Prorated Salary Calculator

About this calculator

This calculator finds prorated pay for a partial work period, using a daily rate (annual salary ÷ working days per year × days actually worked) or a similar calculation based on a pay period. It's the standard way employers calculate pay for an employee who starts, leaves, or takes unpaid leave partway through a pay cycle.

HR and payroll staff use it when onboarding a new hire mid-month, processing a final paycheck for someone who resigns, or docking pay for unpaid leave, so the employee is paid fairly for exactly the days worked. Enter the annual or period salary, the total working days in the period, and the days actually worked.
