BLS Occupational Employment and Wage Statistics SOC 33-9032 (Security Guards

Security Guard Contract Pricing Calculator

Derive a commercial security service contract's bill rate per guard-hour, gross margin per hour, and monthly 24/7-coverage economics from first-principles cost inputs (guard wage, employer payroll burden including FICA / FUTA / SUTA and NCCI class code 7720 workers' compensation, uniform and equipment allocation, supervisor leverage cost, target gross margin, and contract type). Cross-checks the implied markup multiplier against the ASIS International 1.50-1.85× contract-guard benchmark and the implied gross margin against the ASIS 8-15% gross-margin band. Tool, not advice — for a binding bid, commission a cost-of-doing-business analysis from an ASIS-credentialed (CPP, PCI, PSP) cost analyst.

SDM Magazine annual industry survey (RMR multiple

Alarm Monitoring MRR & Portfolio Valuation Calculator

Compute a monitored-alarm portfolio's account-level economics — monthly gross profit per account, implied gross margin on RMR, average account life from annual churn, lifetime value per account, LTV-to-CAC ratio, and new-account payback months — and surface the industry-standard 35×, 50×, and 60× RMR portfolio valuation triplet (SDM Magazine annual survey, Barnes Associates, Davis M&A Group benchmarks). Tool, not advice — for a binding portfolio valuation or sale, engage Barnes Associates, Davis M&A Group, or another alarm-industry specialty advisor.

HOA Gate Access System ROI Calculator

Compute the buy-versus-status-quo economics for replacing some or all staffed gate-guard coverage with an unattended gate-access system (keypad / RFID / LPR / managed-cloud access). Inputs: existing guard hourly cost, hours replaced per day, proposed system capital cost, monthly hosted-software cost, useful life. Outputs: monthly net savings, payback months, 5-year cash savings, 5-year NPV at an 8% hurdle rate, simple ROI, and a buy / unfavorable / marginal recommendation. Tool, not advice — the board should obtain three vendor quotes against a consistent scope of work and route the decision through the association's capital approval process consistent with the governing documents and applicable state HOA statute.
