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

The free-coverage rule that runs the family math

Germany's GKV insures non-earning spouses and children at no extra cost through Familienversicherung (§ 10 SGB V). This isn't a discount or a bundle. It's structural. As long as the dependent's monthly income stays below €565 (or €603 if it's a minijob), they're covered free of charge under the spouse or parent in mandatory GKV (GKV-pflichtversichert). Children stay on family insurance until 18, or 25 if they're in education or training, and there's 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's 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's no "family rate", and the discount for adding family members is small. A PKV family-of-four typically lands at €1,200–€1,500/month gross before employer subsidy. The headline figure looks dramatic until the subsidy redistribution and tax math come in.

What PKV actually costs for kids

A PKV contract for a child looks structurally similar to an adult one but priced for the child's risk profile. Newborns and very young children land in roughly the same range as primary-school children; the staircase you might expect "by age" really doesn't kick in until adolescence. Typical broad-market figures for healthy children in 2026:

Newborn to about age 9: roughly €100–€200/month

Older child or teen: roughly €150–€250/month

The biggest single driver of where a given child sits within each band is whether the tariff includes a deductible (Selbstbeteiligung) or not. Same insurer, same age, same health: the no-deductible variant typically lands at the upper end, the deductible variant at the lower end. Other levers (dental tier, vision, foreign coverage, Chefarzt access in hospital) shift things further.

These are broad market ranges, not quotes. A real number for your child requires an individual calculation with the chosen tariff, deductible, and the insurer's underwriting check. Treat the figures here as orientation, nothing more.

The child's premium grows over time like any PKV contract, and the 10 % statutory Altersrückstellung surcharge under § 149 VAG starts at age 21, so children's premiums are flatter year-to-year than adults' until then.

There's a substantial advantage if you can place children in PKV by Kindernachversicherung under § 198 VVG: no health questions, no risk surcharges, no exclusions. We'll walk through that timing rule below.

Family scenarios, side by side

Three family setups that capture most of what mixed-system parents actually face. All figures are 2026 rates and total system cost (employer + employee combined for employees; self-employed pay the full amount themselves). PKV figures are mid-range market estimates for healthy applicants in a comprehensive tariff and need an individual calculation to be reliable for any specific family.

Family of four, single earner above the BBG

One earner above the BBG, partner at home with two healthy young children. GKV charges the with-kids cap; spouse and children ride along free under Familienversicherung. PKV needs a separate contract per family member, and the employer subsidy redistributes across the four contracts.

The total-cost gap is small and the actual difference depends on family size, ages, health profile, tariff choice, and how the employer subsidy redistributes across contracts. Net of the subsidy, GKV is typically ahead by roughly €80–€100/month for this profile.

Family of five, single earner above the BBG

Same earner profile, now with three children. The contrast with the family-of-four case is the structural point: GKV's bill stays flat as more children are added; PKV's bill grows linearly.

This is the flat-versus-linear pattern in one chart. From two children to three, GKV's cost doesn't move; PKV adds another full child premium. For one-earner households with three or more kids, the structural argument for Familienversicherung gets stronger with each additional dependent.

Dual-earner couple, both above the JAEG, no kids

A different shape entirely. With both partners individually eligible to choose, no Familienversicherung is on the table. The family question reduces to whether the couple plans to have children later, and how each spouse's tariff fits the long horizon.

For dual-earner couples planning to stay above the JAEG, PKV typically has the larger headroom in absolute euros. The tradeoff is the long-term commitment per spouse, which becomes structurally relevant if children arrive later (Kindernachversicherung sequencing, Mutterschutz timing, the parent-split rule covered below).

The pattern across the three

GKV's bill is flat in the number of dependents. PKV's bill is linear. A family of three pays the same in GKV as a family of five, while each new family member in PKV adds their own contract. For one-earner families with children, that arithmetic usually favours GKV; whether the broader benefit set across every member justifies the per-person cost depends on the family's priorities, health profile, and tariff choice. For dual-earner couples without kids, neither system has Familienversicherung in play and PKV's individually-priced contracts often come out clearly cheaper before any kids enter the picture.

