Because the calculator stores values assigned to the TVM variables until

you clear or change them, you should not have to perform all steps each

time you work a problem.

• To assign a value to a TVM variable, key in a number and press a TVM

key (,, -, ., /, 0).

• To change the number of payments (P/Y), press &[, key in a

number, and press !. To change the compounding periods (C/Y),

press &[ #, key in a number, and press !.

• To change the payment period (END/BGN), press & ], and then

press & V.

• To compute a value for the unknown variable, press %, and then

press the key for the unknown variable.

Variable Key Display Type of Variable

Number of periods , N Enter-or-compute

Interest rate per year - I/Y Enter-or-compute

Present value . PV Enter-or-compute

Payment / PMT Enter-or-compute

Starting payment & \ P1 Enter-only

Ending payment # P2 Enter-only

Balance # BAL Auto-compute

Principal paid # PRN Auto-compute

Interest paid # INT Auto-compute

• To generate an amortization schedule, press & \, enter the

first and last payment number in the range (P1 and P2), and press "

or # to compute values for each variable (BAL, PRN, and INT).

Resetting the TVM and Amortization Worksheet Variables

• To reset all calculator variables and formats to default values

(including TVM and amortization variables), press & } !:

• To reset only the TVM variables (N, I/Y, PV, PMT, FV) to default values,

press & ^.

• To reset P/Y and C/Y to default values, press & [ & z.

• To reset the Amortization worksheet variables (P1, P2, BAL, PRN,

INT) to default values, press & z while in the Amortization

worksheet.

• To reset END/BGN to the default value, press & ] & z.

Clearing the Unused Variable

For problems using only four of the five TVM variables, enter a value of

zero for the unused variable.

For example, to determine the present value (PV) of a known future

value (FV) with a known interest rate (I/Y) and no payments, enter 0 and

press PMT.

Entering Positive and Negative Values for Outflows and

Inflows

Enter negative values for outflows (cash paid out) and positive values for

inflows (cash received).

Note: To enter a negative value, press S after entering the number. To

change a negative value to positive, press S.

Variable Default Variable Default

N 0 END/BGN END

I/Y 0 P1 1

PV 0 P2 1

PMT 0 BAL 0

FV 0 PRN 0

P/Y 1 INT 0

C/Y 1

Entering Values for I/Y, P/Y, and C/Y

• Enter I/Y as the nominal interest rate. The TVM worksheet

automatically converts I/Y to a per period rate based on the values of

P/Y and C/Y.

• Entering a value for P/Y automatically enters the same value for C/Y.

(You can change C/Y.)

Specifying Payments Due With Annuities

Use END/BGN to specify whether the transaction is an ordinary annuity

or an annuity due.

• Set END for ordinary annuities, in which payments occur at the end

of each payment period. (This category includes most loans.)

• Set BGN for annuities due, in which payments occur at the beginning

of each payment period. (This category includes most leases.)

Note: When you select beginning-of-period payments, the BGN indicator

appears. (No indicator appears for END payments.)

Updating P1 and P2

To update P1 and P2 for a next range of payments, press % with P1 or

P2 displayed.
