Prorations Explained

Prorations are essential in payroll calculations, primarily when employees work fewer days than usual in a given pay period. Our system prorates using the National Payroll Institute (NPI) recommended method. Here’s how it works.

Understanding the 260-Day Formula

The 260-day formula assumes an employee works 5 days a week for 52 weeks a year, totalling 260 workdays. When employees don’t work all scheduled days in a pay period, prorations adjust their pay to reflect the actual days worked.

Formula:

Prorated pay = (Days Worked / 10) X Gross Pay for the Period

In this case, 10 days represent the standard workdays in a bi-weekly pay period.

Example Calculation

Imagine an employee is on a bi-weekly pay schedule with a gross salary of $1000 for the pay period. However, the employee only worked 5 out of the 10 days in that period. Here’s how you would calculate their prorated pay:

  1. Determine the ratio of days worked to total workdays in the period. 5/10 = 0.5

  2. Multiply this ratio by the gross salary for the period. 0.5 X $1000 = $500

Result: The employee’s prorated pay for that pay period would be $500.

Why the 260-Day Formula?

The 260-day formula ensures consistent and fair prorations by accounting for the number of workdays in a pay period. It accurately reflects an employee’s earnings based on the days they worked.
