A Look at Commercial Collision Claim Trends

Posted by

To aid those weathering the uncertainties of how 2021 will impact the commercial collision industry, we at PPG are sharing some benchmarking insights and trends, compiled from our ADJUSTRITE ® Commercial Estimating system, from 2018 thru 2020— including both insurance and shop estimates from the United States and Canada. For all metrics, except severity, the information excludes known total losses.

Severity trends reflect an industry experiencing increased complexity or
year-over-year increases.
In contrast to the approximate 4.7% increase in claim severity from 2018 to 2019, excluding total losses, there was a 2.7% increase from 2019 to 2020. The average claim severity in 2020 was $8,620.
(For all estimates including total losses, there was a 10.4% increase in severity in 2020, compared to 2019, with an average claim severity of $10,288.)

Total parts’ dollars also showed year-over-year increases. For 2018 to 2019, the average total parts’ dollars increased 3.3%. There was a 2.9% increase for 2019 to 2020.

Average total parts ‘dollars per estimate in 2020 was approximately $4,120. Total labor dollars also saw increases year-over-year.




From 2018 to 2019, total labor dollars increased 6.3%, and there was a 3.7% increase in 2020, over 2019. Table 1 provides a 3-year view of sales mix percentages.

Sales Mix Percent for CY 2018 – CY 2020



With labor dollar increases outpacing others, it is critical to review the labor mix percentages over the past three years, which averaged 61.8% body, 3.5% frame, 10.7% mechanical, 0.2% miscellaneous and 23.8% paint.

The 3-year trend saw a move of less paint and body to more mechanical and miscellaneous labor percentages. Table 2 provides a view of each year.

Table 2: Labor Mix Percent for CY 2018 —CY 2020

94.0% of estimates with body labor. The 3-year average percentages of estimates for each labor type were as follows:

    • 7.9% with frame labor
    • 23.9% with mechanical labor
    • 1.2% with miscellaneous labor
    • 71.0% with paint labor.

From 2019 to 2020, there were increases in estimates with frame and mechanical labor, and a decline in estimates with paint, body, and miscellaneous labor. Table 3 provides a view of each year.

Table 4:
Average Labor Dollars for CY 2018—CY 2020
A review of the 3-year trend for average labor dollars shows that all labor types experienced a year over year increase except frame and mechanical labor dollars. Frame labor dollars were flat from 2018 to 2019, however were down 5.4% from in 2020. Mechanical labor dollars increased in 2019 over the previous year, however remained flat in 2020. Miscellaneous labor dollars saw a double- digit increase of 11.5% from 2019 to 2020. Table 4 provides a view of each year.

When comparing average parts dollars for 2020, the OEM average part cost was $247—recycled parts was $1,433, and aftermarket new was $335. The split between repair and replace labor dollars in 2019 and 2020 amounted to 42% for repair and 58% for replace. “Front” was the most often flagged primary impact area in 2020, followed by “Right Front” then “Left Front.”

The 3-year average for sublet dollars per estimate is $711, with the average down 1.5% in 2020. From 2018 to 2020, paint and material dollars showed year over year increases of 6.6% and 5.2% respectively. Average paint and material dollars per estimate in 2020 numbered $547.

The average total supplement cost was approximately $3,800 in 2020 The percent of estimates with supplements increased from 25.9% in2018 to almost 28% in 2019. Last year saw that percentage drop to 24.2%, with 71.9% of those estimates having only have one supplement.
