Real project costs, before you call a contractor.
Every calculator here shows its work — materials, labor, permits and contingency as separate lines — so you can hold a contractor quote up against it and see exactly where the difference is.
Why the breakdown matters
A single number tells you nothing about why one bid is thousands under another. Usually the gap is scope: one contractor included the permit, the patch and the haul-away and the other quoted labor only. Comparing line by line is the only way to see that.
