,736.00 over the life of the loan.
