How to calculate mechanical advantage

Mechanical advantage measures how much a simple machine multiplies an input force — the ratio of output force to input force.

How the calculation works

Mechanical advantage = Output force ÷ Input force.

Example

An output force of 200 N from an input force of 50 N: 200÷50 = 4, meaning the machine multiplies force by 4 times.

Frequently asked questions

How is Result calculated?

Pro Tips for Mechanical Advantage

  1. A mechanical advantage greater than 1 means the machine multiplies force (at the cost of needing to move the input a greater distance); less than 1 means it multiplies speed/distance instead.
  2. This ratio applies to all simple machines — levers, pulleys, inclined planes, gears — though the underlying geometry determining the ratio differs for each.

Common Mechanical Advantage Mistakes to Avoid

  • Assuming mechanical advantage means 'free' extra force with no trade-off — by the principle of conservation of energy, a machine that multiplies force always requires moving the input through a proportionally greater distance.
