In account-based models, *Dimension Member Formulas* are configured in the *Account* dimension type to perform calculations using existing dimension members, such as *Labor as a Percent of Cost* (calculated using the *Labor* and *Cost* dimension members.

The previous figure an example of a dimension member formula for calculating labor as a percentage of total cost. You can see:

- The formula in the
*Account*dimension. - The results in a table in a story.

You can use dimension member formulas to calculate account values that are restricted to other dimension member values such as *Prior Year Revenue*. A dimension formula is available in any story that uses a model that contains the account dimension with a formula.

An account dimension formula can be used as it was created in the dimension, or it can be modified in specific models. In this scenario, the model can contain its own version of the dimension formula.
