The Calculated Column Action allows you to use formulas to transform your data. You can either use one of our guided formulas or write your own formula using the Custom formula option. When adding a Calculated Column, you’re automatically prompted to choose a formula type.
Note: If you aren’t seeing a formula type you expect to see for an existing column, check the column’s data type. Some formulas are only available for numeric columns.
Tip! When dividing integers, be sure to multiply the top value by 1.0 to convert your results to a decimal. For example:
(1.0 * "Count of Clicks")/"Ad Cost"
When selecting a Guided Formula, you’re prompted to select values for each required field. There’s also additional text to help you decide which column to choose or what value to input for each field. No need to worry about the syntax–we handle it for you.

Single row operations
Add a numerical value to a column. If you want to add a column to another column, you’ll need to use a Custom formula.
Easily divide one column by another in your result set to get a ratio. Integers are auto-converted to decimals to ensure decimal accuracy.
First choose a column for the numerator, then choose a column for the denominator.
Create Link with Title
Use a text column and a URL column and generate a Markdown link that’s clickable from your Table chart, using the text column as the link title.
Useful for creating short, easily parsable links.
Calculate the amount of time between two dates. Choose which time unit the value is calculated in: days, weeks, months, etc.
Divide a column by a set value. If you want to divide a column by another column, you’ll need to use a Custom formula.
Select a specific part of a string, where that substring is added to a new column. Choose the starting index (1 being the first letter), then specify a length or leave it empty to include all characters to the end of the string.
Specify decimal precision (i.e., number of decimal places), useful for force-formatting currency. Format returns a string, not an integer. Therefore, it is best used in table charts or Single Value charts.
Multiply a column by a value. If you want to multiply a column by another column, you’ll need to use a Custom formula.
Round is used to round to a specific number of decimal places.
Note: You cannot round a number to a higher decimal precision than it already has. For example, you cannot round the integer 10 to have two decimal places.
Subtract a value from a column. If you want to subtract a column from another column, you’ll need to use a Custom formula.
Total Column Sum
Create a new column where each value is a sum of the values in its row.
Multi row operations
Create a new column with an aggregation value of another column. Choose from AVERAGE, COUNT, MAX, MEDIAN, MIN, or SUM.
Useful for applying calculations to a column that involve an aggregated value. For example, use the SUM aggregation then add another Calculated Column and use Column Ratio to determine a column’s value percentage of the total column.
Access data from a previous row in an existing column. Row offset defines the number of rows back from the current row to use.
Useful for comparing the value of a row with the value of the previous row.
Generate a series of averages of your data to create a smooth trend line. Trailing rows is the number of previous rows to include in each row’s average.
Determines the percent change between the current and previous row.
Determines the percentile of each value in a numeric column. For example, a value is at the 50th percentile if half of the values in the column are less than or equal to it.
Ratio of Total
Displays each row’s value as a ratio of the column sum (i.e., the row’s value divided by the column’s total sum).
Cumulative sum of all previous results of a column (i.e., row1, row1+row2, row1+row2+row3, etc.).
Perform basic calculations on your column, or combine one or more of functions as needed. SQLite functions are also supported. See the SQLite documentation for the full list of core functions, aggregate functions, window functions, and date and time functions available.
Want to use a column from your result set in a Custom formula? Just make sure to wrap the column name in double quotes (i.e.,
"column name"). As you type the column name, it will appear as an auto-complete option if it’s a valid column to use.
Want to use a static string in a Custom formula? Wrap the string in single quotes (i.e.,
There are some auto-complete functions that appear when creating a Custom formula. The format for these functions is conveniently shown but the values must be manually typed into the field–except for column names, which have an auto-complete feature.
The following functions are available as auto-complete functions:
- dateadd(values, amount, unit)
- datediff(values, values, unit)
- datepart(values, unit)
- datesub(values, amount, unit)
- format(values, format_string)
- moving_avg(values, sample_size)
- power(base, exponent)
Note: Some of the above functions are now Guided Formulas! We recommend using Guided Formulas, if available.
While there are many SQLite functions that aren’t pre-built for Calculated Columns, we do support them. You can manually input other SQLite functions into the Custom formula field, and they’ll work as expected.
Here are some common functions you might use:
acos, asin, atan, atn2, atan2, acosh, asinh, atanh, difference, degrees, radians, cos, sin, tan, cot, cosh, sinh, tanh, coth, exp, log, log10, power, sign, sqrt, square, ceil, floor, pi
replicate, charindex, leftstr, rightstr, ltrim, rtrim, trim, replace, reverse, proper, padl, padr, padc, strfilter
stdev, variance, mode, median, lower_quartile, upper_quartile
In the formulas below, units can be one of the following: day, month, year, hour, minute, second, quarter (
datepart() only), dayofyear (
datepart() only). For more details on these date functions, check out the SQLite date and time functions page.
