Enter the force (N) and the vertical displacement (m) into the Leaf Spring Rate Calculator. The calculator will evaluate the Leaf Spring Rate. 

Leaf Spring Rate Formula

The following two example problems outline the steps and information needed to calculate the Leaf Spring Rate.

LSR = 2*F / D

  • Where LSR is the Leaf Spring Rate (N/m)
  • F is the force (N) 
  • D is the vertical displacement (m) 

How to Calculate Leaf Spring Rate?

The following example problems outline how to calculate Leaf Spring Rate.

Example Problem #1:

  1. First, determine the force (N). 
    • The force (N) is given as: 500.
  2. Next, determine the vertical displacement (m). 
    • The vertical displacement (m) is provided as: 2.
  3. Finally, calculate the Leaf Spring Rate using the equation above: 

LSR = 2*F / D

The values provided above are inserted into the equation below and computed.

LSR = 2*500 / 2 = 500 (N/m)


Example Problem #2: 

For this problem, the variables required are provided below:

force (N) = 500

vertical displacement (m) = 1.5

Test your knowledge using the equation and check your answer with the calculator..

LSR = 2*F / D = ?
