## TI BA II Information

The newer TI BA II Plus is not identical. It is far superior to the older TI BA II, and in fact, if you have an older TI BA II, we strongly recommend that you obtain a newer financial calculator.
Financial Keys
N, number of periods
%i, rate of interest per period
PMT, payment per period
PV, present value
FV, future value
Conventions
Payments are always positive numbers.
Future values are balances, usually entered as positive numbers.
At least one of PMT, PV, and FV must be zero.

Floating Decimal
Press FIX 9.
Financial Mode
Press 2nd MODE until FIN appears in the display.
Clearing Financial Data
Press 2nd CMR.
Beginning Annuities
Substitute the DUE key for the 2nd key at the time you compute the missing value.

Entering Financial Data
Display the value, then press the financial key.
Computing Values
Press 2nd, followed by the financial key to be computed.

Example:
Tom's account begins with \$500, and earns 6% per year, compounded monthly. He deposits an additional \$50 at the end of each month. What will the balance be at the end of one year?

The variables are:
 N = 12 I = 6/12 PMT = 50 increasing PV = 500 FV = ???

The keystrokes are:
2nd CMR
12 N
0.5 %i
0 PMT
500 PV
2nd FV
The first intermediate answer of \$530.84 is noted.
Then we enter the following:
2nd CMR
12 N
0.5 %i
50 PMT
0 PV
2nd FV

The second intermediate answer is \$616.78. This is added to the first intermediate answer to produce the final answer, \$1,147.62, rounded to the nearest cent.
