A mathematical, data-driven approach to choosing the right deductible. Stop guessing and start calculating your optimal insurance setup.
The deductible (Franchise in German) is the amount you pay out of pocket each year before your insurer starts covering costs. Switzerland offers six fixed deductible levels for adults: CHF 300, 500, 1'000, 1'500, 2'000, and 2'500. For children, the options are CHF 0, 100, 200, 300, 400, 500, and 600.
The relationship is straightforward: higher deductible equals lower monthly premium. The logic is that you are agreeing to take on more financial risk in exchange for lower guaranteed costs. The question is: which deductible minimises your total annual expenditure given your expected healthcare usage?
After your deductible is met, you still pay a 10% co-payment (Selbstbehalt) on all further costs, up to CHF 700 per year for adults and CHF 350 for children. This means your maximum out-of-pocket (excluding premiums) ranges from CHF 1'000 (CHF 300 deductible + CHF 700 co-pay) to CHF 3'200 (CHF 2'500 deductible + CHF 700 co-pay).
Typical monthly premium differences for an adult in Zurich, Hausarzt model, 2026. Your canton's figures will differ, but the relative relationships are consistent.
| Deductible | Typical Monthly Premium | Annual Premium Cost | Max Out-of-Pocket (excl. premiums) | Total Annual Cost (worst case) |
|---|---|---|---|---|
| CHF 300 | CHF 410 | CHF 4'920 | CHF 1'000 | CHF 5'920 |
| CHF 500 | CHF 388 | CHF 4'656 | CHF 1'200 | CHF 5'856 |
| CHF 1'000 | CHF 354 | CHF 4'248 | CHF 1'700 | CHF 5'948 |
| CHF 1'500 | CHF 325 | CHF 3'900 | CHF 2'200 | CHF 6'100 |
| CHF 2'000 | CHF 302 | CHF 3'624 | CHF 2'700 | CHF 6'324 |
| CHF 2'500 | CHF 285 | CHF 3'420 | CHF 3'200 | CHF 6'620 |
The break-even point is the annual medical cost level where two deductible options result in the same total cost. Below this point, the higher deductible is cheaper. Above it, the lower deductible wins.
Premium savings with CHF 2'500: approximately CHF 1'500/year. Additional out-of-pocket risk: CHF 2'200. Break-even point: around CHF 1'500–2'000 in annual medical costs.
Verdict: If you spend less than about CHF 1'800 on medical care per year, the CHF 2'500 deductible saves you money. If you consistently spend more than CHF 2'000, the CHF 300 deductible is better.
Premium savings with CHF 1'500: approximately CHF 1'020/year. Additional out-of-pocket risk: CHF 1'200. Break-even point: around CHF 1'200–1'500 in annual medical costs.
Verdict: A solid middle-ground option. If you have occasional doctor visits (1–2 per year plus maybe one specialist visit), CHF 1'500 often comes out ahead or roughly even.
Premium savings with CHF 2'500: approximately CHF 1'236/year. Additional out-of-pocket risk: CHF 2'000. Break-even point: around CHF 1'600–1'900 in annual medical costs.
Verdict: The CHF 500 deductible is often overlooked. It offers a modest premium reduction while keeping out-of-pocket risk low. Good for those who want some savings without the full risk of CHF 2'500.
Your optimal deductible changes as you age. Here is a data-informed framework based on average healthcare utilisation by age group.
| Age Group | Avg. Annual Medical Costs | Recommended Deductible | Rationale |
|---|---|---|---|
| 19–25 | CHF 300–800 | CHF 2'500 | Lowest utilisation group. Premium savings almost always exceed additional risk. Put the savings into an emergency fund. |
| 26–35 | CHF 500–1'200 | CHF 2'500 or CHF 1'500 | Still low utilisation. CHF 2'500 wins for most. Consider CHF 1'500 if you have mild chronic conditions or plan pregnancy soon. |
| 36–50 | CHF 1'000–2'500 | CHF 1'500 or CHF 1'000 | Medical costs begin rising. The break-even shifts. Assess your actual spending from the prior 2–3 years before deciding. |
| 51–65 | CHF 2'000–4'500 | CHF 500 or CHF 300 | Chronic conditions, regular medications, and specialist visits become common. Lower deductible reduces volatility and total cost. |
| 65+ | CHF 4'000–10'000+ | CHF 300 | High utilisation makes the lowest deductible the clear financial winner. The premium savings from higher deductibles are dwarfed by out-of-pocket costs. |
The real power comes from optimising both your deductible and insurance model simultaneously. Here is how the savings stack up.
