Introduction
Thank you for purchasing a SHARP Financial Calculator.
After reading this manual, store it in a convenient location for
future reference.
• Display of examples shown in this manual may not look ex-
actly the same as what is seen on the product. For instance,
screen examples will show only the symbols necessary for
explanation of each particular calculation.
• All company and/or product names are trademarks and/or
registered trademarks of their respective holders.
• Some of the models described in this manual may not be
available in some countries.
Operational Notes
• Do not carry the calculator around in your back pocket, as it
may break when you sit down. The display is made of glass
and is particularly fragile.
• Keep the calculator away from extreme heat such as on a car
dashboard or near a heater, and avoid exposing it to exces-
sively humid or dusty environments.
•
Since this product is not waterproof, do not use it or store it where
fluids, for example water, can splash onto it. Raindrops, water spray,
juice, coffee, steam, perspiration, etc. will also cause malfunction.
• Clean with a soft, dry cloth. Do not use solvents or a wet cloth. Avoid
using a rough cloth or anything else that may cause scratches.
• Do not drop the calculator or apply excessive force.
• Never dispose of batteries in a fire.
• Keep batteries out of the reach of children.
• This product, including accessories, may change due to up-
grading without prior notice.

Getting Started
Preparing to Use the Calculator
Before using your calculator for the first time, you must reset
(initialize) it.
Resetting the calculator
Press the RESET switch located on the
back of the calculator with the tip of a
ball-point pen or similar object. Do not
use an object with a breakable or sharp
tip.
• After resetting the calculator,
the initial display of the NOR-
MAL mode appears.
Resetting the Calculator In Case of Difficulty
Caution:
The RESET operation will erase all data stored in
memory and restore the calculator’sdefault setting.
In rare cases, all the keys may cease to function if the calculator
is subjected to strong electrical noise or heavy shock during use.
If pressing any of the keys (including s) has no effect, reset
the calculator.
Resetting the calculator
See the above procedure.
Note: Pressing .kand 1=will also erase all
data stored in memory and restore the calculator’s default
setting.

Selecting the display notation and number of decimal
places
The calculator has three display notation systems (fixed decimal
point, scientific notation and floating point) for displaying calcu-
lation results.
• If
~00(TAB) is pressed, “DIG(0-9)?” will be
displayed and the number of decimal places can be set to any
value between 0 and 9.
• If
~01(SCI) is pressed, “SIG(0-9)?” will be dis-
played and the number of significant digit can be set to any
value between 0 and 9. Entering 0 will set a 10-digit display.
• If a floating point number does not fit in the specified range,
the calculator will display the result in scientific notation (expo-
nential notation). See the next section for details.
• The default setting is a fixed decimal point with two decimal
places.

Selecting the floating point number system in scien-
tific notation

sgand then specify the memory.
• To clear or restore to the default setting one variable or value
of TVM variables, listed financial variables, cash flow data, or
STAT, r e fe r t o th e re l e v a n t section.
• If you turn off the calculator (by pressing .cor by let-
ting it turn itself off automatically), it will resume wherever you
left off when you turn it on again.
Delete key

Memory Calculations
This calculator has 11 temporary memories (A-H and X-Z), one
independent memory (M) and one last answer memory (ANS).
It also has various variables for use in financial calculations and
statistical calculations.

Temporary memories(A-H, X-Z)
Press gand the variable key to store a value in memory.
Press fand the variable key to recall a value from the
memory.
To place a variable in an equation, press iand the variable key.
Independent memory (M)
In addition to all the other features of temporary memories, a
value can be added to or subtracted from an existing memory
value.
Press sgMto clear the independent memory (M).
Last answer memory (ANS)
• The calculation result obtained by pressing =or any other
calculation ending instruction (including storing and recalling
operations) is automatically stored in the last answer memory.
• Listed financial variables are automatically stored in the last
answer memory by displaying the variable and the value.
TVM variables
TVM variables can be recalled using fin the same way as
temporary memories. It is not necessary to press gto store
a value.
Listed financial variables
Financial variables are specific to the type of calculation they
are used in. For example, the variable N is available to the TVM
solver but not to discounted cash flow analysis calculations. If
you want to carry a value from a variable over into a different
type of calculation, use one of the following methods:
•
Last answer memory (ANS): Within the original calculation, dis-
play the variable and value that you wish to carry over.The value
is automatically entered into last answer memory. Press sto
exit the calculation (the listed financial variables will disappear
from the screen), and press i/to bring up the value
from the previous calculation. M-D-Y (D-M-Y) 1 and M-D-Y (D-
M-Y) 2 are not stored in last answer memory.
• Variables common to both calculations: If the value that you
wish to carry over is held in a variable that exists in both types

16
of calculation (for example, both bond calculations and the TVM
solver use the variable I/Y), you can retrieve the value simply by
switching calculation types and bringing up the variable.
Statistical variables
Statistical data is not entered into variables. Statistical variables
are the results of the calculation of statistical data. Therefore,
you cannot enter values directly into statistical variables. After
calculation, however, you can use the values held in statistical
variables in subsequent calculations.
Note: Use of
for iwill recall the value stored in
memory using up to 14 digits.

Financial Functions
General Information
Financial calculations
The following financial functions are available. Use NORMAL
mode to perform financial calculations.
TVM (Time Value of Money) solver: Analyze equal and regular
cash flows. These include calculations for mortgages, loans,
leases, savings, annuities and contracts or investments with
regular payments.
Amortization calculations: Calculate and create amortization
schedules using values stored in the TVM solver.
Discounted cash flow analysis: Analyze unequal cash flows
and calculate NPV (net present value) and IRR (internal rate of
return).
Bond calculations: Solve bond prices or yields to maturity with
accrued interest.
Depreciation calculations: Obtain depreciation base values
using three types of calculation methods.
Conversion between APR and EFF: Interest rates can be con-
verted between APR (annual, or nominal percentage rate) and
EFF (effective interest rate).
Day and date calculations: Calculate dates and the number of
days between dates.
Percent change/Compound interest calculations: Calculate
percent change (increase or decrease) and compound interest
rates.
Cost/Sell/Margin/Markup calculations: Calculate cost, selling
price and margin/markup.
Breakeven calculations: Calculate breakeven points (quantity)
using fixed costs, variable costs per unit, unit prices, and profit.

18
Variables used in financial calculations
Financial calculations use multiple variables. By entering known
values into variables, you can obtain unknown values. Variables
used in financial calculations are categorized into the following
two types, depending on the entry method.
TVM variables:
Variables that are used in the TVM solver. These include N,
I/Y, PV, PMT and FV. You can store, recall or calculate values
directly using the corresponding keys.
Listed financial variables:
Variables that are organized into lists in different categories. These
variables can be accessed using the z/icursor keys in
each calculation. P/Y and C/Y in the TVM solver are of this type of
variable.
Variables shared among calculations
Financial variables are specific to the type of calculation they
are used in. Values are stored in these variables and recalled
as required. Some variables are shared (in the memory area)
among calculations. If you change the value of a variable in one
calculation, the value will change in all the other calculations
as well. The following list shows the variables shared between
calculations. While calculating, be aware of the values stored in
these variables.
