Formula Used

The monthly payment is calculated using the standard mortgage formula:

Monthly Payment = P * (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount (Car Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12 / 100)
n = Number of payments (Loan Term in Years * 12)

This formula accounts for the interest you'll pay over the life of the loan and provides an accurate estimate of your monthly obligation.

Worked Example

Let's calculate a monthly payment for a $30,000 car with a $3,000 down payment, 5% interest rate, and 5-year loan term.

Principal (P) = $30,000 - $3,000 = $27,000
Monthly interest rate (r) = 5% / 12 / 100 = 0.004167
Number of payments (n) = 5 * 12 = 60
Plugging into the formula: $27,000 * (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
This calculation results in a monthly payment of approximately $475.50

Using this example, you can see how the calculator works and verify its accuracy with your own numbers.

Frequently Asked Questions

What is the difference between APR and interest rate?

The Annual Percentage Rate (APR) is the total cost of credit, including fees and interest, while the interest rate is just the interest portion. APR is typically higher than the interest rate.

How does a longer loan term affect my monthly 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.

What is the difference between a secured and unsecured car loan?

A secured car loan uses the car itself as collateral, offering better terms. An unsecured loan doesn't use the car as collateral and typically has higher interest rates.
