The Cost Method estimates the replacement value of a property by analyzing the cost component of the specific land and building. It lies somewhere between the inferred and the intrinsic methods, and is not a fully autonomous valuation method.

Value is calculated by adding the free market value of the land as if vacant to the reconstruction cost of the building, minus depreciation suffered over the years in comparison to a new building.

Procedure
- Estimate the value of the land as if vacant, by comparing it to similar properties.
- Estimate the replacement cost of the building at present. Factors to be considered include site preparation, utilities, types of building improvements, tenant improvements, and soft costs.
- Assess the depreciation that has occurred to the building and deduct the figure from the replacement cost new.
- Add the estimated worth of the land. The resulting figure will be an indication of the value of the property.

Example:

Market value of land: RM100,000

Replacement cost of the building: RM500,000

Depreciation: RM75,000

Value of property: RM525,000


Advantages and Disadvantages
+ Sets the value at the actual cost or price of the property.
- Relies upon other valuation methods to derive the value of the land.
- Neglects the difference between cost and value, namely that one property might be cheaper than another but generate a much higher net income.
