An injection molding system has a first cost of $180,000, and an annual operating cost of $84,000 in years 1 and 2, increasing by $5000 per year thereafter:= $−246,000.
Operating expenses are operating expenses incurred in the course of a business's day-to-day activities. Operating expenses include both cost of goods sold (COGS) and other operating expenses, often referred to as selling, general, and administrative (SG&A) expenses.
a) Determine the ESL and the respective AW value of the system by hand solution:
\begin{align*} \text{AW}_1&=-180{,}000(A/P, 15\%, 1)-84{,}000+45{,}000(A/F, 15\%, 1)\\[7pt] &=-180{,}000(1.1500)-84{,}000+45{,}000(1.0000)\\[7pt] &= \boxed{\$-246{,}000}\\ \end{align*}
AW 1
=−180,000(A/P,15%,1)−84,000+45,000(A/F,15%,1)
=−180,000(1.1500)−84,000+45,000(1.0000)
= $−246,000.
