Formula Used

The calculator uses the standard auto loan payment formula:

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

Where:

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

California-specific adjustments include:

State sales tax (7.25%) added to the loan amount
Documentation fee (1-2% of loan amount)
Title fee ($25-$50)
Other fees as applicable

Worked Example

Let's calculate a loan for a $30,000 vehicle with these terms:

Loan amount: $30,000
Down payment: $3,000
Loan term: 5 years
Interest rate: 4.5%

After applying California's 7.25% sales tax, the total loan amount becomes $32,250. After the $3,000 down payment, the principal is $29,250.

The monthly payment calculation:

Monthly rate = 4.5% ÷ 12 = 0.00375

Number of payments = 5 × 12 = 60

Monthly payment = $29,250 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Monthly payment = $523.78

Total interest paid over 5 years: $3,766.80

Total amount paid: $33,016.80
