Formulas can contain mathematical equations, references to other line items or modules, logic statements, and Anaplan functions. You enter a formula once, and it's applied across all dimensions used in the module.

There are several ways you can add a formula:

- Use the formula editor. This option is best for most calculations, because the editor has syntax highlighting and autocomplete. You can also switch between modules while writing formulas.
- Use the formula bar. The formula bar is above the line items, under
**Line Item Formula**. This option is best for short and simple formulas. - Type directly into the
**Formula**cell.

To find information on functions, operators, and how to write formulas, see All functions.

You can set up formulas in these ways:

- Formulas for specific line items. You can choose which model versions to apply the formula to in the
**Formula Scope**column in**Blueprint**. - Version formulas for line item subsets. This kind of formula applies to a specific version in a module. Each line item in the subset must have versions applied to it. The formula applies to one module only, even if the subset includes line items from different modules.
- Version formulas for the model. The formula is set on a specific version dimension. This kind of formula is typically used for variance calculations that apply to the whole model.
