The short answer
Swiss basic insurance pays for the same catalogue of medical services everywhere, yet premiums can vary by hundreds of francs a month. The reason is that the law standardises the benefits, not the price. Insurers set their own premiums and must have them approved each year by the Federal Office of Public Health (FOPH), and those premiums are graded by canton, by premium region within some cantons, and by age group — children (0–18), young adults (19–25) and adults (26 and over). On top of that grading, the quoted figure depends on which insurer you hold the contract with, and on three settings you decide yourself: your franchise, your insurance model, and whether accident cover is included. What never enters the calculation for basic insurance is your income, your sex or your state of health.
Key takeaways
- Basic-insurance benefits are fixed by the Health Insurance Act (KVG/LAMal). Premiums are not: each insurer calculates its own and submits them to the FOPH for approval.
- Premiums are graded by canton of residence, because each insurer must cover its costs in each canton separately.
- Five cantons (Bern, Graubünden, Lucerne, St. Gallen, Zurich) are split into three premium regions; six (Basel-Landschaft, Fribourg, Schaffhausen, Ticino, Vaud, Valais) into two. Everywhere else, one region applies.
- There are only three age classes. Adults from 26 pay the same age-based premium regardless of whether they are 30 or 70.
- Within basic insurance, health status, sex and income play no part in the premium you are quoted.
- The factors you control are the franchise, the model, whether accident cover is included, and which insurer you hold the contract with.
- Discounts are capped by law: a maximum of 70 per cent of the additional risk you take on with a higher franchise, and no premium may fall below 50 per cent of the ordinary premium for your age group and region.
Why identical benefits do not mean identical premiums
Compulsory basic insurance is defined by federal law. Every insurer must accept every applicant, and every insurer pays for the same catalogue of services. That standardisation stops at the price.
Each insurer calculates its own premiums for the coming year, based on the healthcare costs it expects to pay, its risk-compensation position, its administrative costs and its solvency requirements. It then submits those premiums to the FOPH, which approves them only if they cover expected costs in that canton without producing excessive reserves. The result is a legally supervised price, not a uniform one.
Two consequences follow. First, an insurer whose insured population in a canton generates higher costs has to price accordingly. Second, because approval is checked per canton, the same company can be among the cheaper options in one canton and among the more expensive in another. If the mechanics of the system are new to you, our guide to how Swiss health insurance works sets out the framework.
Why premiums differ between cantons
Premiums follow costs, and healthcare costs differ markedly between cantons. Every insurer must ensure its premium income covers healthcare expenditure in each canton, so cantonal cost levels feed directly into cantonal premiums.
The FOPH names three recurring drivers of these differences:
- Demographics. Cantons with an older population use more medical services.
- Share of outpatient treatment. Outpatient care is currently financed entirely from premiums, so a higher outpatient share pushes premium-financed costs up.
- Density of care providers. More doctors, therapists and hospitals in a region tends to mean higher healthcare spending.
This is also why moving house across a cantonal border can change your premium even when nothing else about you changes. Your place of residence is the decisive factor, not where you work or where your employer is registered.
Why your municipality can matter: premium regions
Within larger cantons, costs vary between city and countryside. The law allows a canton to be subdivided into two or three premium regions, and the Federal Department of Home Affairs (FDHA) sets both the regional boundaries and the maximum permitted premium differences between regions, in the FDHA Ordinance on Premium Regions (SR 832.106).
| Number of premium regions | Cantons |
|---|---|
| Three | Bern, Graubünden, Lucerne, St. Gallen, Zurich |
| Two | Basel-Landschaft, Fribourg, Schaffhausen, Ticino, Vaud, Valais |
| One | All other cantons, including Aargau, Basel-Stadt, Geneva, Solothurn, Thurgau, Zug and the remaining cantons |
In a multi-region canton, the municipality you live in determines which region applies. Two households a few kilometres apart, insured with the same company under the same conditions, can therefore be quoted different premiums entirely legitimately.
How age affects the premium — and how it does not
Basic insurance uses three age classes only:
- Children: 0–18. Substantially lower premiums, no franchise required, and reduced cost sharing.
- Young adults: 19–25. A separate age category, for which insurers may set lower premiums than for adults aged 26 and over. Insurers may also offer this group a different set of optional franchises.
- Adults: from 26. One single class.
