Prorated Salary Calculator
Starting or leaving a job mid-pay period? Calculate exactly how much you should receive for a partial pay period. Enter your annual salary, the total and actual work days, and your pay frequency to get the prorated amount.
Prorated salary is the adjusted pay you receive when you work only part of a pay period. This commonly happens when you start a new job, leave a job, take unpaid leave, or transition between full-time and part-time.
The standard proration formula is: Prorated Pay = (Annual Salary / Pay Periods) x (Days Worked / Total Work Days in Period). On a $75,000 annual salary paid monthly, a full month's gross pay is $6,250. If the month has 22 work days and you worked 14, your prorated pay is $6,250 x (14/22) = $3,977.27.
There are a few different methods companies use to prorate:
- Work days method: Divide by actual business days in the period (most common and what this calculator uses)
- Calendar days method: Divide by total calendar days in the month (less common but simpler)
- Annual work days method: Use 260 work days per year as the denominator regardless of the month
Check with your HR department to confirm which method your company uses, since the result can vary by a few dollars depending on the approach. The work-days method is the most widely used and is generally considered the most fair.
