Determine The Percentage Rate Of Change In A Trendline
Feb 13, 2009
I'm trying to determine the percentage rate of change in a trendline. I've got a sales chart with 90 days worth of sales figures. I can see that the trendline is trending down, but I'm not sure exactly how much.
If you take the first data point in a trendline and subtract it from the last data point and then divide that by the first it should give you the percent change. Excel must be able to do that math for you but I can't even figure it out to save my life. I can't even figure out how to display the first and last data point much less the "rate" of change I'm looking for.
From a chart in Excel I need to automatically calculate what the annual percentage growth rate is of a trend line. How to automate this in Excel? I've attached a sample so you can see what I'm trying to accomplish.
I'm doing an exercise for school and I'm totally confused here. I have to:
With the original assumptions, goal seek to determine what the Annual Rate Increase would be for the total expenses to be $175,000 (answer = 20.77%). Here's what I have: through the process?
I am trying to calculate APR (Annual Percentage Rate) for a mortgage loan that has a balloon feature. I have tried to the the RATE function but it only gives me the APR for a loan that is ammortized over 30 yrs and paid in 30 years. I need the APR for a loan that is ammortized for 30 years with a baloon in 5 years.
What I need is a worksheet which will generate fields from a set of variables (similar to a loan amortization schedule).
I don't know how to write the field code to include the annual percentage rate increase based on that additional input variable.
Input variables would be:
starting rate: (ex: 8¢/kilowatt hour) starting date: (ex: July 2013) average kw hours/month: (ex: 1062.5 kw hours) annual rate increase: (ex: 3% *default 0%) years to display: (ex: 25 years, *shown in months in fields below) service months per year: (ex: 12 *default 12)
[code].....
So, data fields below the variables would be blank until these are entered.
Assume I would protect the sheet to avoid messing it up.
this would generate a chart showing rates over time from the fields below.
Also it would generate fields in a summary area to show the rate per year for future years.
Secondary, if there were a way to input actual usage and rates from specific months in the past, that would be useful but not part of this forecast model.
The goal of this model is to forecast electrical costs for residential power users compared to independent solar power generation to 25 years forward.
I want to make this because I am skeptical of the advertised savings that solar installers use to convince clients that their return on investment is so high. I believe their data to be greatly inflated projections.
Using this in comparison with other data such as inflation and wages will allow me to get a very good economic picture of the future of independent solar energy generation and its impact on the average home owner.
As you can see in the attached sample file, I have different currencies, that all need to be converted to USD.
The exchange rate are displayed on sheet 2.
Currently the formula just picks all values without considering the exchange rate to USD. What I need to have, is a formula which, based on the currency, picks the correct exchange rate and outputs USD.
Apart from that, another thing the formula should consider is the value of G1 in sheet 2. With G1, the user can later define a specific type to be calculated by simply pressing down the button and chose either FG or RM.
The formula needs to:
Find out what currency the value is in and automatically convert it to USD via the exchange rate values. It also needs to consider the value of G1 in sheet 2 in order to filter out the other values. If, for example G1 is FG, then only FG should be taken into the process and therefore only values where type FG is marked.
I have a financial sensitivity sheet setup by year, where for example below each year is a cell you can change the exchange rate in and it effects the outcome of cash flow as these cells are linked to part of the finances. Then I have a "reset" button setup that is assigned to a macro. When you click the reset button all cells in the exchange rate row will be changed to a value that is entered in a "base case" cell. That way various years can be changed but also everything can be set back to the default or base case. My macro for that case is this:
I have wave data and need to extract out of a column the greatest rate of change i.e. start from a1 if the numbers are going down find the first number that starts going upward...and put in column b...then find the next first number that is going down and put in column b....and so on and so on all the way down the column.
The formula I am looking for would tell me what annual growth rate % I would need to achieve to make any investment reach a set target, for instance, what % of fixed annual growth would I need to make 200K grow to 750k in say 10 yrs or any time scale. I was given the formula below but Excel tells me it's wrong, I have tried putting 10 before ^ and the 10 after but to no avail, could some kind soul please put me straight.
