# About Formulas

Formulas perform calculations on either constant values or members of the account dimension. References to members are enclosed in square brackets (see following illustration). Some formulas are designed for use in models and others are designed for use in tables in stories.

In the Modeler, when you create a new account dimension, the Formula column is automatically added. You can enter a formula directly in the formula column, or select a formula cell and click to open the Advanced Formula Editor. In the Modeler, formulas apply to individual account members (rows).

This example shows a formula using basic arithmetic syntax to perform a calculation referring to other members of the account dimension:

In stories, you can create calculations in tables using the Calculation Editor, or you can type formulas in grid cells outside of a table using the formula bar. For more information, see Calculation Editor and The Formula Bar.
