Interior painting runs about $2–$6 per square foot of floor area, or roughly $2,000–$6,000 for a whole home. Prep work and trim are what move the number.
What affects the price
Prep & repairs
Patching, sanding, and priming add labor — often the biggest variable.
Ceiling height
Tall walls and stairwells need ladders or scaffolding.
Trim & doors
Cutting in trim, doors, and cabinets is slow, detailed work.
Paint grade & colors
Premium paint and multiple or dark colors (more coats) cost more.
