Is there a quick way to do Question 19 on page 342 Reading 6: Time Value of Money on the ba ii plus (as opposed to typing all those numbers in and compounding)? And how would you do it? Thanks in advance.

I don’t have access to the LI materials. Can you describe the problem generally?

It depends on what qualifies as *quick* to you.

The straightforward, relatively quick calculation is:

((4,000(1.02)^{2} + 8,000)(1.02)^{2} + 7,000)(1.02)^{2} + 10,000

Alternatively, you can put in these cash flows:

0, 4000, 0, 8000, 0, 7000, 0, 10000

Compute NPV with *i* = 2%. Using that value as PV, compute the FV after 8 periods.

You can also use the TVM worksheet to calculate the FV of each individual deposit:

2nd CLR TVM

P/Y=C/Y=1, PMT=0 for all payments

For the first deposit:

6 N, 2 I, PV=-4000 CPT FV 4,504.6496

Repeat for all other deposits, changing N and PV as appropriate. You can store the FVs in memory and sum them up.

It’s not very quick, but saves you the time of doing the compounding.
