About $1,899 a year for full coverage on a national average — 32% more than the $1,438 average car. Insurers rate the Chevrolet Cobalt at an index of 132 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2008-2010).
The premium isn't spread evenly across the Chevrolet Cobalt: Medical payments — medical bills for you and passengers — carries its highest loss index at 184, while Comprehensive sits at 89. Those 95 points are the real reason behind the price, and they are the part a quote form never shows you. Against what the car is worth the bill looks different again: a 2010 Cobalt sells for a median $3,650, so a year of cover costs 52% of the car's value. Over 7 generations of data the index has fallen from 184 (2004-2006) to 132 (2008-2010). Calculated from 7 insurance-loss records and live US listing prices.
Why a Cobalt 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 $1,899: Liability (BI + PD) $912 · Collision $532 · Comprehensive $228 · Other (UM / PIP) $228.
How it changed by generation
Insurance-loss index of the Cobalt 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 Cobalt has become cheaper to insure over time (-52 points).
What a Cobalt costs by state
Where you park matters as much as what you drive. The Cobalt's index applied to each state's average premium — the same car, the same cover, different postcode:

|---|---|---|
| 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 |

Chevrolet Cobalt insurance — frequently asked
How much is insurance for a Chevrolet Cobalt?
About $1,899 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 132 applied to the US average premium.
Why is the Cobalt expensive or cheap to insure?
For the Chevrolet Cobalt the costliest area is Medical payments at an index of 184, covering medical bills for you and passengers — against 89 for its cheapest. Insurers set premiums from claim history like that, not from the sticker price — which is why the Chevrolet Cobalt lands at 132, not at what it costs new.
Is that a lot relative to the car's value?
A year of cover is 52% of what a 2010 Cobalt sells for — $1,899 against a median price of $3,650. Cheap cars often show a higher percentage even when the dollar premium is lower, and at 52% the Cobalt sits on the expensive side of that trade.
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 Cobalt can differ by hundreds between two drivers.
