Adding Formulas
Formulas, as the name indicate are calculations that you could define in Zoho Analytics to help you create the required reports. Zoho Analytics provides a powerful formula engine to create any type of calculations required, to enable creating the required reports. Formulas are mathematical expressions that you create, which contains any combination of numbers, references of table columns, operators and functions etc. Functions are predefined mathematical formulas which are designed to perform specific well-known calculations.
Zoho Analytics supports different flavors of formulas. The following is a summary of the various types of formulas that are supported in Zoho Analytics:
- Formula Columns: These are formula types where you could add a new column to your data table, whose values are derived based on the calculation/formula defined. You can define any powerful mathematical formula which uses the table columns in combination with operators and in-built functions.
- Aggregate Formulas: Aggregate Formulas are formulas where you should use aggregate functions (SUM, AVG..) in the calculation. The result of Aggregate Formulas will not be added as another column in the base table. They will just be associated with the table on which it has been created and can be used in creating reports (Charts, Pivot Tables and Summary Views) like any other table columns.
Custom Formula
Zoho Analytics allows you to define your own powerful formulas to meet your specific reporting requirements. This enables you to easily perform from simple calculations such as addition and subtraction to a complex combination of inbuilt functions.The output of the formula added as a new column in the table is called a Formula Column. You can use these formula columns in creating reports in the same way you use other columns in a table.
Zoho Analytics provides you with a variety of inbuilt functions which are predefined mathematical formulas which are designed to perform specific well-known calculations easily. These inbuilt functions can be used in combination with the table columns and basic arithmetic operators like +, -, / and * to create your formula column.
To create and use formula columns:
- From the Explorer tab of the workspace, select the table to which you want to add the formula column.
- Select Add > Formula Column option from the toolbar or right click on a column in the table and select Add Formula > Formula Column.
- The Formula Columndialog box will open as shown below. This dialog box provides easy access to the names of the columns in your table, as well as to many of the in-built functions that are available to create formulas. A brief description of the function with syntax and an example will be displayed at the bottom of the dialog box when you hover your mouse over a function.
- In the Add Formula Column dialog box, select the columns and functions that you want to insert from the list under the Click to Insert Columns and the Click to Insert Function boxes.
For example, to build a formula column that adds particular number of days to a given date:
- Select Add Date function. You will notice that adddate() syntax appears in the Formula text box.
- In the Formula text box, position the cursor in between the parenthesis, select the date column to which you wanted to add date.
- Enter the number of days (say 10) that you want to add separated by comma.
To create a formula column with this expression, type column name in the Formula Column Name text box and then click OK. A new formula column will be created in your table as shown below.
You can edit the formula column any time by right clicking on the formula column listed in the table and clicking Edit Formula Column in the popup menu. Also refer to View/Edit Formulas to know how you could view all the formulas defined on a table and handle edition or deletion of the same.
Quick Add option for Formula Columns
Zoho Analytics provides an easy and convenient way to add formula columns which are based on a limited set of widely used functions. You can find this quick add option as follow.
- Select a column based on which you want to add the formula column.
- Click Add > Add Formula Column option on the toolbar.
- Zoho Analytics automatically identifies the data type of the column selected and displays a list of widely used pre-defined formulas which are applicable to that as shown in the screenshot below.
- On selecting the required formula from the list, Zoho Analytics applies the formula on the corresponding column and adds a new formula column, at the right end of the table.

Creating Formulas Over Formula Column
Formula columns are similar to other columns of the table. You can make use of existing formula columns while creating a new formula column, as you do with other columns of the table. Reusing existing formulas column to create new formula columns helps you create powerful formula combination, as well as eases in the maintenance of these formula structures in your workspace. Refer to the above section to know how to create formula column.
Creating Reports Using Formula Column
Formula columns can be used while creating reports as you would use a column in a table. When you create a new report over the table, in which you have added the formula column, all these formula columns will be listed in the Columns list pane on the left, which can be drag and drop to create the report. You can apply functions on the formula column, as you do for other columns, using the combo box that is displayed over the column when dropped in the design area of the report.
The following screenshot shows the Payment Date formula column listed in the columns list page:
Sharing a Formula Column
Once a Formula column is created, it behaves like any other column in a table. When you share a table, all the existing formula columns will also be shared to the user.
Note:
- The shared user will not be able to edit, delete or format the shared formulas. Also the shared user will not be able to add his own formula column over the shared table, unless the shared user is a Workspace Admin.
