By purchasing a house, you would gain $7,047.04 (53,095.65 – 46,048.61) over an alternate investment at 3% interest.

Deferred Annuities

Sometimes transactions are established where payments do not begin for a specified number of periods; the payments are deferred. The technique for calculating NPV may be applied assuming zero for the first cash flow. Refer to pages 73 through 77.

Example 1: You have just inherited $20,000 and wish to put some of it aside for your daughter’s college education. You estimate that when she is of college age, 9 years from now, she will need $7,000 at the beginning of each year for 4 years for college tuition and expenses. You wish to establish a fund which earns 6% annually. How much do you need to deposit in the fund today to meet your daughter’s educational expenses?

NPV.

Leases often call for periodic contractual adjustments of rental payments. For example, a 2-year lease calls for monthly payments (at the beginning of the month) of $500 per month for the first 6 months, $600 per month for the next 12 months, and $750 per month for the last 6 months. This situation illustrates what is called a “step-up” lease. A “step-down” lease is similar, except that rental payments are decreased periodically according to the lease contract. Lease payments are made at the beginning of the period.
