Structural Engineering Calculation Software
Most of our customers are small firms. Two seats. Ten or fewer engineers.
They use ENERCALC because it handles the structural calculations they do every day, quickly, reliably, and without fighting the software.
Over 6,000 firms use it. Some of them have been using it for over 40 years. We still have our first customer from 1982 and many with over 30 years of active use. The average tenure of our users is 17 years.
Twenty of the top 25 ENR 2026 Design Firms use ENERCALC too, but this software was built for firms like yours.
ENERCALC SEL
ENERCALC SEL is what most people mean when they say “ENERCALC.”
It’s 64 modules covering the component-level work that makes up most of your day: beams, columns, foundations, walls, earth retention, wind, snow, seismic, and more.
One interface. Steel, wood, concrete, masonry. Pick a module, enter your design data, watch it calculate in real time.
ENERCALC for Revit
ENERCALC for Revit puts our structural calculations “inside” your Revit model. No export. No import.
Select an element in Revit, design and analyze it in ENERCALC, and the results stay connected. Change either side, the other updates.
The code updates problem (solved)
Every time the building code changes, we handle it.
Researching, developing, testing, and documenting our changes for IBC 2024 took us nine months. Our users spent zero hours making those changes. You open ENERCALC and the current code is there.
Who uses ENERCALC?
Structural engineers at small firms who do the same component-level design work every day. That’s our core.
But also:
Civil engineers designing earth retention and foundations.
AEC firms where the same project touches steel, wood, concrete, and masonry.
Corporate facility teams at companies you’d recognize from the highway, the runway, and the launchpad.
Government agencies and military branches designing the infrastructure behind energy research, satellite launches, and everything in between.
Manufacturers who need to optimize the structural design of prefabricated buildings, engineered wood products, and concrete systems.
Our users are in all 50 states and 30+ countries.

ENERCALC SEL
Almost moved to tears
I am almost moved to tears at finally finding this program and using it for the first time today. I tried various software last year and today finally found your software and it is absolutely the best I’ve ever experienced. Appreciate the help you give our industry and hope I can continue getting better with the software. Thank you so much for making my life easier!
