For engineers and construction professionals who want to guarantee the security and stability of their projects, beam calculators are crucial instruments. The load capacity, deflection, and bending moment are just a few of the many beam design calculations that can be aided by using a free beam calculator. Online, a large range of beam calculators, both paid and unpaid, are accessible. 

A structural beam’s stress and deflection under a specific load are measured using a beam calculation. The qualities of the beam, the load, and the supports are just a few of the variables that affect a beam’s ability to withstand bending.

An excellent tool for quickly verifying beam forces is the beam calculator. Make use of it to assist with the design of steel, wood, and concrete beams under various loading scenarios.

However, in this article, we’ll share the best 10 free beam calculators.

What is a Beam Calculator?

A beam calculator is a virtual tool, often found online, that engineers and construction professionals use to analyze beams. Imagine a shelf holding books – that’s a beam!

These calculators take into account the beam’s material (wood, steel, etc.), size, and how it’s supported (resting on two walls, one wall, etc.). You also input the weight it needs to hold (the books on the shelf).

The calculator then provides crucial information like how much the beam will bend (deflection) and where the greatest stresses are concentrated. This helps ensure the beam can safely support the intended load without breaking or sagging.

What are Beam Calculators Used For?

Beam calculators are the unsung heroes of the construction world. These digital tools assist engineers and builders in ensuring that beams – the horizontal elements that support weight – can safely handle their intended loads.

Imagine a shelf laden with books. That shelf is essentially a beam! Beam calculators take into account various factors like the beam’s material (wood, steel, concrete), its dimensions (length, width, height), and how it’s supported (resting on two walls, one wall only, etc.). You also factor in the weight the beam needs to support (the books on the shelf).

The calculator then performs complex calculations to predict the beam’s behavior. It estimates how much the beam will bend (deflection) under the load and identifies areas where stress is most concentrated. This vital information helps engineers determine if the chosen beam is strong enough.

By preventing beams from breaking or sagging excessively, beam calculators play a crucial role in ensuring the safety and stability of structures.

7. BeamGuru Beam Calculator

This free beam calculator is designed to calculate beam deflection, bending moment, and shear force for single-span and continuous beams. It supports both metric and imperial units and provides detailed results that can be easily printed or saved.

For any statically determinate (most simple supported and cantilever beams) and statically indeterminate beams, frames, and trusses, BeamGuru is an online calculator that generates Bending Moment Diagrams (BMD), Shear Force Diagrams (SFD), and Axial Force Diagrams (AFD). Most other calculators lack this feature that allows for complete customization to fit most beams, frames, and trusses.


You may model up to three continuous spans and two end cantilevers using this free beam calculator. To enter the dimensions of the beam’s cross-section, the number of supports, the span lengths, and the kind of supports—fixed or pinned—use the Geometry tab. Beams can be rectangular, T-shaped, spandrel-shaped, or L-shaped. 

With ASDIP, it is possible to provide a variety of various load types, including uniform loads, changing loads, concentrated loads, and bending moments. Any span can use the spread loads partially. To enter the load information per span, select the Loads tab. From the Segment drop-down menu, choose the span. The loads can either be a set of nominal load scenarios that will be internally combined or pre-combined loads (no additional load factors). The external loads can readily be increased by the beam’s self-weight.

ASDIP offers two versions, the full version determines deflections, design concrete, and steel, full reports, structural strength, design composite beams, design specific load combinations, schedule beams, and more! While the trial version has a few minor restrictions, such as print and save, enables 15 days of testing for all ASDIP applications.
