# Calculating Total Forecasting

Jul 15, 2009
I have a row of totals in a spreadsheet and I want to calculate a forecasted total based on the previous month's totals.

For example I have two months and I want to know how to calculate the forecasted Jun 09 total: ...

I want to calculate a running total (so add a new value to its original value). For example, cell A1 is the one I will be changing daily, and cell B2 is the one that I want a running total in. So if I start with A1 being 5, B2 should be 5. If the next day I type in 3 into A1, B2 should now read 8. However I want to do this for a column length, not just cells A1 & B1. So column B would be the running total of the column A values. If A2 is 3 one day and the next it is 6, B2 should on the second day read 9. And on and on down the columns.

I tried doing this without VBA using iterations, but that didn't work. Every time I did that it would add values going down, which was weird cuz none of the cells referenced the cell above it. I didn't know if they would work since I have multiple sheets in this file. (I'm only calculating the running total in one sheet, the others aren't doing anything special.) I need all the sheets in my file and I didn't know if VBA modules are sheet specific/ if you need to be sheet specific when coding.

Another question I have (since I know nothing about VBA) is how do modules work? Do you need to turn them on in the Excel spreadsheet itself? Or when you save it does it just automatically apply itself to the file its attached to?

On another note, how to do this WITHOUT VBA, that would be like 100x more fantastic.

in my worksheet i have different kind of items with its cost. in my case which is not in order, that is, the order of items can be AABAACCBA. I want to calculate Cumulated Total on each row. but i am not sure how to achieve this by conditional formula? the values in my sheet looks like the following,

Date ITEM TYPE AMOUNT Cumulated Total

10-Jan-07 BookA1010 -value(Book)

11-Jan-07PenA515 -value(Book+Pen)

12-Jan-07TableB1515 -value(Table)

13-Jan-07PencilA2035 -value(Book+Pen+Pencil)

14-Jan-07ChairB2540 -value(Table+Chair)

15-Jan-07SofaB3575 :

16-Jan-07RoseC2020 :

17-Jan-07Calc...A3065 :

18-Jan-07JasminC1030 -value(Rose+Jasmin)

find the attachment for reference. How to achieve this using conditional statement or lookups or someother? and i try to avoid macro.

I'm trying to calculate total occurrences of a given month. I have included the spreadsheet for reference with totals.

I only want to calculate when the Policy column has a "N". If it has a "Y" I do not need to do anything

If the Policy has a "N" I want the formula to look at the V and P columns and give me a total in the Total Occurrence column. I want it to look at the entire month for a grand total.

If the V or P column has a 4 or less it should equal 0.5, if it has a value is between 4 and 10 it would equal 1. So in the Total Occurrence column should calculate the all of the 0.5 and 1's based on each set of columns and give a total. In the example that I have given in the spreadsheet the total in the Total Occurrence column would be 2 because Jan. 1 has a N and a 8 which equals 1 and Jan. 3 has a N and a 4 which equals 0.5 and Jan. 5 has a N and a 4 which equals 0.5 for a total of 2 occurrences.

I am working on this for two days , but I got stuck on the last step. I have a roster for about 35 employees. Calculating the daily hrs was not a problem. But I am doing the roster for one week. And I want employee wise total of hrs worked. I am quite confused as the "sum" formula works for some totals and for others it does not, although all the cells are in the right format. I tried to change the "result" cell to "number" and multiply by 24 to get the hr total as a number, but it does not work.

for example "SUMIF(E1:E57,"rafik",H1:H57)" ( this is the formula for calculating hrs for "rafik" on monday. the result cell is in "hh:mm" format and gives me the right total.

Likewise upto sunday the totals are right. What I want to do is calculate the total number of hrs from mon to sun. This seems to be impossible. the formula =SUM(H60:AL60) in a dd:mm format does not work, even =SUM(H60:AL60)*24 in a "number format" does not work.

I have tried "excel help" , tried to change the format but nothing works. The result should be 52 hrs and I cant get it no matter what I do.

I'd like excel to calculate 3 totals for me based on the colour and value on a worksheet.

Basically, I work for various people and they pay at different rates per hour.

I currently have a spreadsheet with their names, times, and rates (see attached for example), but I calculate the amounts paid and due manually.

If possible I would now like excel to do it.

To explain further, 'J' gives me $10 per hour, and 'V' gives me $5 per hour.

Cells shown in red show work done but not paid for.

Cells shown in green show work done and paid for.

I'd like excel to automatically create totals as shown on the spreadsheet, namely:

Total due: xxxx

Total paid: xxxx

Total outstanding: xxxx

At any time during the month I can be asked to take on more work - I would then enter the code into the spreadsheet for the hours requested...and I'd like the totals to be update automatically.

