This is what characterizes the deformation of a compression spring relative to the force applied. In essence, it measures the difficulty of compressing the spring. Hence, for a spring with a linear …

Calculate the force required to compress or extend springs using our Spring Rate Calculator in lbs/in or N/mm units.

How to Calculate Spring Rate To calculate the spring rate necessary to meet your working loads, simply divide the load applied to the spring by the expected travel or compression distance.

Nov 3, 2025 · Learn how to calculate spring rate for compression springs and how James Spring ensures precision, reliability, and performance.

Spring rate is the constant amount of force a spring exerts per unit of distance it is compressed (or extended). Essentially, it measures the stiffness of the spring, how hard you have to push or pull the …

Simplify your math with this easy-to-use Spring Rate Calculator... for engineers, mechanics, and spring manufacturers to determine spring rate from actual force and deflection measurements.

This calculator will determine the spring rate constant related to a compression spring from basic geometry and material data input. Default units are shown in inches, etc however SI (metric) can be …
