Formulas Used

The auto calculator uses the following formulas to provide accurate estimates:

Monthly Payment

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

Where:

P = Loan amount (Purchase Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12)
n = Number of payments (Loan Term * 12)

Total Cost of Ownership

Total Cost = (Monthly Payment * 12 * Loan Term) + (Annual Maintenance * Loan Term) + (Annual Fuel Cost * Loan Term)

Annual Fuel Cost = (Annual Mileage / MPG) * Cost of Gas * 12
