Portfolio cost calculator

Author: Leo Kobes Published: Updated: Product information last verified: 22 July 2026

This calculator shows you what your domain portfolio costs per year – and how your arithmetic cost basis changes if the number of domains you enter is no longer renewed. All input stays local in your browser.

The calculator requires JavaScript. The calculation itself is simple: number of domains × average renewal cost = annual costs. Subtract the domains you delete or hand over, and you get your remaining arithmetic cost basis.

What the calculator deliberately does not do

It does not forecast any sale proceeds and does not claim that Redomain "saves" or brings in a specific amount. A Redomain submission ends future renewal costs – whether any proceeds ever arise is not guaranteed. What is shown are purely arithmetic scenarios based on your input.

And then?

How you decide per domain between keeping, developing, selling, Redomain and deletion is explained in cleaning up your domain portfolio. Before a submission, there is no way around the Redomain checklist.
