$2 to $6 per square foot of floor area for walls, or $1.50 to $4 per square foot of actual wall surface painted.

Labor is 75% to 85% of an interior painting bill. Upgrading to premium paint adds little to the total and often saves a coat.

One to two days per average room including prep, or three to five days for a whole 2,000 square foot home with a two- to three-person crew.
