About $1,566 a year for full coverage on a national average — 9% more than the $1,438 average car. Insurers rate the Cadillac CT6 at an index of 109 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2018-2020).
The premium isn't spread evenly. Collision — damage to your own car in a crash — carries this car's highest loss index at 157, while Property damage sits at 83. That gap is the real reason behind the price, and it's the part a quote form never shows you. Against what the car is worth the bill looks different again: a 2017 CT6 sells for a median $15,995, so a year of cover costs 9.8% of the car's value. Over 4 generations of data the index has fallen from 115 (2015-2017) to 109 (2018-2020). Calculated from 6 insurance-loss records and live US listing prices.
Why a CT6 costs what it does
Insurers don't price a car with one number — they track losses separately for each kind of cover. An index of 100 is the average vehicle, so anything above means this model generates costlier claims of that type:
Read it as «where the money goes». A high Collision figure means these cars are expensive to repair after a crash; a high Comprehensive figure points at theft, weather and vandalism instead. Estimated annual split at $1,566: Liability (BI + PD) $752 · Collision $438 · Comprehensive $188 · Other (UM / PIP) $188.
How it changed by generation
Insurance-loss index of the CT6 across every generation in the data. Newer isn't automatically cheaper — driver-assist systems cut crash frequency, while sensors and aluminium panels push repair bills up:
Each point averages every recorded variant of that generation. The CT6 has become cheaper to insure over time (-6 points).
What a CT6 costs by state
Where you park matters as much as what you drive. The CT6's index applied to each state's average premium — the same car, the same cover, different postcode:
| State | CT6 est. / yr | vs national |
|---|---|---|
| Florida | +39% vs US | |
| Louisiana | +38% vs US | |
| New York | +32% vs US | |
| District of Columbia | +26% vs US | |
| Georgia | +21% vs US | |
| Texas | +20% vs US | |
| Wisconsin | -30% vs US | |
| Hawaii | -31% vs US | |
| Idaho | -32% vs US | |
| North Dakota | -33% vs US | |
| Vermont | -33% vs US | |
| Maine | -36% vs US |

More on the Cadillac CT6
Cadillac CT6 insurance — frequently asked
How much is insurance for a Cadillac CT6?
About $1,566 a year for full coverage at the national average, versus $1,438 for a typical car. That's the model's insurance-loss index of 109 applied to the US average premium.
Why is the CT6 expensive or cheap to insure?
Its costliest area is Collision (index 157), which covers damage to your own car in a crash. Insurers set premiums from claim history like this, not from the sticker price.
Is that a lot relative to the car's value?
A year of cover is 9.8% of what a 2017 CT6 sells for (a median $15,995). Cheap cars often show a higher percentage even when the dollar premium is lower.
Where does this data come from?
Insurance-loss indices published for real vehicles, combined with NAIC state average premiums. It's claim history, not a quote engine — so it shows what these cars actually cost insurers rather than what one company would offer you.
Will my own quote match this?
Treat it as a baseline for the car itself. Your figure also moves with age, driving record, deductible, mileage and ZIP code — the same CT6 can differ by hundreds between two drivers.
