Calculated fields
Calculated fields let you define a formula that computes a value from other field answers in the same form. The result is shown to the respondent as a read-only value and is written to Attio on submission.
Calculated fields are a Pro plan and above feature.
What they are for
Common uses include:
- Calculating a total price from quantity and unit cost fields
- Computing a score or rating from multiple numeric inputs
- Deriving a value (e.g. a discount amount) from a conditional expression
- Concatenating name parts or building a reference string
Referencing other fields
Reference other fields in your formula by their Attio attribute slug, wrapped in double curly braces:
{{quantity}} * {{unit_price}}The autocomplete in the formula editor suggests available field slugs as you type {{.
Supported functions
Arithmetic operators
| Operator | Description |
|---|---|
+ | Addition |
- | Subtraction |
* | Multiplication |
/ | Division |
Numeric functions
| Function | Description |
|---|---|
sum(a, b, ...) | Sum of all arguments |
avg(a, b, ...) | Average of all arguments |
min(a, b, ...) | Smallest value |
max(a, b, ...) | Largest value |
round(n, decimals) | Round n to decimals decimal places |
abs(n) | Absolute value of n |
Conditional function
if(condition, then, else)Returns then if condition is truthy, otherwise returns else. Conditions support ==, !=, >, <, >=, <=.
Example:
if({{plan}} == "enterprise", {{seats}} * 99, {{seats}} * 49)String functions
| Function | Description |
|---|---|
concat(a, b, ...) | Concatenate all arguments into a single string |
upper(s) | Convert string to upper case |
lower(s) | Convert string to lower case |
Regex function
regex(value, pattern)Returns true if value matches the regular expression pattern, false otherwise. Useful inside if() conditions.
Display
Calculated fields are shown to the respondent as a read-only input — they can see the computed result but cannot edit it. The field updates in real time as the respondent fills in the source fields.
Server-side recomputation
For security, calculated field values are recomputed on the server when the form is submitted. The client-displayed value is for UX only — the server always calculates the final value independently. This means calculated field values cannot be tampered with by a respondent or a browser extension.
