Good work starts with a reliable number.
Cut & Calc is a growing library of practical calculators for people who build, repair, fabricate, and make.
Why we built it
Project math is rarely difficult in theory. The hard part is finding the right formula, using the right units, and remembering the real-world allowance that keeps a small error from becoming wasted material. Cut & Calc brings those steps together in tools that are quick enough to use at the bench or on the jobsite.
Inputs and results use terms that make sense in the workshop.
We show assumptions, units, and practical notes wherever they matter.
No account is required. Tools are fast, focused, and free to use.
What we cover
Our roadmap spans woodworking, construction, metalworking, home improvement, and general workshop planning—from board feet and kerf to concrete, stairs, sheet layout, weight, and fastener estimates.
A practical safety note
Cut & Calc provides planning estimates, not engineering approval. Always verify measurements, material specifications, tool setup, and local building requirements before cutting, ordering, or constructing.
