Fair range. Cost to deliver is the break-even, the red line on the gauge, not the price to demand. A fair bid sits in the green band above it, roughly 8 to 45 percent over depending on trade and market, with most landing between 18 and 28. Most contractors earn a margin in that band, and they should: nobody works for free, and if the job were easy you would not need one.

Calculator FAQ

Using the bathroom remodeling calculator.

How does the bathroom remodeling cost calculator work?+
It prices the job from the ground up: Craftsman labor hours times the BLS wage for your metro, plus PPI-adjusted materials, the verified permit fee where we have it, and a per-trade overhead benchmark. That gives a cost to deliver, and the fair range sits above it. Pick your city and service and it sizes the number to your market.
Is it free, and do I have to enter my contact information?+
Free, and no. There are no lead forms and no signup. The calculator runs in your browser on published cost data, so you get the number without handing over your email or phone.
How accurate are the estimates?+
They are modeled from federal wage data, a licensed cost book, current material price indices, and real city permit fees, not survey self-reports or scraped quotes. Treat the result as a fair market benchmark to check a bid against, not a binding quote. Your home's specifics and a contractor's scope still move the final number.
Can I check a contractor's bid with it?+
Yes. Paste the quote into the bid checker and it grades the number against the local range, the lowest realistic price, and the typical contractor margin. A margin between 18 and 28 percent is normal and earned, with a fair ceiling of 24 to 45 depending on the trade, so the checker flags a bid that runs well past that and gives you something concrete to negotiate with before you sign.
