Interior Painting Cost Calculator
Estimate US interior painting costs from paintable wall area and selected scope.
How this estimate is calculated
Paintable wall area is the baseline, not floor area. Wall condition, paint specification, ceilings, and trim are modelled as per-square-foot scope adjustments; major repair remains a fixed project allowance.
This is a planning estimate, not a contractor quote. Actual contractor quotes vary by location, specification, site conditions, labour, and project requirements.
Useful cost information
Planning assumptions
- The estimate assumes accessible occupied rooms and normal numbers of coats.
- Wallpaper removal, lead-safe work, major plastering, and extensive furniture moving are excluded.
