Faster or slower than the rest?
CSS rose +38.9 % over the period, against +47.1 % for the cheapest insurer in the same place. The gap narrowed — which does not mean this insurer is the cheapest today, only that it climbed more slowly.
The year that hurt — The steepest year-on-year jump was 2024: +7.8 % in one go.
Figures for an adult, CHF 300 deductible, accident cover included — the only profile defined identically across all twelve years. Each year this is the lowest premium the insurer offered, all models combined.
