How to price a painting job

In this article

Painting is the trade where the quote and the job are furthest apart. Two identical rooms, same size, same paint — one takes a day, the other takes three, because one had nail holes and the other had wallpaper glue, water stains and a customer who chose white over navy.

So the market rates below are a starting point, and everything after them is about the four things that actually move the number: coats, prep, access, and colour change.

What people are actually charging

Job	Range	Notes
Interior, per square foot	$2–$6	About $2.75 walls only; $4.70 with trim and ceilings. That gap is the single most useful number in this article.
Whole interior	$965–$3,089	National average $2,022. The full spread runs $350 to $5,800.
Per room	$300–$1,000	Averages around $624. Bedroom $240–$720, kitchen $300–$960, living room $700–$2,000, bathroom $140–$420.
Painter’s hourly billing	$25–$75	$70–$100+ for specialty work or expensive metros. Do not confuse this with what you pay a painter.
Painter’s wage	about $21.50/hr	What the person holding the brush earns. The gap between this and the line above is your insurance, van, tools and office — not profit.
Paint, per gallon	$13–$35	Flat $13, semi‑gloss $17, high‑gloss and low‑VOC $35, primer $10. Contractor‑grade sits at the top of that.
Coverage	350–400 sq ft	Per gallon, per coat, on a sealed surface. Bare drywall and deep colour changes drink far more.

Price the room, not the square foot

Per‑square‑foot bidding is fast and it is why detailed houses get underpriced. It cannot tell the difference between a plain box bedroom and the same bedroom with four doors, a built‑in closet and picture rail. Estimating is a science, not an art — and the room is a better unit than the wall.

A working ladder for interior repaint, in reasonable condition, at 8 ft ceilings:

Item	Typical	Notes
Bedroom, 10 × 12	$550–$650 all in	Walls $350–$400, trim $100–$125, ceiling $100–$125. Price the three separately — customers drop the ceiling far more often than they drop the walls.
Each door	$50	Both faces and the frame. Four doors is another $200 that a per‑square‑foot bid never sees.
Closet	$50–$150	Depends entirely on whether it is empty and whether it has shelving.
Shelving	$10–$25 a shelf	Slow, fiddly, and always forgotten at the quote.
Ceiling above 8 ft	add for height	A 10‑ft ceiling adds hundreds of square feet of wall across a house, plus staging. This is the most commonly missed cost in the trade.

Build your own version of that ladder from your last twenty jobs and quote from it. Then use the per‑square‑foot number only to check the total.

Measure it properly, or none of the above matters

• Perimeter × ceiling height for wall area, room by room. Not floor area — floor area will underprice you by a third.
• Subtract windows, doors and cabinet runs. A kitchen with three walls of units has far less paintable wall than its size suggests, and a bedroom with a wall of glass has less than you think.
• Add ceilings separately if you are painting them, and price them as their own line.
• Never use the customer’s measurements. They measured the floor, or they measured in 2019.
• Take your most experienced painter to anything unusual. They will spot the failed caulk, the water stain and the wallpaper glue that you will otherwise absorb.
• After the job, compare actual hours against the estimate. This is the only thing that ever makes anyone a better estimator, and almost nobody does it.

Labour is 75–95% of the job. Price that, not the paint.

This is the number that reorganises how you quote. On a residential repaint, labour is 75 to 95% of the total cost. Materials are 15–30%.

Which means: shopping harder for paint is close to pointless, and getting your day estimate wrong by half a day is catastrophic. A painter who saves $80 on materials and under‑estimates by four hours has lost money on the job and feels clever about it.

It also means the honest way to quote is bottom‑up, from days, and then check the answer against a per‑square‑foot rate — never the other way round.

The four things that actually move the number

Factor	What it does	How to price it
Prep	Wash and go, versus filling and sanding, versus stripping and repairs. This is where paint jobs are won and lost.	As a multiplier on your days, not a line item. Heavy prep is not “plus two hours” — it is a different job at 1.5–2× the time.
Coats	A refresh is one coat. Standard is two. A real colour change is three, and no amount of hoping changes that.	Derive the paint from area × coats ÷ coverage. Never guess gallons — that is how you end up doing a third coat out of your own pocket.
Colour change	Dark to light is the expensive direction. Red and deep blue over white can need a tinted primer plus three coats.	Quote it as three coats from the start and say why. Customers accept it before the job and never after.
Access	Stairwells, vaulted ceilings, tall entryways. Same square footage, twice the time, plus staging.	A flat height premium per area, decided before you are standing in the hall doing mental arithmetic.
Texture and porosity	The one nobody prices. Bare drywall, stucco and heavy texture drink paint — stucco can take twice what a smooth surface does.	Add about 20% to the paint on any porous or textured surface, and remember primer covers far less than paint: 200–300 sq ft a gallon against 300–400.