I have 26 data points, and I want to be able to change those data points by a certain percentage, defined by a separate single Cell value
Now here's the tricky part: I want some data points to go up by the defined percentage, and some data points to come down by the defined percentage. Which data point goes up and which comes down, can be totally random.
Is there a way of doing this by means of a formula, or is it a VBA job?
6000 - Starting Balance (changeable) 5890 5800 5950 6080 6100 6180 6250 6300 an so on... (1,000 rows)
Based upon the number "20" that I placed in A1 on Tab 1, I want a formula that looks at the first 20 rows in column A within Tab 1, and then calculate the percentage change between the extreme "peak to trough" of the highest number to the lowest number within the 20 rows...
Below should make it really simple:
6000 - Starting Balance (freely changeable) 5890 -1.83% 5800 -3.33% - This was the lowest percentage change from the starting balance of 6,000 5950 -0.83% 6080 +1.33% 6100 +1.67% 6180 +3.00% 6250 +4.17% 6300 +5.00%
In the first picture the Pivot Table is showing the profit of each city in 2010 and 2012. Where I used Sort & Filter Largest to smallest, in order to display the cities with greatest profit.

But when I switch the values to `% of` year (Previous). I get the change from 2010 to 2012 in percentage. But my PROBLEM is when I want to Sort & Filter from Largest to Smallest, cause I want to show the cities that have had the greatest percentage change from 2010 to 2012. But the I only get the same cities, and when I look at ex. 'Gjovik' is has had a 125 % in change and should be in the top.
So how am I able to Sort & Filter from Largest to Smallest the cities with greatest change in percentage?
Good afternoon Gentlemen, I have a column of data, with a varying number of percentage values that add up to 100%, separated by "NA", i.e.
33% 33% 33% NA 25% 25% 25% 25% NA 100% NA 20% 20% 20% 20% 20% NA
Now... when I change one of the values I would like the others to even up, i.e. in the last example if I change a 20% to 50% I would like the others to change to 10%... any ideas?
I was quite a few problems using worksheetfunction.ln() to calculate % change. I decided to write more basic code to try to accomplish this but I'm getting an overflow error.
Code: DRows = WorksheetFunction.CountA(Sheets("INFO").Range("A:A")) For r = 1 To (DRows - 1) '***** -1 is bc of ln property percentchange = 0
I am not sure why the html maker didn't work so I will try and ask this without it. Please be patient. If it wasn't so confusing for me I would have figured this out already so I come to you, the experts.
I have three sheets in a work book. I am attempting to track not only the differences but the percentage of change between data on sheets 2 & 3.
Here are the cells on sheet one:
A1: Name1 B1: Place1 C1: Difference1 D1: Percentage of Change1 A2: Name2 B2: Place2 C2: Difference2 D2: Percentage of Change2
I am using Excel 2007. I have two sets of data. y-series is 58.61, 58.66, 58.71 and 58.76. x-series is 0.8313, 0.8309, 0.8305 and 0.8301.
I am trying to fit a quadratic function to this data. When I plot a curve and fit a trendline I get the coefficients for the equation ax^2+bx+c a=1.3939e-11 b=-125 c=162.5225 The plotted line seems to fit the data fairly well.
However, I want to use the linest function and I am using the formula: =INDEX(LINEST(B2:B5,A2:A5^{1,2}),1,1) I change the index column number as appropriate to get the coefficients: a=-75.23775 b=0 c=110.603763
The coefficients from linest seem to be way out. how I can get the output from linest to be the same as the trendline?
I have created a scatterplot with a trendline and I need a formula to represent the trendline so it can be applied to separate results. How I can create a formula and an R2 value?
I have a Pivot Table with fields for months and weeks. I also have a "Show Values as % Difference Field" that shows monthly or weekly % change. When I collapse the fields so that it goes from weekly to monthly (or vice versa), I have to manually change each Show Values As % Difference column. Is there a way to do this automatically or quickly?
