How to save on health insurance in St. Gallen
Beyond the insurer you choose, your premium region and model drive the price. Moving from the average Standard premium to the cheapest available option saves roughly between CHF 1,284 and CHF 1,320 per year depending on your region. And because the zone is set by your postcode, an identical policy costs about CHF 708 per year more in the most expensive region than in the cheapest — for the same coverage.
The three levers, ranked by impact
- Insurance model. Telmed, HMO or Hausarzt models typically cost 10–25% less than the Standard free-choice-of-doctor model.
- Deductible. The CHF 2,500 tier beats CHF 300 if your yearly medical costs stay below roughly CHF 1,800–1,900 — which deductible to choose.
- Insurer. Same model and region, the spread between insurers is still CHF 50–150 per month.
Age also changes everything at 19 and 26 — see how age categories change your premium. For the national picture, see official 2027 premiums in every canton.
