Formula Used

The calculator uses the following formula to calculate your monthly loan payment:

Monthly Payment Formula

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

P = Monthly payment
PV = Principal loan amount (Car price - Down payment)
r = Monthly interest rate (Annual interest rate ÷ 12)
n = Number of payments (Loan term in years × 12)

The total cost of ownership is calculated by adding the total interest paid to the principal loan amount and any additional expenses.

Worked Example

Let's say you want to buy a car priced at $25,000 with a $5,000 down payment. You take out a 5-year loan at an annual interest rate of 4%. You also estimate additional expenses of $2,000 (insurance, taxes, and fees).

Using the calculator:

Car price: $25,000
Down payment: $5,000
Loan term: 5 years
Annual interest rate: 4%
Additional expenses: $2,000

The calculator will show:

Monthly payment: $382.50
Total interest paid: $2,500
Total cost of ownership: $29,500

This means you'll pay $382.50 per month for 5 years, totaling $23,550 in principal and interest payments. Adding the $2,000 in additional expenses gives you a total cost of ownership of $29,500.
