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 …

The spring rate calculator can help you obtain the spring rate (spring constant) for any given spring.

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

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

Compression spring formulas including spring index formula, Wahl factor formula, spring rate formula, shear stress at spring body formula, spring outer diameter at solid height formula, spring stability …

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 …

In mathematical terms, Hooke’s Law is expressed as F=-kx, where F is the applied Force, k is the spring constant, also called spring rate (R), and x is the displacement, also called deflection. This equation, …

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.

Jun 2, 2025 · The formula calculates the spring rate based on the physical properties of the spring, regardless of whether it’s being compressed or extended. The key is to accurately measure the wire …

To calculate the required spring rate to meet these working loads you’ll have to divide the load by the distance traveled as shown in the following diagram and formula.
