For context: reference-profile comparison
Not the same measure as the average premium above — the FOPH averages over all deductibles, models and age groups actually chosen; below is a single fixed profile (adults 26+, CHF 2,500 deductible, no accident cover, standard model). Main figure = average of this profile weighted by each insurer's membership; value in brackets = simple unweighted average.

Questions & answers
Frequently asked questions about the canton of Solothurn
Currently 25 health insurers offer basic insurance in the canton of Solothurn. We always show you all of them — regardless of whether we work with them.
Yes. The amounts shown are the gross premiums approved by the Federal Office of Public Health, minus the environmental levy refund per person — i.e. the amount you actually pay. The deduction is already included for every insurer on offer and changes nothing about the ranking of the offers.
2026: CHF 5.15 per month, or CHF 61.80 per year and person (FOEN).
The Federal Office of Public Health only divides a canton into several premium regions if healthcare costs differ significantly within it. That is not the case in the canton of Solothurn — premiums therefore apply uniformly across the canton, whether you live in Olten or another municipality.
