ClearCalcs
Standards-aligned structural calculation platform with 200+ inspectable, code-referenced calculators for beam, column, frame, shear wall, retaining wall, and wind/seismic design.
4.2 /5 composite score
The most solo-friendly structural calc tool -- inspectable code-referenced outputs, load linking that propagates changes automatically, and concurrent-user floating licenses that suit a solo or two-person shop.
Rubric Scorecard
| Criterion | Score | Rationale |
|---|---|---|
| Maturity | 4/5 | 12 million designs completed and 80,000 structural projects in the past 12 months; formerly ClearCalcs, now at calcs.com; 14-day free trial and 30-day money-back guarantee. |
| AEC Specificity | 5/5 | 200+ calculators covering IBC, AISC, NDS, ACI, AS/NZS, NBCC, and Eurocode; every formula and code provision is visible during review -- not a black-box result. |
| Integration | 3/5 | PDF and Excel export for permit packages; load linking propagates member changes across connected elements; no direct BIM import. |
| Value / Pricing | 5/5 | Basic $79/month ($66/mo annual); Pro $119/month; Ultimate $149/month -- all plans are floating concurrent-user licenses, so a solo engineer pays the same as a small team. |
| Evidence | 4/5 | Capterra rating 4.6/5 from 37 verified reviews; G2 listing active; reviewers consistently cite best-in-class customer support and value for a small firm. |
