Formula Used

The car payment calculation uses the standard loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)
Where:
P = Principal loan amount (vehicle price - down payment)
r = Monthly interest rate (annual rate / 12)
n = Number of payments (loan term in years × 12)

Ontario sales tax is calculated at 13% of the vehicle price and added to the total amount financed.

Worked Example

Let's calculate a car payment for a $30,000 vehicle with a 10% down payment, 5-year loan term, and 4% annual interest rate.

Vehicle price: $30,000
Down payment: 10% of $30,000 = $3,000
Principal loan amount: $30,000 - $3,000 = $27,000
Monthly interest rate: 4% ÷ 12 = 0.333%
Number of payments: 5 × 12 = 60
Monthly payment: $27,000 × (0.00333(1 + 0.00333)^60) / ((1 + 0.00333)^60 - 1) ≈ $478.50

Total interest paid: $478.50 × 60 - $27,000 ≈ $1,670

Total amount financed: $27,000 + $1,670 = $28,670

Ontario Sales Tax
