Let's say that you want to move your domains to a new, amazing platform that's hot recently.
The old platform is buggy and slow but still serves the purpose. It'll slap a 30% commission on you if you don't point your NS to it (outrageous).
Here is the formula you should use to price your domains to get the same outcome:
First, let's calculate the net proceeds you'll get if you sold your domain on the new shiny platform.
Net = List × 0.95 (100 - commission), which is 5%
Net = 4888 × 0.95 = 4643
We also want 4643 if the domain gets sold on the old buggy, unresponsive, greedy platform.
List = Net / 0.70 (in case of 30%)
List = Net / 0.75 (in case you disabled the button that does absolutely nothing 15% + 10%)
So the list price comes to:
4643 / 0.70 = 6632 (30%)
4643 / 0.75 = 6190 (25%)
Those should be your listing prices on the old platform.
This is not advice. Do what you want to do.
