German Health Insurance Test Reveals Wide Gaps in Premiums and Service – Savings of Up to €660 Possible

Health insurance holders in Germany can pocket hundreds of euros a year simply by switching to a cheaper provider, according to a new comparison by Stiftung Warentest published this week. The consumer watchdog analysed 67 statutory health insurers and found contribution rates ranging from 16.78 percent to 18.99 percent of gross income. For someone earning €3,000 a month, moving to the cheapest plan saves up to €340 annually; for high earners at the contribution assessment ceiling, the figure reaches €660.
The survey coincides with a quality test by the German Institute for Service Quality (DISQ), which rated 21 public health insurers between January and May. Six earned “very good,” ten “good,” and five only “satisfactory” or “adequate.” Viactiv took the top spot overall, praised for its naturopathic treatments and online service. Runner-up was AOK Rheinland-Pfalz/Saarland, which not only ranked second but also charged the lowest supplemental premium among all tested plans – 2.47 percent – and offered bonuses of up to €250. Third place went to AOK Bayern.
Supplementary benefits vary widely. Seventeen of the 21 insurers fully reimburse prevention courses, 19 cover flu shots completely, and every provider runs a bonus programme with cash rewards as high as €275.
But service remains a weak point. One in five phone calls to the hotlines went unanswered. Those who got through waited an average of two minutes on hold. In a separate customer-service survey by ServiceValue, the Debeka stood out for strong advice quality in health and long-term care.
Despite the cost pressures, many low-premium insurers have kept or even expanded their extra services. Policyholders can switch after a 12-month minimum membership period, and anytime a plan raises its premium, a special cancellation right applies with a two-month notice period.
Behind the good news for consumers, however, dark warnings are emerging. Oliver Blatt of the National Association of Statutory Health Insurance Funds (GKV-Spitzenverband) sounded the alarm over exploding costs. In the first quarter of 2026, spending jumped eight percent. Hospitals surged 9.4 percent, physician services 7.3 percent, and pharmaceuticals 6.4 percent.
For 2027, a financing gap of roughly €18.8 billion is projected. The federal cabinet’s draft budget covers only €16.3 billion, according to the association. The funds are demanding higher federal subsidies and a greater share from the pharmaceutical industry. Their target: lower the average supplemental premium from 3.1 percent to 2.9 percent. The legislative package is scheduled for passage by mid-July.
