Calculating Discounted Payback Automatically In Excel


Hello,
I've been reading through the user forum's and I've noticed that people
have come up with elaborate Macros to automatically calculate the
discounted payback.

In looking at Jaxworks, I've found one possible solution. It's almost
working for me, but not when I start playing around with my cash flows.


The formula is:

=INDEX((Year-CumulativeDiscountedCashFlow/DiscountedCashFlow),1,SUM(IF(CumulativeNetCashFlow<=0,1,0))+1)

All of the words such as Year, CumulativeDiscountedCashFlow, etc. refer
to rows of values.
For example, Year = row of cells with years 0 to 5.

Is there a glitch in this formula?
Has anyone ever made it work before?
Any other suggestions?

Jordan

I have a spreadsheet set up with an employees information, including the start date. After each year that the employee is working, he gets bumped up on the pay scale. For this reason, I only need to know how many years the employee has been working, rounded down to the nearest year.

This is what I have so far (hire date is in column B):

=((TODAY()-B4)/365)&" YEARS"

This function gives me a number with many decimal places.

I tried:

=ROUNDDOWN((TODAY()-B4)/365),0)&" YEARS"

It tells me I have too few arguments. Please help!


Very new in this board. If I post this question in the wrong forum please bear with me.
There is about 20 staffs in our department and I have made a spreadsheet with 12 tabs for each month of the year Jan-Dec. If each staff have 15 days annual leave each year and how can I make a formular that can automatically calculate the balance of annual leave and entered in the tabs of the following months. For example if staff A used 5 days in Jan how can the balance of 10days be entered in the tabs from Feb-Dec. If he use another 5 days in July the remain balance of 5 days be automatically entered in the tab from Aug to Dec. Likewise if staff A took 2 days sick leave in Jan, and 2 days in Mar how can this sick days be automatically sum up in the months after. I am doing this manually at the moment and it is very time consuming and also very easy to make mistake.
Thanks and sorry for this long questions


I have a spreadsheet where I need to calculate the increase in % one year over the other in column D for Eg if Profits are 95415 in Jan 2008 (Column B) and 80215 in Jan 2008 (Column C), then the % Increase will be (95415-80215)/80215 *100

I can calculate the formula for this, but the problem comes where for eg there is a loss in Jan 2008 for -95415 and there was a profit in Jan 2007 for 80215. How do I set up formula to take negatives & positives into account in calculating the increase or decrease/

Your assistance or anybody's on the forum will be greatly appreciated

This formula is supposed to calculate difference between today and date hired to give years and months of service. Works fine for all except if the person was hired in year 2000 then this formula shows 110 y. Any one know how to fix this? or have a different formula that works.

I have sheet with rows and each row has formulas based on cells in that row.
I would like to have a new row automatically inserted with the formulas
updating to reference the cells in the new row. Let's say I start with 50
rows and after they are filled up, a new row is added automatically? How do I
do this?



Good afternoon!

I'm working with Excel 2003 sp 3 on Windows xp.

I have been banging my head trying to jar loose the formula to calculate man days where 1 equals 8 hours. I have one that was given to me by a coworker:

=INT(Q3/8)+(((Q3/8)-(INT(Q3/8)))*0.8)

That calculates man days from total hours. I need a formula that will total man days and return the man day answer. Example:

weekending 12/25 = 16.2 which is 16 man days and 2 hours
weekending 1/1 = 24.7 which is 24 man days and 7 hours

Total = 41 man days and 1 hour

I have also been asked if there was a way for a number to be entered into a spreadsheet and automatically put in order without a macro or "pushing a button".

Any advice is greatly appreciated!

Happy New Year!

Hi,

I am entering lots of family history data into a spreadsheet. At the simplest I have columns (in cells A1 B1 C1) the headings, Surname, Forename, Year. Right now, I enter in cells A2 B2 and C2 say: Smith <Tab> John <Tab> 1555 <Enter, move mouse to the A column in the next row down). What I want to happen is when I have entered the last data in a row and pressed <Enter> I move automatically to the A-column in the next row down.

