Whole-House & Project Cost
The whole-project & quote-check cluster: cost to paint a house, whole-house interior + exterior, average cost by home size (a labeled floor-area-to-paintable factor), a painter quote checker (derived $/sq ft vs a labeled band), a painting labor cost estimator, and cost to repaint a house. Planning estimates from your own numbers — not a bid.
Planning estimate: this is a planning estimate from the numbers you enter — not a bid or a contract. Paint quantity and price depend on wall texture, porosity, color change, number of coats, prep and patching, trim and ceilings, height and access, and local labor. Get itemized written quotes from licensed, insured painters before you commit.
Cost to Paint a HouseEstimate the cost to paint a house from the prices you enter: paintable area times your dollars per square foot, plus labor, add-ons and contingency.Whole-House Interior + Exterior CostAdd your interior and exterior painting estimates into one whole-house total. Reuse the results from the interior and exterior cost calculators.Average Cost by Home SizeTurn your home's square footage into a paintable area with a labeled factor, then estimate the paint cost. A planning proxy — measuring beats it.Painter Quote CheckerCheck a painter's quote by dividing it by your paintable area, then compare the derived dollars per square foot to a labeled sanity band for that job type.Painting Labor Cost EstimatorSplit labor out of a paint job: your paintable area times your labor dollars per square foot, scaled by height and access multipliers you set.Cost to Repaint a HouseEstimate the cost to repaint a house — often fewer coats and lighter prep than a first paint — from your own prices, labor and a contingency buffer.
Every Whole-House & Project Cost tool is calculated server-side — visible immediately — with its formula, a worked example and a reference table, and works on the surfaces you measure and the prices you enter from your own quotes. Background reading is in the guides.
