What is another name for the economic age-life method of measuring depreciation?

The economic age-life method of measuring depreciation is often referred to as the age-life method. This approach estimates the depreciation based on the age of the property in relation to its expected lifespan. By comparing the effective age, which reflects the property's condition and upkeep, with the total economic life, the appraiser can determine the amount of depreciation that has occurred.

Using this method, appraisers assess how much value has been lost due to factors such as wear and tear, physical deterioration, and functional obsolescence. The simplicity and effectiveness of this method make it a popular choice among appraisers for determining depreciation in the valuation process.

While other terms mentioned, such as capitalized value, market extraction, and observed condition, relate to different valuation techniques or approaches in appraisal, they do not specifically refer to this method of measuring depreciation. This distinguishes the age-life method as the most accurate term for the approach in question.
