Formula Used

The car installment calculator uses the standard loan payment 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 Interest Rate / 12 / 100)
n = Number of payments (Loan Term × 12)

This formula calculates the fixed monthly payment required to pay off the loan over the specified term.

Worked Example

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

Principal loan amount = $30,000 - $3,000 = $27,000
Monthly interest rate = 5% / 12 / 100 = 0.004167
Number of payments = 5 × 12 = 60
Monthly Payment = $27,000 × (0.004167(1 + 0.004167)^60) / ((1 + 0.004167)^60 - 1)
Monthly Payment ≈ $475.60

Using this calculator, you would enter these values and get the same result.

Comparison Table

Here's a comparison of different loan terms for the same car purchase:

Loan Term	Interest Rate	Monthly Payment	Total Interest Paid
3 years	5%	$825.32	$2,163.96
4 years	5%	$660.28	$1,681.48
5 years	5%	$475.60	$1,087.20
6 years	5%	$375.20	$729.60

This table shows how longer loan terms result in lower monthly payments but higher total interest paid.
