Prorated Salary Calculator

What is a Prorated Salary?

A prorated salary is a proportional amount of compensation paid to an employee who works only a portion of a standard pay period. Proration commonly occurs when an employee joins a company mid-month, leaves before the pay cycle ends, transitions between full-time and part-time status, or takes unpaid leave.

How to Calculate Prorated Salary

To determine a prorated paycheck, calculate the daily or hourly wage rate based on the regular full pay period salary, then multiply that rate by the number of actual days or hours worked during that period.

The mathematical formula for calculating prorated salary is:

$$\text{Prorated Salary} = \left(\frac{\text{Base Period Salary}}{\text{Total Working Units in Period}}\right) \times \text{Actual Units Worked}$$

For example, if an employee earns $5,000 monthly in a month with 22 working days, their daily rate is $227.27. If they start work on the 10th working day and complete 13 days, their prorated earnings equal $2,954.55 ($227.27 x 13).

Common Scenarios Requiring Salary Proration

• New Hires Starting Mid-Month: Employees who start on a day other than the first day of the pay period receive pay for the days worked.
• Terminations & Resignations: Departing employees receive prorated earnings up to their official last working day.
• Unpaid Leave: Deductions for unpaid personal days or non-FMLA medical leave require prorating the monthly base salary.
• Schedule Changes: Switching from 40 hours per week to part-time hours mid-pay cycle.
