20. Equivalent Annual Cost Calculation

The chapter focuses on the calculation of Equivalent Annual Costs (EAC) associated with operating and maintenance costs, salvage value, and purchase price of equipment. It provides step-by-step methodologies to convert various future cash flows into present values, ultimately assisting in the economic life analysis of machinery. The tracking of costs throughout the machine's lifecycle helps determine optimal replacement timings.

Learning Objectives

  • Understanding of Equivalent Annual Cost (EAC) and its significance in cost analysis.

  • Methods for calculating present worth using present worth factors and uniform series capital recovery factors.

  • The importance of economic life analysis and optimum replacement timing for machinery.

Key Concepts

Equivalent Annual Cost (EAC)

A cost measure that equates different costs to a uniform annual payment, allowing for better comparisons over time.

Present Worth Factor

A factor used to convert future costs into their present value at a specific interest rate.

Uniform Series Capital Recovery Factor

A factor that converts a present sum into a series of equal annual payments (EAC) over time at a given interest rate.

Economic life of a machine

The period during which a machine is economically efficient to operate, often determined when costs are minimized.

Sunk Cost

A cost that has already been incurred and cannot be recovered; irrelevant in decision-making for replacement analysis.
