You can easily set up Hourly Wage of an employee to automatically calculate their overall wage when you download the Timesheet or the Payroll Report. 

All you need to do is go to your dashboard's personnel section, select an employee and look for the "Hourly Wage" field. Just set the hourly wage here and leave the AttendanceBot to calculate the wage for your employees. 

The overall wage can be seen on the timesheet and payroll reports at the bottom.
