Methodology

This calculator uses a fixed-rate amortizing loan model (equal monthly payments). Each payment includes interest and principal; the interest portion declines over time.

Inputs are amount financed, APR, and term in months. The monthly rate is approximated as APR ÷ 12. Actual lender disclosures may differ.

Calculation runs entirely in your browser. No personal data is transmitted or stored.

FinanzLogic Methodology (platform overview)

How we calculate

Monthly payment when APR > 0:

Payment = P × (r × (1 + r)n) / ((1 + r)n − 1)

  • P = amount financed (USD)
  • r = monthly rate = APR ÷ 12 ÷ 100
  • n = term in months (12–84)

At 0% APR: Payment = P ÷ n.

Excluded from this version: balloon/final payments, down payment input, trade-in, sales tax, doc fees, GAP, credit score, dealer reserve, variable rates, lease math.
