Meaning
Valuation techniques estimate the total expenditure required to replicate the functionality and architecture of an existing software system from the beginning. A replacement cost analysis provides a floor for the value of a codebase by summing the labor, infrastructure, hardware and overhead expenses needed for a rebuild. It focuses on the current prices of inputs.
Labor Calculation
Engineering hours represent the largest component of the final figure. The replacement cost analysis counts the number of developer months required to write, test and deploy the logic. It uses current market salaries for specialized roles to ensure the estimate is up to date.
Architecture Modernization
Modernizing the architecture during a hypothetical rebuild can alter the valuation. A replacement cost analysis might subtract the value of obsolete components or inefficient code structures. This ensures the result reflects the cost of a modern equivalent.
Historical costs are not used for this calculation.
Floor Valuation
Founders use this method when market comparisons are unavailable or when the software does not yet generate revenue. The replacement cost analysis is a secondary check against other valuation methods. It stops being the primary metric once the software enters a high-growth phase where utility outweighs the cost of creation.
