How big should your HR team be? To determine that, you need to calculate the HR-to-employee ratio. Read on to learn what this ratio means, why it is important, and what factors to consider when calculating the ratio.
The HR-to-employee ratio is an expression of the number of HR employees needed to support 100 full-time employees. It is used to provide a roadmap on when to scale the HR team along with the company workforce. A good rule of thumb to start is 2.5 HR employees per 100 full-time employees. The following sections will discuss factors and circumstances that help you determine if you need a bigger ratio.
The HR-to-employee ratio is important because it provides data in making organizational decisions regarding HR support.
Consider the following factors to determine the ideal HR-to-employee ratio. Although not a complete list, this will help you determine the ratio best for your organization.
If your evaluation points towards having a larger HR team but there is no money to hire more people, obviously your options are limited. However, your study does provide data to share with leadership to document current needs and plan for the future.
Organizations that rely heavily on technology need smaller HR teams and a smaller HR-to-employee ratio because more automated tasks reduce the number of people required.
Different industries have unique challenges that influence the HR-to-employee ratio. Here are a few examples of conditions that impact the appropriate size of an HR team:
A 2021 study by Indeed concluded that an average HR staff to employee ratio is around 2.57 for all organizations. Small organizations have higher ratios with an average of 3.40. Medium organizations often have ratios around 1.22 while a normal ratio for large organizations is 1.03.