I need to calculate the total cost of outbound calls based on the total duration of outbound calls multiplied by cost per minute. For example, in a given month, the total duration of outbound calls is 261:16:34 being 216 hours, 16 minutes and 34 seconds. I have this figure in cell A1 with the format [h]:mm:ss. I then convert this to minutes in cell B1 by saying B1=A1, but having the format [m], which gives me 15676. In cell C1, I have the cost per minte value of £0.026. But when I apply the formula D1=B1*C1, I get £0.283, when 15676*£0.026 should in fact be £407.58.

I have a workbook with each month as a tab Jan 2014- dec 2014. I have a totals page that's has total billings( the sum is adding all the totals of each month). The totals for each month are in different cells based on the number of individual invoices I enter for each month. I have entered jan- march invoices. I would like to put in a formula on my totals sheet that gives me a ytd avg without changing it. ie: d4/3 then next month april d4/4.

Using Excel 2002. Here's my problem.

Column A contains the month (as text)

Column C contains an employee name.

Column O contains a reason for absence.

Column K is the number of hours of absence.

The employee's name may appear several times in the worksheet. What I want to do is count the number of hours per type of absence.

E.g. If A=MAY and C=BOB and O=SICK then total hours from all instance of K = X.

This will be used on a seperate worksheet where the name C will be referenced from a validation list.

I am trying to come up with a formula that calculates total time someone has worked in a day. The scenario is an individual will work at a home and start working with an individual. Their start/end times look like this in a pivot:

Min Start Max Start Min End Max End

Location A+Counselor A 8:56 AM4:01 PM 1:11 PM 7:00 PM

Location A+Counselor B 12:00 AM 8:00 PM 6:00 AM 11:59 PM

Location B:Counselor C 7:00 AM 12:00 PM 2:00 PM 4:00 PM

Location C+Counselor D 8:00 AM 8:00 AM 4:00 PM 4:00 PM

Some people work split shifts while others work a straight shift. The formula I created was this:

=IF(OR(B9=C9,E9=D9,D9=C9),E9-B9,IF(D9>C9,((E9-D9)+(C9-B9)),IF(C9>D9,((D9-B9)+E9-C9),"New Formula Needed")))*24

(I use a pivot table to show max min for start and end times)

This works great except for the individuals that have multiple punches during the same time frame. The one scenario I am having trouble solving for is when someone punches in more than once during their shift displaying. This occurs when a counselor starts a shift working with one person but then adds another person mid shift. An example of this could be:

Location A+Counselor E Min Start Max Start Min End Max End

Consumer 1 1:00 PM 1:00 PM 8:30 PM 8:30 PM Total Time: 7.5

Consumer 2 12:00 PM 12:00 PM 2:35 PM 2:35 Pm Total Time: 2.6

Pivot says that they worked a total of 10.1 because it is grabbing the max and mins and calculating. The actual total time worked is 8.5 hours in reality.

The raw data comes in like so:

Location Counselor Consumer Start Time End Time

A A A 1:00 PM 8:30 PM

A A B 12:00 PM 2:35 PM

A A C 12:00 PM 5:00 PM

Is this solvable with a formula?

I have set up a spreadsheet to calculate time as followed:

A1 - Start Time

B1 - Finish Time

A2 - Hours Worked:

=IF(B1<A1,B1+1,B1)-A1

C1 - Start Time

B1 - Finish Time

C2 - Hours Worked:

=IF(D1<C1,D1+1,D1)-C1

and so on.........

I need creating a formula that will tell me the total number of employee hours worked during a certain hour (6:00 AM) for a particular department. Some employees clock in at 6:00 AM, some clock in at 6:30. Here is the current formula I'm using which only tells me the amount of employees in the department not how many hours worked . I have three employees that clock in at 6:00AM and one at 6:30AM, the total I'm looking for is 3.5 but my formula gives me the result of 4.

C5:C1446 is a list of departments

T1503 is the 6:00 AM

D5:D1446 are the Clock In times

K5:K1446 are the Clock Out Times

=SUMPRODUCT(--($C$5:$C$1446="Shipping"),($T$1503>=$D$5:$D$1446)*($T$1503

Excel ( 2010 ). I am creating a Sales Leads spreadsheet. Within the spreadsheet I have a the following relevant fields.

proposed sales value field ( F2 ), Estimated Close - which will be Q1,Q2,Q3 or Q4 ( G2 ), % Probability ( H2 ) & Q1 ( I2 ), Q2 ( J2 ), Q3 ( K2 ) & Q4 ( L2 ).

