# Available calculations > The full, searchable list of calculations you can build in the GUI, plus custom formulas for anything beyond them. ## GUI calculations Below are the supported [calculation builders](/docs/calculation-builder) for creating metrics. When none fit, use a [Custom formula](#formulas) with AQL. ## Formulas When the available calculations aren't enough, use **Custom formula** to write your own expression in [AQL](/as-code/aql). This is the same as switching to Formula mode, and it gives you full control over the field's logic. See full list: [AQL functions](/reference/aql/functions).
