Learning Objectives

  • Replacement analysis should consider only the current market value of equipment.

  • Sunk costs and past estimates are irrelevant in the replacement analysis.

  • The economic life of equipment is determined when the equivalent annual cost reaches its minimum.

Key Concepts

Economic Life

The period during which equipment is most cost-effective to operate before replacement is warranted due to increasing maintenance costs.

Sunk Cost

Costs that have already been incurred and cannot be recovered, which should not factor into current investment decisions.

Equivalent Annual Cost (EAC)

A method to convert total costs over different time periods into a uniform annual cost for comparison purposes.

Replacement Analysis

The process of deciding when to replace equipment based on economic factors, focusing on minimizing costs and maximizing efficiency.
