Most generally, the mechanical advantage is calculated thus:

MA = (the distance over which one must apply the force)/(the distance one wishes to move an object)

This requires an ideal simple machine, meaning that there are no losses due to Friction. This formula can be derived from the idea of conservation of energy.

Mechanical advantage can also be calculated using the laws of classical mechanics, especially the idea of torque.
