is an important metric for insurance companies.
Premiums/(loss payments+overhead) is how you determine the combined ratio. Profits would include interest income so in many instances the actual business of writing insurance is a small loss but due to the investments the company will be profitable.
A couple of years ago State Farm had a combined ratio of like 120% (expenditures on claims+overhead outpaced collected premiums) and I believe they still we profitable due to the high interest rates and investment returns.
