The whole spiel of AWS (and GCP, Azure, etc.) is to hide the costs behind pricing tiers and service categories. You cannot pay a single price per service but you need to pay for bandwidth, requests, and disk space or computing time separately for each service.

Even AWS salespeople will not give you a price because it heavily depends on your usecase.

I don't know about AWS, but GCP has a price calculator tool.

All cloud providers have calculator tools to give you a feeling about being informed but you can theorize as much as you want, reality will be different. There are just too many variables to consider.