The last point surprises many new residents. Within basic insurance, a healthy 28-year-old and a 72-year-old living at the same address, with the same insurer, franchise and model, pay the same premium. Age-related cost differences are handled behind the scenes through risk compensation between insurers, not by charging older policyholders more.
Two age transitions are worth diarising, because the premium changes automatically: from the calendar year after the 18th birthday, and from the calendar year after the 25th. Supplementary insurance under the Insurance Contract Act (VVG/LCA) follows entirely different rules and can price by age and health — the distinction is explained in basic vs supplementary insurance.
How the franchise changes the premium
The franchise is the annual amount you pay yourself before the insurer starts contributing. The standard franchise is CHF 300 for adults and CHF 0 for children. Higher optional franchises reduce the premium: adults can choose CHF 500, 1,000, 1,500, 2,000 or 2,500, and children CHF 100 to CHF 600.
The discount is not open-ended. By law, the reduction may not exceed 70 per cent of the additional risk the policyholder assumes. Choosing a CHF 2,500 franchise instead of CHF 300 means accepting up to CHF 2,200 more risk, so the annual premium reduction is capped at 70 per cent of that amount. Insurers may grant less, and often do; there is no universal percentage saving, which is why any figure quoted as a fixed "saving" for a higher franchise should be treated with caution.
Insurers are not obliged to offer every franchise level, and they may offer different levels to young adults. A franchise change only ever takes effect at the start of a calendar year. The full mechanics, including how to judge which level suits you, are covered in what the Swiss franchise is and how it works.
How the insurance model changes the premium
The law permits insurers to offer special forms of insurance in which you accept a limitation on your free choice of provider in exchange for a lower premium. In practice these appear as:
- Standard model — free choice of doctor, and the reference premium.
- Family doctor model — you consult a designated GP first.
- HMO model — you use a specified group practice or health centre.
- Telmed model — you call a medical advice line before most treatments.
- Bonus models — the premium falls over years in which you claim no services.
Two points are often missed. The discount reflects each insurer’s own arrangements with the providers behind the model, so the same model name can carry very different discounts at different companies. And the reduction is bounded by the same statutory floor as everything else: no premium may fall below 50 per cent of the ordinary premium with accident cover for that age group and premium region, however the discounts are combined. The practical trade-offs are set out in our comparison of family doctor, HMO and Telmed models.
Why accident cover changes the quoted figure
Basic health insurance includes accident cover by default, and the quoted premium reflects that. People who work at least eight hours a week for an employer in Switzerland are fully insured against accidents under the Accident Insurance Act (UVG/LAA) through that employer, and may apply in writing to their health insurer to suspend accident cover. The premium is then reduced accordingly, with effect at the earliest from the first day of the month after the application is received.
People who are not employed, or who work fewer than eight hours a week — children, students, pensioners, and those not in paid work — are generally not covered under the UVG and keep accident cover within their health insurance. There are important exceptions: people drawing unemployment benefit are insured against accidents through the unemployment insurance scheme, and after employment ends UVG cover continues for a limited period (currently 31 days after entitlement to at least half a salary ceases).
This single setting explains a surprising number of "identical" quotes that differ. A comparison in which one person’s premium excludes accident cover and the other’s includes it is not comparing the same product. It also matters when circumstances change. If employment ends or hours drop below the threshold, accident cover generally has to be reinstated with the health insurer — but not necessarily from day one: UVG cover runs on for a limited period after the salary entitlement ends, and people receiving unemployment benefit remain accident-insured through the unemployment insurance scheme. The point at which the health insurer's accident cover is needed therefore depends on the individual situation, so it is worth clarifying the date with the insurer rather than assuming an immediate gap.
Why two similar people can still be quoted different premiums
When two people with comparable profiles receive different quotes, the explanation is almost always one of the following:
| Factor | Affects the basic premium? | Can you influence it? |
|---|---|---|
| Canton of residence | Yes | Only by moving |
| Premium region (municipality) | Yes, in 11 cantons | Only by moving |
| Age class (0–18, 19–25, 26+) | Yes | No |
| Insurer | Yes | Yes — you may change insurer |
| Franchise | Yes | Yes, from 1 January |
| Insurance model | Yes | Yes, subject to the insurer’s conditions |
| Accident cover included or suspended | Yes | Yes, if UVG-insured through an employer |
| State of health, medical history | No | Not applicable |
| Sex | No | Not applicable |
| Income or wealth | No — but may qualify you for a cantonal premium subsidy | Via a subsidy application |
| Nationality or permit type | No | Not applicable |
Income deserves a note of its own. It does not change the premium an insurer charges, but it can change what you actually pay. Cantons reduce premiums for people in modest economic circumstances, and for families on low and middle incomes cantons must reduce children’s premiums by at least 80 per cent and the premiums of young adults in education by at least 50 per cent. Each canton decides eligibility, amounts and procedure; some grant reductions automatically, others require an application.
