Cost of domain name tends to be cheaper with more obscure Top Level Domains (TLDs). .com .org .net TLDs are expensive because they are popular and high in demand. You have to rent them out most of the time. Many are already claimed so you either have to buy the owner out or wait till they stop paying and it expires if you really want it, .xyz is very cheap and uncommon on the other hand thus pennies on the dime per year to rent. Also depending on where you live and your occupation you can actually get a domain name for free through registering with specific services that actually for real own the Top Level Domains. If you are a citizen of a certain country you can get a .us or .cad or .eu .ml domain ect either for free or very very cheap.
