About this calculator

Calculate mechanical advantage from output and input force.

Enter valid values, choose the units you need, then select Calculate. The calculation runs in your browser and does not require an account.

How to use this calculator

What to enter

Enter or select the following as requested: Output force; Input force; Result unit. Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The engineering result is calculated from the dimensions, loads, material properties, flow conditions, or operating values entered. Check the unit system, material assumptions, boundary conditions, safety factor, and whether the model represents static, dynamic, or ideal conditions.

When to use it

Use this for preliminary engineering calculations or to check a worked problem. Verify assumptions and applicable design standards with a qualified engineer before using the result to design, size, or operate load-bearing or safety-critical equipment.
