For a young adult aged 19 to 25 with a deductible of 300 CHF and with accident cover, monthly premiums run from 334.25 CHF (CSS, Hausarztversicherung Profit) to 537.75 CHF (SLKK, Standard model): 122 offers from 25 health insurers.

On the cheapest offer (CSS, Hausarztversicherung Profit), the premium goes from 334.25 CHF a month with the 300 CHF deductible to 205.95 CHF with the 2'500 CHF deductible: 128.30 CHF less a month, 1'539.60 CHF a year. The 2'500 CHF deductible stays worthwhile up to around 2'011 CHF of medical costs a year; above that, the 300 CHF deductible works out cheaper.

For a young adult aged 19 to 25 with a deductible of 300 CHF and with accident cover, the cheapest premium per model is: standard model 357.65 CHF (Sanitas), family doctor / HMO 334.25 CHF (CSS), flexible model 344.35 CHF (Assura), telemedicine 343.15 CHF (Sanitas).

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 339.40 CHF at CSS (Hausarztversicherung Profit) gives 334.25 CHF after redistribution.

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.
