Permutation calculator


The permutation calculator below will help you find the number of permutations.

Use it only when the order of things is important.

Example of permutation

A club has 20 members

The members want to elect a president and a vice-president to be in charge of the club

Here order does matter since being the president of the club is more important than being the vice-president. To find out how many different ways you can elect a president and then a vice-president, use the permutation calculator above

Just type in the box 20 , 2

20 means number of people in the club

2 means number of people in charge
