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)

To calculate the leaf spring rate, multiply the force by the vertical displacement.

## 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
