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.
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.
Common questions
-
What does this calculator show?
An estimated monthly payment, total of payments, and total interest over the term you select. Use it to compare scenarios before talking to a lender.
-
Is the result a loan offer?
No. FinanzLogic does not originate loans. Lenders may apply different fees, credit tiers, or insurance requirements.
-
Should I enter APR or interest rate?
Enter APR when you have it — it reflects the cost of credit more completely than a nominal rate alone.
-
Are down payment or fees included?
Not automatically. Enter the amount you expect to finance after any down payment; taxes and dealer fees are excluded from this MVE tool.
