According to BSCAI and ISSA industry data, the average janitorial business earns a 10–28% net profit margin. Solo operators typically hit 25–30%, while mid-size companies (10–50 employees) average 8–15% after accounting for supervisors, vehicles, and admin overhead.
A complete profit calculation includes: base labor cost, payroll taxes (FICA at 7.65%, FUTA at 0.6%, SUTA at 1.2–4.1%), workers' compensation insurance (~3.7% for janitorial), cleaning supplies (2–5% of revenue), and general overhead (8–15% for insurance, equipment, vehicles, and admin). The national median janitor wage is $16.29/hour (BLS, May 2024).
Divide your monthly profit by the total square footage × number of cleanings per month. For example, if you profit $1,300/month on a 10,000 sqft building cleaned 5× per week (21.7 visits/month), your profit per cleaning per square foot is $0.006, or $0.06/sqft/month.
The combined employer payroll burden for janitorial workers is approximately 14.8%: FICA 7.65% (SSA), FUTA 0.6% (IRS), SUTA 2.7% national average (DOL), and workers' compensation 3.7% (NCCI class code 9014). This means a $16.29/hour janitor actually costs about $18.70/hour before any benefits.
