Swiss Health Insurance Franchise Guide 2026: Which Deductible Saves You the Most Money?

When I was building the localized Swiss salary and cost-of-living tools for ProCalc, I had to parse the mandatory basic health insurance (Grundversicherung / LAMal) structure. As I analyzed the premium brackets, I realized that Swiss residents face a major optimization problem: choosing the right annual franchise level (deductible) between CHF 300 and CHF 2,500.

Because the relation between premium savings and out-of-pocket costs is non-linear, choosing a middle franchise is almost always a mathematical mistake. I wrote a script to model this tradeoff and find the exact breakeven point based on expected annual medical expenses. That optimizer became the basis of the Swiss Health Insurance Franchise Optimizer. In this guide, I'll explain the math behind the Franchise levels, the 10% co-insurance cap (Selbstbehalt), and how to choose the right plan to save money.

1. Swiss Health Insurance Structure (KVG 2026)

The Swiss basic health insurance plan consists of three main components: the Monthly Premium, the Franchise (Deductible), and the Co-insurance (Selbstbehalt / Quote-Part).

+-------------------------------------------------------------------+
|               SWISS KVG HEALTH INSURANCE STRUCTURE                |
+-------------------------------------------------------------------+
| FRANCHISE (Deductible): 6 levels — CHF 300 to CHF 2,500          |
|   You pay 100% of all medical costs UP TO the franchise amount   |
|                                                                   |
| CO-INSURANCE (Selbstbehalt / Quote-Part): 10% of excess costs    |
|   You pay 10% of costs ABOVE the franchise, capped at CHF 700/yr |
|                                                                   |
| MAXIMUM OUT-OF-POCKET ANNUAL COST:                                |
|   CHF 300 franchise: CHF 300 + CHF 700 cap = CHF 1,000 max       |
|   CHF 2,500 franchise: CHF 2,500 + CHF 700 cap = CHF 3,200 max   |
+-------------------------------------------------------------------+

Once you exceed your chosen franchise amount in a calendar year, you do not immediately get free healthcare. You must pay 10% of any additional costs (co-insurance) up to a maximum of CHF 700 per year for adults. After reaching this cap, basic insurance covers 100% of all further medical expenses for the rest of the year.

2. All Six Franchise Levels (2026)

There are six standard franchise levels for adults in Switzerland. The premium discount is regulated by the Federal Office of Public Health (FOPH/BAG), meaning that higher franchises must offer a legally mandated discount.

Franchise Level	Lower Premium vs CHF 300	Max Out-of-Pocket	Best For
CHF 300 (minimum)	—	CHF 1,000	Frequent medical users, chronic illness, pregnancy
CHF 500	~CHF 200/yr	CHF 1,200	Generally not recommended (suboptimal mathematically)
CHF 1,000	~CHF 600–800/yr	CHF 1,700	Generally not recommended (suboptimal mathematically)
CHF 1,500	~CHF 900–1,200/yr	CHF 2,200	Generally not recommended (suboptimal mathematically)
CHF 2,000	~CHF 1,200–1,600/yr	CHF 2,700	Generally not recommended (suboptimal mathematically)
CHF 2,500 (maximum)	~CHF 1,540/yr	CHF 3,200	Rarely ill, emergency-only users, healthy adults

The "Only Two Choices" Rule of Thumb

In Switzerland, health economists agree that only the CHF 300 and CHF 2,500 franchises make financial sense. The intermediate franchises (CHF 500, 1,000, 1,500, 2,000) are mathematically suboptimal because the premium discount you get for choosing them is too small compared to the extra risk you assume. If you expect annual medical expenses under CHF 2,000, choose CHF 2,500. If you expect expenses over CHF 2,000, choose CHF 300.

3. Step-by-Step: Franchise Break-Even Formula

The key question is: "At what annual medical spending does a lower franchise become cheaper?"

Break-Even Medical Spending = Premium Savings ÷ Franchise Risk

For a Zurich 30-year-old adult in 2026 (illustrative premiums):

• CHF 300 franchise monthly premium: CHF 450 → Annual: CHF 5,400
• CHF 2,500 franchise monthly premium: CHF 322 → Annual: CHF 3,864
• Annual premium saving from CHF 2,500 franchise: CHF 1,536

Let's look at three scenarios based on these premiums:

Scenario A: Medical expenses = CHF 0 (perfect health year)

• CHF 300 plan: CHF 5,400 premium only = CHF 5,400 total cost
• CHF 2,500 plan: CHF 3,864 premium + CHF 0 franchise = CHF 3,864 total cost
• CHF 2,500 franchise wins by CHF 1,536

Scenario B: Medical expenses = CHF 1,000

• CHF 300 plan: CHF 5,400 + CHF 300 franchise + CHF 70 co-insurance (10% of remaining CHF 700) = CHF 5,770
• CHF 2,500 plan: CHF 3,864 + CHF 1,000 franchise + CHF 0 co-insurance = CHF 4,864
• CHF 2,500 franchise still wins by CHF 906

Scenario C: Medical expenses = CHF 5,000

• CHF 300 plan: CHF 5,400 + CHF 300 + CHF 700 co-insurance cap = CHF 6,400
• CHF 2,500 plan: CHF 3,864 + CHF 2,500 + CHF 250 co-insurance (10% of remaining CHF 2,500) = CHF 6,614
• CHF 300 franchise wins by CHF 214 — break-even crossed!

