Paint Cost Guide: Gallons, Labour & Project Price (2026)

This calculator estimates paint material cost for any wall area. Select your paint type for a default price per gallon, enter total wall area, choose your coat count, and get an instant material cost plus a professional painting price range. Deduct openings for a more accurate net area, or leave the deduction at zero for a conservative estimate.

What affects painting cost

Labour is the dominant cost in professional painting, typically 70-80% of the total bill. The biggest variables beyond room size are prep work (wall repairs and patching add $50-$200+), ceiling height (anything above 9 ft needs ladders or scaffolding and adds time), colour change (going from dark to light or vice versa usually needs primer plus 2-3 coats of finish), and surface texture (rough or previously unpainted surfaces absorb significantly more paint). Trim and ceiling painting are usually quoted separately and add $1-$3/linear ft for trim.

Professional painting cost by region: 2026 US averages

Paint itself is a nationally distributed product with broadly similar pricing across the country. What varies significantly is the cost of professional labour. Painter rates in Texas and the Southeast run well below rates in the Northeast and West Coast, where higher cost of living and in some markets union labour agreements push hourly rates up. For a DIY project the regional difference is minimal, but for a professionally painted job regional rates drive the final invoice more than any other factor.

Texas and Florida are consistently among the most affordable markets for professional painting in the US. A 1,500 sq ft house interior that might cost $4,500-$7,000 professionally painted in New York or Los Angeles typically runs $2,500-$4,500 in Houston or Dallas, with materials representing roughly the same cost in both markets. The Southeast broadly follows the same pattern, with a large supply of independent painting contractors keeping rates competitive.

In the Northeast and West Coast, licensed painters tend to charge more because the general cost of running a business, insurance, and labour is higher. Additionally, union painters are common in commercial and multi-family residential work in markets like New York and San Francisco, which pulls residential rates upward in the same labour pool. Getting painting quotes in January or February rather than in spring, when demand peaks, often produces better pricing in these markets.

Frequently Asked Questions

Professional interior room painting typically costs $300-$750 for a standard bedroom in 2026, or $1.50-$4/sq ft of wall area. A 12x12 ft room with 8 ft ceilings has about 384 sq ft of wall area. DIY material cost for the same room is typically $60-$150 for paint only. Regional variation is significant: Texas and the Southeast run 20-30% below the national average.
Calculate total wall area (perimeter × ceiling height), subtract windows and doors, multiply by coats, divide by 350 sq ft per gallon, and round up. A standard 12x12 ft room with 8 ft ceilings needs approximately 1.5-2 gallons for 2 coats. Enter your wall area and coats in the calculator above for an instant count.
Interior latex paint costs $25-$45/gallon (standard) and $50-$85/gallon (premium) in 2026. Exterior paint runs $30-$90/gallon. Primer costs $20-$40/gallon. The calculator auto-fills a default based on your type selection. Most painting projects use 1-5 gallons depending on room size and coats.
Professional painters typically charge $35-$75/hour for interior work in 2026, with most pricing jobs by the project rather than by the hour. Regional variation is significant: South Central and Southeast rates run $30-$55/hour, while Northeast and West Coast rates run $55-$90/hour. See the regional tables above for city-level estimates.
The calculator shows material cost only. The professional painting range in the results section includes typical labour plus materials. Labour is 70-80% of a professional painting job. Get local painter quotes for your specific project as labour rates vary significantly by region.
The material estimate excludes primer (typically a separate purchase for new drywall or colour changes), brushes, rollers, tape, drop cloths, wall patching and repairs, trim and ceiling painting, and furniture moving. The professional painting range excludes anything outside a standard 2-coat wall paint job. Get a written quote from your painter specifying exactly what is included.
