Like-new condition

Replacement cost, in insurance law, is the amount required to replace a damaged or destroyed property with a new, similar, and equivalent property. In building insurance, the replacement value corresponds to the amount that would be necessary to rebuild the building today with the same size and features. It forms the basis of so-called replacement value coverage-the most comprehensive form of protection in residential building insurance.

Replacement Value vs. Current Value vs. Market Value

In the insurance sector, three value concepts must be clearly distinguished from one another:

• Replacement value: Cost of new construction or new acquisition without deduction for age and wear and tear
• Current market value (also: fair market value): Replacement value minus age-related depreciation-the current condition of the building is taken into account
• Market value: The price that can be obtained on the market - dependent on location, supply, and demand, not on construction costs

Homeowners insurance policies based on replacement cost reimburse the actual repair or reconstruction costs in the event of a claim, without a “new for old” deduction. Policies based on current market value, on the other hand, reimburse only the value reduced for age - for older buildings, this difference can be significant. For a 30-year-old house, the current market value may be significantly lower than the replacement cost, resulting in a substantial shortfall in the event of a claim.

Sliding Replacement Cost in Homeowners Insurance

Since construction costs rise over time, a fixed sum insured would lose purchasing power over time. That is why modern home insurance policies generally offer a sliding replacement value: The sum insured is automatically adjusted to the construction price index. This ensures that even years later, the sum insured is still sufficient to actually rebuild the building.

The prerequisite for the waiver of underinsurance-that is, the insurer’s waiver of proportional reduction in the event of underinsurance-is generally that the originally reported sum insured was correct and the sliding replacement value mechanism is active.

The construction price index on which the sliding replacement value is based is published annually by the Federal Statistical Office. Since 2015, construction costs in Germany have risen significantly-anyone who took out their policy before 2015 and has not adjusted it may be severely underinsured. This applies particularly to older policies that are still based on the 1914 value or a fixed euro amount.

Underinsurance Risk and Its Consequences

An underestimated risk in home insurance is underinsurance: If the insured replacement value is lower than the actual replacement cost, the insurer may reduce the compensation accordingly. This risk has grown in recent years due to the massive increase in construction costs: Anyone who has not updated their policy since 2015 may be significantly underinsured.

Special caution is advised following renovations: A new roof, a new heating system, or a converted attic increase the building’s replacement value and must be reported to the insurance company. The addition of a patio, a sunroom, or a garage also increases the replacement value relevant for insurance purposes.

The consequences of underinsurance can be severe. In the event of a total loss due to fire or storm, the difference between the insurance payout and the actual reconstruction costs can quickly reach six-figure sums. Homeowners should therefore review their coverage at least every two to three years.

Practical Tip for Homeowners in Nuremberg and Franconia

We recommend that all homeowners in Nuremberg and the Franconia metropolitan region review their home insurance to ensure it provides replacement cost coverage and that the insured amount is up to date. Especially after renovations, additions, or energy-efficiency upgrades, the insured amount should be adjusted immediately-otherwise, there is a risk of significant undercompensation in the event of a claim.

A reassessment of the replacement value is particularly recommended for typical Nuremberg historic buildings from the Wilhelminian era or the 1950s that have undergone extensive renovations in recent years. We’d be happy to help you find an independent insurance advisor in the region who can review your policy objectively.

Frequently Asked Questions

What is the difference between replacement cost insurance and current market value insurance?

Replacement cost insurance covers damages based on today’s replacement or reconstruction costs-without any deduction for age or wear and tear. Current market value insurance, on the other hand, takes age-related depreciation into account, meaning that significantly less is reimbursed for older buildings or items. For residential buildings, we always recommend replacement cost coverage.

How often should I review the coverage amount of my home insurance policy?

At least every two to three years, as well as after any major construction work (renovation, addition, modernization). For policies with a sliding replacement cost and a waiver of underinsurance, the insurance company automatically adjusts this amount-but only if the original coverage amount was stated correctly.

Do I have to report renovations to the insurance company?

Yes, it is strongly recommended. Anyone who fails to report a new heating system, a converted attic, or a sunroom risks being underinsured and thus receiving reduced compensation in the event of a claim. Reporting is usually simple and free-while the premium may increase slightly, the coverage improves significantly.

How exactly is a building’s replacement value determined for insurance purposes?

The basis for the sum insured on a replacement value basis is the so-called 1914 value-a historical reference value that expresses a building’s new construction value in 1914 marks. This is extrapolated to the current value using the construction price index published annually by the Federal Statistical Office. Alternatively, insurance companies today can also calculate directly based on square meters of living space and a current construction cost rate-the so-called sliding replacement value method based on living space. When taking out a new policy, a professional valuation by an appraiser or the insurer itself is recommended to correctly determine the initial value. In the Nuremberg metropolitan region, current new construction costs for residential buildings range between 2,500 and 4,000 euros per square meter of living space, depending on the standard of finish (as of 2026). A 150 m² semi-detached house with mid-range specifications would thus have a replacement value of around 400,000 to 500,000 euros-the sum insured should be at least this amount to ensure full coverage in the event of a total loss.
