Family Health Insurance in Germany: GKV or PKV? (2026 Math)

How does Familienversicherung work in GKV?

Familienversicherung, the GKV's free co-insurance for family members under § 10 SGB V, lets a non-earning spouse and children ride along on the working parent's GKV contract at no extra cost. The 2026 income limit for the dependant is €565/month (€603 for a minijob). Children stay covered until 18, or 25 if still in education; there is no upper age limit for non-earning spouses.

The savings compound fast. For one earner supporting a non-earning spouse and two kids, GKV charges only what the earner would pay anyway. At the BBG cap in 2026 that is a maximum contribution (GKV-Höchstbeitrag) of €1,226/month (with-kids rate), of which an employee pays half (~€613) with the employer covering the other half. The other three family members add €0/month. The household's total contribution is identical to a single mandatory-GKV insured with no dependents.

PKV has no equivalent. Every member needs an individual contract, with individual underwriting at entry. There is no "family rate", and the discount for adding family members is small. That difference in mechanism, flat versus per-person, is what the rest of this guide prices out.

What if one parent is GKV and the other is PKV?

Marital status decides this before income does. Three configurations exist: both parents in GKV (children ride along free), both in PKV (children need their own contracts), and the mixed case. In a mixed household, unmarried parents have a free choice, while married couples run into an income test under § 10 Abs. 3 SGB V that can force the children onto the PKV parent.

A common setup: one partner is salaried under the JAEG (so in mandatory GKV); the other is self-employed (so chose PKV). Whether the children can ride along free on the GKV parent's Familienversicherung depends first on marital status, and only then on income.

If the parents are not married (and not in an eingetragene Lebenspartnerschaft, a registered civil partnership), the income-comparison rule under § 10 Abs. 3 SGB V does not apply at all. The Bundesverfassungsgericht confirmed this in 2011 (1 BvR 429/11): the resulting unequal treatment of married versus unmarried parents is settled law. In practice, the children go on the GKV parent's Familienversicherung at no cost regardless of who earns more, or, if the family prefers the broader benefit set, they can be placed in PKV. The choice is open.

If the parents are married (or in a registered civil partnership), § 10 Abs. 3 SGB V excludes the children from Familienversicherung when both of these conditions hold:

1. The PKV parent's regular income exceeds 1/12 of the JAEG (the threshold for compulsory GKV, distinct from the BBG used elsewhere in this guide), and
2. The PKV parent's regular income is higher than the GKV parent's.

If both apply, the children must be insured under the higher-earning PKV parent and cannot use Familienversicherung. The Krankenkasse measures "regular income" using current monthly gross for employees and the most recent Einkommensteuerbescheid (annual tax assessment) for self-employed parents, meaning that for the self-employed half of a typical mixed-system couple, the comparison rests on the previous year's tax assessment.

The implication: for a married mixed-system family, the earnings split between the two parents drives whether the kids cost €0 or €150–€250/month each. For unmarried mixed-system parents, the question does not arise.

What does PKV cost per family member?

A PKV contract for a child in 2026 runs from about €150/month for an entry-level tariff to €250/month at the top benefit level. What moves the number is the benefit scope you choose and whether the tariff carries a deductible (Selbstbeteiligung), not the child's age. Each parent adds their own contract on top: typical 2026 ranges for healthy applicants are €300–€400/month at age 25–30 and €450–€650/month at age 35–40 for a comprehensive tier.

A newborn can be added to a parent's PKV contract without any health check at all, via Kindernachversicherung under § 198 VVG, provided the application is filed within two months of birth. That deadline is absolute, and if both parents are privately insured there is no public fallback: how newborn enrolment works covers the conditions and what missing it costs.

Set against a single-earner GKV household, the comparison for a family of four looks like this.

Net of the subsidy, GKV is ahead by roughly €80–€100/month for this profile. The structural point matters more than the number: GKV's bill is flat in the number of dependants, PKV's is linear. Add a third child and the GKV figure does not move at all, while PKV adds another full premium of around €150. For one-earner households planning several children, that gap widens with every birth.

When is PKV the better call for a family?

In three situations, and none of them is the classic single-earner household. PKV wins when both parents earn above the JAEG, when the earning parent is self-employed, and when the family is complete. The common thread: each case removes the thing that makes GKV cheap for families, which is free Familienversicherung paid for by an employer-subsidised contribution.

Both parents above the JAEG. If both partners are individually eligible to choose, there is no free family coverage to give up, and the comparison flips hard. Two spouses at the GKV cap pay roughly €2,522/month combined in 2026, while two healthy thirty-somethings in a mid-range comprehensive PKV tariff land near €800/month before the employer subsidy. That is the widest gap in the whole family picture, and it applies until children arrive.

The earning parent is self-employed. This is the case most families miss. A self-employed parent in voluntary GKV (freiwillige GKV) pays the full contribution with no employer to split it, up to about €1,226/month at the 2026 cap. PKV prices on age and health rather than income, so a healthy self-employed parent often pays less overall even after adding a contract per child. The employer subsidy that makes GKV attractive for employees simply does not exist here.

The family is complete. PKV's weakness for families is that cost grows with each person added. Once you know no more children are coming, that weakness stops compounding, and the calculation becomes a straightforward per-person comparison rather than an open-ended one.

There is also the break-even case. At roughly €100/month for a family of four, some families conclude the private benefit set is worth it: shorter waits for specialist appointments, broader dental cover for the children, and a single or double room in hospital. That is a preference, not a maths error, and it is a legitimate reason to choose PKV.

If you do go the PKV route with children, the tariff features that matter most are premium suspension during Elterngeld, a benefit analogous to Kinderkrankengeld (§ 45 SGB V), expanded pregnancy care, Krankentagegeld that pays during Mutterschutz under § 192 Abs. 5 VVG, and explicit cover for congenital birth defects in the policy terms. These add roughly €20–€60/month per adult contract over a stripped-down tariff. For a couple planning children, that is worth paying. For a couple who are done, it is not. The Krankentagegeld point in particular has a deadline attached: what maternity leave actually pays on private cover works through the timing, which has to be handled before conception.

How do I actually decide?

Start with two questions: how many earners does the household have, and is either of them self-employed? Those two answers move the decision further than any tariff comparison. A single-earner family with children usually lands in GKV; a dual-earner couple above the JAEG, or a household whose earner is self-employed, usually lands in PKV.

The family-coverage decision is rarely about minimising this month's bill. It is about which mechanism survives the next decade: adding a child, losing a job, returning to work part-time, a second pregnancy. GKV's €1,226/month maximum contribution holds steady whether you have one child or four, and the family-coverage rule is written into law. PKV's advantage is concentrated where that rule gives you nothing, and it comes with a long-horizon commitment per person.

These pieces interlock differently depending on marital status, the income split between parents, whether you plan more children, and how long you stay in Germany. If you would like the actual math for your family's situation, book a consultation.
