Interior Painting Cost Estimator

These are 2026 US national averages for two coats over prepared surfaces. Published here so the estimate can be checked rather than trusted, and so you can sanity-test a real quote against them.

The spread within each row is real. It reflects local labour markets, access, ceiling height, how much furniture has to be moved, and how many colours are involved — a room with four accent walls takes far longer than a room in one colour.

If a quote comes in far higher than you expected, trim is usually why. Baseboard, casing, crown and any built-ins are brush work: slow, detailed, and impossible to speed up with a roller. A room with elaborate trim can cost more to paint than a room twice its size without it.

It is also the most common place for scope to be silently different between quotes. “Painting the rooms” means walls to one painter and everything to another. Ask explicitly.

If the budget is tight, trim is also the most sensible thing to defer — freshly painted walls against reasonable existing trim looks perfectly good, whereas fresh trim against tired walls looks unfinished.

Prep is invisible in the finished result and it is the majority of the skill. Filling, sanding, caulking the gap where trim meets wall, spot-priming repairs — a painter who does all of it produces a wall that looks flat under raking light, and one who doesn't produces a wall that shows every old nail hole the first time the afternoon sun hits it.

This is genuinely hard to compare between quotes because nobody itemises it. The useful question is direct: “What's included in prep?” A painter who says “fill, sand, caulk the trim gaps, spot-prime the repairs” is quoting a different job from one who says “we'll fill anything obvious.”

Major repair — skim-coating, texture matching, large patches — is drywall finishing rather than painting, and it is much harder to do invisibly than it looks. If your walls need that, consider hiring the repair even if you paint yourself.

Painting is the highest labour-share trade in the house, at roughly 80%. That makes it the single best value DIY job available — the materials are a small fraction of the total, and the skill needed for walls in a normal room is modest.

It makes less sense as the ceiling height rises, as the trim gets more elaborate, and as the prep gets more serious. High ceilings mean staging and real risk. Elaborate trim means days of brush work. Extensive repair means a skill that takes practice to do invisibly.

The honest self-assessment: walls in a standard-height room, yes. Ceilings, if you don't mind the neck. Trim, if you're patient. Stairwells and two-storey entries, no — that's a scaffolding job.

Exclusions are where a low quote turns into a higher invoice, and they are rarely written down. These are the ones that come up most.

Moving furniture is often the homeowner's job. Some crews will shift a sofa; almost none will empty a room, take down shelving, or handle anything heavy or fragile. Clear the room yourself and the crew starts on time.

Wallpaper removal is separate work and is priced separately, because it is unpredictable — paper that comes off in sheets takes an hour a room and paper that comes off in postage stamps takes a day. Nobody can quote it accurately without testing a corner first.

Lead-safe work practices in a home built before 1978 are a legal requirement in the US for contractors disturbing painted surfaces for compensation, and they add real cost: containment, HEPA vacuuming, specific cleanup verification. A quote that is materially lower than the others on a pre-1978 house is worth asking about directly.

Repair beyond filling — skim-coating, texture matching, replacing damaged trim, fixing water-stained ceilings — is drywall or carpentry work rather than painting. So is caulking exterior gaps, cutting in around flooring that has not been installed yet, and painting inside cabinets or closets, all of which are commonly assumed and rarely quoted.

Finally, the paint grade. “Contractor grade” spans a very wide range, and coverage varies enough between the bottom and the middle of it that the cheaper paint sometimes needs a third coat. Agree the product line in writing, not the adjective.

Regional variation in painting is larger than in most trades, because the cost is overwhelmingly labour and labour prices are local. The same three-bedroom interior can differ by a factor of two between a low-cost metro and a high-cost coastal one, with identical materials.

Three things drive it. Prevailing wage for skilled trades is the largest single factor. Business overhead — insurance, licensing, vehicle and fuel costs, workers' compensation rates — varies substantially by state. And local demand cycles matter more than people expect: a painter with a six-week backlog quotes differently from one with a gap next week, and in most markets that backlog is seasonal.

The practical consequences are worth acting on. Get three quotes rather than two, because the spread tells you more than any single number. Ask for the quote to itemise labour hours and rate rather than a lump sum, which makes comparison possible. And if the timing is flexible, ask when their quiet period is — interior work in particular is often cheaper in the months when exterior work is impossible.

The regional adjustment in this estimator scales the national labour table up or down by price level. It gets you into the right range for planning. It is not a substitute for a local quote, and it cannot know that the one painter in your area with a good reputation is booked until spring.
