We know that using a unique weighting formula that prioritizes the most relevant time periods, exponential smoothing calculates a trend equation via the information. With **Microsoft Excel**, we can perform perfectly while computing **exponential smoothing**. **Excel** has some amazing tools and add-ins. In this article, we will demonstrate the procedures to calculate trend adjusted exponential smoothing in Excel.

**What Is Exponential Smoothing in Excel?**

Excel has an integrated smoothing approach which is **Exponential Smoothing**. We use this for trend projection, data smoothing, and forecasting. For the purpose of making informed judgments, exponential smoothing is utilized to anticipate the company volume. This method ‘**Smooths**’ the information by reducing the number of explanatory variables.

**Where Can We Get Exponential Smoothing in Excel?**

To access the exponential smoothing tool, we need to enable the **Data Analysis** tab on the Excel ribbon. The **Data Analysis** feature gives the ability to think critically regarding the information in normal language rather than needing to create laborious algorithms. To enable the **Data Analysis** tab, we have to follow the instructions down.

**STEPS:**

- Firstly, go to the
**File**tab from the ribbon.

- This will take you to the backstage menu on the
**Excel application**. - Secondly, scroll down a bit, and click on the
**Options**menu.

**Excel Options**dialog box will appear.- Next, go to
**Add-ins**and select**Analysis ToolPak**in the**Add-ins**group. - Further, choose the
**Excel Add-ins**option from the**Manage**drop-down menu. - Then, click on the
**Go**button.

- Thus, the
**Add-ins**dialog box will show up. - Consequently, check the box
**Analysis ToolPak**. - And, then, click on
**OK**to complete the procedure.

- Finally, when you go to the excel ribbon again and go to the
**Data**tab you will see the**Data Analysis**feature is now enabled in the**Analysis**category.

**Step-by-Step Procedures to Calculate Trend Adjusted Exponential Smoothing in Excel**

An **Adjusted Exponential Smoothing** is a technique that creates predictions from quantifiable past information samples by computing a weighted average of the original value and projection for the recent period and adding a trend adjustment. Let’s follow the instructions to calculate trend adjusted exponential smoothing in Excel.

**Step 1: Insert Important Information in Excel**

In the first place, we have to insert all the necessary information.

- Firstly, we put the periods in column
**B**. And we insert**10**periods of time to compute the exponential smoothing. - Secondly, insert the demand for each period.
- Thirdly, input the
**Smoothing Constant**which is**Alpha**(**α**). In our case, the**Alpha**value is**20%**or**.02**. - Fourthly, put the
**Trend Factor**which is**Beta**(**β**). In this instance, the**Beta**value is**30%**, or**.03**.

**Step 2: Calculate Exponential Smoothing Forecast**

Excel’s exponential smoothing feature is quite intuitive and straightforward. We can easily perform with a tool also with an equation or formula. First, we will see finding exponential smoothing with the excel **Data Analysis** tool.

- To begin with, go to the
**Data**tab from the ribbon. - Then, click on the
**Data Analysis**feature under the**Analysis**category.

- As a consequence, this will display the
**Data Analysis**dialog box. - Scroll down a bit and select
**Exponential Smoothing**. - Afterward, click
**OK**.

- Hence, the
**Exponential Smoothing**dialog will open up. - Now, place the
**Input Range**and**Damping factor**in the**Input**part. In our case, we take the range of**Demand**(**$C$5:$C$14**) and put**.02**as our damping factor. - Further, place the
**Output Range**in**Output options**where we want to see the result of our exponential smoothing. - Furthermore, if you wish to see the output in a chart also, checkmark the box of
**Chart Output**. - Lastly, click on the
**OK**button to finish the strategy.

- Therefore, we can see that the
**Exponential Smoothing**result is shown in our selected output range and the chart is visible. - But, there is a problem to use this as the first-period exponential smoothing shows the
**#N/A**error. Therefore, while calculating the trend we will get a**#N/A**error in all the trend values.

