Domain registration renewal price

if I want to transfer domain from another registrar, what would be cloudflare’s annual renewal fee?

Welcome to the Cloudflare Community. :logodrop:

There is no published price list. Cloudflare only offers at-cost domain registration. This means that you will pay what the registry charges Cloudflare. This will vary by TLD and could change over time if the registry alters their pricing.

Note that Cloudflare registrar is provided as an exclusive benefit for domains that use Cloudflare nameservers. Nameservers of domains that use Cloudflare registrar cannot be changed.
