Short Answer

Public insurance premiums are based on a percentage of your income, while private premiums depend on your age and health status.

Switching from private back to public insurance is legally restricted once you exceed a certain age or income threshold.

What Most Expats Don't Realize

You chose a private plan because it was €200 cheaper per month when you were young and healthy. Ten years later, you had two children and discovered that you had to pay a separate premium for each of them, unlike the free family coverage in the public system. Your monthly healthcare costs ballooned to over €1,100, and you were told you were legally barred from returning to the cheaper public system.

What To Do

  • Open your current pay slip and calculate if your monthly income is below the "Versicherungspflichtgrenze" (€5,775 in 2024).
  • Call a "Versicherungsberater" and ask for a written "Beitragsprognose" showing costs at age 65.
  • "Kann ich später wieder in die gesetzliche Versicherung zurück?" (Can I return to public insurance later?) Ask this at your first consultation with a broker.

The Truth

Germany makes it nearly impossible to leave the private system once you have reached middle age. Many expats choose PKV for short-term savings and end up trapped in high-premium cycles for life.
