Employer Costs for Employee Compensation Technical Note


Employer Costs for Employee Compensation (ECEC), a product of the National Compensation Survey,
provides the average employer cost for wages and salaries as well as benefits per employee hour

state and local government. Excluded from private industry are the self-employed, agricultural
workers, and private household workers. Federal government workers are excluded from the public

Total benefit costs consist of five major categories and include 18 benefit costs:
* Paid leave - vacation, holiday, sick, and personal leave; 
* Supplemental pay - overtime and premium, shift differentials, and nonproduction bonuses; 
* Insurance - life, health, short-term and long-term disability; 
* Retirement and savings - defined benefit and defined contribution; and 
* Legally required benefits - Social Security (refers to Old-Age, Survivors, and Disability
  Insurance (OASDI) program), Medicare, federal and state unemployment insurance, and Workers’ 

All workers are included in the benefit cost estimates including those that do not have plan access
or do not participate. Costs are also affected by other factors such as cost sharing between
employers and employees, plan features, and plan generosity. For the latest information on the
percentage of workers with access to and participating in employer-sponsored benefit plans,
including health care and retirement and savings plans, see

The “National Compensation Measures” provides additional details on the sample design, calculation
methodology, and resources explaining changes over time. (See

government establishments that provided data at the initial interview.

Measures of reliability
Relative standard errors (RSEs) provide users a tool to ascertain the quality of an estimate to
ensure that it is within an acceptable range for their intended purpose. RSEs are available at and database query tool at

Compensation cost levels in state and local government should not be directly compared with 
levels in private industry. Differences between these sectors stem from factors such as variation
in work activities and occupational structures.

Area definitions

No. 13-01, dated February 28, 2013. For more information see
