Where engineering decisions get made and defended

Every formula, code provision, and product rule is visible inside the calculation. Decisions get made, checked, and defended where the work happens, not reconstructed later.

Engineering decisions stall at review time

Engineering work moves forward when a calculation can be checked, traced, and reused. That breaks when the basis of design is split across tools and files.

Calculations are isolated

Spreadsheets, legacy tools, and one-off files

Standards are separate

PDFs, folders, and paywalled portals

Product data is elsewhere

Catalogs, submittals, and email threads

The trace is missing

Load cases, combinations, governing checks, and code clauses are not tied to each result

Changes are hard to audit

Logic is spread across cells, hidden tabs, and copied workbooks

Old clauses keep circulating

Standards updates rely on manual spot checks across copied files

See how Calcs.com keeps the basis of design inside every calculation.

Put the basis of design inside the calculation

Calcs.com keeps inputs, formulas, and code references together so reviewers can inspect the logic before they rely on a result.

Load changes propagate automatically

When a load changes upstream, every connected member updates. No manual rechecking downstream.

Inspectable calculations

See every input, formula, and reference during review

Standards applied in context

Code provisions are tied to the checks that use them

Proof teams trust Calcs.com in real work

The load linking feature is huge for us. Before, we had to use separate calculators and manually input everything.

Frequently asked questions

What is Calcs.com?
Calcs.com is a standards-aligned calculation platform for structural engineers, manufacturers, and standards bodies. It embeds formulas, code provisions, and product rules directly into calculations. Design decisions are made, checked, and defended where the work happens. Calcs.com operates across the US, Australia, Canada, New Zealand, and the EU.
What codes and standards does Calcs.com support?
Calcs.com is built to US codes (IBC, AISC, ACI, NDS), Australian and New Zealand standards (AS/NZS), Canadian codes (NBCC), and Eurocode. Each calculation displays the specific code clause applied, so engineers can verify compliance directly in the tool. The calculation library is updated when standards change.
How is Calcs.com different from spreadsheets or legacy calculation software?
Calcs.com makes the basis of design inspectable. Every formula, input, and standards reference is visible before you rely on a result. Reviewers evaluate engineering judgement rather than reconstruct logic from scratch. When a standard is revised, Calcs.com updates. No manual spot-checks across copied files.
Who uses Calcs.com?
Solo structural engineers and small firms use Calcs.com for fast, defensible calculations they can stand behind. Engineering teams use it to keep review standards consistent across projects and offices. Manufacturers use it to get their products specified correctly at the design moment. Kusch Consulting saved 10-20% of project time after adopting Calcs.com. Atlas Tube reached 2,500+ users within 12 months of publishing their first calculator.
Is Calcs.com free to try?
Calcs.com offers a 14-day free trial with no credit card required. The trial includes immediate access to the full calculation library and load linking across real projects.
