Employee True Cost Calculator for Construction

Labor is the heartbeat of any construction operation — and it is also the most expensive and complex cost to calculate accurately. Workers' compensation insurance alone sets construction apart from most industries: rates run 5–15% of payroll depending on trade classification, with roofers and ironworkers at the high end and finish carpenters and project managers at the lower end. A laborer earning $25/hour on paper actually costs $33–$40/hour when you factor in workers' comp (8–12% for general construction), employer FICA (7.65%), federal and state unemployment taxes, general liability insurance allocation, OSHA-mandated safety training, tools and equipment, and vehicle or travel allowances. Seasonal hiring adds another wrinkle — bringing on crew members for the building season means front-loading training costs that you recoup only if they stay the entire season. Year-round key employees (foremen, lead carpenters, equipment operators) command premium pay and benefits because losing them over the winter to another contractor is devastating to spring startup. This calculator is pre-loaded with construction-specific cost factors including elevated workers' comp rates, OSHA compliance costs, and seasonal employment patterns. Use it to understand the full burden of each crew member so you can bid jobs accurately and make informed decisions about when to hire versus when to subcontract specialized work.
