How Much to Charge for Drywall: Build the Number From Cost

Short answer: How much to charge for drywall is built, not looked up. Convert wall and ceiling area into sheets — a 4x8 covers 32 square feet, a 4x12 covers 48 — add 10 to 15 percent waste, then price the finish level, because Level 4 versus Level 5 is the largest single variable on the page. Estimate hours by phase, multiply by your burdened crew cost, add overhead per billable hour, then divide by one minus your target margin.

A published per-square-foot number is somebody else’s wage rate, somebody else’s insurance, and somebody else’s ceiling height. What travels is the sequence. Below is one basement finish carried all the way from a tape measure to a number you could defend to a general contractor, with every step you would have to redo with your own costs. The same quantities become the invoice after the job sells.

What am I actually selling — hang, finish, or both?

Decide this before anything else, because the same square footage carries three different prices depending on the answer, and half the “your bid is high” conversations are a hang-only number being compared to a hang-and-finish number.

Scope	What is in it	What is not
Hang only	Stock, cut, lift, fasten, cut openings	Tape, mud, bead, sanding
Finish only	Tape, coats to a stated level, bead set, sand	Board, screws, lifting
Hang and finish	Both, one crew, one schedule	Paint, prime, framing corrections
Board supplied by you	Everything above plus the material takeoff and delivery	Nothing, and price the risk accordingly

Write the answer on the estimate in one sentence. A general contractor comparing four bids will otherwise assume the cheapest scope applies to yours.

How many sheets is the job?

The job below is a basement finish: 1,150 square feet of floor, eight-foot ceilings, one bedroom, one three-quarter bath, a mechanical room, a stairwell, and a soffit boxing the main beam and the ductwork.

Surface	Measurement	Board area
Perimeter walls against foundation framing, single sided	196 lf × 8 ft	1,568 sq ft
Interior partitions, both faces	74 lf × 8 ft × 2	1,184 sq ft
Ceiling, including 5/8 Type X over the mechanical room	1,150 sq ft	1,150 sq ft
Board to be covered		3,902 sq ft
Waste at 12 percent — stairwell, soffit returns, window wells		468 sq ft
Board to purchase		4,370 sq ft

Then choose sheet length, because that is a pricing decision and not just a stocking one. All 4x8 sheets means 137 of them and a butt joint every eight feet. All 4x12 means 92 sheets and far fewer butt joints, which is finishing labor you never have to pay for. A realistic mix here is 78 sheets of 4x12 for the long walls and ceiling plus 20 sheets of 4x8 for the stairwell, the bath, and the soffit — 98 sheets and 4,384 square feet.

Butt joints are the reason this matters. A tapered seam takes compound in a factory-made recess. A butt joint has no recess, so it gets floated wide, feathered, and sanded, and it is the joint that telegraphs through paint two winters later.

What does the material list come to once the sheet count is set?

Price materials from quantities, never as a percentage of labor. Two of these lines do not scale with square footage at all.

Item	How to get the quantity	This job
Board	Purchase area ÷ sheet coverage	78 × 4x12, 20 × 4x8
Screws	~32 per 4x8 equivalent on walls at 16 in o.c. framing; 40 to 48 on ceilings, where field spacing tightens to about 12 in	≈ 4,340 screws
Paper tape	Tapered seams + butt joints + inside corners; typically 300 to 400 lf per 1,000 sq ft of board on residential layouts	≈ 1,365 lf, 3 rolls
Joint compound	Roughly 11 gallons per 1,000 sq ft of board for a three-coat Level 4	≈ 43 gal, 10 boxes of 4.5 gal
Corner bead	Linear feet of outside corner, not square feet	148 lf including the beam soffit
Dust control	Poly, tape, zipper door, HEPA filters and bags	Per job
Scrap disposal	Volume of offcut and sanding waste	Per job

Corner bead is where two jobs with identical board footage diverge. This basement has nine outside corners at eight feet plus a soffit that adds another 44 linear feet — the same 3,900 square feet in an open, square room would carry a fraction of that.

Compound is the other one, and it scales with coat count rather than area, which is why the next section costs more than it looks like it should.

What does Level 5 add that Level 4 does not?

Level 4 is the standard for flat paint: three coats over joints, corners, and fasteners, sanded smooth, with the paper face of the board left bare between seams. Level 5 takes that finished surface and skims a thin coat of compound over every square foot of it, then sands that. Those levels are defined in the Gypsum Association’s GA-214 standard, and they are the language architects and general contractors write specs in.

The upgrade is not a percentage. It is an extra full pass over the entire job.

