SettingsSettings for this calculationUS
The total quoted or estimated cost of the project.
Use the full project quote, including materials and labor, for a meaningful comparison between quotes.
The total square footage the cost covers.
Use the same area definition (e.g. finished floor area) across every quote you're comparing — mismatched area definitions make comparisons meaningless.

What this calculation does not cover
- Rate per square foot is not constant with job size, because a large part of any job does not scale with area. Mobilization, setup and teardown, a dumpster, permits and single fixed items like one kitchen or one bathroom cost much the same over 300 sq ft as over 1,500. A small job's rate therefore reads high and a large one's reads low even when both are priced fairly, and comparing across sizes on rate alone penalizes the small job.
- Floor area is not the surface being worked. Painting, drywall, insulation and ductwork follow wall and ceiling area, so a room with 12 ft ceilings or a space open to a second floor costs well above the rate the same footprint produces at 8 ft. Two quotes over identical square footage can be honestly far apart on this figure for that reason alone.
