Key Takeaways
- Estimating carpentry cost = quantities × (material + labor) + overhead + profit.
- Use your actual $40-75/hr labor rate, not national averages.
- Reference Carpentry costs: $2.50-6.00/LF/trim carpentry, $200-600/EA/door installed, $5-12/SF/rough carpentry.
- AI takeoff does the quantity step in minutes; pricing stays yours.
Step-by-step: how to estimate Carpentry cost
- 1. Take off quantities. Measure trim and casing lf and other carpentry scope from the plans (AI takeoff reads PDFs in seconds).
- 2. Price materials. Get real quotes for Dimensional lumber, Trim and moldings, Doors and hardware, Cabinetry — not list prices.
- 3. Apply labor. Use your burdened carpentry rate ($40-75/hr (carpenters)).
- 4. Add waste. 5-15% typical for carpentry materials, per your actuals.
- 5. Add overhead and profit. 10-20% overhead, 5-15% profit — from your books.
- 6. Sanity-check. Compare per-unit to the ranges below; investigate any outlier.
Carpentry cost reference
| Item | Typical range | Unit |
|---|---|---|
| Trim carpentry | $2.50-6.00/LF | |
| Door installed | $200-600/EA | |
| Rough carpentry | $5-12/SF |
Worked example
For a mid-size carpentry scope, multiply your quantities by the material and labor rates above, add waste, overhead, and profit, then divide by the relevant unit. Compare the result to the $2.50-6.00/LF range for trim carpentry. If you are far off, find out why before you bid.
Frequently Asked Questions
How do you estimate Carpentry cost?
Take off quantities from the plans, price material and labor per your local rates, add overhead and profit, then compare the per-unit total to the ranges here. AI takeoff speeds the quantity step from hours to minutes.
What labor rate should I use for Carpentry?
Use your actual burdened labor rate for your market — $40-75/hr (carpenters). Burden includes taxes, benefits, and overhead on top of base wages.
How much waste should I add for Carpentry?
Waste factors vary by material and trade — typically 5-15% for carpentry materials. Use your historical actuals; generic factors are a starting point only.
What overhead and profit should Carpentry bids carry?
Overhead commonly runs 10-20% and profit 5-15%, but set both from your own books and the project's risk — not rules of thumb.
How accurate are the Carpentry ranges here?
They are general industry benchmarks for planning. For a defensible number, take off the actual plans and price with your local vendor quotes and labor rates.
