Formula Used
The auto loan payment is calculated using the following 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 the interest on the loan balance over the entire term, providing an accurate estimate of your monthly payments.
Worked Example
Let's calculate the monthly payment for a $25,000 auto loan with a 4.5% annual interest rate over 5 years:
- Principal (P) = $25,000
- Annual interest rate = 4.5% or 0.045
- Monthly interest rate (r) = 0.045 / 12 ≈ 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 ≈ $472.87
This means you would pay approximately $472.87 per month for 60 months, with a total interest of about $3,462.20.
Frequently Asked Questions
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) is the total cost of credit, including fees, while the interest rate is the actual percentage charged on the loan balance. APR is always higher than the interest rate.
How does a longer loan term affect my payments?
A longer loan term means lower monthly payments but more total interest paid over the life of the loan. A shorter term results in higher monthly payments but less total interest.
Can I pay extra toward my loan?
Yes, paying extra toward your loan can reduce the principal balance faster and lower your total interest. You can use the calculator to see how different extra payments affect your loan.
