Helical Compression Spring Design Equations and Calculator

Spring Design Menu | Spring Suppliers and Manufacturers

This Helical Compression Spring Design Equation will determine force from the given variables.

Force (F) = k(DStanding - DDeflected)


F = Force exerted on spring (lbs)

DStanding = Free length of spring (inches)

DDeflected= Length of spring with force applied (inches)

k = Spring constant determined by experiment or calculation (Calculate k Constant)

Compression Spring Design Suggestions:

Spring rate can be measured by taking the difference in force at 80% maximum deflection and 20% minimum deflection and dividing by the difference in deflection. The spring rate tends to be constant over the central 60 percent of the deflection range. Because of end-coil effects, the first 20% of deflection range has a considerably lower spring rate. The final 20% of deflection shows considerably higher spring rate. When designing for a particular spring, design for critical loads and rates to be within the central 60% deflection range. Standard and custom springs are available.
