How Much Does It Cost to Paint a Room?
DIY costs materials. A professional costs labour. Here is the real breakdown of both.
Painting a room yourself costs $100 to $200 in materials. Hiring a professional costs $300 to $900 for the same room. The gap is almost entirely labour — the paint itself is rarely more than a third of a professional quote.
Estimates only. Textured walls, high ceilings, sprayers and major colour changes can all increase the amount you need. Always buy slightly more than the calculation suggests.
Materials cost by room size
| Room / surface | Surface | Coats | Paint | Paint cost |
|---|---|---|---|---|
| Small room, 10x10 | 284 sq ft | 2 | 2 gal | $70 |
| Standard room, 12x12 | 333 sq ft | 2 | 2 gal | $70 |
| Large room, 12x14 | 365 sq ft | 2 | 3 gal | $105 |
| Master bedroom, 14x16 | 393 sq ft | 2 | 3 gal | $105 |
| Living room, 16x20, 9 ft | 561 sq ft | 2 | 4 gal | $140 |
Paint at $35 per gallon, two coats, plus primer and a $30 supplies allowance. Labour is not included — this is the DIY materials figure.
What you are actually paying for
The materials figure the calculator gives you is real, but it is not the whole DIY cost. Here is where the money goes:
- Paint: the biggest single item, and the one people try to cut. This is a false economy — cheap paint covers worse, so you buy more of it and do more coats.
- Primer: roughly 70 % of the price of topcoat per gallon. Often skipped, and often the reason a job needs three coats instead of two.
- Consumables: roller, sleeves, tray, brushes, tape, drop cloths, sandpaper. $30 to $50 for a first job, much less afterwards because the tools last.
If you already own the tools, your second room costs noticeably less than your first.
When a professional is worth it
Professional painters typically quote $300 to $900 per room, or roughly $2 to $4 per square foot of floor area. That is a wide range because it depends on ceiling height, the condition of the walls, how much furniture has to be moved, and how much patching is needed.
A professional is usually worth the money when:
- The walls need real preparation — patching, sanding, filling cracks. This is the slowest part of the job and the part amateurs do worst.
- The room has high or vaulted ceilings, or a stairwell. Access is the whole problem.
- You are painting a whole house. One room is a weekend; eight rooms is a month of weekends.
- The finish has to be flawless — a dark, high-gloss colour on imperfect walls shows every defect.
Where a professional is not worth it: a standard room, in decent condition, in a light colour, with 8-foot ceilings. That is a job two people can do well in a weekend.
The costs nobody budgets for
- Your time. A 12x12 room takes one person about 8 to 12 hours across two days, including drying between coats. At any reasonable hourly rate, that is the largest cost of the whole project — and the reason "DIY is cheaper" is not always true.
- Prep you did not expect. Every older room has cracks, nail pops or patches that only become visible once the furniture is out.
- Colour mistakes. A colour that looked right on a two-inch swatch can look wrong on four walls. Buy a sample pot and paint a one-foot square on two different walls before committing.
- The second trip. Running out of paint at 80 % completion costs you a drive and possibly a batch mismatch. This is why every calculator on this site rounds up.
Frequently asked questions
How much does it cost to paint a 12x12 room?
About $100 to $150 in materials if you do it yourself, or $300 to $600 for a professional. The paint itself is only about $70 of the DIY figure.
Is it cheaper to paint a room yourself?
In materials, yes — a professional charges three to five times as much. But a 12x12 room takes 8 to 12 hours of your own work, so the real answer depends on what your time is worth.
How much do painters charge per room?
Typically $300 to $900 per room, or roughly $2 to $4 per square foot of floor area. Ceiling height, wall condition and access all push the figure up.
How much paint do I need to budget for?
Use the paint calculator above with your own room dimensions. The materials total it shows is the number to budget — the labour figure depends on whether you are doing it yourself.