Aggregate Formulas
In reporting the most common data analysis that we do is to apply aggregate functions over the data (like SUM, AVG, COUNT etc.,) and analyze the same. The important aspect to be taken care in such calculations is to compute the aggregation in the context in which the function is applied to provide accurate results. Aggregate Formulas in Zoho Analytics is meant to address this need.
Aggregate Formulas are formulas that you define in Zoho Analytics which uses at least one aggregate function (SUM, AVG..) in the calculation. The output of such calculations is always a numeric value (metric). Aggregate formulas are mainly used in creating powerful reports. These formulas can be used in Charts, Pivot Tables and Summary View report types in Zoho Analytics.
- The result of an Aggregate Formula is always a numeric value.
- Aggregate Formulas will not be added as another column in the base, it is associated with, like Formula Column. But it will be available for report creation when you create a report over the table (listed as part of the columns list).
- The value of an aggregate formula will be computed for each data point that is displayed in the report in which it is used (i.e., the result is not just a single value). This makes it very powerful.
- An aggregate formula can be constructed in a similar way as that of a Formula Column.
Zoho Analytics offers a range of in-built aggregate functions which can be used as part of the Aggregate Formulas. You can construct the formulas using these in-built aggregate functions combining it with the basic arithmetic operators like +, -, / and *.
Creating Aggregate Formulas
To create an aggregate formula:
- Select Add > Aggregate Formula option from the toolbar as shown below.
- The Add Aggregate Formula dialog box will open as shown below. This dialog box provides easy access to the names of the columns in your table, as well as to all the in-built functions that are available for you to create the formula. A brief description of the function with syntax and an example will be displayed at the bottom of the dialog box when you hover your mouse over a function.
- In the Formula Name text box, type the name that you want to give to the formula.
- Select the data type of the aggregate result of the formula, using the DataType drop down menu. The data type should only be a Numeric value, hence the possible types are Number, Positive Number, Decimal Number, Currency and Percent.
- The Associated Table field provides the name of the table to which this formula is associated with. This will be automatically set with the name of table for which you are creating this aggregate formula.
- In the Formula text area provide the actual formula. You can select the columns and functions that you want to insert into the formula from the list from the Click to Insert Columns and the Click to Insert Function boxes.
Note: You can also insert columns from related tables joined through Lookup Column. The drop-down lists all the parent table associated with the base table. Select the required table, the columns in this table will be listed below. You can insert this in the formula by clicking.
- For example, to apply an aggregate formula to calculate % Profit the formula could be something like (SUM("SALE")- SUM("COST"))/SUM("COST")*100 as shown in the screenshot below.
- Click OK.
The result of Aggregate Formulas will not be added as a column in the base table. It will be listed in the column panel while creating reports. You can access (view) or edit it by clicking Add > Edit Formulas in the toolbar. Viewing & Editing Formulas is discussed in the next section.
In-built Aggregate Functions
While you create an aggregate formula you can use a wide range of powerful inbuilt functions that are supported by Zoho Analytics. You can use the inbuilt functions, that are applicable while creating Formula Columns, even when you create an Aggregate formula, provided it meets the required conditions for an Aggregate formula. There are also specific functions which are more relevant & applicable for creating Aggregate formulas. The following table describes these functions:
FUNCTION | DESCRIPTION |
Sum - sum(numeric_column) | Returns the sum of the 'numeric_column' |
Avg - avg(numeric_column) | Returns the average of the 'numeric_column' |
Min - Min(numberic_column) | Returns the minimum of the 'numeric column' |
Max - max(numeric_column) | Returns the maximum of the 'numeric_column' |
Count - count(column) | Returns the number of rows (values) in the given column |
Stddev - stddev(numeric_column) | Returns the standard deviation of the 'numeric_column' |
Variance - variance(numeric_column) | Returns the variance of the 'numeric_column' |
Distinct Count - count(distinct(column)) | Returns the distinct number of values (rows) in the given column. |
SumIf - sumif(condition, expr1, expr2) | Returns the sum of expr1, if condition is true. Else it will return the sum of expr 2. The expr1 and the expr2 can be an expression or just a numeric column. The expr2 is an optional argument. Example: sumif(Region = 'East, Sales, 0) will return the sum of values in the sales column for all the records which matches the value East in the Region column. Else it will return 0. |
AvgIf - avgif(condition, expr1, expr2) | Returns the average of expr1, if condition is true. Else it will return the average of expr 2. The expr1 and the expr2 can be an expression or just a numeric column. The expr2 is an optional argument. Example: avgif(Region = 'East, Sales, 0) will return the average of values in the sales column for all the records which matches the value East in the Region column. Else it will return 0. |
CountIf- countif(condition) | Returns the number of rows (records) that satisfies the condition. Example: countif(Region='East') will return the number of rows (records) in the table which matches the value East in the Region column. |
YTD -YTD(AggExpr,Date_Col) | Year-to-date is a period, starting from the beginning of the current year and ends at the current day.
