How to price a job so it actually pays
- Labor at your real rate. Your rate has to cover drive time, quoting, insurance and slow weeks, not just the hours on site. The hourly rate calculator works it out.
- Mark up materials. 15% to 30% is common. It pays for the supply-house run, returns, and the risk of eating a defective part.
- Charge flat fees separately. Trip charges and disposal are fees, not materials, so they don't get a markup.
- Check your state's tax rules. Many states tax materials but not labor; some tax both. This calculator taxes materials only.
- Take a deposit on bigger jobs. 25% to 50% up front covers materials before you buy them. Some states limit deposits on home improvement work, so check yours.
