How to Calculate the Right Sum Insured for Your Family in Germany

When planning the financial security of your family in Germany, choosing the right sum insured is one of the most crucial decisions you can make. This figure not only defines the payout your family will receive in the event of your death but also determines your monthly or annual premium. 

Surprisingly, many German residents and expats either underinsure or overinsure their families, simply because they don’t understand how to calculate this value accurately.

As a licensed insurance broker with 10 years of experience in Germany and 3 years in Switzerland, I’ve helped hundreds of families understand this decision. Based on my professional insights, this guide explains how to determine the right sum insured in Germany, what factors influence your calculations, and why it’s essential to get it right.

Why the Right Sum Insured Matters in Germany

The sum insured (Versicherungssumme) is the amount your insurer agrees to pay out in the event of a claim. In the context of life insurance, it’s the amount your beneficiaries receive after your death. If this amount is too low, your family might struggle to maintain their lifestyle or cover essential expenses. If it’s too high, you might be paying unnecessarily high premiums.

Germany’s Federal Financial Supervisory Authority (BaFin) encourages consumers to review their policies regularly, especially after major life events like marriage, childbirth, or purchasing property.

Step-by-Step: How to Calculate the Right Sum Insured

There is no universal formula, but you can use the following approach for a close estimate:

1. Calculate Ongoing Living Expenses: Start by estimating your family’s monthly living expenses. This should include:

• Rent or mortgage payments
• Utilities and maintenance
• Food and groceries
• Transportation
• Education costs
• Health insurance and medical expenses

Multiply this monthly amount by the number of years you want your life insurance to support your family, typically between 10 and 20 years. For example, if your family’s monthly cost of living is €2,500 and you want coverage for 15 years, that’s €450,000.

2. Factor in One-Time Expenses: Add expenses your family would face only once, such as:

• Funeral costs (€5,000 to €10,000 in Germany)
• Outstanding debts (e.g., credit card loans, personal loans)
• University tuition for children

3. Subtract Existing Assets: If your family already has savings, investments, or a paid-off home, subtract these from your required sum. This helps avoid overinsuring.
4. Account for Inflation: Inflation in Germany currently hovers around 2.5% (as of 2025). Over 15 to 20 years, this can significantly reduce the value of money. Use a compound interest calculator or speak with a broker to add a buffer for inflation.
5. Include Income Replacement: Many people forget that their income will be lost if they pass away. Multiply your net annual income by the number of years your family would need support. A commonly used range is 5 to 10 years.

Sample Calculation for a Family in Munich

Let’s consider a 38-year-old man with two children and a non-working spouse. His net income is €3,000 per month. He wants his family to be supported for 15 years.

• Living expenses: €3,000/month x 12 x 15 = €540,000
• One-time costs: €50,000
• Income replacement: €3,000/month x 12 x 10 = €360,000
• Existing savings: €100,000
• Total required: €850,000

In this case, the right sum insured for his family based in Germany would be around €850,000.

Common Mistakes to Avoid When Calculating the Right Sum Insured

Many families in Germany fall into traps when choosing their coverage:

• Underestimating Future Needs: Families often forget to include education costs or future rent increases.
• Ignoring Inflation: Over 10 to 20 years, inflation can erode value.
• Not Updating the Policy: A policy bought before kids or homeownership might be outdated.

Best Practices When Choosing a Sum Insured in Germany

• Review Annually: Update your coverage as your family grows or your income changes.
• Use Online Calculators: Tools from Allianz, HUK-COBURG, or CosmosDirekt can help estimate your needs.
• Work with a Broker: A broker can ensure you balance cost and coverage efficiently.
• Look for Flexibility: Choose policies that allow you to increase the sum insured without a new health exam.
