The combined ratio for private passenger automobile insurance businesses in the past few years has been around 105%, which means they pay out $105 while take in $100 of premium.
If Tesla starts to report a combined ratio of 50%, the whole insurance world and investment community will notice Tesla cars indeed have less accidents.
How do they exist that way? There's overhead also...
I think they will partner with other insurer so they will not reveal all the details.
Combined ratio of 70% / pre marketing is healthy..and is the norm. Tesla doesn’t need to market it so that will significantly reduce the premium as well. Any saving due to better underwriting and additional data can all be pocketed.
To answer the "But how...?" - insurance companies make their profits by placing their premiums in other investments - e.g., the stock market. The best mind I ever encountered in the insurance company belittled the other firms in the property & casualty industry by relying on this tactic; he claimed that the only way to stay healthy in the long run was to keep the combined ration below 100%. HIS firm was the only one able to do so, decade after decade - through the end of the last millennium. In order not to derail this thread, I'll not mention who that was, 'tho some of you may know or divine the answer. It is
not Buffett.
Also, "overhead" is taken into account in the combined ratio; needn't be looked for elsewhere.
If
@Pras "70%" number is indeed the norm these days, then either (1) marketing must
really take a bite (I doubt this); or (2) premiums are waaaaay higher than they should be (that's possible); or (3) these are data from some insurance sector other than the P&C. Remember I have been out of the investment world for a quarter-century so
some of what I write is hysterical. As well as historical.
Penultimately, as
@tivoboy (I think) mentioned, Tesla Insurance would be sloughing off some of the risk to Munich Re or Swiss Re or General Re. but I've no good answer as to how Tesla will maneuver the differing Insurance Regulatory Agencies of the 50 states....
except that neither Mr Musk nor anyone else said that this product will be available in the USofA, correct?
And finally, as far as the "some states require catholicism amongst insurees - like drunks, repeat offenders &c (don't recall who wrote this)..." - if this is true, how does a behemoth like USAA exist? USAA is set up to insure officers of the various branches of the US military and their families. The rationale behind their famously low premiums has been that this pool is a more responsible set of drivers than the population as a whole. Has something changed since this Rip Van Winkle nodded off? (
Wouldn't surprise me.....). If it
is still the case, then I think we can view the Tesla Insurance model as being very, very similar to that of USAA. But on steroids.
