Calculator

sq ft

How it works

Paintable area × Tier rate × Region = Total

Your wall area is multiplied by the 2026 installed rate for the project type and tier — interior $2.50 / $3.75 / $5.25 per sq ft for basic, mid-range, and premium; exterior $2.00 / $3.00 / $4.00 — then adjusted for your region.

Materials ≈ 25% · Labor ≈ 75%

Painting is one of the most labor-heavy trades: prep, masking, application, and cleanup dominate the bill, while paint and supplies are roughly a quarter of the total.

The low–high range comes from each tier's published rate band, reflecting how quotes spread with surface condition and prep scope.

Worked example

1,500 sq ft of interior walls, mid-range paint:

1,500 sq ft × $3.75 = $5,625

Paint & materials (25%) = $1,406

Labor (75%) = $4,219

Range: $4,500 – $6,750

Budget around $5,625 for this project.

Painting quotes confuse people because the number everyone asks about — the paint — is the smallest part of the bill. On a professional job, 70 to 80 cents of every dollar pays for human hours: moving furniture, patching, sanding, masking, priming, cutting in, rolling, and cleaning up. The $60 gallon of paint is a rounding error next to two days of skilled labor.

This calculator prices your project the way contractors do: per square foot of paintable surface, with the labor-heavy split shown explicitly. Interior and exterior use different rate bands because spray rigs and scaffolding are a different business than brushes and drop cloths. Use the range to sanity-check bids — and remember that prep scope, not paint brand, is what usually separates the low bid from the high one.

How to measure for the house painting cost calculator

  1. Measure each wall: width × height, in feet. Add all walls together — this is paintable area, not floor area.
  2. Subtract roughly 20 sq ft for each door and 15 sq ft for each standard window to avoid overpaying.
  3. Decide the real scope before pricing: walls only is the base rate; adding trim, ceilings, and doors moves the quote toward the high end of the range.
  4. Note the wall condition honestly. Previous paint in good shape prices at mid-range; wallpaper removal, water stains, or bare drywall belong at premium.

Worked example: 1,500 sq ft interior, mid-range

Repainting 1,500 sq ft of interior wall area, mid-range paint tier, average-cost region:

  1. Paintable area: 1,500 sq ft (measured wall-by-wall, doors and windows deducted).
  2. Mid-range interior rate: $3.75/sq ft.
  3. Total: 1,500 × $3.75 = $5,625; region ×1.00 → $5,625.
  4. Paint & materials (25%): $5,625 × 0.25 = $1,406. Labor (75%): $5,625 × 0.75 = $4,219.
  5. Range: 1,500 × $3.00 = $4,500 low; 1,500 × $4.50 = $6,750 high.

Total $5,625 — about $1,406 in paint and materials and $4,219 in labor, with a realistic quote range of $4,500–$6,750.

Pro tips for painting quotes

  • Do your own prep to cut the bill: moving furniture, removing outlet covers, and light patching can shave 10–20% off labor.
  • Get the scope in writing — "two coats, walls only" versus "walls, trim, and ceilings" is a completely different price for the same rooms.
  • Buy the paint yourself only if the contractor allows it; most pros get 20–30% trade discounts you cannot, so their materials line is often cheaper than retail.
  • Never judge by the per-gallon price. A $70 gallon covering 400 sq ft in two coats is cheaper per finished square foot than a $40 gallon needing three.

How to use the house painting cost calculator

1. Measure your paintable wall area in square feet (walls only, not floor area) — or square meters in metric mode.

2. Choose interior or exterior — pricing bands differ because application methods and prep differ.

3. Pick a paint tier: basic (economy paint), mid-range (quality paint, standard prep), or premium (top-shelf paint, extensive prep).

4. Set your region cost level and click Calculate for a materials/labor split and a realistic quote range.

How house painting cost is calculated

The estimate multiplies your paintable area by the 2026 installed rate for the project type and tier — interior $2.50 basic / $3.75 mid-range / $5.25 premium per sq ft; exterior $2.00 / $3.00 / $4.00 — then applies the region multiplier.

The total splits into paint and materials (about 25%) and labor (about 75%), matching the national cost breakdown where prep and application dominate the bill. The low–high range reflects the published rate band for the tier, not a made-up margin.

What moves a painting quote the most?

Surface condition beats paint brand every time. Walls needing patching, wallpaper removal, or stain-blocking primer cost far more in labor than the upgrade from mid-range to premium paint. Ceiling height matters too — anything over 8 feet adds ladder and scaffold time.

Trim and ceilings are usually priced separately or push you toward the high end. If a quote seems high, ask exactly what is included: walls only, or walls plus trim, ceilings, doors, and closets.

House painting cost example

Repainting 1,500 square feet of interior wall area at the mid-range rate of $3.75 per square foot: 1,500 × $3.75 = $5,625.

Paint and materials (25%) come to about $1,406 and labor (75%) about $4,219. Expect contractor quotes for this scope to land between $4,500 and $6,750 in an average-cost market.

DIY vs. hiring a painter

DIY painting costs roughly $0.50–$1.50 per square foot in paint and supplies — the 25% materials slice of the professional price. For a single bedroom that is a few hundred dollars versus $400–$900 hired out.

The trade-off is time and finish quality: cutting clean lines, rolling without lap marks, and prepping properly takes far longer than most first-timers expect. A popular middle path is doing the prep (furniture, masking, patching) yourself and hiring the application.

Frequently Asked Questions

How much does it cost to paint a house per square foot in 2026?+
Professional interior painting costs $2.00 to $6.00 per square foot of paintable surface in 2026, while exterior painting runs $1.50 to $4.50 per square foot. A standard 12×12 bedroom typically costs $300 to $800; a full 1,500–2,000 sq ft home interior runs $3,000 to $9,000.
How do I measure paintable area?+
Measure each wall's width × height and add them up, then subtract about 20 sq ft per door and 15 sq ft per window. For a quick whole-house estimate, paintable wall area is roughly 2.5 to 3 times the floor area for rooms with 8-foot ceilings. This calculator takes paintable surface area directly.
Why is labor such a big share of painting cost?+
Labor is 70–80% of a professional paint job. The paint itself is cheap compared to the hours spent on surface prep — patching, sanding, caulking, masking, priming — plus the actual application. That is why doing your own prep work is the single biggest way to cut a painting quote.
Is exterior painting cheaper than interior per square foot?+
Usually yes per square foot — exterior runs $1.50–$4.50 versus $2.00–$6.00 interior — because exterior work uses faster spray application over large flat areas. But exteriors often need more prep (power washing, scraping, wood repair) and weatherproof paint, so total project costs are frequently higher.
How many coats of paint are included in these rates?+
The tier rates assume a standard two-coat professional job over a previously painted surface in decent condition. Bare drywall, dramatic color changes, or damaged surfaces needing skim-coating push costs toward the high end of the range.

Cost recouped — interior (editorial estimate)

Interior painting is among the highest-ROI low-cost projects — roughly 107% by one editorial estimate — but only when done flawlessly. It is the lowest-cost way to transform a room, and NAR notes fresh paint is "often recommended to sellers." Treat the figure as directional, not survey data.

  • Lowest cost per visual impact of any project
  • Fresh paint makes homes feel larger and cleaner
  • A weekend-scale project with same-week results
