How This Calculator Works
This interior painting cost calculator estimates your total project cost from four inputs: project size, quality tier, the options you select, and your location. It combines material and labor rates for your chosen tier, adds typical permit costs, then applies a regional cost multiplier so the estimate reflects pricing in your state.
Estimates use 2026 cost data cross-referenced from multiple industry sources. Treat the result as a planning range, not a quote. Your final price depends on your specific scope, material choices, and local contractor availability, so collect at least three itemized bids before you set a budget.
What Affects Your Interior Painting Cost
Prep Work
$500 - $4,000Prep eats 30-50% of a painter's labor time. Walls in good shape need just a quick wash and light sanding. Walls with cracks, nail holes, peeling paint, or water stains need patching, skim coating, sanding, and priming - all before a single coat of color goes on. A home with wallpaper removal can add $1-$3 per square foot on top of painting costs.
Ceiling Height and Layout
$0 - $3,000+Standard 8-foot ceilings are the baseline. Vaulted or cathedral ceilings (10-20 feet) add 25-50% to labor costs because of scaffolding setup and slower work at height. Stairwells with tall walls are especially expensive. Lots of windows, doors, and built-ins also slow painters down due to cutting-in and taping.
Number of Colors
$200 - $1,500Every color change means stopping, cleaning tools, masking edges, and starting again. A whole-house job with one color throughout is significantly faster than painting each room a different color. Accent walls add $50-$150 per wall in labor. If you want 8 different colors across your home, expect to pay 15-25% more than a single-color job.
Paint Quality
$200 - $2,000 for a whole houseBuilder-grade paint runs $15-$25 per gallon and requires more coats for solid coverage. Mid-range paints like Behr Marquee or PPG Diamond cost $30-$50 per gallon and cover in fewer coats. Premium paints from Benjamin Moore (Regal, Aura) or Sherwin-Williams (Emerald, Duration) run $50-$80+ per gallon but offer superior coverage, washability, and durability. A typical 2,000 sq ft home needs 15-25 gallons.
Surfaces Included
$2,000 - $8,000Walls-only is the cheapest option at $2-$6 per square foot of floor space. Adding ceilings increases cost by 30-40%. Trim, baseboards, crown molding, and door/window casings add another $1-$3 per linear foot. Painting interior doors adds $75-$150 per door. A full-scope job (walls, ceilings, all trim, doors) can cost 2-3 times a walls-only quote.
