A Pivot Table Calculated Field is a way of writing formulas within Pivot Tables. This is because it's not possible to write formulas as you normally would within Pivot Tables. Hence, if you write something along the lines of =A2+B2 you'll get an error. This is because the structure of Pivot Tables is quite difference from the normal way a spreadsheet is arranged. As a result you need to use Calculated Fields, which are designed for use within a Pivot Table, should you want to use Pivot Table data in formulas.

So if you want to calculated percentage of two columns in a Pivot Table or add a formula to a Pivot Table to do something else, Calculated Fields will be the answer you're looking for.

First, **add all the normal columns that you would like displayed** in the Pivot Table. In other words the fields that are not calculated. You don't have to include the fields that you will use in your Pivot Table formula.

Next, click the **PivotTable Analyze**. You can find this on the ribbon at the top of the screen.

After that, in the Calculations section, click on the **Fields, Items and Sets** drop down menu.

Select **Calculation Field**

The next thing we need to do is to enter a formula that will calculate the amount of profit. To do this we will subtract the expenses from the amount received. As a result we will see how much money we really made.

You should now see the Insert Calculated Field box.

In the **Name Box** type **Profit**. Then, in the Formula box enter following formula.

**=Received+Expense**

You can double click on the name of the column header, listed in the fields section, that you want to add to the formula.

Click **Add** to add the Calculated Field to the Pivot Table field list.

Now, look in the PivotTable Fields box and you will see that the Profit field is added to the Pivot Table Fields list. Also, the Profit field has been added to the Pivot Table.

Then, if necessary, right click on the Sum of Profit in the Pivot Table and select Number Formatting. Then, **change the format of the Profit field** in the Pivot Table **to Accounting**.

You may already know how to calculate the percentage of two columns but how to calculated percentage of two columns in a Pivot Table? You again would use the Pivot Table Calculated Field feature to create the formula you need.

**Click any cell in the Pivot Table** that you want to add the Calculated Field to.

Click **Fields, Items & Sets** from the Ribbon, select **Insert Calculated Field. **

In the Insert Calculated Field box **enter Profit %** in the name box and enter **=Profit/Received**

Finally, **Right Click in the Pivot Table anywhere in the Sum of Profit %** Column.

Choose **Number Formatting**.

Double click **Percentage**.

Change the Headings at the top to something a little more appetising, change colours using the Design tab and your Pivot Table should look beautiful.
