How much to charge to paint a room

A homeowner calls: "How much to paint a bedroom?" And you feel the pull to just say a number — $300, $400, whatever came out of your mouth the last time someone asked. Small job, small price, how wrong can you be?

Pretty wrong, it turns out. I run a painting company in the Twin Cities, and single rooms are the jobs I see painters misprice most — not because the math is hard, but because a room feels too small to deserve real math. So the price comes off the gut, the gut anchors low, and the painter spends a day working for less than their helper makes.

Here's how I actually build a room price, with the numbers visible.

Build the number from the job, not the vibe

The method is the same one I use on a whole house — estimate hours honestly, cost them at your real rate, add materials and overhead, then add margin. A room just makes each step small enough to see clearly.

Step 1 — Count the real hours

Take a standard bedroom: 12×14 feet, 9-foot ceilings, walls only, two coats, one window, one door, a closet you're not painting inside of. Here's where the time actually goes:

Move/cover furniture, mask, tape, drop   1.5 hrs
Patch nail holes, spot-prime, sand       1.0 hr
Cut in + roll, first coat                2.5 hrs
Cut in + roll, second coat               2.0 hrs
Touch-ups, pull tape, clean up, reset    1.0 hr
────────────────────────────────────────────────
                                         8.0 hrs

Notice what that says: only about half the day is a brush or roller touching the wall. The rest is setup, prep, and teardown — and that's the honest version, in an occupied home, working carefully. A painter who pictures "a bedroom takes four hours" is picturing the rolling and forgetting everything around it.

Step 2 — Cost those hours at the loaded rate

Not the wage — the loaded rate. Wage plus payroll taxes, insurance, workers' comp, the truck, the downtime. For most painting businesses that burden adds 15–25% on top of the base wage. I use $45/hour as a round loaded number for a decent painter in my market.

8 hours × $45 = $360 true labor cost.

Step 3 — Materials

A room this size takes about a gallon and a half of decent wall paint, plus tape, plastic, patch, a roller cover.

Paint ~$70, sundries ~$25 → $95.

Step 4 — Overhead share

Your insurance, phone, software, marketing, and vehicle don't bill customers — jobs have to carry them. If your overhead runs, say, $9,000 a year across roughly 1,500 billable hours, every hour needs to carry about $6 of it.

8 hours × $6 = $48.

Step 5 — Add margin and quote

Labor (loaded)        $360
Materials             $ 95
Overhead share        $ 48
──────────────────────────
Job cost              $503

÷ (1 − 30% margin)  → $718
──────────────────────────
Quote                ~$700–750

That's a walls-only bedroom at a healthy 30% margin: around $700. Ceiling adds roughly $150–250; painting the trim and door adds more again. In the Twin Cities I see real-world room prices run anywhere from $400 to $900+ for walls, wider with ceiling and trim — the low end is usually somebody pricing from the gut, not somebody faster than physics.

If your gut just said "nobody pays $700 for a bedroom" — some customers won't, and that's fine. The math is telling you what the job costs you. Quoting $350 doesn't change the cost; it just decides who eats the difference.

The room trap: setup doesn't shrink

Here's why small jobs specifically bleed money, and it's worth naming because every surface has its own trap (exteriors have weather and prep blowout; cabinets have process risk).

Rooms have fixed time that doesn't scale down with the room. Loading the truck, driving there, saying hello, covering furniture, masking, washing out, the walkthrough — that's two to three hours that exist whether the room is a powder bath or a great room. On a whole-interior job those hours spread across a week of billable work. On a one-room job they are a third of the job — and gut pricing never includes them, because the gut prices the rolling.

The second trap is the doorway upsell: "while you're here, could you just do the hallway?" Say yes at no charge and you've donated hours on a job that had maybe $200 of profit in it to begin with. Price the add-on on the spot, every time — it's outside what was quoted, and a clear bid is what makes that conversation easy.

What to say on the phone

You can't inspect a room over the phone, so don't quote one — give a range with a floor. Something like: "Walls only, two coats, most bedrooms land between $550 and $850 depending on size, ceiling height, and condition. I can give you a firm number after a ten-minute look." That sentence does three jobs at once. It anchors the customer to a real range instead of the $200 their neighbor's kid charged. It filters out the callers who were never going to pay a professional rate — cheerfully, before you've burned an evening driving out there. And it protects you from the classic phone-quote ambush: the "standard bedroom" that turns out to have 12-foot ceilings, wallpaper glue under the paint, and a water stain nobody mentioned.

If they push for a number anyway, quote the top of the range. It's much easier to come down after the walkthrough than up.

Check the price against reality — once

Whatever you charge for your next room, do one thing after: write down the hours it actually took and run the real numbers against the quote. That's a five-minute profit autopsy, and on small jobs it's brutally clarifying — you'll either confirm your room price works or find out you've been selling Saturdays for $12 an hour. The “Did I make money?” calculator does the math for you, burden and all, free.

In my experience the first room a painter actually measures is the one that fixes their room pricing forever. Not because the math changed — because they finally saw it.

The short version

Count all the hours — setup, prep, and cleanup are half a room job.
Cost labor loaded (wage + 15–25%), not at the bare wage.
Add materials and an overhead share, then a real margin — 30% isn't greedy, it's a business.
A standard walls-only bedroom priced this way lands around $600–800 in most metro markets; sanity-check your own numbers, not mine.
Never absorb the "while you're here" — price it.
