Data Table in Excel

What is a Data Table in Excel?

Data tables in excel are used to compare variables and their impacts on the result and overall data, data table is a type of what-if analysis tool in excel and is present in the data tab in the what-if analysis, this tool asks for a row input and a column input table to make a data table and the impact is calculated by one variable or two-variable data table.

Types of Data Table in Excel

1. One-Variable Data Table
2. Two-Variable Data Table

1) One-Variable Data Table in Excel

The basic requirement for the data table is to create a base or testing model. You need to instruct your data table which formulas from your data model you want to test. The one-variable data table is best suited when you want to see how the eventual result changes when you change the input variables.

Example

Mr. Murali running a factory named ABC Pvt Ltd. In addition, he is estimating the revenue for the year 2019. Below table shows the revenue for the year 2018 and estimated revenue at different increment levels.

The above table shows revenue for the year 2018 is 15 lakh USD and expecting a minimum growth of 12% for the next year. Now, Murali wants a data table, which shows the revenue growth table at different increment rates. He wants the scenario table in the below format.

Apply Data Table technique to get the desired results.

Step 1: Create this data table format in an excel file. The estimated revenue for 2019 is shown in the cell B5.

Step 2: Select the cell D8 and give a link to the cell B5 (estimated revenue cell). Now the cell D8 showing the estimated revenue for 2019.

Step 3: Select the range from C8 to D19.

Step 4: Click on Data Tab > What-if-Analysis > Data Table

Step 5: Data Table dialogue box will come up. In the Column Input Cell, select the cell B3 (which contains the minimum growth rate percentage).

Since it is a one-variable data table leave out Row Input Cell. The reason why we have selected the cell B3 because based on the different growth rates we are going to create the scenarios. Now, the data table understands at 12% the estimated revenue is 15 lakh USD. Similarly, it will create scenarios for 12.5%, 13.5%, 14.5% and so on.

Step 6: Click on ok to create different scenarios.

Now the range D9:D19 showing some new values. From the table, it is very clear that @12.5% growth rate estimated revenue will be 16.875 lakh USD and @14.5% estimated revenue would be 17.175 lakh USD and so on.

This is how one variable data table example works. You can show this in a chart as well.

2) Two-Variable Data Table in Excel

We can use a two-variable data table to analyze scenarios if two variables change at a time. For this, we need two ranges of possible input values for the same formula. That means here it will affect both Row & Column.

Example

Now go ahead and examine this two-variable data table example.

Mr. Murali was thinking of revenue growth at different rates. Similarly, he is planning to give discounts to his customers to increase sales opportunities.

The below table shows Murlali’s plan to increase the growth in the next year. He wants to estimate the revenue at different growth levels with different discount rates.

Step 1: Create an above Data table in excel.

Step 2: In the cell, B6 put the below formula to calculate eventual revenue after the discount.

=B2 + (B2*B3)-(B2*B4)

First, it will add the growth rate from the previous year and deduct the discount rate.

Cell D9 contains the reference to the cell B6.

Now, the above table shows the possible growth rate from D10 to D18 (Column Value) and a possible discount rate from E9 to J9 (Row Value).

Step 3: Select the range D9:J18.

Step 4: Click on Data Tab > What-if-Analysis > Data Table

Step 5: Data Table dialogue box will come up. In the Column Input Cell, select the cell B3 (which contains the minimum growth rate percentage) and in the Row Input Cell, select the cell B4.

Together with the formula in cell D9 (refers to cell B6), Excel knows that it should replace cell B4 with 2.5% (cell E9), and cell B3 with 12.5% (cell D10) and so on for others as well.

Step 6: Click ok.

Now, if Murali is aiming at a 13.5% growth with a 2.5% discount rate then the revenue will be 16.65 lakh USD. If Murali aiming at achieving 17 lakh USD, next year’s maximum discount he can give is, 3% and it can give him the revenue of 17.025 lakh USD.

This is how helpful is the Data Table to create different scenario models to assist the decision-making process.

Important Notes:

• A Data Table will show you how by changing the certain values in your function you can change the result of the formula.
• It stores the results of many variable scenarios in one table so that you can finalize the best scenario for your business or project. The results are written in the table format.
• It is an array formula, which allows multiple calculations in a single location.
• Once you have calculated the values through the data table, you cannot undo the action (Ctrl + Z). However, you can manually delete all the values from the table.
• You are not allowed to modify a single cell in the data model. Because it is an array, you have to delete everything.
• It would be so confusing to select the Row input cell and the column input cell. You need to select the cells properly to get accurate results.
• Data table in excel does not need to be refreshed all the time, unlike the pivot table.
