Private vs statutory health insurance — the honest comparison

The one difference everything follows from

The statutory system (GKV) charges you according to your income, up to a ceiling beyond which the contribution is capped. Your health plays no part. Nor does your age.

Private insurance (PKV) charges according to entry age, health status and the cover you choose. Your income is irrelevant.

Practically everything else follows from that single difference. It explains why private cover is often markedly cheaper for well-paid, healthy, younger people without dependants — and why it usually becomes more expensive for single-earner families.

What private cover genuinely does better

The advantage is real but often misrepresented. It is not that statutory patients receive poor treatment — basic medical care in Germany is good in both systems. The differences sit elsewhere:

• Guaranteed cover. What your policy states applies. In the statutory system the legislator defines the benefit catalogue and has changed it repeatedly.
• Waiting times for specialists. The difference most noticeable in daily life.
• Dental work. Between the statutory fixed subsidy and good private reimbursement there are quickly four-figure sums.
• Hospital options. Single or twin rooms and senior-consultant treatment can be insured.
• Premium refunds. Claim nothing for a year and many tariffs refund several monthly premiums.

The four questions that decide it

Forget online premium comparisons. The decision hangs on four questions — and if one of them points the wrong way, the rest rarely matters.

1. Do you want children, and will a partner stay at home?

The single most important question. The statutory system covers a non-earning spouse and children at no additional cost. Privately, every person pays their own premium. A family of four on one income quickly pays a multiple.

2. How secure is your income long term?

The private premium stays the same even if your income collapses; the statutory contribution falls with it. If you are self-employed with volatile earnings or planning a career break, take this seriously.

3. Are you healthy — demonstrably?

The health assessment looks back several years. Pre-existing conditions lead to surcharges, exclusions or rejection. Note that seemingly harmless entries in your medical record — a back treatment, a course of therapy — can matter.

4. Could you carry the premium as a pensioner?

The private premium does not track your pension. If your retirement provision is tight, this question belongs before the decision — not thirty years after it.

When private cover becomes a trap

• Young employees just above the threshold. Cross it narrowly this year and you may fall below it next year, which triggers compulsory statutory insurance again.
• Family planning within a few years. The cost advantage flips with the first child, certainly with the second.
• Switching purely on today's premium. A cheap entry premium says little about thirty years of premium development. Cheap starter tariffs are often the most expensive contracts long term.
• Age over 45 without a clear advantage. The later the entry, the higher the premium and the shorter the period for building ageing reserves.
• An open-ended stay in Germany. Private cover only pays off over time. If you may leave in a few years, that argues strongly against it.

Premiums in old age

The most common worry, and the worst explained. First the clarification: your premium does not rise because you get older. Age is priced in from the start. It rises because healthcare costs rise overall — medical progress, new treatments, more expensive drugs. Statutory contributions rise for the same reason.

Three mechanisms dampen the increase:

• Ageing reserves. In younger years you pay more than you cost; the surplus is invested and drawn on later.
• Statutory surcharge. Paid until 60, it feeds back to relieve premiums from 65.
• The right to switch tariffs within your insurer — more on that below.

If you are already privately insured

Changing insurer is rarely the answer: your ageing reserves largely stay with the old company, so you effectively start again. The stronger lever sits inside your existing insurer.

A tariff switch under § 204 VVG is your statutory right. You may move into any tariff of your insurer with equivalent cover, your reserves transfer in full, and a new health assessment is only permitted for additional benefits.

Many people pay an outdated, closed tariff for years while a modern tariff with equal or better cover exists in the same company — often considerably cheaper. Insurers rarely point this out unprompted.

The middle path: supplementary cover

For most people tempted by private cover, this is actually the better answer. You stay statutory — keeping the advantages for family, income volatility and reversibility — and close the gaps that cost most in practice:

• Dental supplement — by far the most worthwhile addition
• Hospital supplement — consultant treatment and room choice
• Outpatient modules — glasses, alternative practitioners, screening

This costs a fraction of a full switch, can be cancelled at any time, and closes no doors.

Conclusion

Private cover is neither a better nor a worse system — it is a different one. It rewards high, stable income and good health, and it penalises starting a family and income shocks. Work that through beforehand and you make a good decision. Follow the entry premium and you often do not.
