Calcs for
Structural checks you can inspect, verify, and stand behind
Calcs.com is a standards-aligned calculation platform built for engineers. Every formula, variable, and standards reference is visible before you rely on the result. Built to US, Australian, Canadian, New Zealand, and Eurocode standards.

Why current approaches fail
Black boxes slow review and increase liability
Many tools show inputs and a final pass/fail. They do not show the full chain from standard provision to formula to governing case. That creates predictable failure modes.
See the logic before you rely on the result
Calcs.com makes the full calculation inspectable. Every formula, variable, and referenced standards clause is visible before you rely on the result, so engineers can verify the result before they rely on it, and explain it if challenged.
Identify the governing case
Calcs.com shows what governs and why, instead of leaving you to infer it from outputs. Review faster and explain decisions clearly.
Reduce repeat checking
The logic is visible, so you do not need a second tool just to validate the first. Stop running the same calc twice.
Share work that stands up in review
Export a report that includes the inputs, results, and supporting references. Reviewers can follow the calculation without a walkthrough.
Start small, then expand
- [ 01 ]
Start with your weekly checks
Run the calculations you do every week - beams, columns, footings. Familiar work builds confidence fast.
- [ 02 ]
Run alongside your current tool
Use Calcs.com on a couple of jobs while keeping your existing workflow as a reference. Trust the result before relying on it alone.

Link the load path
Connect inputs so changes flow through automatically. A load update no longer means manual rechecking across every member.

Long cantilever LSL roof rafters run deeper at the center span and notch down at the ends. The 22 foot stud walls were framed in LVL.

Rafters, joists, beams and columns were sized in Calcs.com. Modeling and the steel shop detailing both stayed in SketchUp.

Two and a half stories on masonry piers, under strict municipal architectural requirements. Floor joists, ceiling joists and wood beams were all sized in Calcs.com.

The gable of the new cover, closer in. Exposed steel needs the finish held to the same standard as the architecture, so the connections were detailed to be seen.

The stem wall steps down the fall of the land, following the slope rather than cutting it flat.

A 1966 house at the edge of the East Verde River. The March 2023 flood destroyed two of its four stone-clad columns and the county condemned the building.

Losing two columns put the 48 foot sunroom into torsion. Rebuilding them meant new foundations inside the FEMA floodway, so slender exposed steel carries it instead.

Trust & quality
Built and checked by engineers, supported by engineers
Clear enough to verify
See the inputs, what is being checked, and what governs, so you can review the logic and sign off on the result.
Supports multiple codes and materials
Switch standards when you need to, especially when materials or suppliers push you into different codes.
Built and checked by engineers
Calculations are built and tested against real examples so you can trust the output in real projects.
Support from people who do the work
When you have a question, you can get help from engineers who understand the context, not a generic support queue.
Frequently asked questions
Start with a check you already run every week
Pick a calculation type you run every week. Run it in Calcs.com. See the formula, the governing case, and the standards reference before you rely on the result.
