How Much Does It Cost to Paint a House Interior in 2026?

National ranges, materials + labor, interior only · Pricing data updated 2026-07-05 · Reviewed annually

A professional walls-only interior repaint runs about $1,000 to $3,500 for a 2BR condo (~1,000 sq ft), $1,750 to $5,500 for a 3BR single-story (~1,600 sq ft), and $2,750 to $8,250 for a 4BR two-story — materials and labor included. Add ceilings, trim, and doors and each total rises 60–90% (a 3BR jumps to $2,750–$10,250 for the full all-surface scope).

One number causes most of the confusion: consumers and every major cost site quote painting per square foot of floor area, but painters actually price the wall surface — and there are about 2.8× more square feet of wall than floor at an 8-ft ceiling. This page leads with floor-area cost (how you search) and exposes the wall-area basis so it reconciles with the free interior paint calculator that computes gallons from wall area.

Floor area vs. wall area: reconciling the two prices

This is the single most important thing to understand before you compare quotes. The same job can be quoted three ways — and they all describe the same walls.

A 10×12 room is 120 sq ft of floor but roughly 300 sq ft of paintable wall (perimeter 44 ft × 8 ft, minus ~15–20% for doors and windows). Higher ceilings raise the multiplier proportionally. When two guides look like they disagree by 3×, they're almost always quoting different bases — not different jobs.

Cost to paint by room

Per-room costs run higher per square foot than a whole-home job — small rooms carry the same setup, cut-in, and cleanup over less area. Walls only unless noted.

Whole-home cost by size and scope

Installed, national averages, standard prep. Each cell is a low-to-high range; real projects cluster toward the middle. Walls-only is the default scope — adding ceilings, then trim and doors, is what drives the 60–90% jump across the row.

These are walls-only at standard prep. Fixr and Homewyse publish whole-home totals 2–3× higher — those bundle full prime-and-paint of every surface in high-grade paint with general- contractor markup, a different (and much larger) scope. This page models the walls-only repaint that most people actually search for.

What each surface adds

Walls are the base; these are the opt-in line items on top. Each is priced on its own basis so it can be added to any scope.

Each additional coat beyond the standard two adds roughly $50–70 per 300–400 sq ft. Dark-to-light and saturated accent colors commonly need a third coat.

Paint quality: where premium pays off

Because labor is 70–85% of a professional bid and paint is only ~15–20%, moving from contractor-grade to premium adds only ~$500–1,000 to a whole-house job. Cheaper paint won't meaningfully lower the bill — pick paint on performance, not price.

Cost by region

Interior painting price swings by region are driven almost entirely by labor rates — not paint cost. The same 3-bedroom walls-only repaint across regions:

Within a single metro the spread can be as wide as between regions — downtown pricing runs well above the same job an hour out. Older Northeast and Upper-Midwest housing stock adds pre-1978 lead-safe jobs, and off-season booking (November–February) commonly saves 10–20%.

Wallpaper removal: the budget-killer

Wallpaper removal is not a multiplier — it's its own per-room job that runs before any paint goes on. Stripping is about $0.60–$3/sq ft; a 12×12 room averages around $550, with soak-and-scrape or multi-layer paper pushing to $3–8/sq ft. Budget $200–$1,200 per room and toggle it on in the estimator above.

Pre-1978 homes: lead-safe (RRP) work

Interior work that disturbs more than 6 sq ft of painted surface per room in a home built before 1978 triggers the EPA RRP Rule (40 CFR Part 745) — sanding is the specific trigger. A paid contractor must be lead-safe certified and use containment and HEPA cleanup, adding roughly 10–20% to cost and 1–2 weeks to the timeline (lead testing runs $30–$600). Homeowners doing their own work are exempt but should still follow lead-safe practices. Civil penalties are steep — verify the current 40 CFR §19.4 schedule before relying on any figure.

DIY vs. hiring a pro

Interior painting is the most DIY-friendly trade precisely because labor is most of the cost — doing it yourself captures that 70–85%. Materials-only budgets (paint, primer, supplies; excludes your time):

A single 10×12 room is about $100–$350 in materials (2–3 gallons) and 6–16 hours of work. Plan on 300–400 sq ft per gallon per coat on smooth walls (textured pulls to 250–300); popcorn ceilings need 20–30% more.

What these ranges don't include

National ranges, materials + labor combined, professional application. The base rate is for WALLS ONLY with two coats at 8-ft ceilings — ceilings, trim, doors, closets, and accent walls are opt-in scope priced separately, and prep (patch vs. skim-coat), ceiling height, occupied vs. empty, and pre-1978 lead-safe work are shown as adjusters. Excludes cabinet painting, texture application/removal, murals and decorative finishes, drywall repair beyond patching, wallpaper removal (its own line below), and all exterior work. These are planning ranges, never a quote — get at least three written, itemized bids from licensed local painters.

• Kitchen cabinet painting — Different trade, different price — degrease, sand, prime, spray with cabinet enamel ($30–60/LF or $2,000–6,500/kitchen). See the kitchen-cabinet cost page.
• Drywall repair beyond patching — Holes, large cracks, and water damage are a separate repair line (~$300–900, avg $600).
• Texture application or removal — Popcorn removal ($1–2/sq ft scrape; up to $14–20+/sq ft to a level-5 smooth finish), skim-coating, and re-texturing are their own trades.
• Murals & decorative / specialty finishes — Venetian plaster, faux, stenciling, trompe l’oeil ($35–150/sq ft; murals $1,000–2,000).
• Asbestos or lead abatement — Distinct from RRP lead-safe painting — licensed remediation only.
• Exterior anything — Siding, exterior trim, doors, decks, fences, garages — see the exterior painting cost page.

Where these numbers come from

Ranges reconcile the consumer cost aggregators that set installed pricing — Angi, HomeAdvisor, HomeGuide, Forbes Home, Improovy, Taskrabbit — anchored to the walls-only ($2.75/sq ft) and all-surface ($4.70/sq ft) figures HomeAdvisor's 2026 guide publishes, cross-checked against PCA production rates (~85 sq ft/hr, two coats). Where sources diverged by more than 40% it was almost always a floor-area-vs-wall-area basis gap or a walls-only-vs-all-surface scope gap — so we expose both bases rather than average to a false point. Fixr and Homewyse whole-home totals (2–3× higher) are all-surface, high-grade, GC-marked-up figures and are excluded from this walls-only model, cited only for per-item unit costs. Every figure is rounded to the nearest $250 on purpose: a national estimate quoted to the dollar is false precision. The model is reviewed annually; this page was last computed from data updated 2026-07-05. For your own project, the only numbers that beat these are the ones in a written bid from a licensed local painter — get at least three.

Don't forget disposal in the budget

A project this size usually needs a rolloff dumpster, and rental plus overage fees are a real line item. See the right container size and what disposal typically adds to the budget.
