How This Paint Calculator Works
Our calculator computes each selected wall area individually (L × H or W × H), subtracts door and window areas, then applies surface and method factors. Divide net area by coverage rate and multiply by coats.
DIY vs. Professional: What Actually Costs More?
The cheapest number on paper isn't always the cheapest number in practice. Here's the honest breakdown for a typical 12x12 room — DIY materials priced at retail, pro quotes as national averages.
| Cost Item | DIY | Hiring a Pro |
|---|---|---|
| Paint & primer | $80 – $250 | $80 – $250 |
| Supplies (tape, drop cloths, rollers, brushes) | $40 – $90 | $0 — usually included |
| Tools you might need to buy (ladder, tray, sandpaper) | $30 – $110 | $0 |
| Labor | $0 (your time) | $300 – $900 |
| Total for a 12x12 room | $150 – $450 | $380 – $1,150 |
| Time commitment | 1–2 full days | Half a day to 1 day |
DIY isn't free — your time is worth something, and a rushed first coat job often needs a do-over. Pros buy paint at trade prices, so their material cost can actually run lower than retail.
Room-by-Room Cost Table (2026 U.S. Averages)
Typical professional ranges from HomeGuide's 2026 national cost data. Where you land inside each range depends on your city, wall condition, and how much trim and ceiling work is included.
Hiring a pro or doing it yourself?
| Room / size | Pro — walls | Pro — walls, trim & ceiling |
|---|---|---|
| 10×10 bedroom | $320 – $1,200 | $640 – $2,400 |
| 10×12 bedroom | $350 – $1,300 | $700 – $2,600 |
| 12×12 bedroom | $380 – $1,400 | $770 – $2,900 |
| 12×16 bedroom | $450 – $1,700 | $900 – $3,400 |
| 15×15 bedroom | $480 – $1,800 | $960 – $3,600 |
| Living room (~320 sq ft) | $600 – $2,000 | $1,100 – $4,200 |
| Kitchen (walls only) | $150 – $250 | — |
| Bathroom (walls only) | $150 – $400 | — |
Where you fall inside each range matters more than the range itself: metro areas (NYC, SF, Boston, LA) sit at or above the top end, smaller towns near the bottom. Always compare 2–3 local quotes before hiring.

Average Painting Costs by Project (2026)
Ballpark ranges for common projects, using current U.S. market rates. Your exact number depends on region, wall condition, and how many coats you actually need.
| Project | DIY | Professional |
|---|---|---|
| 10x10 bedroom (interior) | $100 – $250 | $300 – $700 |
| 12x12 master bedroom | $150 – $350 | $400 – $900 |
| Entire 1,500 sq ft home, interior | $500 – $1,200 | $1,800 – $4,500 |
| Exterior, 2,000 sq ft home | $400 – $1,000 | $2,600 – $5,700 |
| Single accent wall (12x9) | $40 – $90 | $150 – $350 |
Labor rates typically run $20 – $50 per hour, or $1 – $3 per square foot of interior wall space (HomeGuide, 2025). The U.S. BLS median hourly wage for painters is $23.75 (May 2025). [2]
Ranges are national averages and vary by state and city. Coastal and metro areas sit at the high end.
5 Factors That Move Your Estimate the Most
Paint quality and number of coats
Premium paints ($50+ per gallon) cover better and last longer, but they only matter if you apply the right number of coats. Most rooms need two; a color change or a cheap one-coat paint can quietly triple your material bill.
Surface preparation
Cracks, holes, and peeling paint mean patching, sanding, and priming before a single drop of finish paint goes on. Prep work is where surprise costs show up — both in DIY materials and pro labor.
Ceiling height and trim complexity
Taller walls mean more surface area and more ladder time. Crown molding, wainscoting, and detailed trim add hours of cutting-in that pros bill by the hour and DIYers feel in their patience.
Your region's labor rates
A painter in rural Ohio might charge $20/hour while the same job in San Francisco runs $60+. If you're hiring out, local rates swing your total more than any other single factor.
Wall material and texture
Smooth drywall is cheapest to paint. Brick, stucco, and heavily textured walls drink paint — plan on 15–45% more paint for those surfaces (our calculator factors this in when you pick a surface type).
How We Calculate Your Estimate
Data last updated: September 2026 (HomeGuide 2026 + BLS OEWS May 2025).
Paintable area (sq ft) ÷ coverage per gallon (sq ft) × number of coats = gallons needed. Paint cost = gallons × price per gallon. Labor estimate = paintable area × regional rate per sq ft.
Cost ranges are based on typical 2026 U.S. market rates, cross-checked against HomeGuide national cost data (rooms $300–$1,000; labor $20–$50/hr; interior $1–$3/sq ft) [2] and the U.S. Bureau of Labor Statistics OEWS (SOC 47-2141, median wage $23.75/hr, May 2025) [1]. Coverage figures use standard manufacturer ratings (350–400 sq ft per gallon per coat) [2].

Frequently Asked Questions About Painting Costs
How much do professional painters charge per hour?
Most residential painters charge $20 – $50 per hour, or quote by the square foot ($1 – $6). The U.S. Bureau of Labor Statistics median hourly wage for painters was $23.75 (May 2025). Hourly rates run higher in metro areas and for experienced crews. [1][2]
Is it cheaper to paint a room yourself?
Yes, usually — you skip labor, the biggest line item. A 12x12 room costs about $150 – $450 in materials DIY vs. $380 – $1,150 hired out. The trade-off is your time and the risk of a patchy first-timer finish.
How many gallons of paint do I need for a 1,000 sq ft house?
For interior walls only, roughly 5 – 7 gallons for two coats (walls are about 2,400 – 2,800 sq ft of paintable area in a 1,000 sq ft home). Use the calculator above for your exact rooms. [2]
Why is exterior painting so much more expensive?
Exterior jobs need weather-tolerant paint, more prep (power washing, scraping), taller ladders, and often two people for safety. That's why per-sq-ft pro rates for exterior work run higher than interior.
Do painter quotes include the paint?
Not always. Some quotes are labor-only, others include materials. Always ask what's included before comparing quotes — a labor-only bid can look cheaper and end up costing more.
How long does a pro take to paint one room?
A single room is typically a one-day job for a professional crew — prep, cutting in, and two coats. DIY usually stretches to a full weekend.
