Formula Used

The calculator uses the standard auto loan payment formula:

Monthly Payment Formula

M = P [i(1 + i)^n] / [(1 + i)^n - 1]

Where:

M = Monthly payment
P = Principal loan amount ($45,000)
i = Monthly interest rate (annual rate / 12 / 100)
n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the specified term.

Worked Example

Let's calculate a $45,000 loan with a 5.5% annual interest rate over 5 years:

Principal (P) = $45,000
Annual interest rate = 5.5%
Monthly interest rate (i) = 5.5% / 12 ≈ 0.4583%
Number of payments (n) = 5 years × 12 = 60 months

Plugging these values into the formula:

Calculation Steps

M = 45000 [0.004583(1 + 0.004583)^60] / [(1 + 0.004583)^60 - 1]

M ≈ $846.32 per month

This example shows that with a $45,000 loan at 5.5% interest over 5 years, your monthly payment would be approximately $846.32.

Interpreting Results

When you run the calculation, you'll see several key results:

Monthly Payment: The fixed amount you'll pay each month
Total Interest: The total amount of interest you'll pay over the life of the loan
Total Cost: The sum of your principal and total interest

Use this information to compare different loan options, understand your financial commitment, and make informed decisions about your auto purchase.
