Don't think there is one. If you browse the key words "force multiplier definition," you'll find all kinds of defintion, but they are military definitions, not physics.
What you may be thinking of is something called mechanical advantage. The simplest example of this is a bar on a fulcrum. If the bar is 10 feet long, the fulcrum is put 2 feet back from the far tip, you will have a 4:1 mechanical advantage.
This is found by balancing the force times leverage; as in fX8 = FX2; so that F = (8/2)f, which means the effect of pushing down on the long end with, say, f = 10 pounds of force is to have F = 40 pounds of force pushing up on the small end of the bar. It's this mechanical advantage that is employed when using a crowbar or heavy plank of wood to rescue people trapped under a heavy load.
