Formula Used

Monthly Payment Formula

The monthly payment (P) is calculated using the formula:

P = (A × r × (1 + r)^n) / ((1 + r)^n - 1)

Where:

A = 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 life of the loan, providing an accurate monthly payment amount.

Worked Example

Let's calculate a monthly payment for a $25,000 loan with a 4.5% annual interest rate over 5 years:

Loan amount (A) = $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:

P = ($25,000 × 0.00375 × (1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Calculating this gives a monthly payment of approximately $454.23.

Total interest paid over the loan term would be $2,725.80, and the loan would be paid off in December 2028.

Interpreting Results

The calculator provides three key results:

Monthly Payment: The amount you'll pay each month.
Total Interest: The total amount of interest you'll pay over the life of the loan.
Loan Payoff Date: The date when your loan will be fully paid off.

These results help you understand the true cost of your auto loan and plan your budget accordingly. Comparing different loan terms and interest rates can help you find the most affordable financing option.
