Remarks:
The TVM equation requires that I must be non–zero to avoid a
#
&
error. If you're solving for I and aren't sure of its current value, press 1
H
I before you begin the SOLVE calculation (
{
I ).
The order in which you're prompted for values depends upon the variable
you're solving for.
SOLVE instructions:
1. If your first TVM calculation is to solve for interest rate, I, press 1
H
I.
2. Press
{
G
. If necessary, press
z
or
z
to scroll
through the equation list until you come to the TVM equation.
3. Do one of the following five operations:
a. Press
{
N to calculate the number of compounding
periods.
b. Press
{
I to calculate periodic interest.
For monthly payments, the result returned for I is the monthly interest
rate, i; press 12
y
to see the annual interest rate.
c. Press
{
B to calculate initial balance of a loan or savings
account.
d. Press
{
P to calculate periodic payment.
e. Press
{
F to calculate future value or balance of a
loan.
4. Key in the values of the four known variables as they are prompted for;
press
f
after each value.
5. When you press the last
f
, the value of the unknown variable is
calculated and displayed.
6. To calculate a new variable, or recalculate the carne variable using
different data, go back to step 2.
SOLVE works effectively in this application without initial guesses.
