Your boss, a real estate business manager, has approached you for financial advice. She is interested in either purchasing or leasing a new car for her personal use. Aware of your financial expertise, she has asked you to develop a Spreadsheet Model that allows her to decide whether to buy or lease the vehicle.

The retail price of the car she is interested in is $50,000.

Buy Scenario

In the Buy Scenario, your boss would like to purchase the car by making an initial down payment of $15,000 dollars and finance the difference with a conventional car loan to be repaid monthly for 3-years at a 5% interest rate. The following table summarises the relevant information for the Buy Scenario.

Buy Scenario

Car Price $ 50,000.00

Down Payment $ 15,000.00

Interest Rate 5%

Term 3 years

Lease Scenario

In the Lease Scenario, there is no initial down payment. Instead, your boss would like to use a Finance Lease to rent the car for 3 years. At the end of this 3-year period, she plans to purchase the car from the lease financier (lessor) by paying a residual value of $25,000. In this scenario, to rent the car, your boss would have to pay a monthly rent of $850 for 3 years. The following table summarises the relevant information for the Lease Scenario.

Lease Scenario

Car Price $ 50,000.00

Residual Value $ 25,000.00

Monthly Rent $850

Term 3 years
