The link you provided gives me an empty Azure Calculator.
Keep in mind that the VM calculator only gives you the compute hours and storage costs.
It does not give you a price indication on storage IOPS and outgoing traffic costs. Also you may need an public IP or site-to-site/point-to-site VPN to access the VM and maybe a backup which all costs some money.
Azure is a massive big cloud platform which maybe not the place to be when you just want 1 VM.
I recommend reading some basics about Azure to get a better understanding https://learn.microsoft.com/en-us/learn/paths/azure-fundamentals/
