Painters price an exterior by the square foot of paintable wall. The Exterior House Painting Cost Calculator measures it — perimeter × wall height, plus the gable triangles, minus about 15 sq ft per window and 20 per door — and multiplies by a professional all-in rate for your siding from HomeAdvisor's exterior painting guide (updated June 2026). That guide puts the average job at $3,178, most at $1,819–$4,551, or $1.50–$4 per square foot; by siding, vinyl $1.25–$3.00 (average $2.00), fiber cement $1.20–$3.20 ($2.20), wood $1–$3 ($2.00), engineered wood $1–$2 ($1.50), stucco $1.50–$4 ($2.70), brick $1.50–$4.50 ($2.80) and stone $2.40–$5 ($3.70). Extras: trim $1–$3 per linear foot, entry doors $100–$500, garage doors $200–$500, shutters $50–$150 and power washing $240–$400. A 40 × 30 ft house with 9 ft walls, two 6/12 gables, 10 windows and 2 doors has 1,295 sq ft to paint: $1,619–$3,885 in vinyl, typically $2,590.

HomeAdvisor (updated June 2026) puts the average at $3,178, with most homeowners paying $1,819–$4,551, or $1.50–$4 per square foot of paintable wall. On its table a two-story home of about 1,500–2,500 sq ft runs $3,000–$6,200, and a single-story home of 1,000–1,500 sq ft $1,500–$3,500.
Multiply the perimeter by the wall height, add the gable triangles and subtract windows and doors. HomeAdvisor uses about 12 sq ft per window and 21 per door; this calculator's house mode uses 15 and 20. A 40 × 30 ft house with 9 ft walls, two 6/12 gables, 10 windows and 2 doors has about 1,295 sq ft to paint.
Engineered wood ($1–$2 per sq ft, average $1.50) and concrete ($1–$3.50, average $1.90) on HomeAdvisor's table. Porous, rough surfaces cost the most: stucco averages $2.70, brick $2.80 and stone $3.70 per sq ft, because they take primer and extra paint.
$1–$3 per linear foot of trim on HomeAdvisor's figures, plus $100–$500 per entry door, $200–$500 per garage door and $50–$150 per shutter. Painting the gutters adds $200–$800 and power washing beforehand $240–$400.
Use the exterior paint calculator on this site: it divides the wall area by the coverage on the can for each coat. HomeAdvisor puts exterior paint at $20–$80 a gallon, so the paint itself is usually a small part of a professional quote — most of the price is prep and labor.
