If you scroll a bit on the Backblaze B2 pricing page, they have an easy calculator that will tell you exactly what the costs will be.
$0.005/GB/Month for storage
$0.01/GB for egress
The only "hidden" cost I'd say they have is they have a limit on some API calls. For example their b2_download_file_by_name is limited to 2500 calls per day and then $0.004 per 10k calls after that.