The Mutterschutz, Elterngeld, and Krankentagegeld interplay

The pregnancy-and-leave sequence has the most complex GKV/PKV interplay of any life event, and it's the one where a misunderstanding costs real money.

Mutterschutz (§ 3 MuSchG): six weeks before birth, eight weeks after (twelve weeks for premature, multiple, or disabled births). For mandatory-GKV insured women, the Mutterschaftsgeld is up to €13/day from the Krankenkasse (§ 24i SGB V) for the entire Schutzfrist, plus the employer tops up to your previous net through the U2-Umlage system. Contributions are suspended during the Schutzfrist (§ 224 SGB V).

For PKV-insured women, the Mutterschaftsgeld is a one-off lump sum of up to €210 from the Bundesamt für Soziale Sicherung (§ 19 Abs. 2 MuSchG): not €210/month and not €210/week. That's the entire payout for the entire Schutzfrist. The PKV premium continues unbroken (no employer subsidy, because no salary is flowing). The employer's top-up is calculated against a fictional €13/day GKV rate, not against the real €210 lump.

The gap between €13/day GKV and €2.12/day PKV-equivalent (210 ÷ ~99 days) is roughly €11/day, or about €1,100 over a 14-week Schutzfrist. This is filled by your Krankentagegeld contract under § 192 Abs. 5 VVG, but only if you have one and only if the contract was in force at least 8 months before the Schutzfrist begins (most tariff conditions). KT in the Schutzfrist pays without requiring an Arbeitsunfähigkeit certificate.

Elternzeit and Elterngeld (BEEG): up to 3 years of unpaid leave per child, with Elterngeld at 65–67 % of average net before birth. The Elterngeld minimum is €300/month and the maximum is €1,800/month. The income threshold for entitlement, for births from 01.04.2025 onward, is €175,000 of taxable income per year, measured by the German tax-law concept of zu versteuerndes Einkommen (zvE), the figure that appears on your annual income-tax assessment after deductions. How the ceiling is applied depends on marital status: for jointly-assessed married couples and registered Lebenspartner it's the combined zvE of both partners; for unmarried partners and single parents each individual's zvE counts on its own. Above the limit, no Elterngeld at all.

PKV premiums continue during Elternzeit. There's no employer subsidy because no salary is flowing. Some family-friendly PKV tariffs offer up to 6 months of premium suspension (Beitragsbefreiung) during Elterngeld receipt; worth checking your specific tariff.

Kindernachversicherung: the 2-month window

A newborn enters the parent's PKV contract without underwriting, without risk surcharges, and without exclusions if three conditions all hold (§ 198 VVG, § 2 Abs. 2 MB/KK):

The insured parent has been with the same insurer for at least 3 months at the date of birth

The application is made within 2 months of birth (rückwirkend gültig from the day of birth)

The newborn's coverage is no broader than the parent's (you can't include the child in a Premium tariff if the parent is in Komfort)

The 2-month window is an Ausschlussfrist, strictly enforced by the courts. Miss it and you're back to standard PKV underwriting, which means health questions, possible risk surcharges, and possible exclusions for any congenital condition.

For pregnant PKV-insured women, the practical sequence is:

Within first weeks of pregnancy: confirm your tariff includes pregnancy care (Schwangerschaftsbetreuung); consider a tariff switch if it doesn't

During pregnancy: confirm the tariff has the congenital birth-defect clause (angeborene Geburtsschäden) in its AVB (some insurers, including Debeka, Württembergische, and AXA Active-Me, don't include it explicitly; get a written confirmation if your tariff is one of those)

Within 2 months after birth: submit the Kindernachversicherung application

If the parent is GKV-versichert, the newborn goes onto Familienversicherung at no cost, automatically once the birth is registered.

