A farmer near Bloomington owns a combine and uses it to provide harvesting service to other farmers. He receives revenue of $40,000 a year, plus the avoidance of $2,000 in fees he would have to pay someone else to harvest his wheat if he did not own the machine. Fuel and repairs are $10,000 a year, and the farmer does not have another profitable use for the time he spends harvesting wheat. Unfortunately, the existing combine is worn out and fully depreciated. It can be sold for its $1,000 spare parts value, but a dealer will allow $5,000 as a trade-in allowance on a new $100,000 combine. The new combine will last for an estimated 10 years (depreciated with a 7year MACRS technique), after which it will have a negligible salvage value. The farmer is in a 28% tax bracket and requires a 10% return on investments. Is the new combine an attractive investment?
