About $1,336 a year for full coverage on a national average — 7% less than the $1,438 average car. Insurers rate the BMW 328d at an index of 93 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 across the BMW 328d: Comprehensive — theft, weather, vandalism, animals — carries its highest loss index at 135, while Property damage sits at 62. Those 73 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 2015 328d sells for a median $16,500, so a year of cover costs 8.1% of the car's value. Over 7 generations of data the index has fallen from 114 (2012-2014) to 93 (2018-2020). Calculated from 7 insurance-loss records and live US listing prices.
Why a 328d 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 $1,336: Liability (BI + PD) $641 · Collision $374 · Comprehensive $160 · Other (UM / PIP) $160.
How it changed by generation
Insurance-loss index of the 328d 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 328d has become cheaper to insure over time (-21 points).
What a 328d costs by state
Where you park matters as much as what you drive. The 328d's index applied to each state's average premium — the same car, the same cover, different postcode:
| State | 328d 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 |

BMW 328d insurance — frequently asked
How much is insurance for a BMW 328d?
About $1,336 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 93 applied to the US average premium.
Why is the 328d expensive or cheap to insure?
For the BMW 328d the costliest area is Comprehensive at an index of 135, covering theft, weather, vandalism, animals — against 62 for its cheapest. Insurers set premiums from claim history like that, not from the sticker price — which is why the BMW 328d lands at 93, not at what it costs new.
Is that a lot relative to the car's value?
A year of cover is 8.1% of what a 2015 328d sells for — $1,336 against a median price of $16,500. Cheap cars often show a higher percentage even when the dollar premium is lower, and at 8.1% the 328d sits on the expensive side of that trade.
Does its safety rating lower the premium?
Not directly. The 328d 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 328d can differ by hundreds between two drivers.
