# Forecasting Based On Two Years Of Data

Nov 21, 2011

Have to forecast/create a trend for the current year based on the data available for last two years. Below is the format of data. The current year data is kept blank as the data needs to be filled based on forecasting/ trending.

## SEASONALITY Based On Names Of Months In Forecasting Model

Jul 16, 2007

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%.

## Forecasting Using Historical Seasonally Effected Non-linear Data

Jan 15, 2010

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?

## Adding Years To A Date (taking Into Account Leap Years)

Aug 28, 2007

I have a date 07/28/2027 and need Excel to calculate a date 65 years in the future taking into account leap years.

## Display Number Of Years Based On A Date

Mar 28, 2009

Right now, in a column I would like to display an number (length of employment) based on the hire date.

In one cell the employee's hire date is entered. In a column of other cells the pay period ending date is displayed and in another column the length of employment is displayed.

Example:

03/17/2000

03/01/2009 8
03/15/2009 8
03/29/2009 9
04/12/2009 9
04/26/2009 9

How would I create a formula in the length of employment cells that would indicate the correct number of years based on the hire date and adjusts when the pay period date passes this hire date?

## Conditional Formatting Based On Number Of Years From Now

Dec 17, 2013

I have a list of 2000 pieces of inventory. Only the year of purchase is associated with each one, not a specific month or day. I'm trying to apply conditional formatting so that...

Less than 2 years old = green
Between 2 and 4 years old = yellow
Between 4 and 6 years old = orange
More than 6 years old = red

I've been trying =TODAY()-365 (365 replaced by number of days in the above named ranges) but the cell only changes to the color of the most recently applied formatting rule.

## Forecasting Setup

Sep 14, 2006

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?

## Seasonal Forecasting Trend

Apr 2, 2009

I'm trying to figure out how to do seasonal forecasting based on volumes. I tried to use FORECAST but the numbers are not accurate.

I have actual data to work with to come up with my forecasting on a monthly basis. Our yearly calender is from Nov 08 to Oct 09.

Here's a sample of the data....

## Calculating Total Forecasting

Jul 15, 2009

## Sumproduct :: Forecasting Purposes

Oct 19, 2009

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.

## Assistance With Budget Expenditure Forecasting

Jun 19, 2008

I am trying to use excel to forecast budget expenditure for the fiscal year, using actuals from months past + unknown (future months).

## Forecasting Multiple Store Openings

Dec 8, 2008

I have a base model for site openings and opening schedule. I need to build a 5 yr model which reflects the base model for each opening. I have matched the month in the model to the opening month but how do I get the base model subsequent months to follow the opening month?

## Macro Using Transpose Function For Multiple Years Of Data

Jul 6, 2014

I need to create a macro in excel that will take data for a particular year in vertical rows and transpose it to horizontal rows.

What the data originally looks like:

380204198401014.72
380204198402016.34
380204198403015.66
380204198404013.71
380204198405013.86
380204198406013.51

[Code] ........

What I want the transposed data to look like:

StationYearJanFebMarAprMayJunJulAugSepOctNovDec
38020419844.726.345.663.713.863.5113.69 3.611.362.812.522.25
38020419853.194.211.021.292.372.416.082.500.143.196.122.04

I have never written a macro before and have tons of records (over 40,000) so using this will save me a lot of time.

Sep 21, 2013

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...

VB:
Shift:=xlUp, CopyOrigin:=xlFormatFromRightOrDown

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

## Forecasting Purchasing: Setting Up A Spreadsheet That Will Allow Me To Look At Previous Orders And Forecast

Apr 11, 2007

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.

## Date Fields Increase Date By Numbers Of Years Based On Lookup Table?

Aug 11, 2013

d1 e1
Restricted 5
etc

Example of data
ie.
a1 b1 c1
Restricted 1/06/2012 1/06/2017

What I am looking for is a formula to look up a1 "restricted". then lookup the security table and find "restricted" its value is 5 (years) then add the 5 years to date in b1, but place it in c1.

## YTD Sum Across Multiple Years

Jan 14, 2009

I need to calculate YTD sums using the data that spans three years. I am using

SUM(B2:INDEX(B2:AC2,MATCH(\$B\$10,\$B\$1:\$AC\$1,0))). This works fine if all of my data is contained in one year. However, when my data spans multiple years it does not. For example, if I have the following and today is April 2007 I want to calculate Jan-April 2007.

## Dates, Number Of Years

Dec 15, 2008

I have two dates, one is a start date the other is todays date, I want to subtract the start date from todays date and show the number of years. But a small twist is I only want to take the years away from each other, ignore day/month. Start 01/05/2000 todays date 01/10/2008 years = 8. Start 10/10/2000 todays date 01/10/2008 years = 7, want it to still show 8 years and ignore the start day/month.
