On the cheapest offer (CSS, HMO (health practice)), the premium goes from 530.45 CHF a month with the 300 CHF deductible to 411.15 CHF with the 2'500 CHF deductible: 119.30 CHF less a month, 1'431.60 CHF a year. The 2'500 CHF deductible stays worthwhile up to around 1'891 CHF of medical costs a year; above that, the 300 CHF deductible works out cheaper.

For an adult aged 26 or over with a deductible of 2'500 CHF and without accident cover, the cheapest premium per model is: standard model 502.15 CHF (Assura), family doctor / HMO 411.15 CHF (CSS), flexible model 411.35 CHF (Assura), telemedicine 427.85 CHF (Groupe Mutuel – Mutuel).

Why is the FOPH-approved premium higher than the price shown?

The large amount is the FOPH-approved premium — the same one as on priminfo.admin.ch, shown under each price — less the redistribution of the environmental levies (the CO₂ levy and the VOC incentive tax). In 2026 every insured person in Switzerland receives 61.80 CHF, which their insurer deducts from the premium invoices: 5.15 CHF a month, the same amount for everyone, whatever the insurer, the model or the deductible. The ranking is therefore unchanged. This amount is not necessarily your final invoice: your canton’s individual premium reduction or a discount for annual payment are added where they apply. For example, the approved premium of 416.30 CHF at CSS (HMO (health practice)) gives 411.15 CHF after redistribution.

Until when can I change health insurer for 2026?

Your cancellation must reach your current insurer by 30 November 2025 at the latest; the change takes effect on 1 January 2026. The premiums on this page are those approved by the FOPH for 2026.
