A full interior repaint on a 1,500 to 2,500 sq ft home typically runs $3,000 to $8,500. Contractors price from paintable wall surface rather than floor square footage, which is why two homes with identical floor plans can quote differently once you account for ceiling height, trim detail, and how many coats the color change requires.
Quick Reference: Interior Painting Costs
- Whole-home range: $3,000 to $8,500 for 1,500-2,500 sq ft.
- Per room, walls only: commonly $300 to $800 depending on size and height.
- Walls, ceiling, and trim together: expect roughly double a walls-only room price.
- Doors and trim: slow detail work, often the largest single line item after walls.
Note: these are 2026 regional averages. Final pricing always comes from an on-site assessment.
How Contractors Calculate Interior Pricing
Estimators work from either total floor square footage or actual paintable wall area, and the second is more accurate. Standards from the Paint and Decorating Contractors of America define how that surface is measured and what a standard scope includes.
Paintable surface means wall area minus windows and doors, plus ceilings if they are in scope, plus the linear footage of trim. Our post on how much paint you need walks the same math from the material side.
Room Size and Ceiling Height
Going from 8-foot to 10-foot ceilings adds 25 percent more wall surface and usually requires staging, so it moves labor more than the surface math alone suggests. Vaulted and two-story entry walls add access cost on top of that.
Occupied rooms cost more than empty ones. Moving and covering furniture, protecting floors, and working around a household all add time to the same square footage.
What Changes an Interior Estimate
- Color change severity: dark to light needs a tinted primer plus extra coats.
- Wall condition: patching, skim coating, and priming repairs are separate labor.
- Trim package: crown molding, chair rail, built-ins, and panel doors are detail work.
- Ceilings: often quoted separately, and popcorn texture changes the approach entirely.
- Sheen: higher sheens demand better surface prep, which costs more than the paint does.
Choosing sheen room by room? See our guides on satin and matte finishes. For damaged walls, our drywall repair service handles the prep.
Common Questions About Interior Painting Costs
Do painters do trim or walls first?
Trim and doors first, then mask them and roll the walls. Cutting walls to already-finished trim gives a crisper line than the reverse and avoids roller spatter on fresh enamel.
Is it cheaper to paint before moving in?
Noticeably. An empty house needs no furniture moving or protection, crews work continuously, and spraying becomes practical, which is faster than rolling.
Should ceilings be painted too?
If they have not been done in years, yes — fresh walls make a dingy ceiling obvious. It adds cost but doing it later means masking finished walls all over again.
How long does a whole-house interior take?
Typically 3 to 7 working days for an average home, depending on scope, occupancy, and how much prep the walls need.

The fastest way to a real number is a walkthrough: ceiling heights, trim package, wall condition, and color change decide the price far more than square footage does.
