About $1,420 a year for full coverage on a national average — within a few percent of the $1,438 average car. Insurers rate the Porsche Boxster at an index of 99 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 across the Porsche Boxster: Collision — damage to your own car in a crash — carries its highest loss index at 132, while Property damage sits at 65. Those 67 points are the real reason behind the price, and they are the part a quote form never shows you. Among 15 sports cars we hold data for, the Boxster ranks #5 from cheapest, below the class median of 138. Against what the car is worth the bill looks different again: a 2003 Boxster sells for a median $13,000, so a year of cover costs 10.9% of the car's value. Over 19 generations of data the index has climbed from 81 (2004-2006) to 99 (2022-2024). Calculated from 19 insurance-loss records and live US listing prices.
Why a Boxster 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:

Estimated annual split at $1,420: Liability (BI + PD) $682 · Collision $398 · Comprehensive $170 · Other (UM / PIP) $170.