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

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), the income-comparison rule under § 10 Abs. 3 SGB V doesn't 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 an eingetragene Lebenspartnerschaft), § 10 Abs. 3 SGB V excludes the children from Familienversicherung when both of these conditions hold:

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

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 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 €100–€180/month each. For unmarried mixed-system parents, the question doesn't arise.

Family-friendly PKV tariffs: what to look for

If a family is going PKV anyway (typical for civil servants with Beihilfe, dual-earner couples both above the JAEG, or families relocating with established health profiles) the tariff features that matter most are:

Premium suspension (Beitragsbefreiung) in Elternzeit during Elterngeld receipt (typically 6 months; some Premium tariffs extend further)

Kinderkrankengeld analogous to § 45 SGB V (10 days per child per parent per year; 25 days total per parent)

Pregnancy care (Schwangerschaftsbetreuung) including pre-natal diagnostics beyond the standard catalogue (Nackenfaltenmessung, Ersttrimester-Screening, NIPT)

Course offerings (Kursangebote) such as antenatal classes, postnatal recovery (Rückbildung), and baby massage

Mutter-/Vater-Kind-Kur coverage (the statutory parent-and-child rehabilitation programme)

Krankentagegeld in Mutterschutz that meets § 192 Abs. 5 VVG (most do, but verify)

Congenital birth-defect coverage (angeborene Geburtsschäden) explicitly named in the AVB clause, which avoids dispute on day one of an unfortunate birth

These features add roughly €20–€60/month per adult contract versus a stripped-down comprehensive tariff. For a couple planning kids, that's worth it. For a couple done with family planning, it's not.

Practical timeline: pre-pregnancy to year one

A condensed checklist for expat families navigating the system, in order.

Pre-pregnancy:

Confirm both parents' insurance status: who is in mandatory GKV, who is voluntarily GKV-insured, who is in PKV

For dual-earner families above JAEG: decide whose contract the kids will live on if one switches systems

For PKV-bound parents: review tariff for pregnancy-care scope and the congenital-birth-defect clause

Activate or upgrade Krankentagegeld 8+ months before any planned conception (most KT contracts have a waiting period (Wartezeit) before they pay during Mutterschutz)

During pregnancy:

For PKV-insured women: confirm KT will pay during Mutterschutz under § 192 Abs. 5 VVG; some older tariffs require a separate rider

File the Mutterschaftsgeld application with the BAS (PKV) or Krankenkasse (GKV) 6 weeks before the expected birth date

For families considering a tariff switch: do it before the pregnancy is on file; switching with a Schwangerschaftsdiagnose on record will trigger underwriting

At birth and after:

Within 2 months: Kindernachversicherung application (PKV) or Familienversicherung registration (GKV)

File for Elterngeld within 3 months of birth (Elterngeldstelle of the federal state)

Update the Krankenkasse on the family insurance change

Year one:

Confirm the employer subsidy (Arbeitgeberzuschuss) is correctly distributed if multiple family members are in PKV

Review the tariff: premium suspension (Beitragsbefreiung) in Elternzeit should be active if applicable

For self-employed parents on voluntary GKV (freiwillige GKV): review the minimum assessment basis (Mindestbemessung) calculation if income dropped during leave

How to actually decide

The family-coverage decision is rarely about minimising this month's bill. It's about which mechanism survives the next decade: adding a child, losing a job, returning to work part-time, the second pregnancy.

For most expat families with one earner and children, GKV's Familienversicherung structure makes it the durable answer. The €1,226/month maximum contribution (Höchstbeitrag) (with-kids rate, of which an employee pays half) holds steady whether you have one child or four, and the family-coverage rule is enshrined in law. PKV's family math improves at the dual-earner-above-JAEG end of the spectrum and at the civil-servant end (where Beihilfe handles 80 % of children's costs), and it makes the most sense when health profiles allow comfortable underwriting.

If you'd like the actual math for your family's situation, including how the Mutterschutz timing, Kindernachversicherung deadline, and parent-split rule apply to you, book a consultation.
