Calcs.com is a structural engineering calculation SaaS from Kooi LLC, positioned as a platform where “engineering decisions can be made, checked, and defended.” It brings inputs, formulas, code provisions, product rules, and calculation results into the same calculation environment, serving structural engineers, engineering teams, manufacturers, and standards bodies. Public information states that it has completed 12 million designs, covered 80,000 structural engineering projects in the past 12 months, and serves markets including the United States, Australia, Canada, New Zealand, and the European Union.
The platform’s core value is not just producing results, but making the basis of calculations reviewable. It offers 200+ standards-aligned calculators covering IBC, AISC, ACI, NDS, AS/NZS, NBCC, Eurocode, and more. Each calculation can show the inputs, formulas, and specific code provisions used, making it easier for reviewers to verify the logic. Load linking is a high-value feature: when upstream loads change, related members update automatically, reducing manual copying of reactions, re-entry, and missed edits. Case materials also mention project defaults, member schedules, folder organization, structural reports/PDF export, and embedding manufacturer product databases into calculations.
The official website clearly offers a 14-day free trial with no credit card required. The trial includes the full calculation library and load linking in real projects. Paid plans come with a 30-day money-back guarantee, but the public pages do not disclose exact pricing, plan tiers, seat limits, or enterprise terms. As a result, value for money can only be judged based on functional benefits rather than actual quoted prices.
The main advantages are transparent calculations and code references shown alongside results, making it suitable for permitting submissions, peer review, and team standardization. Automatic load transfer can significantly reduce rework caused by design changes, with customer cases reporting 10%-30% savings in calculation time. Report export also helps with submissions to building departments or clients. Limitations include insufficient public information on enterprise IT concerns such as permissions, SSO, audit logs, data security certifications, APIs, and third-party integrations. The product is also clearly focused on structural engineering, so it is not suitable as a general-purpose tool for broad engineering calculations or non-structural disciplines.
Calcs.com is suitable for independent structural engineers, small firms, multi-office engineering teams, and manufacturers that want to bring product selection checks earlier into the design process. For teams still relying on Excel, traditional single-purpose calculators, or tools like Enercalc, the main migration value comes from load linking and traceable reports. Access from mainland China, supported payment methods, and local code support are not disclosed, so access status should be considered unknown. If a team must use Chinese domestic codes, pay in RMB, or deploy locally, it may need to evaluate local structural design software or self-built Excel/Mathcad workflows as alternatives.
