Formula Explained
The auto loan car payment is calculated using the standard loan payment formula:
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 divided by 12)
- 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, providing an accurate estimate of your monthly obligation.
Worked Example
Let's calculate a monthly payment for a $25,000 loan with a 4.5% annual interest rate over 5 years.
- Convert the annual interest rate to a monthly rate: 4.5% ÷ 12 = 0.375% or 0.00375 in decimal form.
- Calculate the number of payments: 5 years × 12 = 60 months.
- Plug the values into the formula:
Monthly Payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)
- The calculation yields a monthly payment of approximately $477.38.
This example shows how the calculator can help you estimate your monthly payments before applying for a loan.
