Who we are

A calculator-first publisher.

AutoLoanLabs is an independent site focused on transparent auto finance math: amount financed, net trade-in equity, amortization, and scenario comparison. We do not sell loans, collect applications, or broker lender offers.

Content is reviewed by AutoLoanLabs Editorial for formula accuracy, disclosure clarity, and source citations. Contact: [email protected].

How we work

What we publish and what we do not.

Transparent formulas

Payment estimates use the standard fixed-rate amortization formula. Inputs and limitations are shown on each calculator page.

Trade-in equity first

Net trade-in equity equals trade-in value minus remaining payoff. Positive equity lowers amount financed; negative equity can raise it if rolled into the new loan.

Not financial advice

Results are planning estimates only. They are not loan approval, a credit offer, insurance advice, or a legal APR disclosure.

Editorial standards

Review criteria and update practices are documented in the editorial policy.
