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: most jobs land at a 15 to 22 percent margin on the bid, roughly 18 to 28 percent over the cost to deliver, leaner or richer by trade and market. Contractors earn that, 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. You get the number with no signup: the calculator runs in your browser on published cost data, so nobody asks for your email or phone to see the answer.
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 15 to 22 percent margin on the bid is normal and earned, roughly 18 to 28 percent over the cost to deliver, with a fair ceiling higher on complex trades, so the checker flags a bid that runs well past that and gives you something concrete to negotiate with before you sign.