Two more that catch people out. New construction takes about 30% longer than a repaint of the same area, because of the priming and caulking. And interior work takes two to three times the hours of the equivalent exterior square footage — the masking, the detail and the cleanup are the job, not the painting.

The painting quote calculator does exactly this: it derives your paint from area, coats and coverage, then treats prep as a multiplier on days rather than an afterthought, so you can see what heavy prep really costs before you have promised a number.

Building the quote

• Measure the surface, not the floor. Walls plus ceilings if you are doing ceilings. Floor area is a different number and using it will underprice you by a third.
• Estimate crew‑days first. Painters × days. This is the whole quote; everything else is small.
• Apply the prep multiplier before you go any further, not after you have an answer you like.
• Derive the paint. Area × coats ÷ coverage, rounded up to whole gallons, plus 10–15% for waste. Buying four gallons for a job that needs 4.2 is a second trip to the store.
• Add sundries. Tape, filler, sheets, sandpaper, liners, brushes. Budget $30–$50 per average room, or about a quarter of the paint cost, whichever you find easier to remember. Small, constant, always forgotten.
• Add the day rate you actually pay, loaded. A $21.50 wage is nearer $26 an hour once payroll taxes, comp and holiday are on it. If you have no idea, $20 an hour is a safe floor to build from anywhere in the country.
• Recover overhead per billable hour, not per job. Total your monthly overhead — van, insurance, phone, advertising, the evenings quoting — and divide by the billable hours you actually work in a month. $5,000 over 800 hours is $6.25 an hour. Then attach it to the hours the job takes. Splitting overhead evenly across jobs instead overcharges the half‑day touch‑up and undercharges the two‑week whole‑house, which is the wrong way round.
• Add the margin. A small outfit should not go below 30% gross after labour and materials; an established company should be nearer 50%. Aim for at least 20% net after everything — and note that a 20% markup on cost is not a 20% margin on price.
• Check the answer per square foot, and per labour hour. Under $2 a square foot and you have missed something; over $6 and you are quoting a specialty job, so make sure the customer knows that is what they are buying. Then divide your labour by the area — somewhere near $0.80 a square foot is a normal interior repaint.

The quote is the product

Painting is bid work. You are not paid for the quote and you will lose most of them, so the cost of quoting is a real cost of every job you win. At a 30% win rate, three quotes are paid for by every job — and if a quote costs you an evening, that is a working week a month.

• Same day, in writing. The first credible written quote wins a startling share of residential work.
• Itemise what is not included. Furniture moving, filling large holes, ceilings, second colour in the same room. Exclusions prevent more arguments than inclusions do.
• Photograph the walls at the quote. Every dispute about “that damage was there before” is settled by a photo with a timestamp.
• Take a deposit — at the rate your state allows. A third at booking is often quoted as normal and is above the legal cap in several states; California allows 10% or $1,000, whichever is less. Check the rules before you write a number down. A customer unwilling to pay any deposit is still telling you something.
• Never quote a colour change without seeing the current colour. Never.

Sources

Every figure above comes from one of these, checked in August 2026. We publish them because nobody else in this trade does — most painting pricing guides quote numbers with no source at all, which makes them impossible to check.

• HomeAdvisor, cost to paint a home interior — national average and range, per‑square‑foot rates, cost by room and by home size, paint prices and coverage, and the labour share of total cost. Built from homeowner‑reported project costs.
• HomeGuide, interior painting costs — per‑room averages and the walls‑only versus walls‑trim‑and‑ceilings split.
• US Bureau of Labor Statistics and PayScale — what a painter earns, as distinct from what a painter bills.
• Benjamin Moore, estimating paint jobs — measuring paintable area, the ceiling‑height effect, the 30% loading on new construction, and interior taking two to three times the hours of equivalent exterior area.
• The per‑room ladder, the overhead‑per‑billable‑hour method and the margin floors are drawn from how the painting trade’s own estimating guides teach it, cross‑checked across several independent ones. They are rules of thumb rather than survey data and should be treated that way — your last twenty jobs beat all of them.

Ranges move. If you are reading this a long way from 2026, re‑check HomeAdvisor first — it is updated yearly and it is built from what homeowners actually paid rather than from what anybody is selling.
