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 (Purchase Price - Down Payment + TTL)
r = Monthly interest rate (Annual Rate / 12)
n = Number of payments (Loan Term × 12)

Total Interest = (Monthly Payment × n) - Principal

Total Amount Financed = Monthly Payment × n

Worked Example

Let's calculate a loan for a $30,000 vehicle with a $3,000 down payment, 4.5% interest rate, 5-year term, and $2,000 TTL.

Principal = $30,000 - $3,000 + $2,000 = $29,000
Monthly rate = 4.5% / 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = $29,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $525.45
Total interest = ($525.45 × 60) - $29,000 ≈ $1,526.20
Total amount financed = $525.45 × 60 ≈ $31,526.20
