Many independent tradespeople and contractors undercharge because they only calculate raw materials and basic hourly time. A profitable quote requires factoring three core elements:
- Direct Labor: Include travel time, job prep, cleanup, and actual tool time.
- Materials Markup: Covering sourcing, hauling, and warranty risk on parts (typically 15% to 30%).
- Overhead & Contingencies: Tool wear, vehicle maintenance, insurance, and administrative hours.
