Most contractors don't lose money on bad jobs. They lose it on jobs that looked fine.

The math that actually matters: burdened labor rate (wage × 1.25–1.4, not the number on the paycheck), your overhead recovery rate, and dividing — not multiplying — to get your real price.

JobProfit is a $49 toolkit: a real working spreadsheet calculator plus 10 real contractor quotes broken down line by line, so you can check any job in 15 minutes before you send the quote.
