About $1,600 a year for full coverage on a national average — 11% more than the $1,438 average car. Insurers rate the BMW 328xi at an index of 111 where 100 is a typical vehicle, based on how often and how expensively these cars actually generate claims (latest data covers 2014-2016).
The premium isn't spread evenly across the BMW 328xi: Comprehensive — theft, weather, vandalism, animals — carries its highest loss index at 156, while Personal injury (PIP) sits at 77. Those 79 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 328xi sells for a median $6,350, so a year of cover costs 25.2% of the car's value. Over 3 generations of data the index has fallen from 151 (2012-2014) to 111 (2014-2016). Calculated from 3 insurance-loss records and live US listing prices.
Why a 328xi 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 $1,600: Liability (BI + PD) $768 · Collision $448 · Comprehensive $192 · Other (UM / PIP) $192.
How it changed by generation
