Effective Age
An assessment of the age of an asset relative to the condition of the asset and how that condition may have accelerated (or decelerated) the chronological age of the asset.

Used primarily in the computations or remaining useful life in a reserve study.

Some of the key factors impact the effective age of an asset:

There are three general scenarios governing effective age:
  • Higher:  If the effective age is higher than the chronological age, then the asset is suffering from premature ageing.
  • Same:  If the effective age is the same as the chronological age, then the condition of the asset is consistent with its age.
  • Lower:  If the effective age is lower than the chronological age, then the asset is underutilized.
Light traffic will result in an effective age being lower than chronological age.
