Calculating salary for an uncompleted monthly period typically involves prorating the salary or wages based on the number of days worked during that period. Here's a general formula to help you calculate the pay for an uncompleted monthly period:

Daily Rate=Number of Workdays in the MonthMonthly Salary​

$\text{Pay for Uncompleted Period}=\text{Daily Rate}\times \text{Number of Days Worked}$

To automatically calculate salary proration for employees during payroll processing, it is crucial to accurately input the following information.

Employee Management > Employee > Employment > Date Joined:

A scenario involving an employee who starts work after the 1st day of the month.

Employee Management > Employee > Employment > Date Left:

A scenario involving an employee who resigns before the last day of the month.
