Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The size was built upward from estimated online order volumes across component categories, tire and wheel units, and accessory items, multiplied by average realized transaction prices observed on OEM-affiliated storefronts and third-party marketplaces. Country-level shipment counts from parts distributors and logistics carriers anchor the volume side; average order values are drawn from marketplace listing data and payment-processor transaction summaries. The resulting build is checked against disclosed e-commerce channel revenue reported by publicly listed auto-parts retailers and marketplace operators; where a country's bottom-up total diverged from a disclosed figure by more than a limited margin, the underlying order-volume or price assumption for that category was revised rather than the two figures averaged.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews target category managers at OEM parts divisions who set online catalogue and pricing policy, merchandising leads at third-party marketplaces who see cross-brand order data, procurement managers at fleet operators and repair shop chains who run recurring digital orders, and customs or trade compliance specialists who handle cross-border parts shipments. Sampling weights North America and Europe most heavily, where OEM and marketplace e-commerce channels are most mature and disclosure is most consistent, with a smaller but deliberate sample in China, India and the Gulf states to capture platform types and buyer behavior that differ from the more established markets.

Secondary sources, this report

Desk research draws on customs trade data filed under HS code 8708 for motor vehicle parts and accessories, national statistical office retail e-commerce surveys such as the US Census Bureau's e-commerce retail sales report, aftermarket trade body benchmarks published by the Auto Care Association and its regional counterparts, and investor disclosures from publicly listed marketplace operators and auto-parts retailers that break out online channel revenue. Vehicle parc and registration data from national transport authorities supplement the demand side, and marketplace listing and pricing data collected directly from major platforms inform the average order value assumptions used in the bottom-up build.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast carries forward the ongoing shift of parts and accessory purchases from physical counters to online channels, scaled against vehicle parc growth by region and the pace at which fleet and repair-shop buyers move recurring orders onto digital procurement portals. Pricing behavior assumes gradual normalization of freight and last-mile delivery costs that were still elevated in the historical period. The forecast holds if online penetration keeps advancing at a decelerating but positive rate consistent with adjacent retail categories and if vehicle parc growth in Asia Pacific and Latin America does not slow materially from its recent trend.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

The 2020-2024 build was back-tested against recorded retail e-commerce growth rates in adjacent categories, including general retail and consumer electronics, to confirm the historical curve was not overstated relative to categories with more complete public data. Segment share shifts, particularly the move toward electrical and infotainment components, were reviewed against category specialists familiar with online parts retailing. Sensitivities were tested against a slower online-penetration path, where fleet and repair-shop digitization lags, and a faster one, where marketplace consolidation accelerates buyer migration from physical counters sooner than the base case assumes.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for the component-type and vehicle-type splits in North America and Europe, where marketplace and OEM channel disclosures are frequent enough to check the bottom-up build directly. It is softer for the platform-type and end-user splits in the Middle East, Africa and parts of Latin America, where fewer operators report online channel figures separately from total retail revenue. The main structural risk is a shift in freight or tariff costs affecting cross-border parts flow, which would change realized prices enough to warrant revisiting the underlying volume and price assumptions.
