Question about Texas Instruments TI-83 Plus Calculator

I don't know where to find k in my TI-83 plus culc. to solve FV. If you know will appreciate for your respond.

Press the APPS key and select Finance. If there is no Finance entry, then you need to load the Finance app, which you can get from the calculator CD or download from http://education.ti.com

"ComPuTe". On TI financial calculators you have to press the CPT button before pressing the button for the value you're solving for. (N, I, PV, PMT, or FV). On an HP calculator, you just press the N-I-PV-PMT-FV button without making any entry in order to solve for the desired value.

Were you also clearing the financial memory with 2nd [CLR TVM], or just the storage memory? If you don't, it's going to keep using whatever value you last used for PMT.

Selecting END merely sets the payments to occur at the end of each period, as opposed to the beginning. The default setting is END, so selecting it changes nothing. If you want the PMT, move the cursor to the PMT field, then press ALPHA [SOLVE].

Thirty year mortgage for $200,000, 8% annual interest. What is the monthly payment?

Press the APPS key. Select "Finance". Select "TVM_Solver..." For N enter 360 (30 years of 12 months). For I% enter 8. For PV enter 200000. For FV enter 0. For P/V and C/V enter 12 if they're not already so. Select "END" on the last line. Move up to the PMT line and press ALPHA [SOLVE] (ALPHA ENTER). You should get a payment amount of $-1467.53 (the negative sign indicates what you pay out).

If you were trying to find the roots (zeros) of an algebraic equation
with the solve( command or the interactive solver you might have
supplied an interval where the function is always positive or always
negative. If the expression is always of the same sign on an interval,
the interval does not contain a root.

- If you extend the interval, the procedure may not converge fast enough and the calculator may not find the solution.
- Abetter way to do it is to sketch the graph of the function and use the graph to choose a reasonable interval that extends on both sides of the root, and a better initial guess.

- You attempted to calculate the I% variable when FV, N*PMT, and PV are all positive, or all negative.
- You tried to calculate Irr( when neither CFlist, nor CFO is positive
- You tried to calculate Irr( when neither CFlist,
nor CFO is negative

I get 6.085%. Make sure the fv and pmt are of opposite signs. You're either making annual payments and getting a lump sum back at the end, or receiving annual payments and then paying it all back in a lump at the end. Either way, the money is moving in opposite directions.

Click APPS and then ENTER for Finance and then ENTER again for the TVM Solver. There you can input the PV, PMT, i, etc.

Press APPS and select the Finance app. Select the TVM Solver.

Enter -4000 for PV, 0 for PMT, 6000 for FV. Be sure you use the (-) key for PV, not the - key. P/V and C/Y should both be 1 and PMT should be END.

If you want 5% annual interest compounded month, enter 5/12 for I%. If you simply want 5% annual interest, enter 5 for I%. Go to N and press ALPHA ENTER to see the number of periods (months or years according to what you entered earlier in this paragraph).

Use the (-) key next to the decimal point to enter the negative value, not the - key.

I'm going to make up an example so this is easier to answer.

Ex: You have a bond with a price of $987, with a coupon of 1.5%, which matures in 10 years.

To do this problem:

[APPS] [1] [1]

What comes up on screen:

N=

I%=

PV=

PMT=

FV=

This is all the stuff that you really care about.

Now, add in the info you know from the equation. Put in a 0 if you don't know the number for that part.

This is what it should look like:

N=10

I%=0

PV=-987

PMT=15

FV=1000

Now, cursor back up to the I%=0 part.

Highlight the '0' that you had in there from before.

[ALPHA] [ENTER] ----> notice above the enter button it says in green lettering "solve", this is what you are trying to do.

Yay! Your caluculator has now figured out the interest rate!

it should say:

I%=1.642027191

Notes:

1. Make sure your payment is set at the end of the period (this is just the standard so you probably don't want to mess with it.) Scroll down to the PMT: END BEGIN part and make sure the END is highlighted.

2. This example used annual coupon payments. The p/y and c/y business is used for when you have semi-annual payments or semi-annual compounding (or daily, or hourly etc). You can use this feature, or you can just adjust the payment and periods

(ie: if this were a semi-annual coupon bond, the N would be 20 and the pmt would be 7.5)
