Computing IRR calculator goes blank and outs Error 7

When computing IRR, after the cash flows are entered, the calculator goes blank for a very long time, over a minute and or two and then finally pops out "Error 7". We have experimented with various cash flows, problem persists. Looking forward to any help.

I belive this will fix the problem i was sitting here having the same deal waiting and waiting..then bam error 7 then i fixed it so thought i would put what i did.

go into your CF and delete all the unused CO times..for instance if your using 3 periods...delete all CF05 and F05 the last one should be C04=0 and F04=0 make sure your NPV is the same after messing around..then try to compute IRR popped up in 2 seconds for me.

word hope this helps u all ***420*** :0

As with many financial calculators, the programmed instructions will sometimes cause an error in results if cash inflows lead to computations that can not find the IRR or other financial measures. This problem exists in MS Excel as well. What I suggest is try using FinanceEasy which is an online freeware financial calculator at Asad S. Yousaf

The following problem is not difficult, however, I am having trouble calculating the answer using my HP 12c Platinum. Can you please provide a step by step explantation of how to calculate the answer to...

1. Make sure the HP-12C is in compounding mode. Press STO-EEX repeatedly until a tiny "C" appears in lower right of display.
2. Make sure "BEGIN" is NOT shown in the display. If it is, press g-END.
3. Clear financial registers: f-FIN. (That is really the "f" key then kind of the "Clear FIN" key -- I'm sure you'll see it.)
4. Enter zero as "initial investment". CLx, then g-CF0. (You have to do this because the 12C actually computes the "NPV" as an excess or deficit over the entered "initial investment". By entering zero, you force the calculator to just give you the actual net present value.)
5. Your first cash flow is +2.00. So, enter 2.00, then press g-CFj.
6. Next cash flow: +2.10. Enter 2.1, then press g-CFj.
7. Last cash flow: +22.20 (the final value of the stock plus the last dividend payment). Enter 22.20, then press g-CFj.
8. Enter the 10% interest (a.k.a. discount) rate. Enter 10, then press "i".
9. Compute the NPV. Press g-NPV. The answer is indeed 20.23 (at least to two decimal places).

Hello I bought the Texas Instruments BA 2 plus,how to change 2 fin mode?there is no mode button.

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.

How to Calculate IRR?

To calculate IRR and NPVEnter the cash flows as follows, remembering the sign convention:
  • 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 as3 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].

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

Casio fx-991ES, how to calculate NPV and IRR

At a blank screen, enter your IRR formula in terms of the variables using ALPHA and ')' for variable X. For example: -1000 200/((1 X)^1) 200/((1 X)^2) ... rest of subsequent years. Then, press CALC. It will prompt you to enter values of your variable (X in this example). Don't worry if there's already a value displayed - this is just the most recent value that has been stored as that letter. Simply enter your value (in terms of your IRR guess) and then press [=]. You will have to repeat this for each IRR guess until you reach almost ZERO.

Why do i get error 5 when trying to compute IRR

Error 5 indicates that no solution exists. In an IRR problem, the most likely cause is that there was not at least one sign change in the cash flow list.

Excel 2007

The IRR function is provided by Excel so you can calculate an internal rate of return for a series of values. The IRR is the interest rate accrued on an investment consisting of payments and income that occur at the same regular periods. In the values provided to the function, you enter payments you make as negative values and income you receive as positive values.
For instance, let's say you are investing in your daughter's business, and she will make payments back to you annually over the course of four years. You are planning to invest $50,000, and you expect to receive $10,000 in the first year, $17,500 in the second year, $25,000 in the third, and $30,000 in the fourth.
Since the $50,000 is money you are paying out, it is entered in Excel as a negative value. The other values are entered as positive values. For instance, you could enter –50000 in cell D4, 10000 in cell D5, 17500 in cell D6, 25000 in cell D7, and 30000 in cell D8. To calculate the internal rate of return, you would use the following formula:
The function returns an IRR of 19.49%.
The ranges you use with the IRR function must include at least one payment and one receipt. If you get a #NUM error, and you have included payments and receipts in the range, then Excel needs more information to calculate the IRR. Specifically, you need to provide a "starting guess" for Excel to work with. For example:
=IRR(D4:D8, -5%)
This usage means that the IRR function starts calculating at –5%, and then recursively attempts to resolve the IRR based on the values in the range.

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})
