On the Salary Calculator page there is a blue "My Saved Reports" button above the salary graph. Click the button. This will open a menu with your most recent reports shown. Find the report you wish to rename here—or click the "View & Manage All Reports" link in the bottom left of this menu to find it. Once you've found the report you wish to rename, simply click the "Rename" button next to the report's current name. Type in the new name and click "Submit." Your report is now saved with the new name.
