Interior and exterior painting have different cost drivers. Based on your 1,800 sqft home.

TypeRange (Basic)Range (Premium)What's Included
Interior$3,600$10,800Walls, ceilings, trim, doors — prep, primer, 2 coats
Exterior$1,890$5,040Siding, trim, shutters, doors — power wash, prime, 2 coats
Interior + Exterior$5,490$15,840Full home repaint — often bundled for discount
Tip: Bundling interior + exterior often saves 10–15% vs. separate projects. Contractors prefer efficiency of doing the full home at once.

Paint finish affects durability, cleanability, and appearance. Use the right sheen for each surface.

How to Use This Painting Cost Calculator

This calculator estimates professional painting costs across three detail levels — from a quick project estimate to finish-by-finish guidance and ROI analysis.

Quick Calculator

Select your project type (interior, exterior, or both), enter your home square footage, and choose your paint quality level. Interior costs are calculated at $2–6/sqft based on quality; exterior costs at $1.50–4/sqft. The calculator shows your estimated professional cost, DIY cost, and gallons of paint needed.

Advanced: Interior vs Exterior, Room-by-Room & DIY

The Interior vs Exterior tab shows full cost ranges at every quality level and what's included. The Room-by-Room tab lets you price each space individually — bedroom $300–750, living room $600–1,200, kitchen $400–800, bathroom $200–500. The DIY Savings tab calculates your actual material cost versus hiring a pro.

Pro: Paint Type Guide, Prep Work & ROI

The Paint Type Guide covers flat through gloss finishes — where to use each, durability, and cost premium. The Prep Work tab flags lead paint risk for pre-1978 homes and itemizes prep costs that are often hidden in quotes. The ROI Analysis shows why fresh paint delivers 100–200% return — the best ROI of any home improvement.

How Painting Costs Are Calculated

Interior Cost = Home Sqft × Cost per Sqft ($2–6 depending on quality)

Exterior Cost = (Home Sqft × 0.35 × Stories) × Cost per Sqft ($1.50–4)

DIY Cost = (Gallons Needed × $30–70/gal) + Supplies ($100–200)

Paint needed = 1 gallon per 350 sqft per coat × 2 coats

Labor accounts for approximately 65% of professional painting cost. Paint and materials make up 20%, and prep work (caulking, priming, patching) accounts for the remaining 15%. Premium paint costs more upfront but lasts 5–10 years versus 3–5 for cheap paint — often a better long-term value.

Example: Interior Paint Job on a 2,000 Sqft Home

The Garcias' Pre-Sale Interior Repaint

A family in Austin, TX repaints their 2,000 sqft, 4-bedroom home before listing. They choose mid-grade paint in neutral greige tones throughout.

Home Size2,000 sqft interior
Paint QualityMid-Grade ($3.50/sqft)
Pro Cost Estimate$7,000
Paint Needed~23 gallons (2 coats)
DIY Paint Cost~$1,265 (23 gal × $55)

DIY Total~$1,415 (saves $5,585)
Estimated ROI150% ($7,000 cost → $10,500 value added)

They hired a pro for $7,000 and the home sold in 8 days at asking price. Their agent confirmed the fresh neutral paint was cited by multiple buyers as a key factor. The $7,000 investment returned an estimated $10,500 in added perceived value.

Frequently Asked Questions

Professional interior painting costs $2–6 per square foot of living area, including labor and materials. A 1,800 sqft home typically costs $3,600–$10,800 depending on paint quality, number of rooms, ceiling height, and condition of existing surfaces.
Exterior painting costs $1.50–4 per square foot of wall area, which is roughly 35% of your home's floor area per story. A 1,800 sqft two-story home typically costs $2,800–$8,000 for a professional exterior paint job including power washing, prep, and two coats.
DIY painting saves 60–70% versus hiring a professional, since labor accounts for about 65% of the total cost. You'll spend $30–70 per gallon on paint plus $100–200 in supplies. The main cost is your time — expect 1 day per room for prep and two coats.
Fresh paint consistently delivers 100–200% ROI — the highest return of any home improvement. A $3,000 paint job can add $4,500–$6,000 in perceived value, and staged homes with fresh neutral paint sell 5–10% faster than unpainted homes.
Yes, if your home was built before 1978, lead paint testing ($250–400) is strongly recommended before any sanding or scraping. The EPA requires contractors to follow lead-safe work practices, which can add 20–40% to the project cost. Home test kits are available for $30–50 but lab testing is more reliable.
