The minimum coverage defined by German law for car liability insurance / third party personal insurance is €7,500,000 for bodily injury (damage to people), €500,000 euro for property damage and €50,000 for financial/fortune loss which is in no direct or indirect coherence with bodily injury or property damage. Insurance companies usually offer all-in/combined single limit insurances of €50,000,000 or €100,000,000 (about €141,000,000) for bodily injury, property damage and other financial/fortune loss (usually with a bodily injury coverage limitation of €8-15,000,000 for each bodily injured person).
When the premium is not mandated by the government, it is usually derived from the calculations of an actuary, based on statistical data. The premium can vary depending on many factors that are believed to affect the expected cost of future claims. Those factors can include the car characteristics, the coverage selected (deductible, limit, covered perils), the profile of the driver (age, gender, driving history) and the usage of the car (commute to work or not, predicted annual distance driven).