Is this possible?

Regards and a Merry Christmas to all

I have noticed that a handful of people at work enter a formula as =+A1+A2 instead of the way I would enter it =A1+A2

What is the origin of the extra plus sign at the beginning? To me it seems to be unproductive and is simply not needed. I have been using Excel for over 12 years and have never needed to enter any formulas like that. Does this originate back to a much older version of Excel where it was once needed?

Just curious.
Thanks.


Hello everyone!!!!

Here is my situation. I have been trying to learn macros but have not made one yet. Need your help. Here at work, I have some incompentant computer workers who claim they KNOW MS sooo well and have certificates etc... *COUGH COUGH* ya ok... LMAO

We have a "shared" work book we all work in. It's nothing fancy, just use it as a PO Book but since it is shared some people continue to not save before they add in more work so that they see a "refreshed" copy of the workbook before they start writing in cells that already contain information.

How to I create a macro button at the top of the page that is literally a SAVE button.. instead of them saving by going to File - Save or cntrl+s ??? I just thought that MAYBE having a big button in their face will remind them.

Secondly as back up I was wondering if you can create a macro to do a refresh of everyones screens automatically - say every 2 or 5 mins??? I don't mean a save... but a refresh so the screen actually updates in front of you. (although I will keep this little piece of magic out of their knowledge so they don't rely on it, just though it would be a secondary back up to helping eliminate these mishaps cause we are loosing alot of information by people saving overtop of other peoples work and not caring.)

Thanks so much!!!!! Muchly appriciated.


This formula should be very often to use, but i cant found it anywhere, so i ask this here




For example in a1 is :
mike is playing basketball, he is very great player

i want to make it in b1 to be uppercase only in first letter so :
Mike is playing basketball, he is very great player






i know about proper formula =proper(a1), but proper formula is make uppercase to all first letter in all words, we just need first letter in first words to be uppercase (and to every first words after dot if it can)


Today I ran into an odd problem. I typed in values for column A rows 1 through 10 then values for column B rows 1 through 10. then in column C, I made the formula C1=A1/B1. The math was correct it showed 542 in the C1 cell. So I dragged that formula down and it showed 542 in all column C cells which is not correct. And when I went to check to see if the formula was correctly dragged it was. For instance, the formula in C2 is =A2/B2 however the value of that cell showed 542 which was not the correct math/value.

But it gets even more weird. When I click on the Column C cells and then it shows the formula up top in the formula bar and if I put my cursor anywhere in the formula bar and hit Return the formula does not change however the correct value then appears in the Column C cell. It is like the act of putting the cursor in the formula activates it to work properly but until it is activated that C cell shows the value of the cell which it was dragged down from.

This is quite bizarre. Has anyone ever seen this before? I have no idea what is going on. I ran a scan for viruses and none were found. I tried it on several new/different spreadsheets but it keeps happening.

Thanks for any tips on this.


I am trying to work out how to calculate the geometric mean of a series of values, some of which are negative, ie. investment returns over a series of years with some negatives.

The Geomean function doesn't work because it only uses positive numbers.

Any help would be greatly appreciated.


Hi all,

I have a dillemma here,

I have to create a schedule which incorporates lunches automatically (either half hour or 1-hour lunches, depending on the circumstances).

The schedule only has time in and time out, but I need excel to automatically deduct the lunch break depending on the circumstance:

If you worked less than 6 hours = no lunch
If you worked more than 6 hours, but less than or equal to 8 hours = 0.5 hour lunch
If you worked more than 8 hours = 1 hour lunch

I am assuming the formula for this will be really long, but I have looked online everywhere and have not found ONE formula for it. I can't put lunch breaks seperately, so all I have to work with is Time in/out.

Also, I wouldn't be able to use military time, so I don't know how excel can assume that time in is in the morning, and time out is in teh evening and/or half-day.

