VINTrakID Glossary
Plain-language definitions of every proprietary term you'll see in your dashboard, reports, and the methodology page — each one connected to its established industry concept.
What does VINTrakID's glossary cover?
The glossary defines VINTrakID's seven proprietary terms — Equity Position Index, VIN-based Depreciation Curve, Residual Value Threshold, First-Touch Attribution, BuyerSignal, Diminished Value Susceptibility, and Recall Impact Score — and maps each one to its established industry analog so the methodology is fully transparent.
- Each term lists its industry analog (LTV, residual value, intent data, etc.).
- Every entry is anchor-linkable and emits a DefinedTerm JSON-LD record.
- Definitions are informational only — never used for credit, lending, or insurance decisions.
Equity Position Index
Industry analog: Loan-to-Value Ratio (LTV)
A 0–100 numeric indicator of how a specific vehicle is currently positioned within its peer market, expressed as relative equity strength rather than absolute dollar value.
The Equity Position Index (EPI) compresses several inputs — segment-level market price drift, regional inventory depth, recall exposure, and depreciation-curve deviation — into a single position score. It is conceptually analogous to a loan-to-value (LTV) ratio used by lenders, but VINTrakID computes it from market and event data tied to your VIN rather than from a loan balance. EPI is informational; it is not a credit, lending, insurance, or appraisal output.
VIN-based Depreciation Curve
Industry analog: Standard depreciation schedule
The expected month-by-month value trajectory a specific VIN should follow given its make, model, year, trim, mileage band, and regional segment, used as a baseline for detecting unusual value movement.
A VIN-based Depreciation Curve replaces the industry-standard one-size-fits-all depreciation schedule (e.g. "20% in year one, 15% per year after") with a VIN-specific reference curve. Significant deviation above or below the curve is what drives an alert — not the underlying depreciation itself. Curves are recalibrated as fresh market data arrives.
Residual Value Threshold
Industry analog: Residual value in leasing & lending
The minimum estimated market value, expressed as a percentage of MSRP, below which a vehicle is flagged as "at risk" for trade-in or refinance windows.
In leasing and lending, "residual value" is the asset-backed price the lender expects at lease end. VINTrakID adapts this concept for owners: the RVT is the point at which the modeled market value drops below the level where typical refinance, trade-in, or lease-buyout options are still favorable. RVT thresholds are segment-specific and surface as an alert band rather than a single hard number.
First-Touch Attribution
Industry analog: Marketing attribution models
The rule used by the VINTrakID partner referral system: the very first partner code (`?ref=`) a visitor arrives with is permanently locked to that user account; subsequent partner links never overwrite it.
First-Touch Attribution is a standard marketing-attribution model — VINTrakID applies it strictly so that the partner who originally introduced a customer continues to receive credit through subsequent registrations, paid subscriptions, and BuyerSignal events for up to 365 days. The locked attribution is bot-filtered before it is stored.
BuyerSignal
Industry analog: Intent data / In-market signals
An anonymized indication that a vehicle owner has entered a market-readiness window (typical pre-trade or pre-sale behavior). Surfaced only to authorized partners and only with explicit owner opt-in.
BuyerSignal is VINTrakID's equivalent of "intent data" in B2B marketing — but applied to vehicle ownership, anonymized at the source, and gated by explicit consumer opt-in. Partners never receive raw PII; they receive aggregated readiness windows tied to a partner-specific token. Owners can revoke BuyerSignal sharing at any time from their dashboard.
Diminished Value Susceptibility
Industry analog: Diminished value (insurance)
A tier (Low / Moderate / High / Extreme) indicating how sensitive a specific vehicle's perceived market value is to a hypothetical future accident, derived from segment, brand positioning, repair complexity, and documentation expectations.
Diminished Value (DV) is an established insurance concept measuring the loss in market value of a vehicle after it has been damaged and repaired. DVS does NOT measure actual diminished value — it estimates how susceptible a vehicle's class and brand are to that loss BEFORE any incident occurs, so owners can understand the equity exposure they already carry. It is informational and never used for insurance, lending, or eligibility decisions.
Recall Impact Score
Industry analog: NHTSA recall severity classifications
A numeric weight (0–100) reflecting how strongly an open manufacturer recall is expected to influence a vehicle's market position, factoring in recall severity, remedy availability, segment scrutiny, and time-since-issued.
NHTSA classifies recalls but does not score market impact. RIS layers the public NHTSA recall feed with VINTrakID's market-impact model: an unresolved safety-critical recall on a luxury segment (where buyer scrutiny is high and remedies often involve specialized parts) scores materially higher than the same campaign on a high-volume daily driver. RIS feeds the Equity Position Index but is also surfaced on its own so owners understand why a number moved.
