True Costs of Rounding Rules

Have you ever wondered what certain rounding rules would cost you? Let’s take a look at the following example.


What are the takeaways? 

  • Rounding will cost more if minutes are rounded backwards for arrival times and forwards for departure times.
  • To determine right rounding rule, identify whether employees are more likely to work more or less than their actual schedules. Do this by capturing both times and monitoring the discrepancies over a period of time for several groups.
  • Be sure to sample from a large pool of employees, but be aware of patterns that may arise in certain worker groups, departments, or locations.
  • Understand your purpose for rounding rules. If you are giving a rounding rule because employees are commonly 15 minutes late, why not consider pushing the start of the shift back 15 minutes? External issues, such as traffic, could be impeding attendance.
  • Whatever rounding rule you choose, be sure that it is fair and consistently used. It should not clearly benefit employer or employee exclusively.

Here’s another quick overview for our example.
