*In this short tutorial, you will learn how to quickly calculate a simple moving average in Excel, what functions to use to get moving average for the last N days, weeks, months or years, and how to add a moving average trendline to an Excel chart.*

In a couple of recent articles, we have taken a close look at calculating average in Excel. If you've been following our blog, you already know how to calculate a normal average and what functions to use to find weighted average. In today's tutorial, we will discuss two basic techniques to calculate moving average in Excel.

Generally speaking, **moving average** (also referred to as *rolling average*, *running average* or *moving mean*) can be defined as a series of averages for different subsets of the same data set.

It is frequently used in statistics, seasonally-adjusted economic and weather forecasting to understand underlying trends. In stock trading, moving average is an indicator that shows the average value of a security over a given period of time. In business, it's a common practice to calculate a moving average of sales for the last 3 months to determine the recent trend.

For example, the moving average of three-month temperatures can be calculated by taking the average of temperatures from January to March, then the average of temperatures from February to April, then of March to May, and so on.

There exist different types of moving average such as simple (also known as arithmetic), exponential, variable, triangular, and weighted. In this tutorial, we will be looking into the most commonly used **simple moving average**.

Overall, there are two ways to get a simple moving average in Excel - by using formulas and trendline options. The following examples demonstrate both techniques.

A simple moving average can be calculated in no time with the AVERAGE function. Supposing you have a list of average monthly temperatures in column B, and you want to find a moving average for 3 months (as shown in the image above).

Write a usual AVERAGE formula for the first 3 values and input it in the row corresponding to the 3^{rd} value from the top (cell C4 in this example), and then copy the formula down to other cells in the column:

`=AVERAGE(B2:B4)`

You can fix the column with an absolute reference (like $B2) if you want to, but be sure to use **relative row references** (without the $ sign) so that the formula adjusts properly for other cells.

Remembering that an average is computed by adding up values and then dividing the sum by the number of values to be averaged, you can verify the result by using the SUM formula:

`=SUM(B2:B4)/3`

Supposing you have a list of data, e.g. sale figures or stock quotes, and you want to know the average of the last 3 months at any point of time. For this, you need a formula that will recalculate the average as soon as you enter a value for the next month. What Excel function is capable of doing this? The good old AVERAGE in combination with OFFSET and COUNT.

=AVERAGE(OFFSET(*first cell*, COUNT(*entire range*)-*N*,0,*N*,1))

Where *N* is the number of the last days / weeks / months/ years to include in the average.

Not sure how to use this moving average formula in your Excel worksheets? The following example will make things clearer.

Assuming that the values to average are in column B beginning in row 2, the formula would be as follows:

`=AVERAGE(OFFSET(B2,COUNT(B2:B100)-3,0,3,1))`

And now, let's try to understand what this Excel moving average formula is actually doing.

- The COUNT function COUNT(B2:B100) counts how many values are already entered in column B. We start counting in B2 because row 1 is the column header.
- The OFFSET function takes cell B2 (the 1
^{st}argument) as the starting point, and offsets the count (the value returned by the COUNT function) by moving 3 rows up (-3 in the 2^{nd}argument). As the result, it returns the sum of values in a range consisting of 3 rows (3 in the 4^{th}argument) and 1 column (1 in the last argument), which is the latest 3 months that we want. - Finally, the returned sum is passed to the AVERAGE function to calculate the moving average.

As you probably noticed, the table in this example contains data for only 12 months, and yet the range B2:B100 is supplied to COUNT, just to be on the save side :)

If you want to calculate a moving average for the last N days, months, years, etc. in the same row, you can adjust the Offset formula in this way:

=AVERAGE(OFFSET(*first cell*,0,COUNT(*range*)*-N*,1,*N*,))

Supposing B2 is the first number in the row, and you want to include the last 3 numbers in the average, the formula takes the following shape:

`=AVERAGE(OFFSET(B2,0,COUNT(B2:N2)-3,1,3))`

If you have already created a chart for your data, adding a moving average trendline for that chart is a matter of seconds. For this, we are going to use **Excel Trendline** feature and the detailed steps follow below.

For this example, I've created a 2-D column chart (*Insert tab* > *Charts group*) for our sales data:

And now, we want to "visualize" the moving average for 3 months.

- In Excel 2013, select the chart, go to the
*Design tab*>*Chart Layouts*group, and click*Add Chart Element*>*Trendline*>*More Trendline Options*…

In Excel 2010 and Excel 2007, go to

*Layout*>*Trendline*>*More Trendline Options*.**Tip.**If you do not need to specify the details such as the moving average interval or names, you can click*Design*>*Add Chart Element*>*Trendline*>*Moving Average*for the immediate result. - The
*Format Trendline*pane will open on the right-hand side of your worksheet in Excel 2013, and the corresponding dialog box will pop up in Excel 2010 and 2007.On the

*Format Trendline*pane, you click the Trendline Options icon, select the**Moving Average**option and specify the moving average interval in the**Period**box:

- Close the Trendline pane and you will find the moving average trendline added to your chart:

To refine your chat, you can switch to the *Fill & Line* or *Effects* tab on the *Format Trendline* pane and play with different options such as line type, color, width, etc.

