Cloudflare R2 vs Amazon S3: object storage cost

Pick what you run and enter your monthly traffic. We work out a full monthly bill for every VPS and cloud plan: the traffic the plan includes, what you pay beyond that, and what object storage and a CDN would add. The cheapest complete setup comes first.

What are you running?

Server size

Images, downloads, video: files that are the same for everyone. Object storage or a CDN can send them instead of your server, so they don't use its traffic.
