Hi,

I need to calculate out nvp and irr (finance) and my TI-84 just gives me the "ERR:ARUMENT 1:Quit 2:Goto" when I've put in all the data and press enter. Can you give me the detailed runtrough for puncing in data for solving? Please? Im really struggling and can't seem to figure out what i do wrong. I use both the ( ) and [ ] when i type in....
need to compute NPV and IRR

This link covers all financial applications that can be done with a TI-84 calculator:

http://hbelabs.com/TI84/ch14.pdf

TVM calculations work better when using the lists in that state mode and using L# (# meaning the number of lists to link the command) as described on page 251.

A complete manual is available at the website education.ti.com under the TI-84 support section.

Before using any TI-84 series manuals, make sure that you have the correct manual that applies to your operating system. Some manuals (and textbooks) have been modified for mathprint use and some have not. It is advised to use the TI-Connect software to update your calculator to the current operating system that supports mathprint whenever possible.

Are you using the finance app?

[APPS] [1] [ENTER]

For NPV, choose "7:npv("

Then use:

npv(interest rate, cost {cash flows}, {frequencies of cash flows})

For IRR, choose "8:irr("

Then use:

irr(interest rate, cost {cash flows}, {frequencies of cash flows})

SOURCE: Calculating out npv and irr

Use the "FINANCE" app:

[APPS] [1] [ENTER]

for npv: select "7:NPV"

now you should get "npv(" on your screen.

use: npv(interest rate, cost {cash flows}, {frequencies of cash flows})

for irr: select "8: irr"

"irr(" will come up.

use: irr(interest rate, cost {cash flows}, {frequencies of cash flows})

Could you post the function you're trying to plot? Please give the exact sequence of keys you used to enter the function.

If I had to guess, I'd say you're using the "-" key when you should be using the "(-)" key.

To calculate IRR and NPVEnter the cash flows as follows, remembering the sign convention:

I did not come up with this solution. Just found it for you.

- Clear previous data by pressing
**fXY**and**fCLX.** - Enter the cash flow at time zero using
**# gPV**[**# CF0**]. - Enter subsequent cash flows using
**# gPMT**[**# CFj**]. - If a cash flow is repeated, enter the number of times it is repeated (including the first time you just entered) using
**# gFV**[**# Nj**]. For example, three equal flows in a row would be entered as**3 Nj**. - When you have entered your last cash flow:
- If you are calculating an NPV, enter your interest rate as
**# i**(consistent with interval between cash flows) followed by**fPV**[**NPV**]. - If you are calculating an IRR, enter
**fFV**[**IRR**].

You're probably using the - key to the right of the 6 key to enter a negative value. Use the (-) key to the right of the decimal point key instead.

Press the Y= button.

There are several possibilities:

1) Scroll through all equations, Y1 through Y9 and Y0. Make sure they are cleared.

2) The equation you typed in is not entered correctly.

3) Make sure Plot 1, Plot 2, and Plot 3 are NOT highlighted.

Hi,

If you want to know exactly where there is an error press the 2:Goto and the cursor will take you there. The message is clear: Some data you input is not of the right type.

Since you do not say much about what it is you are trying to do statistics on, I for one cannot guess. I suggest you press the STAT key and select 5:SetUpEditor then press ENTER.

Hope it helps.

Thank you for using FixYa.

Hello,

You should give the whole error message.

I created a bogus program and archived it.

Then I tried to execute it. I got the messages: ERR Archived 1:Quit 2:Goto. When I tried to edit it I got ERR:Archived 1:Quit.

Your program is archived. You must unarchive it.

To Unarchive. Press [2nd] [MEM][2:Mem Mgmt/Del] [ENTER]

Scroll down to [7:Pgrm]. Archived programs will have a star at the left. Highlight the program you want to unarchive and press [ENTER]. The asterisk disappears. Press [2nd][QUIT]. Your program is ready to run or to be edited.

Hope it helps.

Press the 2nd Button then the ZOOM button. Make sure that AxesOn is highlighted. If not, move your cursor down until you on AxesOn and press ENTER.

If AxesOn is highlighted, then it is probably your window. Press ZOOM, then 6.

for npv: select "7:NPV"

now you should get "npv(" on your screen.

use: npv(interest rate, cost {cash flows}, {frequencies of cash flows})
