Federal law provides special salary rates to Federal employees who serve in law enforcement. Additionally, Federal special agents and inspectors receive law enforcement availability pay (LEAP)—equal to 25 percent of the agent's grade and step—awarded because of the large amount of overtime that these agents are expected to work. For example, in 2003 FBI agents enter Federal service as GS-10 employees on the pay scale at a base salary of $39,115, yet earned about $48,890 a year with availability pay. They can advance to the GS-13 grade level in field nonsupervisory assignments at a base salary of $61,251, which is worth $76,560 with availability pay. FBI supervisory, management, and executive positions in grades GS-14 and GS-15 pay a base salary of about $72,381 or $85,140 a year, respectively, and equaled $90,480 or $106,430 per year including availability pay. Salaries were slightly higher in selected areas where the prevailing local pay level was higher. Because Federal agents may be eligible for a special law enforcement benefits package, applicants should ask their recruiter for more information.

Total earnings for local, State, and special police and detectives frequently exceed the stated salary because of payments for overtime, which can be significant. In addition to the common benefits—paid vacation, sick leave, and medical and life insurance—most police and sheriffs' departments provide officers with special allowances for uniforms. Because police officers usually are covered by liberal pension plans, many retire at half-pay after 20 or 25 years of service.