For powerful data analysis, you may want to add a few moving average trendlines with different time intervals to see how the trend evolves. The following screenshot shows the 2-month (green) and 3-month (brick red) moving average trendlines:

Well, that's all about calculating moving average in Excel. The sample worksheet with the moving average formulas and trendline is available for download - Moving Average spreadsheet. I thank you for reading and look forward to seeing you next week!

Hi,

I have read through several different articles looking for an answer to my problem, got lots of great tips but nothing defiant that helps me now.

Could you please help me on this? I’m trying to create a formula that adds the total amount for a particular supplier that is more than 30 days & in another cell a formula that is more than 60 days, etc…

I have the dates of invoices in column A, supplier’s names in column B and Total value in column C.

Any help would be appreciated, have spent days on this & to no avail. Thanks

Hi Kay,

I think you can use the SUMIFS function. For example, to find the total for supplier "John" for orders made more than 30 days ago, you can use the following formula:

=SUMIFS(C2:C100, B2:B100, "john", A2:A100,"< "&TODAY()-30)

For the detailed explanation of SUMIFS' arguments and more formula examples, please see How to use Excel SUMIFS and SUMIF with multiple criteria.

Hi,

I have some daily data, with column A having dates and column B having values. I want to calculate the average of the values occurring between two specific dates, for instance between 1/1/2016 to 2/15/2016. How would I be able to do that?

Hi,

I have 1000 numbers starting from 1 to 1000. i want average for every 3 numbers. say from 1 to 3 it should be 2. now my next number will be 4 to 6 then 7 to 10 and so on up to 1000 numbers.

If i use average function then it will do average for 1 to 3 then 2 to 4 then 3 to 5. it is not meeting my requirement.

please help me to solve this case.

Hi nikhil,

I can help you in this...you have to use indirect function to achieve this task

You can use average (indirect ("b"&rows (b$1$:b1)*3-2&":"&"b"&rows(b $1$:b1)*3))

To calculate average for column b for every 3 sets of numbers

✌

I have 2 rows, 1st row 2015 sales Jan -Dec (per month),

2nd row 2016 sales Jan - Dec (per month). I want to do a running average for 2016 vs 2015 (2016/2015=%). example; 2016 Jan vs 2015 Jan = %, as i add the next months sales i would need 2016 Jan + Feb vs 2015 Jan + Feb = % , and so on. Is this possible?

Hi .. I really liked the way it has been explained and was able to do in in a minute.. I also liked your website and will follow it regularly..

I was working with a e excel file where i required to make a moving average of last 2 months data which were in different column i.e(D3:G2)

Can you please let me know what modification is required in the formula so that i can make it work to calculate the same..

Rishabh

Hi Rishabh,

Thank you for your feedback. Assuming that you need a moving average for the last 2 numbers in the same row, you can adjust the formula in this way:

=AVERAGE(OFFSET(D3, 0, COUNT(D3:Z3)-2,1,2))

Where D3 is the first number in the row, and 2 is the number of the last N months to be included in the average.

Wow.. Thank you so much Svetlana :)

you made my day !!

Hi,

similar to CAGR which calculates compound annual growth rate in values, is there a formula for calculating the same growth between months. viz, Jan to June of the same year

Hii,

I wanted to track facebook likes on my page on daily basis. Like i want to compare today's likes with previous day's average, whether its hike or less.

sir / mam , i want to calculate ratio of employees on the basis of "INTIME"

so is there any specific formulas .please help!

thank you.

Your example 3 above (Get moving average for the last N values in a row) worked perfectly for me if the whole row contains numbers. I'm doing this for my golf league where we use a 4 week rolling average. Sometimes the golfers are absent so instead of a score, I will put "ABS" (text) in the cell. I still want the formula to look for the last 4 scores and not count the "ABS" either in the numerator or in the denominator. How do I modify the formula to accomplish this?

Yes, I did notice if cells were empty the calculations were incorrect. In my situation I am tracking over 52 weeks. Even if the last 52 weeks contained data, the calculation was incorrect if any cell prior to the 52 weeks was blank.

I'm trying to create a formula to get the moving average for 3 period, appreciate if you can help pls.

I want to do an hourly moving average of data that has a different number of observations for each hour (2 to 6 observations).

Can you help?

Hi, I am impressed with the vast knowledge and the concise and effective instruction you provide. I too have a query which I hope you can lend your talent with a solution as well.

I have a column A of 50 (weekly) interval dates. I have a column B next to it with planned production average by week to complete target of 700 widgets (700/50). In the next column I sum my weekly increments to date (100 for example) and recalculate my remaining qty forecast avg per remaining weeks (ex 700-100/30).

