Emaar Builders need to acquire the use of a crane for construction business, and are considering buying or leasing a crane. The crane costs Rs. 2,500,000, and is subject to the straight-line method of depreciation to a zero-salvage value at the end of 5 years. In contrast, the lease rent is Rs 550,000 per year to be paid in advance each year for 5 years. Emaar Builders can raise debt at 18% payable in equal annual instalments, each instalment due at the beginning of the year. The company is in the 30% tax bracket. Should it lease or buy the crane?
