Health Insurance Costs by Age in Switzerland: What Changes at 19 and 26
Based on official FOPH premium data · Last updated 29 September 2026 (official 2027 premiums)
Swiss basic health insurance (KVG/LAMal) has three age categories: children (0–18), young adults (19–25), and adults (26+). Your premium jumps when you change category — but not on your birthday. The new premium applies from 1 January of the year after your 18th or 25th birthday. If you were born in 2008 or 2001, your premium changes on 1 January 2027.
The three age categories
The categories are set by federal law (Art. 61 KVG) and are identical at every insurer: children up to 18, young adults from 19 to 25, and adults from 26. Insurers must charge lower premiums for children and may grant a discount for young adults — in practice, all of them do. From 26, you pay the full adult premium with no age discount.
For 2027, the official FOPH average monthly premium is CHF 128.10 for children, CHF 338.80 for young adults, and CHF 487.60 for adults. That makes the step at 19 roughly CHF 210 more per month, and the step at 26 another CHF 150 per month — about CHF 1,790 more per year.

When exactly does the premium jump?
The category change always takes effect on 1 January following the relevant birthday. Two examples for the 2027 premium year: if you were born in 2008, you turn 18 during 2026 and pay the young adult premium from 1 January 2027. If you were born in 2001, you turn 25 during 2026 and pay the full adult premium from 1 January 2027. Born in 2009? Your jump comes one year later, on 1 January 2028.
Your deductible changes too
At the same moment, your deductible (Franchise) options change. Children can have a deductible between CHF 0 and 500 per year. From the young adult category onward, the adult range of CHF 300 to 2,500 applies. If you had the CHF 0 child deductible, you are moved to at least CHF 300 — and if you rarely see a doctor, choosing a higher deductible is one of the two biggest levers to offset the premium jump.
The jump is automatic — staying with the same insurer is not
Your insurer applies the new age category automatically and will show the higher premium in the policy it sends you in October. What many 18- and 25-year-olds miss: this is precisely the moment when comparing pays off most. Basic insurance coverage is identical at every insurer by law, so the only differences are the premium, your deductible choice, and your insurance model (family doctor, HMO, or Telmed — typically 10–20% cheaper than the standard model). To switch for 1 January, your cancellation must reach your current insurer by 30 November.

At 18 you still pay the child premium; from 1 January after your 18th birthday the young adult rate applies.
