A drywall bid has two halves that get estimated very differently: the board and supplies, which come straight off the square footage, and the labor, which splits into hanging and finishing. Treat them as one number and you will misprice both. Here is how to estimate a drywall job from takeoff to a bid that holds.
Take off the board area
Start with the total surface to be covered, walls plus ceilings, in square feet. Add waste, because boards get cut around openings, ends get trimmed, and a few sheets get damaged; ten percent is a reasonable starting factor for a normal job, more for cut-up rooms with lots of openings and corners.
Then convert area into sheets at your sheet size. A 4-by-8 sheet covers 32 square feet; a 4-by-12 covers 48. Bigger sheets mean fewer butt joints and less finishing, which is why production crews lean on them where they fit. Divide your waste-adjusted area by the sheet coverage and round up to whole sheets, because you cannot buy a partial board.
Let the supplies follow the area
The consumables scale predictably off board area and sheet count, so once you have those, the rest fills in. Screws run roughly a pound per couple of sheets. Joint compound runs about a box per 450 square feet of board. Tape runs roughly a roll per 1,500 square feet. Corner bead is counted off the actual outside corners. None of these are big lines on their own, but left out of the estimate they come straight out of your margin.
Price all of it against your real supplier costs, and add sales tax on the materials if your market charges it.
Estimate hanging and finishing separately
This is the step that separates a real drywall estimate from a guess. Hanging and finishing are different work at different speeds. Hanging board might run 150 square feet per hour for a solid crew; taping and finishing to a smooth, paint-ready level 4 runs slower, often around 100 square feet per hour, and a level 5 finish slower still. Estimate each with its own production rate, total the hours, and multiply by your burdened labor rate, the wage plus payroll taxes, insurance, and overhead on the labor.
Finish level matters to the price. A garage at level 2 and a great room at level 5 are not the same bid even at the same square footage, and quoting them the same way costs you on the high-finish jobs.
Add overhead and markup before you send it
Board plus supplies plus labor is your direct cost. Your overhead, the truck, the tools, the insurance, the bidding time, has to be carried by the work, so add it, then your markup, and check the margin on the final price. Markup on cost and margin on price are different numbers; confusing them is a quiet way to underbid.
Make it a template, not a one-off
The drywall contractors who bid fast keep their production rates and unit prices saved and just enter the area. The Drywall Estimate & Takeoff Template does it for you, board area with waste rounded up to sheets, screws, mud, and tape auto-filled from the area, hanging and finishing priced separately, and a bid price with the margin shown, plus a price book for hang, finish levels, texture, and patching at your rates.
If you run more than drywall, the Contractor Estimating & Job-Profit System carries the same logic across trades and prints a client-ready proposal. Both are in the Contractor & Trades tools.
Take off the board, let the supplies follow, price hanging and finishing as the separate jobs they are, and never skip overhead and markup. That is a drywall bid that pays.
