The 2024 Joint Forecast Model from the Auto Care Association in collaboration with MEMA Aftermarket Suppliers, reports that the U.S. aftermarket grew by 8.6% in 2023 to $391 billion with dealers’ service centers, auto parts stores, and general auto repair sectors all experiencing notable growth and outperforming initial estimates.

The 2024 Joint Forecast Model, is a comprehensive review and analysis of the size of the U.S. aftermarket, with the forecast for growth through 2027, and the trends in the industry shaping this growth. The Joint Forecast Model is prepared by S&P Global.

The forecast model provides a detailed examination of the automotive aftermarket landscape, offering insights into key influences and market trends shaping the industry’s changing size. Drawing on extensive research and analysis, the model delivers valuable projections for industry stakeholders, enabling informed decision-making and strategic planning.

Key Market Trends and Projections

The forecast model identifies several key market trends influencing the aftermarket, including:

• Labour Market Dynamics: Rising wages and a strong labour market are driving consumer spending, despite inflationary pressures.
• Inflation Outlook: Much of the growth is attributed to the industry’s ability to charge more for service and for parts to keep up with inflation which is expected to gradually recede, with rates returning to the target range by late 2025.
• Consumer Sentiment: While consumer sentiment remains low, spending levels have remained resilient. However, continued pessimism may pose risks to future spending patterns.
• Vehicle Sales and Fleet Growth: Despite fluctuations, new vehicle sales are projected to stabilize, contributing to the growth of the U.S. vehicle fleet.
• E-commerce Growth: E-commerce purchases of DIY parts continue to rise, reflecting shifting consumer preferences and increasing convenience.

Forecast for 2024 and Beyond

According to the 2024 Joint Forecast Model, 2023 was not dramatically different than in 2022 with respect to the key influences on the U.S. aftermarket. Inflation remained stubbornly high despite retreating gas prices, but a resilient consumer kept driving and spending across the economy including most importantly on their vehicle.

Elevated inflation remains a roadblock to potential federal rate cuts, but the labor market remains strong and wages continue to rise. As a result, despite some pessimism from the consumer, spending remains high which bodes well for the aftermarket.

The Joint Forecast Model predicts continued growth for the U.S. automotive aftermarket, with sales expected to increase by 5.9% in 2024. Looking ahead, average growth rates of 4.5% are forecasted for the period from 2025 to 2027, as inflationary effects subside and the aftermarket grows to $472 billion.
