Use case

Pivot table calculated field formula generator for spreadsheet work.

Build formulas for PivotTable calculated fields where the formula should reference source field names such as Revenue, Cost, Quantity, or Units rather than worksheet cells.

What this page gives you

  • A draft calculated-field formula using the field names you provide.
  • A plain-English read of whether the metric is a difference, ratio, margin, or average.
  • Checks for field-name references, aggregation limits, and helper-column cases.

When to use it

Use this page when the metric should live inside a PivotTable or Google Sheets pivot table as a calculated field, such as profit, gross margin, average order value, or cost variance. Pivot formulas are different from normal worksheet formulas because they usually reference source field names rather than individual cells.

Do not force every row-level rule into a pivot calculated field. If the calculation must happen before the pivot aggregates the data, add a helper column to the source table first and then summarize that field in the pivot.

Worked example

For a pivot source with Revenue and Cost fields, a calculated field can show gross margin as a percentage.

=('Revenue'-'Cost')/'Revenue'

The formula subtracts Cost from Revenue, divides by Revenue, and can be formatted as a percentage in the pivot table values area.

Check before you paste

  • Use pivot field names, not A1-style cell references.
  • Confirm the referenced fields are available in the pivot source data.
  • Use a helper column in the source table when the calculation needs row-level logic before aggregation.
