| Scope | Cost per sq ft of floor area | Typical total (1,500 sq ft) |
|---|---|---|
| Walls only | $1.50 to $4 /sq ft | About $2,250 to $6,000 |
| Walls and ceilings | $2 to $5 /sq ft | About $3,000 to $7,500 |

What drives interior painting cost
- Floor area, which scales with wall area to paint.
- Scope: walls only versus walls, ceilings, and trim.
- Number of coats and any color changes from dark to light.
- Wall condition, patching, and prep work.
- Ceiling height and trim detail.
- Paint grade and regional labor rates.
Key cost factors
Prep is the hidden cost
Patching, sanding, caulking, and priming take time and are often most of the labor. Smooth, well-maintained walls paint faster and cheaper than damaged or heavily textured ones.
Scope drives the number
Walls alone are the cheapest. Adding ceilings, trim, doors, and closets raises both labor hours and the total. Trim work in particular is slow and detailed.
Paint quality
Premium paint costs more per gallon but covers better, lasts longer, and can save a coat, which offsets some of the higher material cost.
