With the figures above, the estimated labor cost comes to 1800 $ (estimated labor cost). Note that estimated hours and crew size sit at the edge of the range this calculator was checked against, so treat the output as indicative rather than settled. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market? Change the selector above so the units and code reference follow.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

[Schema Verified] Computed in alignment with American Concrete Institute (ACI 318-19) formulas and International Residential Code (IRC 2024) spatial boundaries.

Frequently asked questions

Does this include materials cost?
No — this is labor only. Use the Renovation Budget Calculator or Cost Per Square Foot Calculator alongside this one to build a fuller project estimate, or add material line items in the Project Builder.
Should I use my own hours or the total crew-hours?
Enter the hours the job takes per worker (i.e. the job's duration), not the total crew-hours — this calculator multiplies by crew size for you.
How do I account for overtime rates?
Run this calculator twice — once for regular hours at the standard rate, once for overtime hours at the overtime rate — and add the two totals together.
