Professional interior painting runs $2-$6 per square foot of floor area in 2026, or $4.70-$6.75/sqft for the full scope of walls plus trim plus ceilings per HomeGuide. A 2,000 sqft whole-house paint job lands at $5,500-$8,000 for walls-only in flat paint, $6,000-$10,000 with trim included, $9,400-$13,500 for walls plus trim plus ceilings, and $11,000-$18,000 for a complete interior with cabinet painting bundled. National average for single-job interior paint work sits at $2,022 per Angi, which reflects a typical 2-3 room residential project.
Labor dominates the cost structure at 70-85% of total because painting is pure hand-applied skilled work — prep, cut-in, rolling, drying, and second coat. That’s why regional labor rates swing totals dramatically. Materials are roughly 15% of total: paint and primer ($0.50-$1.20/sqft depending on brand and coverage), plus supplies (drop cloths, tape, rollers) at 4%. Prep work (patching drywall, sanding, masking) runs 12% of total and is the most commonly under-scoped line item in budget bids.

Then read on for the per-room cost breakdown, the nine factors that move your painter quote, and the real-quote checklist that separates a $3,000 legitimate bid from a $2,200 contractor who will nickel-and-dime prep add-ons mid-project. For companion drywall work that typically precedes paint, the drywall install cost calculator handles the previous trade.