Expert Insight — It is worth separating the parts of the premium you can move from the parts you cannot. Canton, premium region and age class are fixed inputs: they set the level you start from. Insurer, franchise, model and accident-cover status are settings, and they are the only levers available in an ordinary year. That distinction also explains why blanket statements such as "switching saves you X per cent" rarely hold — the same switch produces a different result in Zurich and in Appenzell Innerrhoden, and a franchise discount capped at 70 per cent of the additional risk is an upper limit, not a promise. The reliable method is to hold the settings constant, compare like with like, and then check one variation at a time.
Common misconceptions
- "A higher premium buys better cover." Not in basic insurance. The benefit catalogue is identical at every insurer.
- "Insurers charge more as I get older." Not within basic insurance beyond age 26. Older policyholders are accounted for through risk compensation between insurers.
- "My premium depends on my medical history." Not for basic insurance. Supplementary insurance under the VVG/LCA is a different matter and is underwritten.
- "The cheapest canton must have the best insurers." Premium levels reflect local healthcare costs, not insurer quality.
- "Premium subsidies are only for people on very low incomes." Thresholds are cantonal, and families with children often qualify without expecting to. Check with your canton of residence.
- "My employer’s canton counts." Only your place of residence determines the cantonal premium.
How to compare premiums correctly
Because so many variables sit inside a single quoted figure, a fair comparison requires holding them steady:
- Start from your actual address, since the canton and, where applicable, the premium region derive from it.
- Use priminfo.admin.ch, the official federal premium calculator published by the FOPH. It is anonymous, independent and free of advertising.
- Fix the franchise at one level across all quotes before comparing companies.
- Fix the model too, and check which practices or networks stand behind it locally.
- Set accident cover the same way for every quote — included, or suspended if you qualify.
- Compare the annual figure, and consider the cost sharing you would bear in a year with treatment, not only the monthly premium.
- Check whether a cantonal premium subsidy applies to your household before concluding what you will actually pay.

Frequently asked questions
Why is my premium higher than my colleague’s, though we earn the same?
Income plays no part in basic-insurance premiums. The difference will come from your canton or municipality of residence, your age class, your insurer, or the franchise, model and accident-cover settings on your policy.
Does my premium rise every year because I get older?
No — a premium does not rise simply because you have had another birthday. Basic insurance uses three age categories, and from 26 onwards adults all remain in the same category, so ageing within it does not change the premium. What can change it is moving into a different statutory age category: in the calendar year after your 18th birthday and again after your 25th. Beyond that, annual changes reflect rising healthcare costs and each insurer's approved premiums, not your individual age.
Will my premium change if I move?
Yes, if you move to another canton or, within Bern, Graubünden, Lucerne, St. Gallen, Zurich, Basel-Landschaft, Fribourg, Schaffhausen, Ticino, Vaud or Valais, to a municipality in a different premium region. Notify your insurer of the new address.
How much can a higher franchise reduce my premium?
There is no fixed percentage. The law caps the reduction at 70 per cent of the additional risk you take on, and insurers may grant less. Check the actual figures for your age group and premium region.
Can my premium be reduced to almost nothing by combining discounts?
No. However a higher franchise, a restricted-choice model and suspended accident cover are combined, the premium may not fall below 50 per cent of the ordinary premium with accident cover for your age group and premium region.
Can an insurer charge me more because I have a chronic condition?
Not for basic insurance. Insurers must accept every applicant and may not price by health status. Supplementary insurance under the VVG/LCA is underwritten separately and may be restricted, surcharged or declined.
Why do premiums rise every year?
Premiums follow costs. The FOPH attributes rising costs to the ageing population, medical advances, new medicines and treatments, and increasing use of healthcare services.
Where to go from here
Understanding why a premium is what it is usually makes the next decision easier: whether the franchise still fits how you use healthcare, whether the model is right for your household, and whether a cantonal subsidy applies.
