How Much Does It Cost to Paint a House Interior?
Interior painting runs $2 to $6 per square foot of paintable wall area in 2026, about $2.75 for walls only and $4.70 with trim and ceilings. Room-by-room planning ranges, prep costs, and the method behind the numbers.
Planning figures, not contractor quotes. How we calculate
Short answer
Interior painting costs $2 to $6 per square foot of paintable wall area in 2026, paint and materials included, per the HouseholdDecors planning method. Plan on about $2.75 per square foot for walls only, or about $4.70 when trim and ceilings are included. A typical bedroom runs $240 to $720 and a living room $700 to $2,000; sanding and patching can add about $0.50 to $0.75 per square foot where walls need repair.

What interior painting costs in 2026: the HouseholdDecors planning range
HouseholdDecors plans interior painting with a per-square-foot range, not a single national average. Our 2026 Cost Index lists professional interior painting at $2 to $6 per square foot of paintable wall area, paint and materials included, with $2.75 as the walls-only planning point. Where a project lands in that band is mostly scope: walls alone sit at the low end, and adding trim and ceilings moves the rate to about $4.70 per square foot.
| What the quote includes | Installed rate |
|---|---|
| Walls only | about $2.75 per square foot |
| Walls, trim, and ceilings | about $4.70 per square foot |
One outside cross-check: HomeAdvisor's 2026 project data reports a national average of $2,022 for an interior painting project, with most homeowners paying $965 to $3,089 and the full range running $350 to $5,800. We cite it as a single data point inside the planning range, not as the headline: an average cannot price your rooms, and it hides the scope split in the table above. The room-by-room ranges in the next section are the more useful planning tool.

Interior painting cost by room type
Room size is the biggest factor behind the total, per HomeAdvisor, because each room carries a different square footage. The table below uses that article's room figures; the square footages are the room sizes HomeAdvisor priced, and the ranges scale with the $2 to $6 per square foot band.
| Room type | Room size | Average price range |
|---|---|---|
| Bathroom | 70 sq ft | $140 to $420 |
| Bedroom | 120 sq ft | $240 to $720 |
| Kitchen | 160 sq ft | $300 to $960 |
| Dining room | 300 sq ft | $600 to $1,200 |
| Living room | 330 sq ft | $700 to $2,000 |
Small rooms cost less because they are small, not because the per-square-foot rate drops: the living room is usually the largest room in the home and costs more to paint, per HomeAdvisor.

Interior painting cost by size
Using paintable wall area, 500 square feet produces a base planning range of $1,000–$3,000; 1,000 square feet produces $2,000–$6,000; 1,500 square feet produces $3,000–$9,000; and 2,000 square feet produces $4,000–$12,000. These examples multiply the preserved $2–$6 range rather than introducing a new price claim.
Do not substitute home floor area for paintable wall area. Doors, windows, room geometry and which surfaces are included can make the two measurements very different. For the most-searched project size, see the cost to paint a 2,000 sq ft house interior with room-by-room math.

Labor and material scope
The accepted commercial source says labor commonly represents 75%–95% of total painting cost. Our breakdown preserves that broad share instead of converting employee wages into contractor billing rates.
The public calculator does not show a paint-dollar component. The available $15–$40 gallon statement does not identify exact current products or clearly define quality, primer, tax and supplies; manufacturer coverage data alone cannot repair those gaps. The remainder is left unallocated rather than being invented as overhead, supplies or profit.

Preparation factors
When walls require sanding and patching, the reviewed source reports an additional $0.50–$0.75 per square foot. The calculator adds this only when selected. Major drywall repair, water damage, mold treatment and lead-safe work are outside that allowance.
Special features change the bill separately from prep: HomeAdvisor reports that painting an accent wall can increase project costs by 20% to 30% for the additional paint and materials, while custom murals run $1,000 to $2,000 because they need specialized labor. Textured walls can require double the paint of smooth walls, driving costs up by as much as 50%, so factor the extra surface area into your square footage.

Finish and quality
Paint type and sheen can change material cost, but the reviewed evidence does not support separate installed low-, standard- and premium-finish multipliers. For that reason, finish quality is not an input in this calculator.
For materials planning, HomeAdvisor reports that one gallon of paint covers about 350 square feet, so a 2-gallon can covers up to 800 square feet for two coats in an average-sized room, and an average-sized house takes about 6 gallons per coat. Primer costs about $10 per gallon and covers roughly 100 square feet per coat. Most paint gallons run $15 to $40, with flat paint about $13, semi-gloss about $17, and high-gloss enamel or VOC-free paint about $35.

Worked example
For 1,000 square feet of paintable wall area with no separate repair allowance, the model returns $2,000 low, $2,750 typical and $6,000 high. If sanding and patching are required across the full area, the supported allowance adds $500–$750, producing $2,500 low, $3,380 typical and $6,750 high.
Painting the outside too? Budget the exterior separately, since exterior rates run $1.50 to $4.00 per square foot of paintable surface area in 2026, and a stucco exterior averages about $4,500 with most projects between $3,600 and $7,200. Our exterior house painting cost guide breaks down home-size totals, siding factors, and prep costs.

Limitations
The $2–$6 installed range relies primarily on one commercial marketplace dataset and remains MEDIUM confidence. An independent estimating publication provides transparent unit-cost methodology but does not validate this complete whole-project range. This is a broad planning range, not an authoritative national benchmark.
Contractor quotes and local labor or material conditions vary. Trim, ceilings, unusual access, extensive repairs, structural issues, hazardous materials and moving contents can materially change cost. No ZIP, city or state multiplier is used.

Frequently asked questions
How much does a painting project cost?
Interior painting costs $2 to $6 per square foot of paintable wall area in 2026, paint and materials included, per the HouseholdDecors planning method. Plan on about $2.75 per square foot for walls only, or about $4.70 when trim and ceilings are included. A typical bedroom runs $240 to $720 and a living room $700 to $2,000; sanding and patching can add about $0.50 to $0.75 per square foot where walls need repair.
Why is there a cost range instead of a single price?
Project costs move with scope, finish level, and local labor rates. This guide splits the national planning range into low, typical, and high levels, and the scope sections explain what pushes a project toward each end. Use the range to budget, then collect itemized contractor quotes for your exact project.
Are these figures contractor quotes?
No. They are national planning ranges compiled from published, cited sources, shown with their assumptions and limitations. Treat them as a budgeting starting point, not a bid. Our methodology page explains how every figure is sourced and reviewed.