Arguments: Example: YTD(Sum(sales), OrderDate) will return the Sum of sales for the current Year till current day, based on date column 'OrderDat |
QTD - QTD(AggExpr,Date_Col) | Quarter-to-date is a period, starting from the beginning of the current quarter and ends at the current day.
Arguments: Example: QTD(Sum(sales), OrderDate) will return the Sum of sales for the current Quarter till current day, based on date column 'OrderDate'. |
MTD - MTD(AggExpr,Date_Col) | Month-to-date is a period, starting from the beginning of the current month and ends at the current day.
Arguments: Example: MTD(Sum(sales), OrderDate) will return the Sum of sales for the current Month till current day, based on date column 'OrderDate'. |
Creating Aggregate Formula over existing Aggregate Formulas
Zoho Analytics enables you to build aggregate formulas using existing aggregate formulas. Reusing existing formulas to create new aggregate formula helps you create powerful formula combination, as well as eases maintenance of this formula structure in your workspace.
When you create a new aggregate formula, existing formulas will be listed in the Click to Insert Columns box along with other columns. All the aggregate formulas will be indicated in brown with the ∑ symbol. You can insert these formulas into your new formula definition by clicking them, as you do for the other columns in the table.
For example, Let's assume that you have already calculated profit percentage and total cost and you want to calculate total profit gained. Then you can use the existing aggregate formulas to calculate total profit gained. The formula could be something like ("Total Cost" * "Profit") / 100.
Creating Reports using Aggregate Formulas
Aggregate formulas can be used while creating all reports (charts, pivot tables and summary views) as you would use a column in a table. When you create a new report over the table, in which you have added the aggregate formula, all the formulas will be listed in the Columns list pane on the left, which can be drag & dropped to create the report.
The following screenshot shows the % Profit aggregate formula, that we added, listed in the columns list page. All the aggregate formulas will be indicated with an icon which contains the symbol.
From the Explorer tab of the workspace, select the table to which you want to add the aggregate formula.
Aggregate formulas can be used in the report as you use any other data columns in the table. The value of the aggregate formula will be computed for each data point that is displayed in the report in which it is used (i.e., the result is not just a single value). In the chart shown in the screenshot below, the percentage of profit (%Profit) is plotted against the Year. As you see, the value of the Profit percentage is calculated for each year and plotted in the graph.
When you use an Aggregate formula in a report, you will not be able to apply other functions on the formula (as you do for other columns). The function will always be selected as 'Actual' and cannot be modified.
Sharing Aggregate Formulas
With respect to sharing and collaboration, Aggregate Formulas behave similar to how a column in a table behaves. When you share a table, all the aggregate formulas that are created over the table will be also shared to the user to whom you are sharing the table. Hence the shared user will be able to use these formulas while creating any report over the data table.
Note:
- The shared user will not be able to edit, delete or format the shared aggregate formula, but can just use it in report creation. Also the shared user will not be able to add his own Aggregate formulas over the shared table, unless the user is a Workspace Admin.
View/Edit Formulas
Zoho Analytics allows you to view, edit, format and delete all the formulas defined for a table through the Edit Formula option. You can view & edit both Formula Columns and Aggregate Formulas using this option. To view/edit existing Formula Column or Aggregate Formulas:
- Select the required table.
- Select Add > Edit Formulas option from the toolbar.
- The Edit Formula dialog box with a list of all the formulas associated to the table will open as shown below:
- Click Edit link next to the formula that you wish to edit.
- The Edit Aggregate Formula/Formula Column(depending on the type of formula) dialog box will open, you can modify the existing formula the same way as you would create a new formula.
- Edit Formula: You can edit the constructed formula using the Edit link provided next to the corresponding formula.
- Delete Formula:You can delete an existing Formula any time from the table using the Remove link provided next to the corresponding formula.
- Format Formula:You can change the format of the Formula result, like alignment, decimal places, date format, currency symbols etc., depending on its data type of the formula using the Format link provided. It's similar to how you format a data column. Refer here to know how to format a column.
