About $1,317 a year for full coverage on a national average — 8% less than the $1,438 average car. Insurers rate the GMC Terrain 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. Medical payments — medical bills for you and passengers — carries this car's highest loss index at 121, while Comprehensive sits at 81. That gap is the real reason behind the price, and it's the part a quote form never shows you. Among 78 suvs we hold data for, the Terrain ranks #33 from cheapest, below the class median of 94. Against what the car is worth the bill looks different again: a 2026 Terrain sells for a median $37,995, so a year of cover costs 3.5% of the car's value. Over 15 generations of data the index has climbed from 85 (2008-2010) to 92 (2022-2024). Calculated from 30 insurance-loss records and live US listing prices.
Why a Terrain 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 $1,317: Liability (BI + PD) $632 · Collision $369 · Comprehensive $158 · Other (UM / PIP) $158.
The Terrain against its class

Class as defined by insurers (SUVs), not by us — it groups cars by how they're actually driven and repaired. Median for this class is 94, roughly $1,352 a year.
How it changed by generation
Insurance-loss index of the Terrain 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 Terrain has become more expensive to insure over time (+7 points).
What a Terrain costs by state
Where you park matters as much as what you drive. The Terrain's index applied to each state's average premium — the same car, the same cover, different postcode:
| State | Terrain 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 Terrain
GMC Terrain insurance — frequently asked
How much is insurance for a GMC Terrain?
About $1,317 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 Terrain expensive or cheap to insure?
Its costliest area is Medical payments (index 121), which covers medical bills for you and passengers. Insurers set premiums from claim history like this, not from the sticker price.
Is the Terrain cheaper to insure than rivals?
It ranks #33 of 78 in the suvs class, where the median index is 94 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 3.5% of what a 2026 Terrain sells for (a median $37,995). Cheap cars often show a higher percentage even when the dollar premium is lower.
Does its safety rating lower the premium?
Not directly. The Terrain 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 Terrain can differ by hundreds between two drivers.