What changes	Level 4	Level 5 on this basement
Passes over the field of the board	None	One full skim over 3,902 sq ft
Extra compound	—	Roughly another coat’s worth
Extra crew hours	—	About 26 hours to skim plus 10 to sand
Extra dust control	Standard	More sanding, more containment, more filter changes
Total hour increase	Baseline	Roughly 23 percent on this job

Two questions decide it, and you should ask both before quoting anything: what sheen is the paint, and is there a window or a fixture throwing raking light down a long wall. Gloss, semi-gloss, deep colors, or critical lighting mean Level 5. Flat paint on eight-foot walls with normal lighting does not.

Quoting Level 5 hours and delivering Level 4 loses the job to a callback. Quoting Level 4 hours and being held to Level 5 loses the money.

How many crew hours is each phase?

Break the job into the phases you actually schedule, then price each one. These are person-hours for the basement above at Level 4 — use them as a shape and replace every figure with your own logged times.

Phase	Basis	Hours
Stock and stage 98 sheets down an exterior stairwell	Flat, plus the stair penalty	7
Hang walls and ceiling, 3,902 sq ft, panel lift for the 5/8	≈ 70 sq ft per person-hour	55
Cut openings — 14 boxes, 2 doors, 3 window wells, registers	Per opening	6
Set corner bead, 148 lf including the soffit	Per linear foot	7
Tape and first coat	≈ 130 sq ft per hour	30
Second coat	≈ 250 sq ft per hour	16
Third coat	≈ 300 sq ft per hour	13
Sand, vacuum-assisted, plus containment at the stair	≈ 200 sq ft per hour	20
Cleanup, scrap out, punch	Flat	6
Total		160 person-hours

That is about 24 square feet of board per person-hour across the whole job, which sounds slow until you remember it includes carrying every sheet down a stairwell and three separate return trips for dry time. Return trips are the hours a single square-foot rate hides most effectively — a three-coat schedule means the crew comes back twice, and fuel, drive time, and lost scheduling flexibility are all real.

Sanding is also regulated work, not free work. Dry-sanding a whole basement of joints is exactly the exposure behind OSHA’s respirable crystalline silica standard for construction, and vacuum sanding, containment, and filter changes are hours somebody pays for.

What does an hour of crew time really cost, and what does overhead add?

Not the wage. The wage is roughly two-thirds of it.

Component	Per worked hour
Base wage	$27.00
Employer payroll taxes	$2.70
Workers’ compensation — drywall classifications vary enormously by state	$4.60
General liability, vehicle, and consumable tooling: blades, knives, sanding screens, stilts, banjo, lift rental, HEPA filters	$2.90
Paid time off, training, unbillable shop and travel time	$5.30
Burdened cost per worked hour	$42.50

Overhead is a second layer and it is charged per billable hour, not per job. Add the truck payment, fuel, insurance, phone, licensing, advertising, storage, the accountant, and the hours you spend bidding work you do not win. If that totals $28,000 a year and you honestly bill 1,650 hours — not 2,000, because driving, stocking, and quoting are not billable — that is roughly $17 an hour before a single sheet moves.

So each person-hour on this basement costs $59.50 before profit.

Markup or margin — which one am I adding?

These are different numbers and the confusion is expensive. Markup is a percentage of your cost. Margin is a percentage of the price you charge. To hit a target margin you divide, you do not multiply.

Job cost on this basement comes to $11,836 (built in the next section). Here is what the two operations produce:

Target margin	Divide cost by	Price	If you multiply instead	Money left on the table
15%	0.85	$13,925	$13,611	$314
20%	0.80	$14,795	$14,203	$592
25%	0.75	$15,781	$14,795	$986
30%	0.70	$16,909	$15,387	$1,522

A thousand dollars on one basement, repeated across a year of basements. And margin is not take-home either — income tax and self-employment tax come out of it afterward, which is the arithmetic in how much to set aside for 1099 taxes.

What is the whole number on this basement?

Every rate below is a placeholder from one supplier and one crew. Substitute yours line by line.

Line	Math	Amount
Board — 78 sheets 4x12 half-inch	78 × $17.40	$1,357.20
Board — 20 sheets 4x8, 5/8 Type X where required	20 × $15.80	$316.00
Screws, 2 boxes		$64.00
Paper tape, 3 rolls of 500 ft	3 × $8.50	$25.50
All-purpose compound, 10 boxes of 4.5 gal	10 × $19.50	$195.00
Corner bead, 15 sticks of 10 ft	15 × $6.20	$93.00
Dust control — poly, zipper door, HEPA bags		$85.00
Scrap disposal		$180.00
Material subtotal		$2,315.70
Labor	160 hr × $42.50	$6,800.00
Overhead	160 hr × $17.00	$2,720.00
Total cost		$11,835.70
Price at a 25% margin	÷ 0.75	$15,781

Three checks on that number. Material is 14.7 percent of the price, which is normal for hang and finish. Price per person-hour sold is $98.60. And price per square foot of board is $4.05.