I am trying to add columns to my Excel 2010 Pivot Table to calculate % change of sales from year to year. The field name is "Year", while the item columns in the field are 2007, 2008, 2009, 2010, and 2011. How do I add a column between the years that will calculate the % change os sales up or down from the previous year?
I have been doing some statistical anaylsis in excel and have been using trendlines within scatter charts quite a bit.
I know excel can display the equation of the line as well as the r-squared on the chart. Is there any way to get the values for the trendline to appear in a cell next to the corresponding chart data? Of course, I can simply enter the formula myself that is given on the chart, but I am wondering if there is a way to do it automatically.
I have included the data below along with the trendline value that I calculated by manually entering the formula from the scatter chart.
Code: YXTrendline Value $78.990.53$79.79 $78.730.53$79.73 $80.550.52$80.88
I need VBA to copy the values from a treadline output box on a chart to a new sheet. The macro recorder produces the code below, but I need to make the 5th line generic so that the code will apply to any workbook. The code below will not run without the "Windows("Test.xls").Activate" statement, which restricts the code to a workbook of a specifc name (Test.xls). How can I make this run for any workbook name?
Sub CopyTreadlineData() Sheets("A").Select ActiveSheet.ChartObjects("Chart 1").Activate ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select ActiveWindow.Visible = False Windows("Test.xls").Activate Sheets("Beta").Select Range("B15").Select ActiveSheet.Paste End Sub
I'm in the middle of designing a sheet that (amongst many other things) takes the equation of a graph trendline, pastes it, and calculates the various values along it. I can do it by hand, but when I try to record a macro, it doesn't register that I've highlighted the equation and hit copy. Here's the code I'm working with:
Sheets("Graphs").Select ActiveSheet.ChartObjects("Chart 1").Activate ActiveChart.SeriesCollection(1).Trendlines(1).DataLabel.Select Selection.Copy ActiveWindow.Visible = False Windows("Copy of HRA Design calculator1.xls").Activate Sheets("Binder @ max. stability").Select Range("A1").Select ActiveSheet.paste
The problem is line 4 - it can't copy because the text isn't selected.
i have a workbook that contains a series of worksheets. the workbook is a master document list. the first worksheet contains no data. the remaining worksheets are arranged so that A1 has the document number, A2 contains the document title, and A3 contains the review date. Id like to create a search macro that can search for the string entered into textbox1. if this is a number, the macro should search A1:A50 of all but the first worksheets in the workbook, and if its text, the macro should search B1:B50 of all but the first worksheets.
the macro should then select the cell containing what was searched. then id like the macro to prompt me and ask if id like to modify the reviewed date to todays date. d like to be prompted to continue searching for other records if they exist, and after that loop has finished to set the focus back to the search textbox.
i have a function in a cell (that works) to extract coefficients from a range of cells in a workbook:
VB: =INDEX(LINEST(CP25:CP27,CQ25:CQ27^{1,2}),1)}
i have variables for cp25:cp27 and cq25:cq27 already defined in my vba code. the values for these in the case i am working on are as follows (returns 110.5):
1) how to do this function in VBA only - this is part of a UDF and cannot have any helper cells 2) how to refer to 560,570,580 as a 'range'. is there a way to put these six variables into my ranges for later processing?
All of the google searches i have deal only with linear regression, taking from existing graphs, or say to just use the function i have above.
I have tried
VB:
Var = Application.WorksheetFunction.LinEst(Sheets("references").Range("CP25:CP27"), Sheets("references").Range("CQ25:CQ27^{1,2}"), 1) [COLOR=#333333][/COLOR]
but return #value! errors. when i remove the ^{1,2} portion, i do return a value but it is incorrect (returns 160), what is the correct syntax for adding in the ^{1,2}? if you do that would be fantastic, but brings me back to issue #2 in that i need to refer to my variables in the vba code and not this range (as they will eventually be going away).
