Cost to Paint a 1,500 Sq Ft House

What Does It Cost to Paint a 1,500 Sq Ft House?

For a 1,500 sq ft home, an interior-only repaint typically runs $2,400–$5,600. An exterior-only repaint typically runs $2,800–$6,500, and a full interior plus exterior job typically runs $5,500–$11,500. These are national ranges for the average cost to paint a house; your number will move with regional labor markets, surface condition, ceiling height, number of colors, and prep scope more than with the square footage itself.

The single biggest swing factor is the difference between a repaint and a full prep-and-paint job. A repaint assumes the same color, a sound substrate, and minimal patching — you wash, spot-prime, and roll two coats. A full prep-and-paint job adds scraping, sanding, caulking, stain blocking, and sometimes a full primer coat, and that distinction alone can double the price.

One caution before you price anything: 1,500 sq ft of floor area is not 1,500 sq ft of wall area. Floor area is only the starting point for a takeoff, not the quantity you price. If you bid off floor area alone, you will underprice trim, doors, ceilings, and prep — the items that actually drive the cost to paint house interior and the cost to paint house exterior.

The rest of this article breaks the number into measurable pieces: wall area, trim, doors, prep, labor hours, and material gallons. If you would rather hand the takeoff to a specialist, our painting estimating services produce bid-ready quantities and pricing you can defend.

Floor Area vs. Paintable Wall Area on 1,500 Sq Ft

The standard estimating method starts with a multiplier: paintable wall area ≈ floor area × 2.5 to 3.0 for a typical single-story home with 8 ft ceilings and a normal room count. The multiplier varies because more small rooms means more wall per square foot of floor, while open plans and large windows reduce wall area. This is the first step in any reliable how to estimate painting cost workflow.

Example — gross wall area for a 1,500 sq ft home:

1. Start with floor area: 1,500 sq ft.
2. Apply the mid-range multiplier: 1,500 × 2.7 = 4,050 sq ft of gross wall area.
3. Subtract openings. Windows and doors typically equal 12–18% of gross wall area. At 15%: 4,050 × 0.15 = 607.5 sq ft.
4. Net paintable wall area: 4,050 − 607.5 = 3,442.5 sq ft.

Ceiling height changes the result. At 9 ft ceilings, wall area rises roughly 12–13% over 8 ft; at 10 ft, roughly 25%. So the same 1,500 sq ft plan at 10 ft ceilings gives about 4,050 × 1.25 = 5,062.5 sq ft gross, or roughly 4,303 sq ft net after openings.

Ceiling area is separate. A 1,500 sq ft home has roughly 1,500 sq ft of ceiling if you paint it, minus closets and areas you skip. A quantity takeoff service measures each surface rather than relying on a multiplier, which matters when room counts or ceiling heights are unusual.

Interior Painting Cost for a 1,500 Sq Ft House

Interior interior painting cost 1500 sq ft pricing breaks into four measurable units: walls, ceilings, trim, and doors. Each carries its own unit of measure, so a formal estimate never lumps them into one square-foot number.

The baseline for cost to paint house interior work is two coats of latex over a properly primed or previously painted surface. Oil-based paint or a shellac-based primer for stain blocking adds both material and labor, and it usually requires a longer recoat window.

Sheen choice — flat, eggshell, satin, semi-gloss — affects price only slightly. But higher paint finish sheen shows drywall flaws, so it often forces more sanding, patching, and a skim coat in bad areas. In a formal estimate these line items belong under CSI MasterFormat Division 09 (Finishes) — 09 90 00 Painting and Coating. Our interior and exterior finishes estimating team prices them that way, and we coordinate with drywall takeoff when patching scope is unclear.

Exterior Painting Cost for a 1,500 Sq Ft House

Exterior painting is priced off wall area, not floor area. Measure the perimeter of the footprint, multiply by wall height, subtract openings larger than about 10 sq ft, then add gable ends and any detached garage or shed walls that get painted. On a 1,500 sq ft single-story home, that wall area usually lands between 1,400 and 1,800 sq ft depending on how broken up the footprint is and how many gables you have. A simple rectangle with two gables sits near the low end; an L-shape with a front-facing gable and a covered porch pushes toward the high end.

For exterior painting cost 1500 sq ft, typical U.S. ranges run about $1.75 to $4.00 per sq ft of wall area for a repaint. That puts a 1,500 sq ft wall-area job somewhere around $2,600 to $6,000 before you add major carpentry or siding repair. The cost to paint house exterior climbs fast on stucco and brick, because both surfaces are textured and absorbent, so they drink more paint and often need a masonry-specific primer. Siding is usually the cheapest substrate to paint. Wood and fiber cement hold paint well, and vinyl accepts a 100% acrylic latex system without a primer if it is clean. If your scope includes repairing or replacing siding, run the quantities through siding estimating services so the paint number does not absorb carpentry costs it should not carry.

