The domain cost is probably 90% of what it costs to host a web site. The problem with sub-domains is you have a weaker ownership and much higher risk compared to owning a .com domain, it's not like Verisign will shut down anytime soon and take all .com domains with them. I would be surprised if the sub domain you used in high-school still exists and links to your webpage. I also used to run a few web pages on free hosting in high-school, but they have been shut down a long time ago, so the links no longer works. But at least I still have some of the source code saved. After posting I found the .free TLD. I hope it will be like Letsenccrypt, but easier.
