Question about Texas Instruments BA-II Plus Calculator

Error 5 indicates one of two conditions while doing a TVM calculation.

1) You tried to compute the interest rate when FV, PV, and PMT all have the same sign. Make sure cash inflows are positive and outflows are negative.

2) The LN input is not greater than zero during calculations.

The first is much more likely.

It's a little tough to diagnose with what you've given. Could you post all the numbers you're putting in, the result you're getting, and the result you expect?

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 .

The 107,186.37 is what the future value would be if the interest per month is 0.58%, which is 6.96% per year. Try the following:

2nd [CLR TVM] 1 2 N 7 I/YR 1 0 0 0 0 0 PV CPT FV

As for rounding, you can change the calculator display to any number of digits (up to a limit, of course) by pressing 2nd [FORMAT] and then a number specifying the number of desired digits after the decimal point or 9 for floating decimal.

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.

It's more common that one of the settings is not correct. Check the BEGIN/END setting, the number of payments per year, and the number of compounding periods per year.

If you still have problems, please give an example of a TVM problem, with your results and the correct result. Simply saying "incorrect results" doesn't let anyone help you.

Before each calculation of a TVM problem you must fully clear the calculator ... Press [2ND] [CPT] [2ND] [FV]

Best of luck
