Yes- AWS calculator: 1) S3- cost for how much you're storing in glacier and then the cost for its metadata to he in a S3 hot/warm tier. 2) Glacier retrieval cost- can be minimized by letting AWS pull it on their schedule. 3) BANDWIDTH- this is the vast majority of the cost at $0.09/GB. There may be ways to lower this, but I haven't tried them.

I'm not saying its a bad deal, I very much wish I'd gone with deep archive (especially with the recent addition of "update if different" to the API)
