Deckungssumme

What Is Deckungssumme?

Deckungssumme, often referred to as the sum insured or coverage limit, represents the maximum amount an insurance company will pay out for a covered loss or claim. This fundamental concept in Versicherungsmanagement defines the financial extent of protection provided by an insurance policy to the Versicherungsnehmer. It is a critical component that sets the upper boundary for compensation in the event of a Schadensfall, encompassing various types of damages such as Sachschaden, Personenschaden, or Vermögensschaden. The Deckungssumme directly impacts the level of financial security an insured party receives, highlighting the importance of selecting an adequate limit when entering a Vertragsschluss with an Versicherer.

History and Origin

The concept of defining a maximum payout in insurance policies evolved alongside the development of modern insurance practices. Early forms of insurance, such as maritime insurance, implicitly had coverage limits based on the value of the goods or vessels insured. As insurance became more formalized and widespread, particularly with the rise of property and casualty insurance in the 17th and 18th centuries, the need for explicit limits became apparent to manage the insurer's risk exposure. For instance, the Great Fire of London in 1666 significantly impacted the development of fire insurance and underscored the importance of defined coverage.

In Germany, the legal framework for insurance, including principles of coverage, developed significantly from the late 19th and early 20th centuries. Key legislation such as the Reich Act relating to Private Insurance Undertakings (Reichsgesetz über die privaten Versicherungsunternehmungen) of 1901 and the Insurance Contract Law (Versicherungsvertragsgesetz) of 1908 established the legislative basis for private insurance and increased state influence on the insurance business. T¹², ¹³hese foundational acts laid the groundwork for standardized insurance practices, including the establishment of defined coverage limits like the Deckungssumme, which are now often subject to minimum legal requirements, especially in mandatory insurance types.

Key Takeaways

• Deckungssumme is the maximum amount an insurer will pay for a covered claim.
• It is a crucial element in assessing the financial protection offered by an insurance policy.
• The appropriate Deckungssumme varies significantly based on the type of insurance and the potential risks involved.
• Inadequate Deckungssumme can lead to significant out-of-pocket expenses for the insured in the event of a large claim.
• Regulatory bodies often set minimum Deckungssummen for certain types of mandatory insurance.

Formula and Calculation

The Deckungssumme itself is not calculated by a formula in the traditional sense, as it is a predetermined limit chosen by the Versicherungsnehmer and agreed upon with the insurer. Instead, it is a variable that influences the calculation of the Prämienberechnung. While there isn't a universal formula, the process of setting an adequate Deckungssumme often involves assessing potential maximum losses.

For instance, in liability insurance, a common approach to determining an appropriate Deckungssumme is to consider the worst-case scenario. If a policy aims to cover potential damages up to a certain euro amount (e.g., for Haftpflichtversicherung), this amount is simply the chosen Deckungssumme.

The premium (P) for a policy might be influenced by the Deckungssumme ((DS)), among other factors such as the assessed risk ((R)), the chosen Selbstbeteiligung ((SB)), and administrative costs ((C)):

[ P = f(DS, R, SB, C) ]

This function (f) is determined by the insurer based on their risk models and actuarial calculations, where a higher Deckungssumme typically results in a higher premium, assuming other factors remain constant.

Interpreting the Deckungssumme

Interpreting the Deckungssumme involves understanding its implications for financial protection. A higher Deckungssumme generally means greater protection against larger losses, but it also usually entails a higher Prämienberechnung. For individuals and businesses, the chosen Deckungssumme should realistically cover potential liabilities or losses, preventing significant financial strain in the event of a major Leistungsfall.

For example, in motor vehicle liability insurance (Kfz-Haftpflichtversicherung), German law mandates minimum Deckungssummen: 7.5 million euros for personal injury, 1.22 million euros for property damage, and 50,000 euros for pure financial losses. How¹¹ever, experts often recommend significantly higher limits, such as 50 or even 100 million euros, as severe personal injuries can quickly exceed the statutory minimums. This emphasizes that while legal minimums exist, adequate Risikomanagement often dictates opting for substantially higher coverage to truly safeguard against catastrophic events.

Hypothetical Example

Consider Anna, who owns a small graphic design agency. She is evaluating her professional Haftpflichtversicherung. She has two options for the Deckungssumme:

• Option A: 500,000 euros
• Option B: 2,000,000 euros

Anna calculates that a potential error in her design work could lead to a client losing a major advertising campaign, resulting in lost revenue and reputational damage. She estimates the maximum potential Vermögensschaden her client could claim to be around 750,000 euros.

If Anna chooses Option A with a Deckungssumme of 500,000 euros, and a claim for 750,000 euros arises, her insurance would cover only 500,000 euros. Anna would be personally liable for the remaining 250,000 euros.

