Formula Explained
The auto car payment calculator uses the standard loan payment formula:
Loan Payment Formula
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 years multiplied by 12)
This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.
Worked Examples
Example 1: $25,000 Loan at 4.5% APR for 5 Years
Monthly Payment: $477.56
Total Interest Paid: $3,442.40
This example shows a moderate loan with a reasonable interest rate and term.
Example 2: $40,000 Loan at 3.9% APR for 7 Years
Monthly Payment: $602.45
Total Interest Paid: $5,542.70
This example demonstrates how a longer loan term can result in higher total interest payments.
Frequently Asked Questions
What is the difference between APR and interest rate?
The Annual Percentage Rate (APR) is the total cost of credit, including any fees, while the interest rate is the actual percentage charged on the loan principal. APR is always higher than the interest rate.
How does loan term affect my monthly payment?
A longer loan term means lower monthly payments but higher total interest paid over the life of the loan. A shorter term results in higher monthly payments but lower total interest.
What factors can affect my car payment?
Several factors can affect your car payment, including the loan amount, interest rate, loan term, down payment, and any additional fees or taxes.
