Question

Granny's Butter and Egg Business is such that she pays an effective tax rate of 40%. Granny is considering the purchase of a new Throb Churn for $25,000. This churn is a special handling device for food manufacture and has an estimated life of 4 years and a salvage value of $5000. The new churn is expected to increase net income by $8000 per year for each of the 4 years of use. If Granny works with an after-tax MARR of 10% and uses MACRS depreciation, should she buy the churn?

Note: the correst answer is AT NPW = $587. so please show me a step-by-step solution on how to get that. Thanks!

Explanation / Answer

Hi,

Please find the detailed answer as follows:

Step 1: Calculate Annual Cash Inflows (You need to Use MACRS 4 Year Table)

Step 2: Calculate NPW

NPW = -25000 + 8133/(1+.10)^1 + 9245/(1+.10)^2 + 6281/(1+.10)^3 + 5541/(1+.10)^4 + 5000*(1-.40)/(1+.10)^4 = 586.75 or 587

Answer is 587.