4. Alternative Insurance Models: Save 15-25% More

To save even more money on basic insurance, you can select an alternative path for accessing care rather than the standard model (which allows you to go directly to any specialist):

• HMO Model (Health Maintenance Organization): You agree to always consult a designated HMO clinic first. If you need a specialist, the HMO doctor will refer you. This model offers discounts of 15% to 25% on monthly premiums.
• Telmed Model (Telemedicine): You must call a medical hotline (like Medgate) before visiting a doctor. The hotline agent will advise you on the next steps and refer you if necessary. This model is highly flexible and offers discounts of 15% to 20%.
• Family Doctor Model (Hausarzt): You commit to always consulting your chosen general practitioner (GP) first. If you require a specialist, your GP must write a referral. This model offers discounts of 10% to 15%.

Combining the CHF 2,500 franchise with an HMO or Telmed model is the absolute cheapest way to get basic health insurance coverage in Switzerland.

5. Tips to Lower Your Swiss Health Insurance Costs

1. Opt out of Accident Coverage (Unfalldeckung): If you work for a Swiss employer for at least 8 hours per week, you are automatically covered for both occupational and non-occupational accidents by your employer. You can remove accident coverage from your private health insurance, saving 5% to 10% on your monthly premium.
2. Compare on Priminfo: Do not use commercial broker websites that charge commissions. Use the official federal comparison portal run by the government: priminfo.admin.ch. It lists all premiums without bias.
3. Pay Annually or Semi-Annually: Some insurers offer a 0.5% to 2% discount if you pay your premiums for the entire year or half-year upfront rather than monthly.
4. Request Subsidies (Prämienverbilligung): If your household income falls below a certain threshold (which varies by canton), you are entitled to a premium reduction subsidy. Check with your cantonal social security office to apply.

Frequently Asked Questions (FAQ)

Can I change my franchise level once per year?

Yes. You can switch your franchise level by October 31 each year, with the new franchise taking effect on January 1 of the following year. You can also switch your Krankenkasse insurer (while keeping the same or different franchise) by November 30 for January 1 effect.

Does the Swiss franchise apply to every medical visit?

The franchise is a cumulative annual total, not a per-visit charge. Once your cumulative medical expenses exceed your franchise amount for the year, you pay only the 10% co-insurance on additional costs — up to the CHF 700 co-insurance cap.

Are dentist costs covered by Swiss basic insurance?

No. Standard dental care is not covered by Swiss basic insurance (KVG/LAMal). Dental treatments are either paid fully out-of-pocket or covered by optional supplementary dental insurance (Zusatzversicherung), which must be purchased separately.

What is the Swiss health insurance subsidy (Prämienverbilligung)?

Low-to-moderate income Swiss residents are eligible for cantonal premium subsidies (Prämienverbilligung / Réduction de primes). Eligibility thresholds and subsidy amounts vary by canton. In 2026, approximately 2.5 million Swiss residents receive premium reductions. The subsidy is applied directly to reduce your monthly premium bill.

Do children have different franchise rules?

Yes! Children under 18 have lower franchise options: CHF 0, CHF 100, CHF 200, CHF 300, CHF 400, CHF 500, or CHF 600. The co-insurance cap for children is also lower at CHF 350/year. Children's premiums are approximately 40–50% lower than adult premiums.

What does a Swiss supplementary insurance (Zusatzversicherung) add?

Supplementary insurance covers extras not included in basic insurance: dental care, private/semi-private hospital room, alternative medicine (Komplementärmedizin), international health coverage, glasses and contact lenses, and psychological/therapy sessions. Unlike KVG, supplementary insurers can reject applicants based on pre-existing conditions.

What happens if I can't afford my medical bills in Switzerland?

If you are unable to pay your premiums or out-of-pocket franchise costs, you must contact your municipal social service office immediately. In Switzerland, failing to pay health insurance can lead to a suspension of non-emergency medical services (blacklisting by cantons) and debt collection proceedings (Betreibung).

Is pregnancy covered by the franchise?

No! Maternity services, prenatal checks, childbirth, and postnatal care are completely exempt from the franchise and co-insurance. You do not pay anything out-of-pocket for standard pregnancy-related medical treatments from the 13th week of pregnancy onwards. Therefore, you do not need to switch to a CHF 300 franchise just because you are planning a pregnancy.
