About $1,319 a year for full coverage on a national average — 8% less than the $1,438 average car. Insurers rate the GMC Sierra at an index of 92 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2022-2024).
The premium isn't spread evenly. Property damage — damage you cause to other property — carries this car's highest loss index at 116, while Personal injury (PIP) sits at 67. That gap is the real reason behind the price, and it's the part a quote form never shows you. Among 22 pickups we hold data for, the Sierra ranks #11 from cheapest, below the class median of 95. Against what the car is worth the bill looks different again: a 2026 Sierra sells for a median $76,800, so a year of cover costs 1.7% of the car's value. Over 38 generations of data the index has fallen from 100 (2004-2006) to 92 (2022-2024). Calculated from 196 insurance-loss records and live US listing prices.
Why a Sierra 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 $1,319: Liability (BI + PD) $633 · Collision $369 · Comprehensive $158 · Other (UM / PIP) $158.
The Sierra against its class

Class as defined by insurers (Pickups), not by us — it groups cars by how they're actually driven and repaired. Median for this class is 95, roughly $1,368 a year.
How it changed by generation
Insurance-loss index of the Sierra 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 Sierra has become cheaper to insure over time (-8 points).
What a Sierra costs by state
Where you park matters as much as what you drive. The Sierra's index applied to each state's average premium — the same car, the same cover, different postcode:
| State | Sierra 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 GMC Sierra
GMC Sierra insurance — frequently asked
How much is insurance for a GMC Sierra?
About $1,319 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 92 applied to the US average premium.
Why is the Sierra expensive or cheap to insure?
Its costliest area is Property damage (index 116), which covers damage you cause to other property. Insurers set premiums from claim history like this, not from the sticker price.
Is the Sierra cheaper to insure than rivals?
It ranks #11 of 22 in the pickups class, where the median index is 95 against this car's 92. Cheaper rivals are listed in the chart above.
Is that a lot relative to the car's value?
A year of cover is 1.7% of what a 2026 Sierra sells for (a median $76,800). Cheap cars often show a higher percentage even when the dollar premium is lower.
Does its safety rating lower the premium?
Not directly. The Sierra holds 5 stars from NHTSA, but crash-test performance and repair cost are priced separately — a car can protect occupants well and still be costly to fix.
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 Sierra can differ by hundreds between two drivers.
