Estimating framing cost means building up from the measured quantities to a bid price. The build up is: materials + labor + equipment = direct cost, then + overhead = job cost, then + profit = bid price. Each layer has a range, not a fixed number, and your actuals depend on region, square footage, design complexity, and lumber market. Framing is a board foot and lineal foot driven trade, so the takeoff and the lumber package make or break the number.
What You Are Pricing
Framing scope breaks into five buckets you price separately: plates and studs, joists and rafters, sheathing, hardware, and finish and punch. Plates and studs are the wall framing, measured in lineal feet of plate and count of studs. Joists and rafters are the floor and roof framing, measured in lineal feet by span and spacing. Sheathing is the plywood or OSB on walls, floor, and roof, measured in square feet. Hardware is the hangers, straps, holdowns, and clips that tie it together, and on engineered plans it is a real line item. Finish and punch is the blocking, nailers, bracing, and correction work that closes the frame for the next trade.
Unit costs for framing are built up from lumber price, labor hours times wage, equipment, waste, and markup. A square foot of wall is not just the stud: it is the plate, the studs, the headers, the sheathing, the nails, and the labor to assemble and raise it. Price each assembly as a built up unit, or you will underprice the labor, which is the bulk of the cost.
Direct Cost Buildup
Direct cost is what you spend on the job: materials plus labor plus equipment. Materials you pull from your lumber takeoff priced at current market, and lumber prices move week to week, so quote the package close to the bid. Labor you build from the square footage times the production rate times the wage. Equipment on framing is mostly a forklift, a boom lift, and air compressors and nailers, and on small jobs it is often buried in overhead rather than priced direct. Waste on lumber runs 10 to 15%, more on complex cuts, and add a small percentage for broken or bent hardware.
Labor rate means burdened labor, not the wage on the check. A $30 per hour wage becomes $45 to $55 per hour billed once you add payroll taxes, workers comp, insurance, and tool allowance. Production rates vary by assembly: wall framing runs 200 to 400 SF per day per carpenter, floor framing runs 150 to 300 SF, and roof framing runs 100 to 250 SF depending on pitch and complexity.
Step by Step Cost Estimate
For a representative scope, a 2,000 SF two story wood frame house with 9 foot walls and a stick framed roof, walk through the buildup:
- Price wall framing: 3,200 SF of exterior and interior wall at $4 to $7 per SF for plates, studs, headers, and labor. That is $12,800 to $22,400.
- Price floor framing: 2,000 SF of joists and subfloor at $3 to $5 per SF for joists, sheathing, and labor. That is $6,000 to $10,000.
- Price roof framing: 2,400 SF of rafters and sheathing at $5 to $9 per SF for rafters, ridge, sheathing, and labor. That is $12,000 to $21,600.
- Price hardware: hangers, straps, holdowns, and clips at $1,500 to $3,000 as a lump sum from the plan.
- Add finish, waste, and mobilization: blocking and punch plus a 10% waste allowance, $2,000 to $4,000.
Adding the midpoints: direct cost lands near $34,300 to $61,000 depending on lumber market, design, and hardware. Engineered products like I joists and trusses change the split between material and labor but generally land in the same range.
Factors That Move the Number
Design complexity is the biggest cost driver. A simple rectangle with a gable roof is fast. A two story with multiple hips, valleys, dormers, and angled walls means more cuts, slower production, and more waste per square foot. Wall height moves cost: 10 foot walls cost more than 8 foot walls in studs, plates, and labor. Stud spacing matters because 16 inch on center uses more studs than 24 inch, and the difference is real on a large house. Roof pitch matters because a 12:12 pitch is slower to frame and sheath than a 4:12, and steep work means lifts and safety equipment.
Lumber market swings the material price week to week, and a package quoted in January can move 15 to 20% by April, so price the lumber close to the build. Region moves wages and material prices both: a journeyman carpenter runs $30 to $40 per hour in low cost markets and $50 to $70 in high cost markets. Engineered versus stick is a real split: trusses save field labor but cost more up front, and I joists span farther but require careful handling. Hardware for seismic and high wind zones adds hangers, straps, and holdowns that show up on the plan and in the price.
Common Mistakes
- Pricing square feet without a takeoff. A square foot number without the lumber list is a guess, not an estimate.
- Quoting lumber far ahead of the build. Lumber moves, and a stale quote eats your profit.
- Forgetting the hardware. Hangers, straps, and holdowns are on the plan and they add up fast on a big house.
- Ignoring design complexity. A complex house is slower per square foot, and using a simple house rate underprices the job.
- Using markup instead of margin. They are not the same: 10% markup on $10,000 is $11,000, but 10% margin is $11,111.
- Skipping finish and punch. Blocking, nailers, and correction work are real labor and easy to miss.
Putting It Together
Take your direct cost, add overhead, then add profit. Overhead covers the costs of doing business that are not on the job: insurance, office, trucks, shop, mobilization, supervision, and accounting. A general range is 10 to 20% of direct cost, lower for large simple frames, higher for small or complex jobs. Profit is what you keep after all costs. A general range is 5 to 15% of direct plus overhead, lower in competitive markets, higher for custom or complex work.
On the example, direct cost of $47,500 with 15% overhead adds $7,125 for a job cost of $54,625. Ten percent profit on job cost adds $5,463, landing the bid near $60,000. Run the same math with your actual overhead rate from your books and your target profit for the risk. Then check the bid against a sanity check: $60,000 over 2,000 SF is $30 per SF framed, which sits inside the normal range for a two story wood frame house. If your number lands well below that, you probably missed the hardware or the roof labor. If it lands well above, check whether you are pricing custom work on a production plan or double counting the sheathing. The takeoff and the lumber package are where the money is, not the percentages.