F2 = 150

G2 = Q2

H2 = 10%

I want to calculate the actual value of sales based on %prob and put the total into the correct field ( I,J,K or L ) based on what field G2 says. So in this case 15 into field J2. I have attached an example.

If I have a database of 1000 records that are logged and counted as to which of these records are successful and unsuccessful sales,

can excel be programmed to give an accurate forecast of what will be the number/ percentage of successful sales records over the next 100, 50, 30 and 10 new record entry ranges, using the database history?, then which of the new records within each selected range are most likely to be successful sales using the database history?

If so, what components or data references are needed in a worksheet to meet these requirements to allow for creating an accurate forecasting application within excel?

I have an excel workbook which requires us to enter the log details of some sites and then a report is generated using these logs (report attached) . [URL] .......

I want that excel should automatically identify the site and calculate its outage with the following formula:

Outage %age= Total Outage(min)/100.80

and add it in the respective column while identifying the outage.

e.g. if outage is of power then the calculated %age outage should be pasted in the power outage column in front of the respected site.

e.g. in the sheet attached above the first row in the first sheet states that SKU2326 was down for 50 mins

Now %age outage will be

Outage %age= 50/100.80

Outage %age=0.496

Now as the outage is related to power so this outage should go into power column in sheet number 3 labelled as "Network Total Up time Week#17"

Now the next time SKU2326 becomes down it should be added with this 50 mins and the outage calculated as presented above.

I am trying to come up with the appropriate formula that can be used for possible forecasting purposes. Countif proves to be futile due to more than one criteria that needs to be met. Sumproduct seems to be more feasible but I am unable to get the correct formula or maybe I am wrong.

Here's the objective...I need to be able to plot the total number of people working on a project on a daily basis - # of people working on a Monday, Tuesday and so forth by means of referring to start and end date column..I am open to revisions so as to streamline everything.

I thought about using it for forecasting purposes. I might try to use it together with live data (temperature, seasonal patterns)... but if I graph it, it starts from left to right...

How to modify the code a bit...

Shift:=xlUp, CopyOrigin:=xlFormatFromRightOrDown

I tried to change the code, but it did not worked.

Forecasting using historical seasonally effected data

I organize my thoughts in numbers so it will be easier to understand.

[1] Say I have this data from January 2009 to December 2009:

1-4-7-10-13-14-15-16-18-20-22-25

As you can see, the growth is not linear.

[2] So then, I start with this data point for Janaury 2010.

26-a-b-c-d-f-g-h-i-j-k-l

[3] I now want to forecast that data point for the rest of 2009...using the growth in [1]. SO i guess that's an easy task right? Take the percentage change from Jan 08 and Feb 08...and apply that to the 26...and so on. (am i correct here at least).

[4] But lets say we have a GOAL. So, this become a forecast/plan. In December 2010, i want to grow double the amount of that in December 09. So 25 x 2 = 50. Now, the "known" data is like this:

26-a-b-c-d-f-g-h-i-j-k-50

So how do i do this now?

I have historical sales for each month from the last 3 years. I would like to set up a seasonality adjustment for forecasting. I know that it won't be perfect and some may even suggest using regression, but I'd rather not. I'd like to do the following:

In a control sheet, list the months in chronological order beginning in cell A1; January, A2, February; etc., etc. through December.

Next, below each month, I'd like to have a factor. For example, in B1 beneath January, I'd like to be able to plug in 75%. This would say that for each January going forward, that it is 75% of the annual historical average for all periods. Whereas, say in June, it is 140%.

how I would go about setting up a spreadsheet that will allow me to look at previous orders and forecast what I need to buy. He never got into trouble for ordering too much, but he did get caught on ordering too little. I am thinking something along the lines of the attached. However, if anyone is using something that looks or works better (or those who solve this little problem have done a better looking or working sheet) let me know.

There will be some Vlookups that need to bring in description and price (or some other function if there is a better way to do it). The min need and max need will be populated and brought in by vlookup. The order column should be where the forecasting happens based on previous orders. I am willing to have all the data in the same workbook. The second or third sheet can be used to store data in what ever format that is needed to be done.

I have a report which has a list of customers, each customer has 24 columns which represent the payment history over 24 months. If a payment has been made for that month the date and time (formatted correctly) will be populated in this cell.

Each customer has a product name attached to it so a product can appear several times. I need is a formula that shows the total payments recieved for a particular month for a particular product. For example.

I have managed to create the following flag which works a treat, it picks up a date an account was set up but looks at 1 column.
