Auto Finance Calculator Ontario

This auto finance calculator helps you determine your monthly payments, total interest, and affordability for car loans in Ontario. Whether you're buying a new or used vehicle, this tool provides clear insights into your financing options.

How to Use This Calculator

To use the auto finance calculator for Ontario:

Enter the loan amount (price of the vehicle)
Select the loan term in years
Input your interest rate (annual percentage rate)
Choose between fixed or variable interest rate
Click Calculate to see your monthly payment and total interest

The calculator will display your estimated monthly payment, total interest paid over the loan term, and the total amount paid (principal + interest).

Formula Used

The auto finance calculator uses the standard loan payment formula:

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

Where:

P = Principal loan amount (vehicle price)
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

For variable rate loans, the calculator uses the average interest rate over the loan term.

Worked Example

Let's calculate a loan for a $30,000 vehicle with a 5-year term at a 4.5% annual interest rate:

Monthly interest rate = 4.5% ÷ 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = $30,000 × (0.00375(1+0.00375)^60) / ((1+0.00375)^60 - 1) ≈ $558.36
Total interest = ($558.36 × 60) - $30,000 ≈ $3,502.20

Using the calculator with these values would show a monthly payment of $558.36 and total interest of $3,502.20.
