The rubric — weighted
How we score and rank.
Each provider in our comparison stack is scored against the factors below. The factor weights sum to 100% and don't change based on which carrier or lender is being reviewed. Total weight: 100%.
APR competitiveness
40%Weighted by the lender's published rate range vs. the national tier-by-tier benchmark for 781+, 661–780, 601–660, and <600 FICO bands. Higher rate-to-tier ratio = lower score.
Data source: Experian State of the Auto Finance Market, Q4 2025
Fees + dealer-markup transparency
20%Origination fees, documentation fees, prepayment penalties, and whether the lender publishes a dealer-markup ceiling. Lenders that suppress these in marketing are penalized.
Data source: Lender published rate sheets + CFPB consumer complaint database
Loan term flexibility
15%Minimum + maximum terms, support for non-standard terms (e.g. 42/54), and used-vehicle-age limits.
Customer experience
15%Aggregate satisfaction across J.D. Power Auto Finance studies, BBB complaint resolution rate, and Trustpilot review volume + verified rating.
Data source: J.D. Power Consumer Financing Satisfaction Study, BBB, Trustpilot
Approval breadth
10%Minimum FICO accepted, support for first-time buyers, support for self-employed/1099 income. Lenders that approve thinner files score higher.
How we audit ourselves
Three guardrails on every methodology change.
Source verification
Every weight reflects a published consumer-finance data source (NAIC, III, Bankrate, Experian, NCUA, FTC) cited inline on the calculator or comparison surface.
Audited rubric
Rubric weights are reviewed by editorial leadership at least quarterly. Changes are logged below and version-tagged in the data registry.
Independence guard
Affiliate compensation never influences the rubric. Disclosed on every page where it applies.
