"I'm not sure we should lay out $235,000 for that automated welding machine," said Jim Alder, president of the Superior Equipment Company. That's a lot of money, and it would cost us $76,000 for software and installation, and another $38,400 per year just to maintain the thing. In addition, the manufacturer admits it would cost $39,000 more at the end of three years to replace worn-out parts." "I admit it's a lot of money," said Franci Rogers, the controller. "But you know the turnover problem we've had with the welding crew. This machine would replace six welders at a cost savings of $106,000 per year. And we would save another $6,700 per year in reduced material waste. When you figure that the automated welder would last for six years, I'm sure the return would be greater than our 15% required rate of return." "I'm still not convinced," countered Mr. Alder. "We can only get $13,000 scrap value out of our old welding equipment if we sell it now, and in six years the new machine will only be worth $22,000 for parts. But have your people work up the figures and we'll talk about them at the executive committee meeting tomorrow."
