# Understanding Inventory Forecasting in Excel Excel is widely used amongst the entire global population for keeping a record of different types of statistical and tabular data. This has eased out the hard work associated with manual data handling processes, especially in sectors like large-scale business finances, stock reports, sales and interest returns and other financial and logistic aspects. Moreover, by using an Excel worksheet and the inbuilt tools along with the formulas of the compiler, one can have an access to thousands of different mathematical and analyzing methods, most of which are so complicated that a normal human brain stops perceiving the steps clearly.

However, the repetitive and the complex data analysis, which comes in handy with Excel, has been made easier by Excel’s inbuilt forecasting and regression tool. We have often heard about the term forecasting in our daily days, especially when we turn on our television channels to the news.

Let’s have an idea about the word forecasting and its associated aspects that have made the regression analysis quite smoother for the people.

## What is forecasting?

Forecasting is a technique by which a group of data can be predicted while using the past and present values. When we are applying the concept to an Excel worksheet, we deal with two types of variables: the external variable whose value is independent, and the internal variable, which is dependent on other ones.

Usually, the methods of forecasting and prediction are overlapping and the combined effect is implemented using the Excel regression tool.

Now, forecasting can be done on various types of data like revenue, interest rates, stock details, and many such sectors. The most important and frequently used forecasting technique is on the inventory lists.

## What is inventory forecasting in Excel?

By the term “inventory”, we mean the managerial analysis of different stocks of materials. This particular term primarily resonates with the large-scale business that involves stock sales and income.

The stock is an important parameter that has to be recorded daily since a large number of other factors are dependent on it. This is the reason why forecasting is used on the inventory lists.

Inventory forecasting means to predict the stock values based on some intrinsic parameters and therefore maintaining the business and also the customers.

Excel has looked up to this matter and introduced its inventory forecasting technique, which enables large-scale businesspeople to have a control over their inventories records.

## How to create an inventory forecast Excel?

As you already know that inventory forecasts in Excel will follow a regression format, so the entire process is done on an inbuilt platform.

1. In a spreadsheet, you will have to enter data in two different columns under categories, which closely resonate with each other. For example, time and sales are two categories that are directly linked to each other. The choice will simply help you to obtain a future value.
2. Now comes the selection part where you will have to select both the columns.
3. After selecting, follow the steps as described:
Data tab > forecast group > forecast sheet
4. Now you will have to choose either a line or a column graph for the analysis part in the forecast sheet dialog box. This graphical representation will let you know the futuristic plans.
5. The forecast end box will appear where you will have to enter the pick and end date.
6. Once step 5 is done, click on the forecast button.

## Formulas related to forecasting the data

If you want to generate a forecast of your inventory data, then you will need certain formulas for the same. Here are some of the basic formulas that you will need:

1. FORECAST.ETS calculates the forecast of the selected columns
2. FORECAST.ETS.CONFIT calculates the columns having a confidential interval amidst them.