If someone can help it would be greatlyyyy appreciated


Hi-

I am brand new to Mr. Excel and would love some advice.

I searched the boards pretty extensively but could not find what I am looking for...I apologize if this is a duplicate.

I am using Excel 2007

How do you automatically add rows and update values for cells to a linked worksheet in which rows have been added? For example: Sheet 1, columns A & B are linked to Sheet 2, columns A & B. Sheet 2 has values in A1:A5 & B1:B5 and Sheet 1, since it is linked, has the same info. I want to add a row in between 3 & 4 on Sheet 2 and want Sheet 1 to automatically add the same row and update the value of the cell in column A & B.

Any help is greatly appreciated!

Hi,

Im working with a large data spreadsheet that has Yes and No answers in different columns. There are blanks within the selection too.
I need to calculate only the Yes.
I have tried using the filters in the Pivot Table field list and they are not working.
So now i'm trying to add a COUNTIF formula in the Calculated Fields section.
The formula I'm using is =Countif('Time limit extension'="yes") and i get the answer "too few."
What should I be using in the formula to get the calculated field to work? I have search the whole forum and I haven't found an answer that can help me.

Please HELP!!!


Hello

I'm quite experienced Excel user. I've never come across this problem but tinkering in every conceivable way within Excel settings and the solution has eluded me.

I have added a worksheet created elsewhere (it is a form I need printing, with the data coming from 2 sheets I have created from scratch) which has pre formatted cells for Date and Client Name etc.

When I try to reference the cell in this added sheet from my 2 sheets, instead of the result, it always displays the formula, not the result.

I have tried doing it from one of my sheets to reference to this new, and that displays the result and not formula. I can't imagine why it's doing this and I've never seen it happen before.

Formatting cells, giving cells names rather than the usually adequate of reference to the Cell Number doesn't change things. I wonder if I've picked up some legacy protection from the original form but can't see anywhere in the tools etc that's obvious.

There's about 50+ cells that need referencing and I got to get this done for work.

Please help me. This is my first need to post on a Excel Forum as I've always found help or answers from other peeps or internet but this one is making me scratch my head big time.



Hello from sunny Madrid

I have created a complex formula to help me calculating Golf handicaps for players.


The formula is in the first cell and I want to drag the formula across to the right to cover the 18 holes.

But ALL the values change and I want some to change and some to stay constant.



How do I tell excel to drag the formula across but keep certain parts of the formula the same..ie ....=D11.... in the formula when dragged across doesn't go D12,D13;D14 in each cells formula and should stay as D11 for all.

Many thanks for your help

Hello, I am pretty new to excel programming/messing around so I'll refer to those who are much wiser than I am. I am trying to set up a form for work, in this form I want to have a page with a bunch of cells pre-sized. What I want to do is when I insert a picture from a job site, that when this picture gets inserted, it will automatically resize to fit within the cell. I don't have time to manually resize dozens of pictures and if I could get this to work it would be awesome! I tried to search for an answer using the search function, but I kept getting a fatal error about allowable memory? Thanks in advance for you help!


I need to create a bar chart for the year. I've already have 3 bars for each of the months, a plan, an actual, and a last year. I need to be able to split out just the actual bar, so that it is a stacked bar. The other two bars need to stay and remain unstacked. Is this possible?


I found this solution for "drop down list with hyperlink" but it did not work.

Perhaps a better solution is to use a workaround that relies on the HYPERLINK function to refer to whatever is selected in the drop-down list. For instance, if you have your data validation drop-down list in cell A1, then you might put the following formula in cell B1:

=HYPERLINK(A1, "Goto Link")

The solution directly above provides exactly what I am looking for
in the field where I write the formula, but it fails to hyperlink.
I have created a drop down list and linked each one of them to a
specific worksheet. When I select them individually they link to
appropriate worksheet. But when I select them in the drop down
list I receive the following error when I select the Hyperlink in
cell B1 as directed above.

"Cannot open the specified file"

Any thoughts?
