The National Association of Insurance Commissioners (NAIC) 2022 Report on Profitability by Line and by State provides a comparison of the rates of return on net worth for the last 10 years (through 2021) for the property/casualty insurance industry. The table below compares this to Fortune magazine’s all-industry average, which represents an approximation based on a simple average of Fortune’s industry and service sectors.

Assuming that property/casualty companies needed to target at least a 6.1 percent rate of return on net worth from 2012 to 2021, this can be translated to a 7.1 percent rate of return on surplus, as shown below.

This already almost exceeds the California Department of Insurance’s average maximum allowable rate of return during this period—7.5 percent), without accounting for several factors that would require companies to seek even higher returns.
