Automotive aftermarket sales statistics: U.S. light-duty market size and growth
U.S. light-duty automotive aftermarket sales totaled $413.7 billion in 2024, growing 5.7% from the prior year, according to Auto Care Association’s June 2025 release about its Factbook. The release characterized that growth as in line with the 5.9% projection made the previous year. These figures describe the light-duty aftermarket, not the entire automotive economy or every vehicle class.
The distinction matters when comparing market totals. The same release projected that the combined U.S. light-, medium-, and heavy-duty aftermarket would reach $664.3 billion in 2028. That broader figure should not be read as a light-duty-only total. The release also forecast 5.1% light-duty growth for 2025; that was a forecast published in June 2025, not a reported 2025 result.
Automotive aftermarket sales statistics: the forecast horizon
A separate Auto Care Association release, issued the day before the Factbook announcement, put the U.S. light-duty aftermarket at a projected $435 billion in 2025 and said it was expected to top $500 billion by 2028. Both are forecasts from June 2025. They offer a longer-range view than the reported 2024 total, but they should not be treated as realized sales.
The public releases give multiple forward-looking figures: 5.1% projected light-duty growth in 2025, a $435 billion light-duty market projection for that year, and a broader $664.3 billion forecast in 2028 across light-, medium-, and heavy-duty vehicles. These measures have different scopes and are not interchangeable. In particular, the $664.3 billion figure covers more vehicle classes than the $500 billion light-duty projection.
Automotive aftermarket sales statistics: service and dealer channels
The publicly reported channel figures point to a modest shift in market share. In 2024, the service channel retained a 0.6 percentage-point gain it had taken from the dealer channel. Over the longer period cited in the June 2025 release, the dealer channel had lost 1.4 percentage points since 2017.
These are changes in share, measured in percentage points—not growth rates in sales dollars. The public release does not provide the underlying channel shares or enough detail here to quantify each channel’s sales. The figures support a directional observation about share movement, not a conclusion that dealer sales declined in absolute terms or that service sales rose by a particular amount.
Automotive aftermarket sales statistics: online parts sales forecasts
Auto Care Association’s public summary of its Joint E-commerce Trends and Outlook Forecast separates online parts sales excluding third-party marketplaces from the broader total including them. For 2025, it forecast approximately $23 billion in U.S. automotive aftermarket parts e-commerce sales excluding marketplaces, compared with $44.6 billion including them. Those totals use different channel definitions; the larger figure is not a like-for-like estimate of direct retailer e-commerce alone.
The summary also projected a compound annual growth rate above 5% for the total online automotive aftermarket over 2020–2030. That is a forecast over a ten-year period, not a measured annual growth rate for any single year. For engine parts, online ticket amounts—the amounts represented by transactions—were reported as having grown at a CAGR of up to 6% from 2021 through 2025, with most of that increase attributed in the summary to inflation. A higher ticket amount therefore does not by itself establish equivalent growth in units sold or inflation-adjusted demand.

Automotive aftermarket consumer spending and vehicle maintenance costs
Government household expenditure data offer context for vehicle-related budgets, but they do not measure aftermarket purchases alone. The Bureau of Labor Statistics reported average annual “other vehicle expenses” of $4,206 per U.S. consumer unit in 2024, up from $3,845 in 2023. The category represented 5.4% of average annual expenditures in 2024, compared with 5.0% in 2023. “Other vehicle expenses” is a broad expenditure category, so it should not be equated with spending on aftermarket parts or repair services.
Transportation as a whole accounted for 17.0% of average annual consumer-unit expenditures in 2024. This broader category gives a sense of transportation’s place in household budgets, but it includes more than vehicle maintenance and aftermarket goods.

Repair and parts prices are not sales growth
The BLS Consumer Price Index adds another useful, but distinct, measure. The CPI for motor vehicle maintenance and repair rose 6.2% in the 12 months ending December 2024, following a 7.1% increase in the 12 months ending December 2023. The CPI for motor vehicle parts and equipment rose 1.3% in the year ending December 2024; in the prior 12-month period, it had fallen 1.2%.
These are changes in consumer prices, not changes in aftermarket revenue, transaction counts, or quantities purchased. Price increases can affect nominal spending and average transaction amounts, but the CPI figures alone do not show how much of market growth came from prices versus volume. Vehicle insurance prices rose 11.3% over the same 12 months ending December 2024, but insurance is not aftermarket sales and is best treated as a separate vehicle-cost measure.
