#### Effects of deleting a calculated field

Deleted calculated fields remain visible in the Fields table. If your calculated field had a fixed or sliding [tracking window](https://help.impact.com/brand/what-would-you-like-to-learn-about/advocate-program/manage-advocate-participants/custom-and-calculated-fields/tracking-windows-for-calculated-fields-explained), then previous calculations may also be visible on individual participant profiles.
