It is not necessary to reenter TVM values for each example. Using the
values from the previous page, how much can you borrow if you want
a payment of $100.00?
100FP
± Enters new payment
amount. (Money paid out is
negative.)
$    Calculates amount you can
borrow.
How much can you borrow at a 9.5% interest rate?
9.5L  Enters new interest rate.
$
   Calculates new present
value for $100.00 payment
and 9.5% interest.
10L  Reenters original interest
rate.
14000$   Reenters original present
value.
P
± Calculates original
payment.

Find the annual effective interest rate of 10% nominal interest
compounded monthly.
10H&  Enters nominal rate.
12H¢
 Enters payments per year.
Hx
 Calculates annual effective interest.
H¢ Number of periods per year (default is 12).
J
Cash flows, up to 15 ( j is the cash flow number).
Ha
Number of consecutive times cash flow j occurs.
HW
Internal rate of return per year.
Hl Net present value.

After calculating a payment using Time Value of Money (TVM), enter
the periods to amortize and press H! . Then press = to continually
cycle through the interest, principal, and balance values (indicated by
the , , and annunciators respectively).
Using the TVM example from the previous page, amortize a single
payment and then a range of payments.
th
Amortize the 20 payment of the loan.
20N 
Enters period to amortize.
H!  ±  Displays period to
amortize.
= ± Displays principal.
=
± Displays interest. (Money
paid out is negative.)
=   Displays balance.

If you have an initial cash outflow of $40,000, followed by monthly
cash inflows of $4,700, $7,000, $7,000, and $23,000, what is the IRR/
YR? What is the IRR per month?
HD 
Clears all memory.
12H¢  Sets payments per year.
40000FJ ± 
Enters initial outflow.
4700J
  Enters first cash flow.
7000J  
Enters second cash flow.
2Ha  Enters number of consecu-
tive times cash flow occurs.
23000J   Enters third cash flow.
HW
  Calculates IRR/YR.
¤12=  Calculates IRR per month.
What is the NPV if the discount rate is 10%?
10L  Enters I/YR.
Hl
 Calculates NPV.

st th
Amortize the 1 through 12 loan payments.
1N12 B
Enters range of periods to amortize.
H!
 ±  Displays range of payments.
=
± Displays principal.
=
±   Displays interest.
  Displays balance.
=
To convert between nominal and effective interest rates, enter the
known rate and the number of periods per year, then solve for the
unknown rate.
H& Nominal interest percent.
Hx
Effective interest percent.
H¢ Periods per year.
