Average Security Guard Salary in Missouri

Security guards and officers protect property, assets, and people at a wide range of locations — retail stores, hospitals, corporate offices, industrial facilities, government buildings, airports, and residential communities. Duties range from access control and patrol to emergency response, surveillance monitoring, and loss prevention. The BLS reports a national median annual wage of $34,750 for security guards, though compensation varies significantly by sector: unarmed retail guards earn near the lower range, while armed security officers, federal protective security officers, and private security specialists at high-risk facilities can earn $50,000–$75,000+. The profession offers significant entry-level accessibility, with most positions requiring only a high school diploma and state licensure.

In Missouri, security guards earn an average of $34,785 per year as of 2026, with salaries ranging from $22,764 for entry-level roles to $50,675 for the most experienced professionals — +6.3% below the national average. Pay is influenced most by armed vs. unarmed status — armed security officers typically earn $6,000–$15,000 more annually than unarmed guards at comparable facilities; firearms certification and licensing are required, client sector — federal contract security officers (protecting government buildings under federal protective service contracts), hospital security, and data center security pay above retail and residential guard positions, and the specific metro area within Missouri.
