An independent car-loan reference, reviewed by a working counselor.
kafinance.xyz publishes one calculator with two modes: payment-from-price and price-from-budget. Reviewed by a Detroit-based Accredited Financial Counselor specialising in auto finance, with prior experience underwriting auto loans at a regional captive lender.
§1.1Why this site exists
Most online car-loan calculators stop at “principal × rate × term.” They omit sales tax, doc fees, trade-in equity, and the negative-equity rollover that, in our experience, accounts for the majority of buyer surprises in the F&I office. kafinance.xyz handles the full picture and lets you flip the question: instead of “what does this car cost per month?”, “given my monthly cap, what vehicle price can I actually afford?”
§1.2Reviewer: Ezra J. Faulkner, AFC®
Experience. Ezra has spent thirteen years on the lender and counselor side of the auto-finance business. He started in 2012 as an auto-loan underwriter at a regional captive lender headquartered in Auburn Hills, Michigan, working through the post-financial-crisis return to a normalised auto-credit market. In 2017 he moved to a Detroit-area regional credit union, first as an indirect-lending analyst working with dealer partners, then as a member-side financial counselor focused on auto-loan structuring, refinancing, and the disentangling of negative-equity cycles. His current caseload runs to roughly 350 member consultations annually, dominated by buyers preparing to walk into a dealership and members looking to refinance an underwater loan into something workable.
Expertise. Ezra holds the Accredited Financial Counselor (AFC®) credential from the AFCPE, awarded 2018. He completed the National Automotive Finance Association (NAF) Certified Auto Finance Professional curriculum in 2015 and a Certificate in Consumer Lending from the Michigan Bankers Association in 2014. He read Economics at Michigan State University (BA, 2011) and completed an MBA in Finance at Wayne State University (2016). His areas of technical depth are auto-loan amortisation under conventional and balloon structures, the trade-in negative-equity rollover and gap-insurance interaction, and the dealer reserve / lender-rate-buy-up dynamics in indirect financing.
Authoritativeness. Ezra contributed to the AFCPE auto-finance counselling materials (2022 update) covering negative-equity rollover and refinance triggers. He has presented at the Michigan Credit Union League annual conference (2020, 2023) on auto-loan portfolio quality and member counselling. His commentary has appeared in the Detroit Free Press personal-finance column and in Credit Union Times. His AFC® credential is verifiable on the AFCPE public certificant directory.
Trustworthiness. Ezra reviews every calculation update on kafinance.xyz before publication and signs off on each editorial revision. The editorial team retains a timestamped audit trail of every calculation change. The credit-union counselling work associated with the named reviewer is fee-free to credit-union members; the work on kafinance.xyz is a public-benefit project undertaken in his capacity as an AFCPE-credentialed counselor. No dealership referrals, lender placements, or product affiliate links appear on the site.
§1.3Editorial process
The amortisation engine has been tested against the FCA-published amortisation tables for fixed-rate consumer credit and against the worked examples in the AFCPE auto-finance module. Editorial pages are drafted, technically reviewed by Ezra, fact-checked against primary sources (CFPB consumer guides, NAF practice materials, state DMV / DOT consumer pamphlets where state-specific), and timestamped at publication. Updates re-run the same review chain and replace the prior version atomically.
§1.4What we are not
We are not a dealer. We are not a lender. We do not refer buyers to specific dealerships, lenders, refinance brokers, or insurance providers. The calculator is a methodology tool for buyers preparing to negotiate; the editorial pages explain the components. For specific lending decisions consult an MAS-equivalent licensed loan officer or a non-profit credit counselor. kafinance.xyz is editorial; nothing on the site constitutes regulated financial advice within the meaning of the SEC Investment Advisers Act, the Truth in Lending Act, the CFPB’s rules on consumer credit, or comparable foreign regimes.