| Configuration | Monthly Premium (Zurich, 30yo) | Annual Premium | Savings vs. Baseline |
|---|---|---|---|
| Standard + CHF 300 deductible (baseline) | CHF 478 | CHF 5'736 | CHF 0 |
| Standard + CHF 2'500 deductible | CHF 348 | CHF 4'176 | CHF 1'560/year |
| Hausarzt + CHF 300 deductible | CHF 410 | CHF 4'920 | CHF 816/year |
| Telmed + CHF 300 deductible | CHF 395 | CHF 4'740 | CHF 996/year |
| Telmed + CHF 2'500 deductible | CHF 265 | CHF 3'180 | CHF 2'556/year |
| HMO + CHF 2'500 deductible | CHF 248 | CHF 2'976 | CHF 2'760/year |
The smartest approach for healthy adults: choose the CHF 2'500 deductible and deposit the monthly premium savings into a dedicated savings account. Within 2–3 years, you will have accumulated enough to cover even the worst-case deductible scenario — and the fund continues growing every year you stay healthy.
Year 1: You save approximately CHF 125/month (CHF 1'500/year) in premiums. Your emergency fund reaches CHF 1'500. If you need medical care this year, you pay out of pocket up to CHF 2'500 — net cost CHF 1'000 more than if you had chosen CHF 300 deductible.
Year 2: Your fund reaches CHF 3'000. You can now fully cover the CHF 2'500 deductible from savings. From this point forward, the CHF 2'500 deductible is strictly better financially, regardless of your health care needs.
Year 5: If you stayed healthy, your fund contains CHF 7'500. Even accounting for one bad year where you hit the full deductible, you are still thousands of francs ahead compared to paying the higher premium every month.
The general framework does not apply equally to everyone. Here are situations where the calculus changes.
If you are planning a pregnancy in the next 12 months, strongly consider the CHF 300 deductible. While pregnancy and childbirth themselves are exempt from the deductible, related complications, pre-natal specialist visits beyond the standard check-ups, and postnatal care for the mother may trigger deductible costs. The financial risk of a high deductible is not worth the premium savings during a pregnancy year.
If you take regular medication or see specialists quarterly, your annual medical costs likely exceed CHF 3'000–5'000. The CHF 300 deductible is almost certainly your best option. You will exceed any deductible level by March or April each year, so the only variable is the premium — and the CHF 300 deductible has the lowest total cost when medical expenses are high.
Children can have a CHF 0 deductible with minimal premium impact. For young children who visit the paediatrician frequently, CHF 0 is usually optimal. For healthy teenagers, a CHF 300–600 deductible can save a meaningful amount. Remember that the co-payment maximum for children is CHF 350 (not CHF 700), keeping the total out-of-pocket risk low even with a higher deductible.
Follow these four steps to determine your optimal deductible.
Check your insurer's annual statement (Leistungsabrechnung) for the past 2–3 years. What were your total medical costs each year? This is the best predictor of future costs.
Use a comparison tool to see the exact premium difference between deductible levels for your canton and insurer. Multiply the monthly difference by 12 for the annual savings.
If the annual premium savings exceed the deductible difference, the higher deductible is cheaper in ALL scenarios. If not, calculate at what medical cost level each option becomes cheaper.
Even if the math favours CHF 2'500, consider whether you can comfortably pay that amount in a bad year. If an unexpected CHF 2'500 bill would cause financial stress, choose a lower deductible for peace of mind.