That last figure is at or above what most published ranges suggest, and it should be interrogated rather than accepted. The reasons are visible in the takeoff: 98 sheets carried down a stairwell, a 5/8 ceiling, 148 linear feet of bead on a cut-up plan, and containment because someone lives upstairs. The same crew hanging 4x12s on an open new-construction floor with four outside corners would finish in far fewer hours, and the per-foot number would fall with them. That is the whole reason a single per-square-foot price is a poor way to quote.

What do published drywall prices actually tell me?

One thing, and one thing only: that your build-up is off by a factor of two. Aggregated per-square-foot ranges are averages of homeowner-reported jobs across every region, every finish level, and every scope definition, gathered in different years. Regional wages, workers’ comp rates, sheet cost, ceiling height, and how far you drive move the real answer further than any of those averages admit.

These checks are worth more:

Check	Where it usually lands on hang and finish
Material as a share of price	12 to 20 percent — above 25 means the hours were undercounted
Price divided by person-hours	Compare it to burdened cost plus overhead; a thin gap means no margin
Outside-corner linear feet per 1,000 sq ft of board	The single best complexity signal you have
Ceiling area as a share of total board	Overhead work is slower at every phase
Your own last five jobs	Better data than any national figure

How do I find out afterward whether the price held?

By comparing the job you priced to the job you actually paid for, which requires the supply-house tickets and the crew hours to survive the month. Most contractors discover they underbid a basement at tax time, from a bag of curled receipts, eleven months too late to fix the next bid.

Keel is an iOS app that runs entirely on the device — no account, no bank connection, no cloud, no login, and an App Store privacy label that reads Data Not Collected. It does not do the takeoff. What it does is close the loop: the ticket for ten boxes of compound and 98 sheets gets photographed at the counter and read on device by Apple Intelligence, so the $2,315 you estimated is measured against the $2,315 you spent. Runs to the supply house and back are logged as mileage, which is both a genuine cost per hour and one of the plainer self-employed tax deductions. When the last coat is sanded, the invoice goes out from the job with your logo, your numbering, your brand color, and a payment link as a QR code. The ledger is append-only and hash-chained, so what you recorded on the day cannot quietly change later. At year end it exports as one file, or as the Accountant Pack: a CSV plus a one-page summary PDF. Free is $0 with unlimited invoices, receipts, and mileage; Keel Pro is a one-time $249.99 Lifetime purchase, not a subscription.

Frequently asked questions

How do drywall contractors calculate their price?

By converting wall and ceiling area into sheets, adding 10 to 15 percent waste, pricing the material from quantities, estimating crew hours phase by phase, multiplying those hours by burdened labor cost, adding overhead per billable hour, and then dividing the total by one minus the target margin. The finish level and the ceiling share of the board are the two largest variables in that chain.

Should I charge separately for hanging and finishing drywall?

Price them separately internally even when you present one combined number, because they are separate operations with separate crews, rates, and risk. State clearly on the estimate which scope your price covers. Most disputes about a “high” drywall bid turn out to be a hang-only competitor number being compared against a hang-and-finish quote with materials included.

How much more should I charge for a Level 5 finish?

Price it as the extra pass it actually is, not as a flat percentage. A Level 5 skim covers every square foot of board with an additional thin coat plus sanding and dust control. On a 3,900 square foot basement that added roughly 36 person-hours and another coat’s worth of compound, about a 23 percent increase in hours. Calculate it from your own skim production rate.

How many screws and how much mud does a drywall job need?

Plan about 32 screws per 4x8 equivalent on walls at 16-inch framing and 40 to 48 on ceilings, where field spacing tightens. For compound, roughly 11 gallons per 1,000 square feet of board covers a three-coat Level 4. Tape typically runs 300 to 400 linear feet per 1,000 square feet on residential layouts. Verify all three against your own last three jobs.

Why do drywall ceilings cost more than walls?

Every phase is slower overhead. Sheets have to be lifted and held or set with a panel lift, fastener spacing tightens, 5/8-inch Type X is heavier than half-inch and common on ceilings, and coating and sanding above your head is harder and messier than at chest height. Texture and masking usually land on ceilings too. Carry a separate ceiling rate derived from your own timesheets.

What is a fair profit margin on drywall work?

There is no universal figure, and the honest answer is that the margin has to survive your own overhead and your tax bill. What matters more is doing the arithmetic correctly: divide your total cost by one minus the target margin instead of multiplying by one plus a markup. On a $11,836 job, that mistake is the difference between $15,781 and $14,795.