Prep is the biggest variable on any exterior repaint. Pressure washing removes chalk, dirt, and mildew, but the surface must dry before coating. Scraping loose paint, sanding feathered edges, caulking joints and penetrations, and masking windows, doors, and fixtures can consume more hours than the actual spraying or rolling. A house with peeling south and west walls can double the prep budget compared with a house that only needs a wash and spot prime. When you are pricing the full exterior, remember that the cost to paint trim and doors is often quoted separately, so keep those linear-foot quantities in their own line item rather than burying them in the wall-area rate.

Exterior paint is typically 100% acrylic latex for siding and masonry. Oil-based and alkyd products still show up on primed metal and some specific substrates, but waterborne acrylics dominate because they stay flexible and resist mildew. On stucco, budget for a masonry primer and a heavier spread rate. If your exterior is EIFS or stucco, stucco and EIFS estimating services can separate the coating scope from any crack repair or substrate work. Before you buy material, calculate how much paint do i need by dividing the paintable wall area by the coverage per gallon, then add a waste factor for spray loss and touch-up.

The Painting Cost Formula Estimators Actually Use

1. Start with the total cost formula. Total Cost = (Labor Hours × Labor Rate) + Material Cost + Equipment + Subcontractor + Overhead & Profit. Every painting estimate is a variation of this. If you cannot fill in each line, you are guessing, not estimating.

2. Build labor hours from production rates. Labor Hours = Quantity ÷ Production Rate, then adjust for surface condition, height, and access. A two-coat repaint on smooth interior walls runs about 150 to 250 sq ft per hour. Ceilings run 100 to 180 sq ft per hour. Trim runs 20 to 40 linear feet per hour. Exterior walls run 100 to 200 sq ft per hour depending on prep. Rough texture, 12-foot ceilings, and scaffolding all push the rate down, which raises hours. For the cost to paint trim and doors, use the same logic but with linear-foot or per-door production rates, because those items are priced by count or length, not by wall area.

3. Multiply hours by the labor rate. Labor Cost = Labor Hours × Labor Rate. Rates vary widely by region and crew type. A residential painter in a low-cost market might bill $35 to $55 per hour, while a union or commercial crew can bill $65 to $95 per hour. Use the rate your crew actually carries, including burden. For a deeper breakdown of burdened rates, see labor cost estimating services.

4. Calculate gallons of paint. Gallons of Paint = (Paintable Area × Number of Coats) ÷ Coverage per Gallon. Most interior latex covers 350 to 400 sq ft per gallon per coat on smooth drywall. Exterior acrylic on siding covers roughly 300 to 350 sq ft per gallon. Then add a waste factor of 5% to 10% for touch-up, spray loss, and color changes. This step answers how much paint do i need for each substrate and sheen, so you can order material without overbuying.

5. Add material, equipment, and subs. Material Cost = Gallons × Price per Gallon, plus caulk, tape, plastic, sandpaper, and patching compound. Equipment covers sprayers, ladders, and lifts. Subcontractor covers any specialty coating or drywall repair outside your crew. If you need a clean material list before pricing, run the quantities through material takeoff services.

6. Apply overhead and profit last. Overhead & Profit is a percentage of the subtotal, typically 10% to 20% for a painting contractor. Apply it after labor, material, equipment, and sub costs are totaled, never to a single line in isolation.

Worked Example: Interior Repaint of a 1,500 Sq Ft Home

Example only — not a quote. This walkthrough shows the arithmetic for a standard interior repaint. Your quantities and rates will differ.

Assumptions: 4,050 sq ft of wall area, 1,500 sq ft of ceiling, 280 linear feet of baseboard, 120 linear feet of crown molding, and 8 interior doors. Labor rate $50 per hour. Paint price $45 per gallon.

Labor hours

• Walls: 4,050 sq ft ÷ 200 sq ft/hr = 20.25 hours
• Ceilings: 1,500 sq ft ÷ 140 sq ft/hr = 10.71 hours
• Trim: 400 lf ÷ 30 lf/hr = 13.33 hours (280 lf baseboard + 120 lf crown molding = 400 lf)
• Doors: 8 doors × 0.75 hr = 6.00 hours
• Total labor hours = 20.25 + 10.71 + 13.33 + 6.00 = 50.29 hours

Labor cost: 50.29 hr × $50/hr = $2,514.50

Paint quantities

• Walls: 4,050 sq ft × 2 coats ÷ 350 sq ft/gal = 23.14 gal
• Ceilings: 1,500 sq ft × 2 coats ÷ 350 sq ft/gal = 8.57 gal
• Trim: 400 lf × 0.05 gal/lf = 20.00 gal
• Total gallons = 23.14 + 8.57 + 20.00 = 51.71 gal

