What Are Staffing Ratios?

Staffing ratios are metrics that represent the relationships between various staffing levels, costs, and productivity indicators. By analyzing staffing ratios, companies can answer important questions like:

• Are we overstaffed or understaffed?
• Is our revenue generation per employee optimal?
• How do we compare with competitors in our industry?

These ratios can be particularly valuable for assessing both the efficiency of individual departments and the organization as a whole. For instance, ratios like revenue per employee can provide insights into productivity, while the ratio of HR staff to total employees sheds light on resource allocation in the HR function.

10 Staff Ratios for Every Business

1. Revenue per Employee

Revenue per employee is a primary measure of a company’s productivity. It divides total revenue by the number of employees, showing how much revenue each employee generates. It is calculated as follows:

Revenue per Employee = Annual Revenue / Total Employees

A higher ratio indicates higher productivity and efficiency, suggesting that employees are contributing significantly to the company’s revenue. In comparison, a lower ratio can indicate that there is an opportunity to improve productivity.

2. Revenue per Function Employee

Revenue per function employee focuses on productivity within specific departments, such as finance, marketing, or sales. This ratio provides a closer look at departmental efficiency, helping companies to optimize staffing levels. The formula is:

Revenue per Function Employee = Annual Revenue / Employees in the Function

This ratio is particularly useful for commercial functions, such as Sales, Marketing, and Customer Support, where revenue is a key driver for the number of headcount required.

3. Function Employees as % of Total Employees

This ratio measures the proportion of employees in a specific function relative to the entire workforce, helping companies understand their staffing distribution.

Function Employees as % of Total Employees = (Employees in the Function / Total Employees) * 100

Tracking this ratio can reveal whether particular departments are overstaffed or understaffed when compared to industry standards.

4. Operating Expense per Employee

Operating expense per employee measures the average cost to maintain each employee, including salaries, benefits, and other overheads. Lower ratios can indicate a more cost-efficient workforce. The formula is:

Operating Expense per Employee = Annual Operating Expenses / Total Employees

This ratio helps organizations balance expenses and ensure that staffing costs align with revenue and profitability goals.

5. HR Staff to Employee Ratio

The HR staff to employee ratio measures the number of HR staff supporting the workforce. It helps determine whether HR staffing is proportional to the needs of the workforce, especially as a company scales. Here’s how to calculate it:

HR Staff to Employee Ratio = Total HR Staff / Total Employees

A lower ratio might indicate under-resourced HR, while a higher ratio could suggest inefficiencies in HR processes.

6. Management to Staff Ratio

The management to staff ratio compares the number of managers to non-managerial employees. This is a classic metric and sometimes referred to as the average span of control. It is used for assessing organizational hierarchy and can indicate if a company is too top-heavy or too lean in management. The formula is as follows:

Management to Staff Ratio = Total Managers / Total Staff (non-managers)

A high ratio could mean excessive management overhead, while a low ratio may indicate a need for more managerial oversight.

7. Turnover Rate

Employee turnover rate measures the rate at which employees leave the organization, providing insights into employee satisfaction and retention. High turnover can disrupt productivity and incur additional hiring costs. It is calculated as:

Turnover Rate = (Employees who left during a period / Average number of employees) * 100

Tracking the turnover rate enables companies to identify trends, address retention issues, and maintain a stable workforce.

8. Absenteeism Rate

The absenteeism rate tracks the percentage of workdays missed due to unplanned absences. High absenteeism can be a sign of workplace issues such as burnout or low morale. This is the formula:

Absenteeism Rate = (Total Days Absent / Total Workdays) * 100

9. Time to Hire (TTH)

Time to hire measures the average time required to fill an open position, reflecting recruitment efficiency and attractiveness as an employer. Shorter times indicate effective hiring processes, while longer times may point to issues in recruitment or a competitive job market. It is calculated as:

Time to Hire = Total Days to Hire / Total Number of Positions Filled

Optimizing time to fill can help companies reduce downtime and maintain consistent productivity levels.

10. Labor Cost as % of Revenue

Labor cost as a percentage of revenue shows what portion of the company’s revenue goes toward paying employees. This ratio is key for managing budgets and profitability, particularly in labor-intensive industries. The formula is as follows:

Labor Cost as % of Revenue = (Total Labor Costs / Total Revenue) * 100

A high percentage may signal a need to optimize workforce expenses, while a lower percentage can indicate an efficient use of labor. This formula can also be split by function for a deeper understanding of where opportunities may exist.
