Formula Used

Monthly Payment Formula

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

PMT = P × [r(1 + r)^n] / [(1 + r)^n - 1]

Where:

P = Principal loan amount ($31,000)
r = Monthly interest rate (APR/12/100)
n = Number of payments (Term × 12)

This formula accounts for the interest you'll pay over the life of the loan. The calculator also calculates the total interest paid and the total amount paid over the loan term.

Worked Example

Let's calculate a $31,000 loan with a 5% annual interest rate and a 5-year term:

Monthly interest rate = 5%/12 = 0.4167%
Number of payments = 5 × 12 = 60
Using the formula: PMT = 31000 × [0.004167(1.004167)^60] / [(1.004167)^60 - 1]
This calculates to approximately $592.45 per month

Over 5 years, you would pay a total of $35,547.20, with $4,547.20 going to interest.

Interpreting Results

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

Monthly Payment: Your regular payment amount
Total Interest: The total amount of interest you'll pay over the loan term
Total Amount Paid: The sum of your principal and interest payments

Use these numbers to compare different loan options and understand your financial commitment. The chart visualization helps you see how your loan balance decreases over time.

Important Note

These calculations are estimates based on the information you provide. Actual payments may vary slightly due to rounding and other factors. Always check with your lender for precise terms.

FAQ

What is an auto loan?

An auto loan is a type of secured loan used to purchase a vehicle. The vehicle serves as collateral for the loan.

How does the interest rate affect my payments?

A higher interest rate means you'll pay more in interest over the life of the loan, increasing your total payments. Lower rates reduce your interest costs.

Can I pay off my loan early?

Yes, you can pay off your loan early without penalty, but you'll save more on interest if you make extra payments toward the principal rather than just paying the minimum.
