How to use the Mechanical Advantage Calculator

The Mechanical Advantage Calculator works out your mechanical advantage in an instant. Enter load (output force) and effort (input force) and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the load (output force).
  2. Enter the effort (input force).
  3. Read off your mechanical advantage — the calculator updates automatically, with no button to press.

Formula

The Mechanical Advantage Calculator uses the formula:

Mechanical advantage = Load (output force) ÷ Effort (input force)

Worked example

For example, with load (output force) of 500 N and effort (input force) of 100 N, the mechanical advantage is 5.0000.

Inputs used
Load (output force) 500 N
Effort (input force) 100 N
Results
Mechanical advantage 5.0000

Frequently asked questions

It is how much a machine multiplies force: load divided by effort. Lifting 500 N with 100 N of effort gives an advantage of 5.

Yes. A larger mechanical advantage lets you move a bigger load with less force, usually over a longer distance.

Levers, pulleys, gears, ramps and screws all provide mechanical advantage.

Yes. Greater force usually means moving through a greater distance, since work is conserved.

The Mechanical Advantage Calculator uses the formula: Mechanical advantage = Load (output force) ÷ Effort (input force). For example, with load (output force) of 500 N and effort (input force) of 100 N, the mechanical advantage is 5.0000.
