BAII Plus TVM Applications

Make sure you have P/Y set to 1 and BGN/END set to END. With those settings, pressing 9 I/Y 9 2 0 FV 1 0 0 +/- PMT CPT N should produce 7.00 .

For a thirty-year, $100,000 mortgage at 8% annually, compute the monthly payment:

2nd [CLR TVM] ( clear the time value of money registers )
3 0 * 1 2 N ( thirty years at twelve payments per year )
8 I/Y ( 8% annual interest )
1 0 0 0 0 0 PV ( $100,000 mortgage )
CPT PMT ( compute payment )

You should see -733.76. The negative indicates payment, the amount is $733.76.

GOOD QUESTION, Patweetyp...

I've got you covered.

Seeing how it's been three weeks since you posted this there's a chance you've already gotten your answer, but let me go ahead solve this for those out there who may have had the same problem.

Background: There are FIVE TVM Keys; and as you would assume, you MUST input FOUR of them in order for the BA II Plus to solve for the fifth. Now let's get down to business.

1. Hit CLR TVM. [This is just a cleanup maneuver]
1a. Hit ENTER [yes, BA II Plus always needs to be told to store the value, ALWAYS]
2. Type in -2400
3. Hit PV [Since you are investing money at time 0, your present value is negative 2400]
3a. Hit ENTER
4. Type 6
5. Hit I/Y [Your annually compounded interest rate is 6 percent]
5a. Hit ENTER
6. Type 0
7. Hit PMT [you do not have any recurring deposits*]
7a. Hit ENTER
8. Type 1
9. Hit N [there is one year until expiration/liquidation/termination]
9a. Hit ENTER
10. Hit CPT
11. Hit FV [this is your ANSWER = 2544]
----- From here, all you would need to do is change N in order to get your other answers (5 years, 10 years, etc) ----

*If your calculation does not require a recurring payment then you really just have a basic equation of value which would be solved faster by hand. (IE, 2400*(1.06)^1=FV=2544).

You'll notice that I underlined "annually compounded" as well as "one year". The reason for this is because you ALWAYS need your interest term to match your time interval. For instance, if you had monthly payments of which you wanted the year-end total you would need a monthly effective interest rate, and N would be 12.



Okay, I hope that helped. The BAII Plus is the best calculator for time-value-money calculations I've come across. When things get more advanced, you will start using the amortization table which cannot be found in any other TI Calculator (from what I know). TVM is perfect for annuities, mortgages, loans, bonds, and more.

TEXAS INSTRUMENTS = 1-800-TI-CARES...they are friendly.

Use the (-) key to the right of the decimal point key instead of the - key to the right of the 6 key to enter negative values.

Pressing 2 0 0 LN = will give you the natural logarithm of 200. If you need the common (base 10) logarithm, divide the result by the log of 10.

( 2 0 0 LN ) / ( 1 0 LN ) =
will give you the common log of 200.

Easy,
2nd>7 (DATA)
X01= put the first figure then ENTER
Down arrow two times
X02= put the second figure then ENTER
Down arrow two times .. and so on
till the list finished
press 2nd>8 (STAT)
down arrow
and find your stastics

Check the BEGIN/END setting (2nd [BGN]) and the number of payments per year (2nd [P/Y]). If these are set correctly, could you post the problem you're trying to solve, giving both your results and the expected results?

If the interest is compounded monthly:

2nd [CLR TVM] (clear any existing results)
1 5 0 0 0 _/- PV (present value, negative because you're paying it out)
6 I/Y (annual interest rate)
25 2nd [*P/Y] N (25 years)
CPT FV (compute future value, see 66,974.55)

If the interest is compounded annually:

2nd [CLR TVM] (clear any existing results)
1 5 0 0 0 _/- PV (present value, negative because you're paying it out)
6 I/Y (annual interest rate)
2nd [P/Y] 1 ENTER 2nd [QUIT] (one compounding period per year)
25 N (25 years)
CPT FV (compute future value, see 64,378.96)

If $100,000.00 loan: enter 100000. in pv, if interest rate is 5%, enter 5 divided by 12 = %i if 30 year mortgage, enter 360 N enter 2nd PMT to get monthly principle and interest. You may have already solved this problem.
