All the methods are listed here will show contraceptive effectiveness for when used 'perfectly' and when used 'typically'.

Perfect Use.

This is when the contraceptive method is used 100% correctly as stated on the box.

Typical Use.

We are humans so we are bound to make some errors which is why we need to account for this in the stats. For example, missing a pill, or being sick on the pill or getting the injection later than you need to.

Some methods do not have typical use rates because they have no user failure (like the coil).

These stats are sourced from the NHS website.