I would like to replot weekly a graph starting with the current week (not the beginning x axis date of the chart), with the summed amount (100) so that my starting point is the current week plus the remaining avg/week (20), and end the linear graph at end of week 30 and y point of 700.

The variables of identifying the correct cell date in column A and ending at goal 700 with an automatic update from today's date, is confounding me.

Could you help please with a formula? (I've been trying =IF logic with =Today and just not solving it.)

Thank you

Please help with the correct formula to calculate the sum of hours entered on a moving 7 day period. For example. I need to know how much overtime is worked by an individual over a rolling 7 day period calculated from the beginning of the year to the end of the year. The total amount of hrs worked must update for the 7 rolling days as I enter the overtime hours in on a daily basis

Thank you

I am looking for something very similar! I am looking for the last 6 months! I'm so stumped!

Hello Everyone,

Is there a way to get a sum of a number for the last 6 months?

I want to be able to calculate the sum for the last 6 months every day. So ill need it to update every day.

I have an excel sheet with columns of every day for the last year and will eventually add more every year.

any help would be greatly appreciated as I am stumped!

Hi, I have a similar need. I need to create a report that will show new client visits, total client visits and other data. All of those fields are updated daily on a spreadsheet, I need to pull that data for the previous 3 months broken down by month, 3 weeks by weeks, and last 60 days. Is there a VLOOKUP, or formula, or something I could do that will link to the sheet being updated daily that will also allow my report to update daily?

Hi,

Is there a way to create a spreadsheet with a formula to average 12 rolling weeks that I can also code to always put my new info in as the current week and have the data shift it's cells down by one and replace the last (or 12th) cell of data thus giving me a new rolling 12 week average?

Hi,

I have a series of data going from cell B2 onwards, where B2 is the most recent. Every month I add a new column with the latest month's value. How can I create a formula which will take the average of the last x months and which will automatically take the new value I have inserted? It seems similar to the solution provided above with taking the moving average of the last N values, but I cannot seem to tailor the formula to this situation. Please help :)

Thank you!

Hello Kiran,

The second part of this tutorial shows how to display the moving average in a graph by using the Trendline Options. If you are looking for something different, please clarify.

Thanks for neat math and good explanation.

Can we refine the formula with dividend adjusted? That reflects in price on record dates but NOT accounted in calculation.

Hello,

I am interested in creating a performance report, I will try to explain what I am looking for using only 1 row.

If cell 1A represents the first day of the month and cell 1AE represents the 31st day of the month with the total number of units sold entered into each day. Then my data in cell 1AF would equal the sum of sold units for the entire month ie. =sum(A1:AE1). My inquiry is for the following cell 1AG. I would like this cell to contain a projected total for the month running. I thought an average would work but it needs to take into consideration the remaining days left to sell. So if a person has sold 5 units on day 20 then an average based on 30 days would not be a valid projection. It would need to take the remaining 10 days as part of the equation. Not sure if this is even possible but in reading your previous comments I think if it can be done you guys would know how to do it. Thanks in advance for any help you can provide.

I'm tracking numbers for a Skeet League. Calculating moving average for their last 20 scores. The names entered down (each person has their own row), and scores recorded daily in columns. Sometimes people are absent, so we leave that blank for that person on that date. So moving average gives us an incorrect number, because it uses the "0" value????

Hello, Guy,

To include a condition to your formula (">0"), try using AVERAGEIF instead. You will find formula examples in this article.

i want to calculate average revenue increase for current..if trading starts in feb then i want avg rev inc value for Mar,apr ,may,jun,jul..below is my data

I'm trying to get a 52 weekly moving(rolling) average on a column of figures that is adjusted weekly. This avg needs to be recalculated with every weeks new data. Example net payroll/gross sales = a trackable percentage. Every week new data is entered and then needs recalculated. Can you help me with a formula for this. I'd be eternally grateful!!

I used the formula provided in example 2 and it returned a value. But, the value doesn't match what I get when I manually highlight the same cells and check the average at the bottom of Excel. Also, as I add new data at the bottom of my column, the average isn't updating. (I have the auto-calculate option turned on in Excel)

Any help on this?

Maximum of moving average.

I have a list of data (>100 rows) and am trying to find the maximum 3-day average out of the list. So far, I am only able to populate a new column with the moving 3-day AVERAGE, and then use the MAX function to determine the maximum value.

Is it possible to do this without having to create an additional column?

I have a range of numbers: B2:B6. I would like to get the average of the last 3 numbers >1.

B2 1

B3 2

B4 4

B5 6

B6 1

B7 1

Result = 4 (B3 : B5)

I know how to average >1, which is the AVERAGEIF ">1" function. But please help me with how to address the range of last three figures >1 in a range.

Thanks.
