Beam Deflection Calculator

The Simply Supported Beam Calculator computes reactions, shear, bending moments, slopes, and deflections for multiple load cases. It includes options for material modulus and moment of inertia to produce deflection results. Calcresource also provides a separate cantilever beam calculator on the same site for matching beam type coverage.

Buyer's guide

How to choose a beam deflection calculator

When picking a beam deflection calculator, first decide what you need most: quick checks for a simple simply supported beam, or a tool that also handles cantilevers and continuous spans. Then consider whether you want to see stress and shear diagrams, or just deflection numbers. If you prefer no sign-up and a clean interface, Omni Calculator or Calcresource are the easiest paths; if you need professional-grade output and are willing to tolerate limited free use, MechaniCalc or SkyCiv offer more depth.
