There is no definitive formula for determining domain name value. To do a proper domain appraisal it requires an in-depth understanding of market trends, sales of comparable domain sales and industry expertise.
There are three main factors that influence the sales price of a domain name. Think of these like levers that can be moved independently of each other but add to the value of your domain.
Perceived value is what moves the market. For example, you have a plot of land, let’s say 20 acres. A real estate developer comes along to you and says, “Hey, I’ll give a premium on the market because I can put 40 houses on this land. I’ve done this multiple times and in multiple cities.
