How can I predict my cloud costs?

I want to use a cloud server for my website, but there is no specific fixed amount for this service, as it depends on various factors. Such as which cloud service I will use, what resources I need, and so on. Calculating this every time for each company to find out the approximate price is very tiring.

What type of site do you have? I personally use https://lifeincloud.com/products/dedicated-cloud-servers/ for my online store. Before I installed my cloud server, I was able to calculate the price I have to pay each month for using it. They provide plenty of bandwidth egress starting from 4 TB and you also get NVMe SSD regardless of which plan you choose. I think this is the most profitable option on the market so far.
