How Much Paint Will This Job Need?
Estimate gallons for the painted surface, number of coats, coverage, and extra paint. The 400-square-foot default follows Dunn-Edwards’ general one-coat planning guidance; rough or porous surfaces may cover less.
Planning estimate only. Product, color change, application method, texture, porosity, overspray, and surface condition can change real coverage. Dunn-Edwards recommends considering two finish coats for the truest color and coverage. Check Dunn-Edwards’ paint planner.
House painting profit formula
Job revenue = painted square feet × price per square foot.
Job profit = job revenue − paint/materials − labor − travel and prep costs.
Monthly profit = job profit × jobs per month − monthly overhead.
FAQ
Should prep time be included? Yes. Washing, sanding, caulking, masking, setup, cleanup, and callbacks all affect profit.
Does this work for exterior painting? Yes, but exterior jobs may need extra inputs for ladders, lifts, weather delays, and surface repair.
Are results exact? No. This is a rough planning calculator.
