Interior Painting Cost 2026: DIY vs. Contractor Pricing

Interior Painting Costs 2026

Painter labor rate: $25–60/hour; most charge $2–6/sq ft of wall surface
Single room (12×12): $350–800 labor + materials
Full house interior (1,500 sq ft home): $3,000–8,000 professional
DIY full house interior: $500–1,500 in materials only

Paint Cost by Type

Budget paint (Behr, Glidden): $25–35/gallon
Mid-range (Sherwin-Williams Cashmere, Benjamin Moore Regal): $45–65/gallon
Premium (Benjamin Moore Aura, SW Emerald): $70–90/gallon

Premium paints genuinely cover better (often one-coat coverage vs. two for budget paints), making total material cost difference smaller than the per-gallon premium suggests.

What Painters Include (and Don't)

Most professional painting quotes include: labor, paint, tape, and drop cloths. They typically exclude: wall repair/patching (add $1–3/sq ft for plaster repair), primer coat (add 20–30% if needed), moving furniture (ask if included), and painting ceilings or trim (often quoted separately).

DIY Realism Check

DIY painting saves 60–70% of cost but requires 2–3 weekends for an average room (prep, painting, second coat, trim). Quality depends heavily on prep work — patching, sanding, and taping properly. Most "bad" DIY paint jobs result from poor prep, not poor application.

Frequently Asked Questions

How many gallons of paint do I need for a room?

One gallon covers roughly 350–400 sq ft of wall surface with one coat. Measure total wall area (perimeter × height), subtract doors and windows, then divide by 350 and multiply by the number of coats (typically 2). Add 10% for waste.

Should I use flat, eggshell, or semi-gloss?

Flat/matte: best for ceilings and low-traffic areas (hides imperfections, hard to clean). Eggshell/satin: best for living rooms, bedrooms, hallways — some sheen, washable. Semi-gloss: best for kitchens, bathrooms, trim — very washable, moisture-resistant. Gloss: trim and doors only — highest durability.
