How much does it cost to paint a house interior?

Interior painting for a 2,000 sqft home costs $3,500–$8,500 in 2026 with professional labor, or $1,200–$2,500 in materials if DIY. Per-room pricing: small bedroom $250–$650, large bedroom $400–$900, kitchen $400–$1,000, full-height stairwell $500–$1,500. The biggest cost driver is ceiling-height — anything over 9 ft adds 25–50% per room because of staging. Trim, doors, and accent walls add 15–30% to a flat 'walls only' quote.
