Formula Used
The auto loan calculator uses the standard loan payment formula:
Monthly Payment (PMT) = [Loan Amount × (Interest Rate/12) × (1 + Interest Rate/12)^Term] ÷ [(1 + Interest Rate/12)^Term - 1]
Where:
- Loan Amount = Kelley Blue Book Value - Down Payment
- Interest Rate = Annual interest rate (as a decimal)
- Term = Loan term in months
Total Interest = (Monthly Payment × Term) - Loan Amount
Total Cost = Loan Amount + Total Interest
Worked Example
Let's calculate a loan for a vehicle with a Kelley Blue Book value of $25,000, a $5,000 down payment, 4.5% annual interest rate, and a 60-month (5-year) loan term.
- Loan Amount = $25,000 - $5,000 = $20,000
- Monthly Interest Rate = 4.5% ÷ 12 = 0.375% or 0.00375
- Monthly Payment = [$20,000 × 0.00375 × (1 + 0.00375)^60] ÷ [(1 + 0.00375)^60 - 1]
- Monthly Payment ≈ $362.50
- Total Interest = ($362.50 × 60) - $20,000 = $7,500
- Total Cost = $20,000 + $7,500 = $27,500
Using our calculator with these values will give you the same results.
