+### Generating Cost Estimate Report for Tasks
+
+To automatically estimate the cost of translation or proofreading for a task, select the **Create Cost Estimate Report** option during task creation.
+
+Once selected, a required [**Rates Template**](/project-reports/#rate-templates) drop-down will appear. Choose a saved template to calculate the cost estimate based on the selected strings or files.
+
+After the task is created, a Cost Estimate report will be generated automatically and become available in the [Archive](/project-reports/#archive) section. The estimated cost will also be displayed on the task card in the Board section. You can open the task to view the **Estimated Cost** section, which includes the following details:
+
+* The calculated cost based on the selected rates template
+* A clickable report title (e.g., Report #123) that links to the full report in the Archive section
+* The report generation date
+
+If the task scope changes (e.g., files or strings are modified), a new Cost Estimate report will be generated automatically to reflect the updated estimate.
+
 ### Task Templates
 
 Use task templates to save the configuration of the **Languages** section, including target languages and member assignments. Templates help you quickly apply these configurations when creating new tasks, saving time and ensuring consistency.
