Your Summary
Explanation
About Vehicle Loan Total Cost Calculator
Financing a vehicle means paying back more than the sticker price once interest is added. This calculator takes the amount you borrow, the annual interest rate, and the term in months, then applies the standard amortization formula to show what the loan costs in total.
You get the monthly payment, the total interest across the whole term, and the combined total cost, with a chart splitting principal from interest.
Formula & Mathematical Calculation
pmt = r === 0 ? (p ÷ n) : (p × r × pow(1 + r, n)) ÷ (pow(1 + r, n) - 1)
tot = pmt × n
Derived directly from the verified calculation function in the tool engine.
Calculation Example
Suppose you finance $28,000 at an annual rate of 6.5% over a 60-month term.
- Monthly rate r = 6.5 ÷ 100 ÷ 12 = 0.00541667, and (1 + r)60 = 1.382817.
- Monthly Payment = 28,000 × 0.00541667 × 1.382817 ÷ (1.382817 − 1) = $547.85.
- Total Cost, the payment applied across all 60 months, = $32,871.13.
- Total Interest = 32,871.13 − 28,000.00 = $4,871.13.