Paint cost: 51.71 gal × $45/gal = $2,326.95 With 8% waste factor: $2,326.95 × 1.08 = $2,513.11

Prep and consumables: caulk, tape, plastic, sandpaper, patching compound = $350.00

Subtotal: $2,514.50 + $2,513.11 + $350.00 = $5,377.61

Overhead and profit at 15%: $5,377.61 × 0.15 = $806.64

Total estimate: $5,377.61 + $806.64 = $6,184.25

That works out to roughly $4.12 per sq ft of floor area. The same formula scales to any size home once you have accurate wall, ceiling, and trim quantities. If you want a second set of eyes on your quantities before you submit, painting estimating services can check the takeoff and the labor build-up.

How Much Paint Do You Need for 1,500 Sq Ft?

Before you price a paint job, you need a defensible material quantity. The standard planning figure is that one gallon of latex paint covers roughly 350–400 sq ft per coat on a smooth, primed surface. On textured surfaces such as heavy stucco, brick, or rough-sawn wood, coverage drops to about 250–300 sq ft per gallon because the profile absorbs and traps more product.

The formula is straightforward: gallons = (paintable area × number of coats) ÷ coverage per gallon. Round the result up to the nearest whole gallon, then add a waste factor of 5–10% for touch-ups, roller loss, and color changes. If you need help turning plans into those areas, a material takeoff service can produce the wall and ceiling quantities you plug into the formula.

Here is a quick example. A 1,500 sq ft home with 4,050 sq ft of paintable wall area, two coats, and 375 sq ft per gallon: 4,050 × 2 = 8,100 sq ft of coated surface. 8,100 ÷ 375 = 21.6 gallons, which rounds to 22 gallons. Add 10% waste: 22 × 1.10 = 24.2, so buy 24 gallons for the walls.

Primer is a separate line item. New drywall, bare wood, and patched areas need a primer coat, which roughly adds one full coat of material and labor to the budget. Buying in 5-gallon buckets usually lowers the per-gallon price, but only if you can use the full container on the same project and color.

Labor vs. Material: Where the Money Goes

On a typical residential repaint, labor makes up 70–80% of the bill and material accounts for 20–30%. That split is why two bids for the same house can differ by thousands of dollars even when both contractors buy the same paint. The painting labor cost per hour you see on an invoice is not the painter's wage — it is a billed rate that carries the crew's productive time plus the contractor's overhead.

Several things drive the labor number. Prep time is the biggest variable, followed by the number of coats, height and access, masking and drop cloths, and the number of colors. A two-story foyer with a 20 ft ceiling needs scaffolding or an extension ladder, and that access time is billed even though no paint is applied. Switching between three or four colors adds cleaning, reloading, and cutting-in time on every transition.

Material cost is more predictable. Paint prices vary by brand, sheen, and quality tier, but the gallons of paint needed is a function of area and coats, not of how fast the crew works. A labor rate that looks high may simply reflect a contractor carrying insurance, vehicles, equipment, and office staff. On commercial or multi-family work, prevailing wage and union rates can push labor to 85% of the total, which is why labor cost estimating services separate wage components from burden and overhead.

For a firm that bids both residential and commercial paint scopes, the same logic scales up. A commercial estimating service will price production rates by substrate and access condition rather than applying one blended square-foot rate to every wall.

Prep Work: The Hidden Cost Driver

Prep is where painting estimates are won or lost. An estimator who prices only paint and labor will miss the steps that actually determine whether the coating stays on the wall. Include every step that applies to the substrate:

• Pressure washing. Required on exterior surfaces to remove chalk, dirt, mildew, and loose material. Paint over a dirty surface and you buy a premature failure.
• Scraping and sanding. Loose and peeling paint must come off, and sanding feathers the edges so the patch does not telegraph through the finish coats.
• Caulking. Joints at trim, windows, doors, and siding get a paintable sealant. This is a material and labor line, not a courtesy.
• Patching drywall. Nail pops, cracks, and holes get filled, taped if needed, and sanded before primer.
• Masking. Floors, windows, hardware, and adjacent finishes get protected. Masking time scales with the number of rooms and the amount of trim.
• Drop cloths. Canvas or plastic over finished floors and landscaping. Moving and resetting them between rooms adds hours on a full repaint.

Skipping prep is the most common reason a paint job fails early. Peeling, blistering, and poor adhesion almost always trace back to moisture, contamination, or a surface that was never sanded or primed.

