House Painting Cost Calculator

Estimate the cost of painting your home with our interior and exterior house painting cost calculator. A fresh coat of paint is one of the most cost-effective ways to transform the look of your home, protect surfaces from weather and wear, and increase property value. Our calculator helps you estimate costs based on the scope of your project, the surface area to be painted, paint quality, and whether you plan to hire professional painters or take on the work yourself.

Interior painting costs depend primarily on the total wall and ceiling area, the number of rooms, the amount of prep work required, and the quality of paint selected. Rooms with high ceilings, intricate trim, or multiple colors require more labor time. Prep work including patching holes, sanding rough surfaces, caulking gaps, and priming bare or stained areas can account for a significant portion of the total labor hours on an interior paint job. Paint quality ranges from basic builder-grade products to premium formulations that offer better coverage, durability, and washability. The number of coats needed also affects cost, with most professional jobs requiring two coats of finish paint over a coat of primer on new or repaired surfaces.

Exterior painting involves additional considerations that affect both cost and project planning. Surface preparation is often more intensive on exteriors, potentially including pressure washing, scraping loose paint, sanding, caulking, and priming bare wood. The type of exterior surface matters as well, with smooth siding being faster to paint than textured surfaces like stucco or brick, which absorb more paint and require different application techniques. Access difficulty for multi-story homes increases labor costs due to ladder work, scaffolding, or lift equipment. Weather conditions limit the painting season in many regions and can affect scheduling and project duration. Trim, shutters, doors, and soffits are typically quoted separately from the main wall surfaces and often require more meticulous prep and application work.
