By purchasing a house, you would gain $10,858.08 (32,391.87 – 21,533.79) 
over an alternate investment at 6.25% 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 58 through 62. 
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?
