Spring Calculator Professional is for calculating safe and effective springs day in day out. It is the World's smartest spring calculator software packed with data.

What our customers love about SCP...


Backed by real-world data

​Spring Calculator Professional (SCP) is based on over 7 decades of real-world research in our testing labs, giving you access to a wide range of fatigue cycle life and relaxation predictions.


Unbeatable Choice

There are more than 300 material grades included, covering many specifications from all over the world. This includes BS, EN, JIS, ASTM, ISO and others. See the full list here.


SCP is fully Flexible

Choose from the most popular spring types: compression, extension, torsion, conical, rectangular wire and non-standard. Pay only for the ones you need and not the ones you don’t.


Adaptable and insightful

Define your own units and adjust the interface to your needs.  Modify output files to match your company's style and export to Word, Excel, CSV or Text file. Gain valuable business insights through our Data Reporting tool.

Easily Visualise Complex Springs

3D drawings give a realistic visualisation of your spring. You can animate between any two operating positions to help understand how the spring behaves – particularly useful for compression springs of non-standard shapes where coils contact and become inactive.

Non-standard visual editor

It can take a lot of trial-and-error to design a non-standard compression spring. The visual editor minimises this by allowing you to drag around the shape of the spring, seeing the effects on its shape and load-deflection characteristics in real-time.

Material data

What really makes Spring Calculator Professional powerful is access to the data gathered in our testing labs. With this data you can predict the behaviour of your spring over time, in terms of fatigue cycle life and relaxation estimations.


Stress Animations

For non-standard and conical compression springs, you can select two additional animation display modes: see which coils are active/inactive, or see how stress varies along the spring – useful to identify “hot spots” in the design where changes need to be made.
