Why we built these tools

Most domain decisions come down to numbers: what a name really costs over five years, what you actually net after commission, whether a flip is profitable after renewals, and how risky a name is from a trademark standpoint. These tools put those numbers in front of you before you spend money. For the methodology behind them, see our appraisal guide and domain flipping guide.
