Why this tool exists

Most contractors know what they pay an employee per hour. Far fewer know what that employee actually costs per billable hour after taxes, insurance, benefits, vehicle, tools, and overhead. The gap between "wage" and "true cost" is where margins quietly disappear — especially for shops with 1-10 techs who don't have a CFO running these numbers.

Research from ServiceTitan, BuildVision AI, and trade forums consistently shows that most small trades contractors don't calculate a true break-even billable rate. They price from gut or from competitor rates, then wonder why a busy year still ends with thin profits.

This tool does the math in 30 seconds. No spreadsheet, no signup, no sales call.
