ICANN - Internet Corporation for Assigned Names and Numbers

I think it depends where you are getting your domain from some places are free, because they give you a free domain.

on the website you asked:

(the Internet Corporation for Assigned Names and Numbers)

The ICANN charges a mandatory annual fee of $0.18 for each year of domain registration, renewal or transfer. This will be added to the listed price for some domains, at the time of purchase.

The ICANN fee is charged per domain name registration year. For example, the fee for a one-year .com registration would be $0.18 while it would be $0.36 for a two-year .com registration.