Accordingly, it’s better to use the formula of exponential smoothing. But there is also a slight issue that we didn’t get the accurate result of exponential smoothing, but the result will be quite similar to the accurate one. Let’s look at the instruction to calculate exponential smoothing with a formula.

- First, we take the demand value as our first-period exponential smoothing. So, we select cell
**D5**and put the simple formula into that cell.

`=C5`

- Press
**Enter**.

- Secondly, select the second cell
**D6**, and put the formula into that selected cell.

`=C5*$D$16+(1-$D$16)*D5`

- Hit the
**Enter**key to complete the process.

- Now, drag the
**Fill Handle**down to duplicate the formula over the range. Or, to**AutoFill**the range, double-click on the plus (**+**) symbol.

- Finally, you can see the result of
**Exponential Smoothing**.

- Further, we want to decrease the decimals. For this, go to the
**Home**tab on the ribbon. - Then, click on
**Decrease Decimal**on the**Number**group.

- That’s it! We can see the exponential smoothing result.

**Step 3: Compute Trend**

Now, we will calculate the **Trend**. A **Trend** is a structure in the information that demonstrates that a sequence moves through periods to comparatively usually greater values.

- Select cell
**E6**and insert the formula to calculate the trend in that cell.

`=$D$17*(D6-D5)+(1-$D$17)*E5`

- Hit the
**Enter**key on your keyboard. - The result will now display in the selected cell, along with the formula in the formula bar.

- Further, to copy the formula over the range, drag the
**Fill Handle**down. Or,**double-click**on the plus (**+**) sign to**AutoFill**the range.

- We put
**0**in the first-period trend. And other periods’ trend is resulted by using the formula.

**Step 4: Find Adjusted Exponential Smoothing**

Now, we will calculate the adjusted exponential smoothing by adding the exponential smoothing and trend.

- In the first place, select the cell where you want to see the result. We keep the first-period adjusted exponential smoothing cell blank. So we select the second-period cell.
- Put the formula of addition into that cell
**F6**.

`=D6+E6`

- Then, press the
**Enter**key on your keyboard. - Now, you will be able to see the result in the selected cell and the formula will appear in the formula bar.

- Further, to copy the formula over the range, drag the
**Fill Handle**down. Alternatively,**double-click**on the plus (**+**) sign to**AutoFill**the range.

- Lastly, we put the number as the same as the demand and exponential smoothing in our first period of adjusted exponential smoothing.
- And, that’s it! By just following the above steps we can calculate the adjusted exponential smoothing in excel.

**Step 5: Insert Chart**

Finally, to visualize the expense more often, we can insert a **Chart**. **Charts** are a popular tool for graphically illuminating data connections. We use charts to convey data that are too many or complex to be fully expressed in the text while taking up less space.

- Firstly, select the data which we need while inserting the chart. In our case, we select the
**Period**,**Demand**,**Exponential Smoothing,**and also**Adjusted****Exponential Smoothing**.

- Secondly, go to the
**Insert**tab from the ribbon. - After that, click on
**Insert Scatter (X, Y) or Bubble Chart**drop-down menu under the**Charts**group. - Choose
**Scatter with Straight Lines and Markers**which is the second-row first option of the**Scatter**.

- This will create the chart to visualize the calculation of trend-adjusted exponential smoothing more often.

**Final Output of Trend Adjusted Exponential Smoothing**

This is the final output of trend-adjusted exponential smoothing with the chart.

**Things to Keep in Mind**

- Peaks and dips in the information are rounded out as the dumping factor increases in value.
- Excel Exponential Smoothing is a really adaptable and simple to calculate approach.
- The damping factor is greater; the
**Alpha**value is less. As a consequence, the peaks and dips are rounded off most. - The damping factor is less and the
**Alpha**value is larger. The smoothing results are hence more similar to the real sample points.