Budget prep as a separate range. Light prep typically runs $0.25–$0.50 per sq ft. Heavy prep — lead-safe work, extensive scraping, multiple drywall patches — can run $1.00–$2.50 per sq ft or more. Homes built before 1978 may require lead-safe practices under EPA RRP rules, which adds containment, cleaning verification, and certified labor. On exteriors, prep often includes replacing rotted trim or siding, and that is a carpentry line item, not a painting line item. Restoration scopes follow the same discipline, which is why insurance restoration estimating treats prep and substrate repair as separate cost codes. On a remodeling project, the same separation keeps painting from absorbing drywall and carpentry costs that belong elsewhere.

Interior vs. Exterior Painting Cost Comparison

The table below compares typical U.S. cost ranges for interior and exterior painting of a 1,500 sq ft home. Use it as a planning benchmark, not a bid. Regional labor rates, access constraints, and surface condition will move these numbers.

Exterior work often costs more per square foot because prep is heavier, ladders and lifts add labor, and weather exposure shortens the paint life. Interior work has more linear feet of trim and doors, which are priced per unit rather than per square foot. A 1,500 sq ft home can have 600–900 linear feet of baseboard and crown molding, plus 8–14 doors, so those line items drive a large share of the interior total. If you need a bid-ready number instead of a range, a painting estimating service can produce a takeoff from your plans.

How Cost Varies by Region and Project Type

Labor rates are the biggest regional variable in any painting estimate. A painter in a rural area might bill $35–$50 per hour, while in a major metro the same work bills $60–$90 per hour. That spread flows straight into the average cost to paint a house and into every painting cost per square foot you calculate. Material costs are more uniform nationally, but they can still vary by 10–15% depending on local suppliers and brand availability.

Project type matters just as much. A rental turnover repaint is priced for speed and durability, so crews use production-grade coatings and move fast. A custom home repaint may include faux finishes, specialty coatings, or high-end trim, which changes both the material cost and the labor rate. Multi-family and commercial painting use different production rates and often require prevailing wage or union labor, which can push the painting cost for contractors well above residential benchmarks. For those scopes, multi-family estimating services apply the right wage and productivity assumptions.

National ranges are a starting point, not a bid. A location-based cost index or a professional estimating service can adjust them to your market. You can check regional multipliers on our construction estimating locations page or send plans for a same-day quote.

Common Mistakes When Estimating Painting Cost

• Using floor area as paint area. The most common error in how to estimate painting cost is treating 1,500 sq ft of floor as 1,500 sq ft of wall. Wall area is roughly 2.5–3.5 times floor area after deducting openings. Measure each room.
• Ignoring ceiling height. A 9 ft ceiling adds about 12.5% more wall area than an 8 ft ceiling in the same footprint, and it adds labor for ladders and edge work. High ceilings can push labor 15–25% higher.
• Underestimating prep time. Scraping peeling exterior paint or repairing drywall damage can take longer than applying the finish coats. Budget prep as a separate line item, not a percentage.
• Skipping the waste factor. Paint coverage is theoretical. Add 5–10% for touch-ups, roller loss, and second-coat overlap. Without it, you make mid-job material runs and eat the cost or issue a change order.
• Using the wrong production rate. A fast two-person crew and a single painter have very different square feet per hour. A crew might cover 300–400 sq ft per hour on walls; a solo painter might cover 150–200. Match the rate to the actual crew.
• Leaving out overhead and profit. Material, labor, and prep are direct costs. Overhead and profit typically add 15–25% on top. Skip them and a profitable job becomes a break-even one. Have a second set of eyes check the math with an estimate review service before you submit.

When to Use a Professional Painting Estimate

A professional painting estimate or takeoff earns its keep when the job is large, complex, or bid competitively. If you are a general contractor or painting subcontractor submitting a hard bid, a hand-built painting estimate template or a quick painting cost calculator will not hold up under scope review. The same is true when an owner asks you to justify a number line by line.

Watch for these triggers: three or more wall colors plus trim and ceiling colors, ceilings above 10 feet, extensive prep such as scraping, sanding, or patching more than 20% of the surface, historic or specialty finishes like limewash, Venetian plaster, or faux wood graining, and a deadline that forces overtime or a second crew. Any one of these can swing labor hours by 30% or more, and a unit-price guess will miss it.

A professional takeoff breaks the work into CSI MasterFormat Division 09 line items: 09 90 00 Painting and Coating, 09 91 00 Painting, 09 93 00 Staining and Transparent Finishing, and 09 96 00 High-Performance Coatings. That structure lets you defend your painting cost for contractors, show your client where the money goes, and compare bids apples to apples. A GC reading your proposal should see square footage, coats, prep allowance, and material brand in one place.
