Where is the compute button on this calculator when solving tvm problems

Actually, you don't need the y^x key.

Clear the financial registers with 2nd [CLR TVM]
Enter the present value: 1 0 0 0 0 0 0 +/- FV
Enter the future value: 2 0 0 0 0 0 0 FV
Enter the interest rate: 7 I/Y
Compute the number of periods: CPT N

According to the manual, error 1 indicates "Overflow", a number whose magnitude is greater than 9.9999999999999E99. Error 5 indicates "No solution exists", for example when FV, (N*PMT), and PV all have the same sign.

If you still have trouble, please feel free to reply to this post, giving sample problems producing these errors.

The calculator has different worksheets.
To access TVM worksheet, press [2nd] and any TVM key : N, I/Y, PV, PMT or FV
To enter Amortization worksheet, press [2nd][AMORT]
To access Cash Flow (problem with unequal cash flows) Press CF, or NPV, or CPT or IRR
To access BOND worksheets press [2nd][BND]
For depreciation worksheets press [2nd][DPR]
For statistics, use [2nd][DATA], or [2nd][STAT].
There are other worksheets [2nd][Delta%], [2nd][DATE], [2nd][PROFIT], [2nd][BRKEVN],[2nd][MEMory].

These shortcuts will not get you anywhere if you do not consult the manual.

2nd [CLR TVM] (clear TVM registers)

2 4 0 0 +/- PV ($2400 initial investment, negative because you're paying it out)

6 I/Y (6% annual interest)

1 N (one year)

CPT FV (compute future value, see 2544.00, the value after one year)

5 N (five years)

CPT FV (see 3211.74, the value after five years)

1 0 N (ten years)

CPT FV (see 4298.03, the value after ten years)

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.

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.

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)

2nd [CLR TVM] (clear old data)
6 2 5 PV (present value)
8 I/Y (annual interest)
1 2 8 4 +/- FV (future value)
CPT N / 1 2 = (compute number of months, divide by 12 to get number of years)

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

Best of luck

There isn't one. In the TVM solver, use the arrow keys to put the cursor on the desired value and press ALPHA [SOLVE] to have the calculator compute it.