However, if she selects Option B with a Deckungssumme of 2,000,000 euros, the entire 750,000 euro claim would be covered by the Versicherer, assuming it falls within the Policenbedingungen. This example illustrates how the chosen Deckungssumme directly determines the extent of financial protection and the potential out-of-pocket exposure for the insured.

Practical Applications

Deckungssumme is a core concept across various types of insurance, impacting individuals and businesses alike. In Haftpflichtversicherung, it defines the maximum compensation for damages caused to third parties, whether it's a car accident covered by Kaskoversicherung or a professional liability claim. For property insurance, the Deckungssumme often reflects the rebuilding cost of a home or the replacement value of contents. In health insurance, it might refer to the maximum amount reimbursed for medical treatments over a period or for specific procedures.

Regulatory bodies often stipulate minimum Deckungssummen for mandatory insurance types to ensure a basic level of protection for the public. For example, in Germany, the overall German insurance industry is a significant part of the economy, and statistics on its performance and activities are regularly published by entities like the Federal Statistical Office (Destatis) and the German Insurance Association (GDV), highlighting the scale and importance of insurance coverage across various sectors.

Bey⁸, ⁹, ¹⁰ond regulatory compliance, the selection of an adequate Deckungssumme is a strategic element of personal and corporate Risikomanagement, aiming to transfer sufficient financial risk to the insurer and avoid underinsurance in critical areas.

Limitations and Criticisms

While Deckungssumme provides a clear upper limit for an insurer's liability, it also presents potential limitations and criticisms, primarily concerning underinsurance. If the chosen Deckungssumme is too low, the Versicherungsnehmer may face significant out-of-pocket expenses when a claim exceeds the policy limit. This is particularly relevant in situations involving severe personal injury or extensive property damage, where costs can quickly escalate into millions.

One criticism is that insureds may not always accurately assess their true risk exposure or the potential cost of a major Schadensfall, leading them to select inadequate Deckungssummen. Furthermore, inflation and rising costs for repairs or medical care can quickly erode the adequacy of a previously sufficient Deckungssumme over time, if policies are not regularly reviewed and updated.

The issue of an "insurance gap" where significant economic losses from events like natural disasters remain uninsured, highlights a major limitation. For ⁶, ⁷instance, global economic losses from natural catastrophes can be substantial, and while the insured portion may increase, a large gap often persists, particularly in regions with less developed insurance infrastructure. This⁵ "protection gap" is a growing concern, as climate change increases the frequency and intensity of extreme weather events, leading to higher potential damages that may not be fully covered by existing policies. Some⁴ academic research suggests that widespread underinsurance after natural disasters is a persistent issue, partly due to the algorithms insurers use to estimate rebuilding costs.

², ³Deckungssumme vs. Versicherungsprämie

While closely related, Deckungssumme and Versicherungsprämie refer to distinct components of an insurance contract.

Confusion often arises because these two terms are intertwined in the decision-making process for an insurance policy. A policyholder selects a desired Deckungssumme, and this choice, among other factors, directly influences the calculated Versicherungsprämie they must pay. Essentially, the premium is the price for the financial protection, the upper limit of which is the Deckungssumme.

FAQs

What happens if the damage exceeds the Deckungssumme?

If the total cost of a Schadensfall exceeds the agreed-upon Deckungssumme, the Versicherer will only pay up to the Deckungssumme. The remaining costs must be covered by the Versicherungsnehmer out of their own pocket. This is why selecting an adequate Deckungssumme is crucial for comprehensive financial protection.

Is the Deckungssumme legally mandated?

For certain types of insurance, such as motor vehicle Haftpflichtversicherung, there are legally mandated minimum Deckungssummen. These minimums ensure a basic level of protection for third parties. For other insurance types, like home contents insurance, the Deckungssumme is typically chosen by the policyholder based on their estimated value of insured items.

How often¹ should the Deckungssumme be reviewed?

It is advisable to review the Deckungssumme regularly, ideally annually or whenever significant life events occur (e.g., purchasing new valuable assets, significant property renovations, or changes in professional responsibilities). This ensures that the coverage remains adequate in light of inflation, increasing costs, and evolving personal or business needs. Regular review helps prevent Unterversicherung, where the insured amount is insufficient to cover potential losses.

Can I increase my Deckungssumme after Vertragsschluss?

In many cases, it is possible to increase your Deckungssumme after the initial Vertragsschluss. This often requires an adjustment to your policy, which may lead to a higher Versicherungsprämie. Contacting your Versicherer is the best way to explore your options for adjusting coverage limits.

What is the difference between Deckungssumme and Selbstbeteiligung?

The Deckungssumme is the maximum amount the insurer pays, while Selbstbeteiligung (deductible) is the amount the insured must pay out-of-pocket for each claim before the insurer's coverage begins. For example, if you have a Deckungssumme of €1,000,000 and a Selbstbeteiligung of €500, for a €10,000 claim, you would pay €500 and the insurer would pay €9,500, up to the €1,000,000 limit.
