Now you can press 6 to draw a cash flow graph.
6 (GRPH)
The left side is PV , while the right side is FV . The upper part of the graph is
positive (+), while the bottom part is negative (–).
u u u u u Installment savings
Input Condition: Future value is greater than the total of payments.
Formula Representation of Input Condition:
PMT and FV have different signs (positive, negative) when PV = 0.
– FV < n × PMT when FV > 0
– FV > n × PMT when FV < 0
Example Calculate the interest rate required to have a $2,500 balance in
an installment savings account in two years when $100 is
deposited each month and interest is compounded semiannu-
ally.
Perform the following key operations from the input screen.
c*bcw (Input n = 2 × 12.)

aw ( PV = 0)
- baaw ( PMT = –100)
cfaaw ( FV = 2,500)
bcw (Monthly installment)
cw (Compounding every six months)

Loans
Input Condition: Total of payments is greater than loan amount.
Formula Representation of Input Condition:
PMT and PV have different signs (positive, negative) when FV = 0.
– PV > n × PMT when PV > 0
– PV < n × PMT when PV < 0
