Deduction of money above the allowed number of leaves to the employee is called No Pay Leave Deduction. You can calculate the No Pay Leave Deduction amount by using 2 methods: Working Days or Calendar Days depending on the company policy. If the employer chooses to deduct on a working day basis then divide the Gross Salary by 22 days and then multiply it with the number of No Pay Leaves. Whereas, if the employer decides to make the No Pay Leave Deductions then divide the gross salary by calendar days of that respective month and multiply with the number of No Pay Leaves.
