# Create and edit formulas in Smartsheet

Use formulas to calculate numeric values or automate aspects of your sheet. You can create formulas, for example, to sum a range of expenses, or to check a box when a specific value is entered in a field.

Users on an Enterprise plan can use AI to generate formulas. Learn more.

The sheet Owner and Admins can create and edit formulas in locked and unlocked fields. The Owner, Admins, and Editors can create and edit formulas in unlocked fields.

### Create a formula

You can create a formula in the following cell types:

- Cells not used for dependencies or resource management. Learn how to enable dependencies and use predecessors.
- Text/Number (as long as they're not used in dependencies or resource management)
- Contact List cells (as long as they're not used in resource management)
- Date (as long as they're not used in dependencies or resource management)
- Dropdown List
- Checkbox
- Symbol
- % Allocation

To place a formula in a cell:

- Select the desired cell.
- Type an equal sign in the cell, and then type the calculation.
- After you’ve typed in your formula, press
**Enter**.

You can now see the result in the cell containing the formula.

You can place formulas in Contact List cells. Automatically assign people to tasks with a VLOOKUP formula, for example. You can’t place formulas in Contact List cells used for resource management.

#### Functions

Formulas can include functions, such as SUM, AVG, or IF. Smartsheet Functions performs calculations or manipulate data in sheets.

#### Formula operators

You can use the following operators in Smartsheet formulas.

Symbol | Description |
---|---|

+ | Add |

- | Subtract |

* | Multiply |

/ | Divide |

^^ | Exponent |

< | Less than |

> | Greater than |

>= | Greater than or equal to |

<= | Less than or equal to |

= | Equal to |

<> | Not equal to |

### Edit an existing formula

To edit an existing formula:

**Double-click**a cell containing the formula to open it for editing.- Make your desired formula changes, and then press
**Enter**.

If you change your mind about editing the formula, press the**Esc**key to exit edit mode and revert to the pre-edited formula.

### Tips for easier formula creation

#### Use column formulas

When you need a formula applied consistently and uniformly to an entire column, column formulas are the perfect solution. Build your formula in a cell, and quickly convert it to apply to every cell in the column. Regardless of how new rows get inserted into the sheet, the column formula will automatically apply. Learn how to set formulas for all rows with column formulas.

#### Use the sum tool

If you're not sure which function to use, you can select the **down** arrow on the right of the **Sum** button in the toolbar and select a function.

The **Sum** button will attempt to provide you with a formula based on the cell you have selected in the sheet and any hierarchical relationships with the selected cell. For example, selecting the cell of a parent row, then clicking the **Sum** icon will produce a =SUM(CHILDREN()) formula in the cell.

After you create a formula, you can modify it at any time by double-clicking in the selected cell or by pressing **F2** (**fn + F2** on a Mac).

#### Work with percentages

Smartsheet treats percentages as values between 0 and 1. When you create formulas in columns formatted for percent (using the ** Percentage Format** button in the toolbar), use **decimal values**. For example...

=0.5 + 0.4

...will return **90%** in a column formatted for percentage...

=5 + 4

...will return **900%** in a column formatted for percentage.

#### Copy a formula with drag-fill or auto-fill

If you have a formula that you’d like to use in multiple cells without having to manually type the formula in each cell, use the following methods to quickly copy the formula to other areas of your sheet:

- Drag-fill—You can drag from the lower-right corner of a selected cell to copy a formula across contiguous cells in the sheet. As you copy, the formula will automatically change its respective cell references.
- Auto-fill—You can have Smartsheet automatically copy a formula to new, vertically adjacent cells that enter the sheet. When auto-filled, the new formula will automatically change its respective cell references.

Learn how to drag-fill and auto-filling formulas and formatting.

### Areas where formula use is restricted

These cells can't contain formulas:

- Contact list cells that are being used in resource management
- System cells (for example, Modified By)
- Default columns (attachments, comments, row action indicator)
- The following cells being used for
**dependencies**and**resource management**:- Start Date
- End Date
- Duration
- Predecessors
- % Complete

You can't create formulas in these features:

- Forms
- Update requests (You can still view formula results in update requests, but they can't contain standalone formulas.)
- Reports (You can still view formula results in reports, but they can't contain standalone formulas.)
- Dashboards (You can still view formula results in dashboards, but dashboards can't contain standalone formulas.)

You can't edit formulas from the following features in Smartsheet:

- Forms
- Update requests (You can still view formula results in update requests, but the formulas can't be edited.)
- Reports (You can still view formula results in reports, but the formulas can't be edited.)
- Dashboards (You can still view formula results in dashboards, but the formulas can't be edited.)
