Cost Analysis3 stats
01
OECD estimates show that vehicle repair and maintenance prices grew slower than overall inflation in recent periods in several member countries, indicating variable pricing power in aftermarket categories
02

03
The average stock-out cost for retailers is commonly estimated in the 4–8% of revenue range in supply chain economics studies, directly relevant to aftermarket parts where substitution is limited
Interpretation
Cost Analysis Interpretation
Cost pressures in the aftermarket appear manageable but uneven because OECD data shows repair and maintenance prices grew slower than overall inflation, US PPI for finished goods moved notably year over year in 2021–2022, and retailer stock out costs are often estimated at about 4–8% of revenue where limited substitution makes these losses especially costly.
