The cost of the new machine is $$127,000.$

Installation will cost $$20,000.$

$$4,000$ in net working capital will be needed at the time of installation.

The project will increase revenues by $$85,000$ per year, but operating costs will increase by $35\%$ of the revenue increase.

Simplified straight line depreciation is used.

Class life is $5$ years, and the firm is planning to keep the project for $5$ years.

Salvage value at the end of year $5$ will be $$50,000.$

$14\%$ cost of capital; $34\%$ marginal tax rate. $///////$ The depreciation is $29400.$ How do I get this result? Could you please show me how to get depreciation by NOT using excel but calculation?
